  2. The color should be consistent with the basic part of the office.
  3. Color matching glass partition wall is part of the whole office environment. The materials can be carefully selected and processed.

The common phenomena of glass partition wall

In the daily decoration of office glass partitions, insulating glass and double glass are commonly used, but people are difficult to distinguish between the two. They often confuse insulating glass and double glass. Although the two have similarities in many aspects, There are some differences in individual performance.

The so-called double glass partition is to replace the traditional single piece of glass with two pieces of glass. Since the air layer between the two pieces of glass is not sealed with an effective sealing material, a large amount of dust and moisture can easily enter the two pieces. Between sheets of glass, double-layer glass is a restricted product in construction. Insulating glass is to separate the two pieces of glass by effective sealing materials and spacer materials, and a desiccant that absorbs moisture is installed between the two pieces of glass to ensure that the inside of the hollow glass is a dry air layer for a long time. There is no moisture and dust; at the same time, insulating glass is easy to be mass-produced industrially, so insulating glass is a large number of recommended products in new buildings.

Insulating glass is an innovation of traditional single-glass partitions. It is a new glass processing technology in the production of modern glass partitions. Although it is composed of two or more glass layers, it is more important to It forms a state of vacuum or gas (such as adding inert gas), so it is called “hollow glass”. The application of this technology greatly improves the sound insulation, heat resistance, sealing, and safety performance of office glass partitions.

It is precisely because of its superior performance and high level of manufacturing technology. The quality of raw glass, aluminum strip, sealing tape, desiccant and other raw materials is high. Some small workshop-style factories have no equipment and conditions for processing, and some are simple. The two layers of glass are used to mix beads. Because if there is no hollow layer, its sound insulation and heat insulation effect is very poor, and dust can easily get in. It is sandwiched between two layers of glass, but there is no way to get it out.

Glass partition function

The function of the clear glass partition wall is to separate the space and make better use of the space. The general glass partition wall uses toughened glass, which has the advantages of wind pressure resistance, cold and heat resistance, impact resistance, etc., so it is safer, firmer and durable, and the damage to the human body after the glass is broken is much smaller than that of ordinary glass. There are three types of materials: single layer, double layer and artistic glass. Of course everything is done according to customer needs. A high-quality partition project should have good lighting, sound insulation and fire prevention, environmental protection, easy installation and reusable glass.

The Selection of furniture for conference room

The working furniture of the conference room is mainly the selection of the conference table, and the selection of the conference table in different conference rooms is also different. For example, the meeting table of the board of directors must be magnificent and solemn, while the general small meeting room can choose a more delicate, modern and precise meeting table.

The decoration of meeting rooms nowadays usually install multimedia systems. For some people, the use of multimedia operating systems is more complicated. Therefore, in order to facilitate the use of everyone, you must pay attention to simple operating procedures when decorating, like smart ones. All system equipment in the conference room of the central control system is relatively centralized and complete, so that it can be effectively combined and used, and the operation process will be more concise and convenient.

In the process of practical selection of white conference tables, we must consider the raw materials of the entire wood conference table and chair sets. To give a simple example, in fact, the existing raw materials are wood or leather, because many black conference tables are in the selection process. Various selection criteria will be considered. When purchasing, you must pay attention to the raw materials of the entire wood. The raw materials of the wood may still be relatively good, and the entire countertop itself is also sealed, because the raw material of the entire wood itself It is also impossible to see. The surface looks like the processing method of the outer surface that we can see. It can be estimated by tapping or weight, and then go to the manufacturer for inspection. The leather custom conference table is basically. It also has better results.

How to maintain executive conference table

If the product has been used for a period of time and there are many abrasions or scratches on the surface of the product, just return to the factory for repair by way of after-sales service. After leaving the factory, it will be like a new product, which can save replacement costs.

