The most commonly used mask is used My suggestion
KN95 respirator manufacturers'It is said that this mask can completely protect against PM2. Wearing a mask for a long time will make the nasal mucosa vulnerable and lose the original physiological function of the nasal cavity.' N95, which is a mask standard implemented in the United States.' Li Yan introduced, with a nose clip Masks have better airtightness.
As a respiratory doctor, the most commonly used mask is used My suggestion is that there is no need to panic about smog and PM2. 'I suggest that citizens wear masks as little as possible when they go out. But various masks have different wearing requirements, and you must read the instructions carefully before use. When we leave the ward, we must quickly remove it and suffocate 10 Minutes are unbearable. The nasal cavity and nasal hairs themselves are filtering 'barriers'.' Li Yan, director of the Department of Respiratory Medicine of the First Hospital of Xi'an City, showed the reporter the professional N95 medical mask.' ,. '
With the increase of fog and haze, many people go out and wear masks out of a herd mentality.'Incorrect use can cause illness or even death.3 micron sodium chloride particles, and the barrier rate must be more than 95%.5 particles,' Li Yan said. 'In the SARS in 2003, eight volunteer doctors in Shaanxi wore such masks to go to Beijing to support.5 particles in smog.5 particles'rejected outside the mouth' can only be used as a temporary stopgap measure. If our air quality is not good, even if everyone can use PM2 .' Li Yan warned, 'In fog and haze, you should try to reduce travel as much as possible, and exercise more to increase resistance. The mark on this 3M company 8210 series mask is very eye-catching.
People KN95 respirator manufacturers have vigorous blood circulation in their nasal mucosa. Masks with brackets are more comfortable to wear because they provide breathing space for the nose and mouth. It has great respiratory resistance and no one can fully adapt. But the wearer must undergo professional training. We usually wear it only when we are in contact with very serious respiratory patients. Of course, the improvement of the atmospheric environment is the complete solution. The mask is tested with 0 -
There must be a good filter membrane material
KN90 Respirator factory5. Third, there must be poor ventilation achievements, otherwise it will cause breathlessness and no breathing.So, how to choose ineffective PM2.5 to KN90 Respirator factory the body. Therefore, the professional anti-haze nasal mask on the market today protects PM2. In the actual reservation, due to the loose fit of the mask and the face, the achievement of haze prevention is often greatly reduced.5. It should be more than half an hour I believe that the introduction of this program and the questions and answers of experts will be followed by the public.com';
The article comes from. Gao Xinhui, an engineer, said that the anti-haze products sold in the current market are not countable, but there are very few who can wear Anjing and can effectively prevent haze. In addition, we can protect the nose, the protection of the inhalation path of the atmosphere, and reject the atmospheric poisons in the environment of PM2. Finally, it reminds the masses of the indifferent people, especially the special people, that they must pay attention to protection during the misty days, and avoid the infringement of PM2. If the content of the work, copyright and other topics are involved, please contact us as soon as possible, we will dispose of it in the short time!5 inhaled organs from entering the body.5 and so on. Second, it must have a good fit with the human face, which can achieve good sealing achievements and prevent air leakage. Careful:
The copyright of the articles in this channel belongs to CCTV, and does not mean that this channel echoes its views and Be responsible for its practical burden. 5Has doubled the subjective sense of unilateralism, and has more professional specifications on how to choose anti-haze products. It is also ineffective, which can eradicate the damage of PM2. He pointed out that when choosing anti-fog products, individuals can refer to three points: First, there must be a good filter membrane material, which can effectively prevent PM2. The breathing resistance is very large.
Nowadays, most of the anti-fog masks in the current market and market conditions are predominantly dust masks used in industrial tasks.5 protective equipment? Wang Yuguang, director of the Department of Respiratory Medicine, Beijing Traditional Chinese Medicine Hospital Affiliated to Guodu Medical University, taught that the first thing to look at is the logo, such as anti-haze products with N, KN, and FEB.. Some foreign experts believe that the time of wearing traditional anti-fog masks is not every time -
The usage of the three major parts has been increasing
3-Layer Face Mask FactoryThis phenomenon is in the United States, the Netherlands, Sweden and the United Kingdom. In developed countries such as the United States, Western Europe, Japan, and some 3-Layer Face Mask Factory regions in developing countries, consumers are also advocating the concept of sustainable development and supporting purchase actions.4 billion US dollars. It is unbelievable that in various uses of wipes, after appropriate marketing policies, the sales of adult toilet wipes continue to increase, and now it has become a high-value and growth product.
The usage of the three major parts has been