Normal maintenance

A. If there is dust on the desktop, first remove the dust with a feather broom, and then wipe it with a clean cloth.

B. Use a clean cloth that is not easy to shed hair for normal maintenance, soak it in water and wring it dry and wipe it. Try to avoid wiping with too hard or rough cloth or dirty cloth to prevent damage to the product surface.

Precautions for conference table for sale

A. Because the conference table uses wood veneer, which is a natural product, the color of different batches of products will have a slight color difference.

B. Try to avoid using oily furniture brighteners, which are easy to chemically change and cause table whitening. When the desktop becomes white, you should return to the factory for repair.

C. If the tabletop is stained with oil, wipe it with a general cleaner. Avoid using products with high volatility of scouring oil to wipe.

D. To keep the coating film intact, avoid placing plastic pads on the tabletop

Three steps for meeting table selection

The positioning of the conference table is based on the company’s size, image and qualifications. If the company is a large company with good qualifications, then the company’s conference table is positioned as a high-end conference table. If the company is small and does not have a certain scale and qualifications at the beginning of its development, then you can appropriately choose a mid-to-low-end conference table sizes. If it is a studio, then downgrade according to the situation.

Determine the size of the conference table heights according to the size data of the conference room. For example, if the meeting room has a larger area, you can choose a custom-made meeting table with a larger size, which not only uses the space but also highlights the atmosphere of the meeting room. If the meeting room is small, you can choose a smaller meeting table appropriately. Of course, you must use the space of the meeting room reasonably, try to place the meeting table in the middle of the meeting room, and look more logical and atmospheric.

After positioning the conference table set, you can choose the material of the conference table. Conventional materials of the conference table are: solid wood conference table, artificial board conference table, MDF conference table, and steel conference table. According to the surface material, it can be divided into: large round conference table, board conference table and steel conference table. High-end conference tables are generally solid wood conference tables and small conference table and chairs, low-end conference tables are generally MDF, white modern office desk and board conference tables, and low-end conference tables are steel conference tables.

In the office decoration, the decoration style and sense of planning of the meeting room are very important. It should be noted that the decoration style of the meeting room should be unified or echoed with the company’s  planning. The meeting room decoration planning style sought by many companies.

Seating of the conference table

  1. Conference table with a podium: This type of meeting is generally used for internal large-scale meetings or external press conferences. The seating arrangement of the podium is that the front row is higher than the back row, the middle is higher than the sides, and the right is higher than the left. The position of the moderator can be in the middle of the front row or at the far right end, and the speaking seat is directly in front of the podium or right in front. The participants face to face with the podium and follow the same seating principle.
  2. Seating for the reception meeting: There are seats for the host and the main guest in the middle of the reception room, the right is the main guest and the left is the main seat; the accompanying persons take their seats in turn.
  3. Audience seat seating: the audience seat is the first to respect and the right to respect; if the seats are taken in order according to the pinyin prefix of the unit and department name, it is also a principle of equal seating.
  4. Lecture-type adjustable height conference table: For small lectures, the format of the conference hall is best arranged as a lecture-type
  5. Rectangular conference table: This kind of custom wood conference table modern style is suitable for internal meetings or bilateral negotiations. When conducting internal meetings, the person with the highest position should be on one side of the short rectangle and should sit facing the door. When conducting bilateral negotiations, the two parties can sit on either side of the long side of the table. The person with the highest position of each party should be in the middle of the position, the person with the second position should sit on his right, and the person with the third position should sit on the left, in order.
  6. Round western style conference table: suitable for internal meetings or multilateral negotiations that avoid the concept of seating. The round table deliberately embodies the principle of equality and mutual benefit among participants, and downplays the concept of respect and inferiority. Although the round table avoids the issue of seat ranking, in accordance with international practice, all participants should try to enter the venue at the same time.
  7. Oval conference table: Suitable for internal meetings, the person with the highest position should be at one end of the oval conference table sale.
  8. U-shaped conference table: suitable for internal meetings and smaller meetings.

3 tips for using portable generator

Transportable Generators are best for modest-to-medium jobs or even emergency backup power. Overloading your generator can seriously harm your useful appliances and electronics. Yet yet another issue to select RV generator is that it is of gasoline or any other type of functional aspect. Never ever attach a portable generator directly to the electrical program of a structure (house, office or trailer) unless the generator has a properly installed open-transition transfer switch. When you are utilizing a neighborhood generators other men and women are also tapping their power from te same supply the voltage could be will be reduce and some higher energy consuming appliance like refrigerator can’t function as a result you want a stabilizer.

Ranges of generator capacity

Additionally, to market sustainable improvement, the CPCB (Central Pollution Manage Board) has prescribed the permissible noise and emission levels for diesel generators, petrol & kerosene generators and LPG & CNG generators which each genset user must comply with. Regardless of whether you are new to the globe of transportable generators or you have some fundamental expertise with the gear, there are a handful of specifics you are going to need to have to preserve in mind when shopping about for the appropriate portable generator.

But when you happen to be traveling, not standard generators but choosing transportable generators is the most clear option. A few of these are building firms that rely most on the comfort and capability of diesel generators to supply the necessary electricity on perform websites. This sort of mining helmet lamp can be applied in flammable and explosive environment such as coal mines, chemical industry, oil and road transportation, also can be applied in other mobile lighting locations.Mining Explosion Proof Lighting Helmet 141 is a new sort of environmental-friendly lamp.

Safety rating of diesel generator

We carry generators for the international industry and EPA Certified for use in the United States. The report contains ten year market forecasts for diesel generator sets, natural gas and option technology industry values each globally and regionally. Diesel-fueled generators are specified due to the fact they deliver outcomes when and where necessary. Power outlets on the unit let you to plug extension cords, electric-powered tools and appliances into it. In basic, the far more powerful the generator, the a lot more outlet combinations are obtainable.

Note: This normal also does not include U.S. power efficiency requirements for electric motors used in hazardous (classified) areas. The generator only supplies power to the load directly. Generators can effortlessly run appliances such as refrigerators, water pumps and televisions, so you are going to always have energy, even if the elecrticity at house is out. Think about paying further for a model with electric, turnkey starting capabilities if you don’t want to be pulling a cord in negative weather to get the unit started.

1.two This common covers the identical variety of electrical gear indicated in 1.1 for installation and use in Class I, Zone 1, Groups IIA and IIB, IIB+H2, and Zone 20 and 21 hazardous areas. The history of the creation of the first gas generator sends us to France at the finish of the 13th century, exactly where the French engineer Philippe Lebon, as soon as throwing a handful of sawdust into the vessel on fire in front of him, he saw a thick smoke rose from the vessel, which broke out on the fire and gave a bright luminous flame.

Prime energy generators have significantly longer operating occasions and can manage bigger loads than backup generators. The Honda 660530 from leading 10 best portable energy generators utilizes a company evaluation motor so you can encounter much more noteworthy efficiency. This ETQ IN3500I 3,500 Watt 149.5cc 4-Stroke Gas Powered Portable Inverter Generator functions great, incredibly advocate it for its sturdiness and exceptionally functional. To test performance and run time on a steady electrical load, we filled every model with 16 ounces of fuel and ran the tanks dry with flailing-arm tube men, which drew a combined 320 watts from their 9-inch blower fans.

This could be the reason the description described it as a “Magic fueled electrical energy machine” in older versions. OOperators ought to guarantee that generators are not overloaded by as well a lot of or too-big appliances it is a excellent safe practice in no way to attach sufficient appliances to exceed 80% of a generator’s running watts. Same as generators do. But as opposed to automobile engines, you cannot refuel generators even though operating or even shortly soon after they are shut down since they stay hot for a extended period of time.

Cost of generator set

A single of the greatest solutions that you can do when electricity is out is to buy portable generators. All-natural gas can be employed to energy generators for operation, either in emergency or on a continuous basis, and is regarded as a single of the most accessible and effective fuels for energy generation, amongst non-renewable sources. Section 355 of the Operate Wellness and Security Regulation 2011 calls for particular controls for prevention of fire and explosion related with hazardous chemical compounds.

They also have a tendency to be not as clean although burning in comparison to the other varieties of fuel generators, though they have gotten greater lately. One more benefit is the availability of help for diesel engines. A portable generator is a gas or diesel-powered device which gives short-term electrical power. Otherwise losing power means losing valuable time and can set you back days, so make sure your diesel generator聽is from Kruger Energy. Powerful, portable, and efficient, the Yamaha EF2000iS Gas-Powered Portable Inverter delivers maximum electrical output without having sacrificing portability.

Causes and hazards of chemical production and static electricity

Static electricity safety is an important part of safety management in the chemical production process. The generation and accumulation of static electricity may cause major safety accidents, seriously affect safe production, and cause significant economic losses. The hidden nature of static electricity causes personnel to pay less attention to the management of static electricity safety. Therefore, be familiar with the causes of static electricity, fully understand the preventive measures of static electricity, implement preventive measures in the chemical production process, improve personnel’s awareness of static electricity safety and safety management level in the production process, so that everyone pays attention to static electricity safety to ensure Production is safe and stable.

Chemical companies often use, transport and store flammable and explosive gases, liquids and solids in the production process. Due to factors such as process formulation deviations, improper operation methods or paralysis of personnel thinking, static electricity will be generated. May cause a safety accident. Combustion and explosion accidents caused by static electricity in the chemical production process are not uncommon, but the quality of products is not up to standard, equipment and facilities are damaged, and serious economic losses, casualties and other adverse effects will be serious. Therefore, understand the causes of static electricity, predict the possible hazards, and take safe and reliable preventive measures to achieve “prevention first, prevent combination”, in order to ensure the safe and orderly production, to achieve the intrinsic safety of the production process.

1 .Causes of static electricity

Static electricity is caused by the transfer of electrons in the outer layer of atoms caused by various external forces to form positive and negative charges, so static electricity is divided into positive and negative static electricity. The main causes of static electricity are friction electrification, contact electrification and induction electrification. The friction between the objects will cause the transfer of charge, which is the electrification of the friction; the objects of two different materials will separate after contact with each other, and the objects will be charged when they are close to the charged objects; when the objects are close to the charged objects, the objects will be charged, which is called induction charging. Static electricity is not a static charge. It is a charge that accumulates on the surface or inside of an object because the generated charge cannot be released in time. When objects of different electrostatic potential are close to or in contact with each other, charge transfer will occur, and the discharge of static electricity will produce electrostatic discharge. If ignition conditions are met, combustible materials will be ignited, causing accidents and casualties.

2. The danger of static electricity

(1) Cause production safety accidents

Most media used in chemical production are flammable and explosive. During the process of material friction stirring, material flow, shaking during media transportation, etc., static electricity will accumulate. The voltage of static electricity can reach 10,000 volts, even 100,000 volts. If discharge occurs, combustibles, flammables, or even difficult Burning materials will also be ignited. The instantaneous discharge of static electricity can also cause dust explosions. The danger of dust explosions is often more shocking. The first explosion of dust will raise more dust, and the second explosion of dust is often more terrible. The human body generates static electricity due to the friction between clothing or between the human body and the clothing during the activity. The strong mobility of the personnel makes the monitoring of the static electricity carried by the human body particularly difficult. Once electrostatic discharge of the human body occurs, it may cause combustibles and combustibles. When a fire or explosion occurs, causing a safety accident or casualties.

(2) Cause production safety failure

Static electricity can cause great harm to safety operations, quality, equipment and production environment. Especially in the process of powder material transportation, static electricity will deposit materials with smaller particle size, adhere to the pipe wall, block the pipeline, the material cannot be transported, and even the pressure of the pipeline and the system rises, which may cause serious damage to the equipment . The discharge of static electricity causes the electronic components of the device to burn out or break down in the computer system or control system, which may cause errors in signal transmission or reception, thereby causing production failures and safety accidents. Static electricity will also accelerate the aging speed of electronic components and shorten their life.

(3) Cause personal injury

Electrostatic shock is not an electric shock through which the electric current continuously passes through the human body, but refers to the shock injury caused by the static discharge instantaneously. Electrostatic shock can cause damage to the human center, nerves and other parts. Electrostatic shock is not caused by the human body directly touching the live part of the charged equipment, nor caused by the failure of the electrical equipment, but because of the contact and separation of the clothes and solid materials during the activities of the person, as well as the static induction and other conditions that make the human body Static electricity is formed, resulting in injury from electrostatic discharge. The damage of static electricity to personnel is uncertain, and special attention should be paid to the static electricity of personnel.

3. Prevention of static electricity

Static electricity has the characteristics of high voltage, low power, low power, small current and short action time, but electrostatic discharge is instantaneous discharge, and often instantaneous power is large. In the chemical production process, safety is the basic condition for obtaining economic benefits. Without safety guarantee, there is no way to talk about production benefits. Often, the economic losses caused by an accident caused by parking will be very large. The generation of static electricity is inevitable. How to reduce the generation of static electricity and release the accumulated static electricity safely in time to eliminate the harm caused by static electricity to ensure that production runs under the premise of intrinsic safety. There are many ways to eliminate static electricity, but the simple and effective measures in the production process mainly include process design control method, static grounding method, static neutralization method and anti-static measures for the human body.

4.Process design control method

The process design control method is a simple and effective solution to fundamentally solve static electricity. From the perspective of process design, the elimination of static electricity is to eliminate static electricity from intrinsic safety, mainly in process design, equipment material selection, equipment structure type, and addition of conductive substances Such measures as reduce the generation of static electricity or discharge the generated static electricity in a timely and safe manner. The main measures are: (1) Choose a reasonable material feeding sequence and method: choose the order of different materials feeding order, the reasonable arrangement of the material conveying method or feeding method; (2) Equipment material: choose the material that is conducive to electrostatic discharge according to the nature of the material Conductive materials, avoid the use of insulating materials; (3) The static discharge measures of the equipment are considered in the design process of the moving equipment, and the safe and reliable measures must be taken to guide the static electricity away from the moving equipment during the design process; (4) The material transportation speed and The material and size of the pipe are reasonably matched: the larger the pipe diameter, the smaller the flow rate, and the smaller the pipe diameter, the faster the flow rate; (5) the addition of a charge inhibitor or a high-conductivity substance to promote the dissipation of charge and reduce the risk of static electricity; (6) Electrostatic grounding alarms are installed at the ends of other mobile equipment such as raw material barrels, turnover barrels, tank trucks, etc., and the static electricity accumulated by the mobile equipment can be exported in time.

related systems. The importance of static electricity in chemical production should be paid attention to. It is eliminated by safe and reliable measures, so as to ensure the safe production of enterprises, avoid accidents, and achieve intrinsic safety in the production process.

4 Things You Must Know If You Love Your Car

We spend so much money on the payment, maintenance and repair of the car, and you would think we would have a better relationship with our car. But knowing how our cars work and how to maintain them can be unbearable. All the parts, fluids, guidelines to follow, and things that might go wrong, make cars and garages look scary, but they do not have to be. You do not need to know your car like the back of your hand, but you should have some basic elements. To help you have more confidence in your car owners, here are five things you should know before driving:

The first thing

You need to know about your car is the year it was made, the brand and the specific model. It may seem like a no brainer, but you’ll be surprised how many people don’t know the information. They often make mistakes in years or models, which can lead to major errors. The fluids, parts and accessories needed to repair and maintain a car are based on the year, make and model of the vehicle, so it is important to know the exact information. The design, construction and model of a car will change significantly in a year, and so will the parts you need for your car.

The second thing

The best way to keep your car running well is to follow your car’s specific maintenance plan. Your schedule will tell you when to change the oil (no longer 3000 miles or every three months), when to check the fluid, and when to rotate the tires. Each vehicle has its own maintenance plan, which should be followed to maintain optimum performance, health and life. Your maintenance schedule is in your owner’s manual or in a separate manual that comes with your owner’s manual. Read carefully and check and replace the parts or fluids in the vehicle strictly according to the recommendations.

The third thing

Proper tire pressure is probably the most neglected maintenance problem for our cars. When the indicator light on the dashboard is on, we usually wait until the tank needs to be filled. That is when we did not have a breath, or we just didn’t want to. To be honest, I hate to inflate my tires as much as I hate refueling, but ignoring this light only makes it easier for us to flat or blow out, pick up nails on them, or wear our tires faster. Stop this bad habit now, because it will shorten the life of our tires and force us to buy them more frequently. Tires are expensive, but some tires can last more than 50,000 miles if you maintain them properly. On the other hand, make sure you don’t top up your tires!

The fourth thing

Your vehicle identification number (VIN) is the fingerprint of your car. It’s a 17 digit number that identifies your car’s date of manufacture, location, make, model, engine size, etc. The vehicle identification number (VIN) will follow the vehicle throughout its service life. You need to know where to find the number, but you don’t need to remember it. The easiest way to find it is to stand outside the car, on the driver’s side, and look at the corner of the dashboard, where it hits the windshield. Your VIN is useful when talking to machinery and insurance companies. If you want to buy a car or buy parts for it, you can use your vehicle identification number to find information.

What is plant extract

Plant extracts refer to substances that are extracted or processed from plants (all or part of plants) using appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, health industry, beauty industry, and other industries.

Product definition of plant extracts

Plant extracts use plants as raw materials. According to the needs of the use of the final product extracted, through physical and chemical extraction and separation process, one or more effective ingredients in the plant are obtained and concentrated without changing the effective ingredients. Structured products. According to the different components of the extracted plant, glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc. are formed; according to different properties, they can be divided into vegetable oils, extracts, powders, lenses, etc.

Market supply and demand of plant extracts

There are many different varieties of plant extracts. The supply and demand of these products are constantly changing with the year and various market factors, and the imbalance between supply and demand occurs from time to time.

1. Product supply impact As the raw materials of the plant extract industry are agricultural and forestry products, they are susceptible to weather, plant diseases and insect pests, planting area and other factors. The purchase price and quantity of raw materials in different years will fluctuate, and the price of raw materials will fluctuate the price of natural plant extract products. 1. The output will change to a certain extent, and market supply and demand imbalance will occur.

2 Market demand impact

Most production companies have limited knowledge of overseas market demand, and may lack scientific and long-term accurate judgment on market demand. When the market demand for a certain product is good, there will be a market imbalance in short supply, but with the spread of market information, a large number of enterprises will swarm and repeat production, resulting in product supply exceeding demand.

Ingredients of plant extracts

1. Alkaloids

It is a complex nitrogen-containing organic compound with special physiological activity and medical effects. For example, ephedra contains ephedrine for the treatment of asthma, and scopolamine contains antispasmodic and analgesic effects.

2. Glycosides

Composed of sugar and non-sugar materials. The commonality of glycosides is in the sugar part. Different types of aglycones have different physiological activities and have many functions. For example, digitalis leaves contain cardiac glycosides, and ginseng contains ginsenosides for qi, shengjin and soothe the nerves.

3. Volatile oil

Also known as essential oil, it is an oily liquid with aroma and volatility. It is a mixture of various compounds. It is physiologically active and has many functions in medical treatment, such as cough, asthma, sweating, anti-extension, expectoration, and expelling Wind, analgesic, antibacterial, etc. Among the medicinal plants, the volatile oil content is rich in Platycladus orientalis, Magnolia officinalis, Xinyi, camphor tree, cinnamon Evodia, Angelica dahuricae, Chuanxiong, Angelica, mint and so on.

4. Tannin

A mixture of polyphenols. Exist in a variety of plants, especially in the Salicaceae, Fagaceae, Polygonaceae, Rosaceae, Leguminosae, Myrtaceae and Rubiaceae plant content. The gall gall medicinal material produced on the medicinal plant salt skin is called gallnut, which contains gallnut tannins, and has the functions of astringent, antidiarrheal and antiperspirant.

5. Other ingredients

Such as sugars, amino acids, proteins, enzymes, organic acids, oils, waxes, resins, pigments, inorganic substances, etc., each have special physiological functions, many of which are important clinical drugs.

Based on the legislative categories and concepts of various countries and their usage, the concept of plant extracts can be accepted and recognized by various countries, and it is also a common expression used to spread herbal medicines in various countries. The export value of Chinese plant extracts exceeded the export value of Chinese patent medicines as early as 1999. In the European and American countries, plant extracts and their products (plant medicines or food supplements) have a broad market prospect, and have developed into an emerging industry with annual sales of nearly 8 billion US dollars.

The plant extracts in China are generally intermediate products, which are currently widely used, mainly used as raw materials or auxiliary materials for medicines, health foods, tobacco, cosmetics, etc. There are also many types of raw material plants used for extraction. At present, there are more than 300 plant varieties that have been extracted industrially.

Mask Knowledge You Need To Know

Mask is a kind of sanitary product, which is generally used to filter the air entering the mouth and nose, so as to block harmful gases, smells, droplets, viruses and other substances, and is made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, and when working in dust and other polluted environment, wearing masks has a very good effect. Masks can be divided into air filter masks and air supply masks.

Developing process of face mask

In March 1897 , a German, introduced a method of wrapping the nose and mouth with gauze to prevent bacteria from invading. Later, someone made a six layer gauze mask, sewed it on the collar, and turned it over to cover the nose and mouth. However, this kind of mask always needs to be pressed by hand, which is extremely inconvenient. Later, someone came up with a way to tie the tape to the ear, which became the mask that people often use today.

In 2003, the use and popularization of masks reached a new climax. A “SARS” almost made masks out of stock at one time. There was a long line in front of every drugstore, and people rushed to buy masks.

In 2009, after the “bird flu” in 2004, the “A H1N1 flu” made the mask army appear in front of the world’s major news media again.

In 2013, the emergence of PM2.5 air hazard concept caused the public to pay attention to air pollution, making masks and other protective equipment very popular during the haze weather.

On February 7, 2020, in the disinfection supply center of the Second Affiliated Hospital of Xi’an Jiaotong University, more than 30 medical staff and volunteers made masks by using medical packaging non-woven fabric, absorbent paper for instruments, N95 melt blown filter cloth and other materials.

Classification of face mask

Some of the carriers of the particles are oily, and these substances attached to the electrostatic non-woven fabric will reduce the electrical property and make the fine dust penetrate. Therefore, the filter material to prevent the oil-bearing aerosol should be subject to special electrostatic treatment to achieve the purpose of preventing the fine dust. Therefore, each series is divided into three levels: 95%, 99%, 99.97% (referred to as 95, 99, 100), so there are nine categories of filter materials.

Selection method

The efficiency of respirator is based on its barrier efficiency to fine dust, especially to respirable dust under 2.5 μ M. Because this particle size dust can directly enter the alveoli, which has the greatest impact on human health.

Gauze mask, its principle of dust prevention is mechanical filtering, that is, when the dust collides with gauze, through layer upon layer of barrier, some large particles of dust are blocked in the sand cloth. For some fine dust, especially dust less than 2.5 microns, it will pass through the mesh of gauze and enter the respiratory system. Dust mask is composed of filter material active carbon fiber felt pad or non-woven fabric. The respirable dust less than 2.5 μ m is blocked in the process of passing through the filter material and plays the role of filtering air.
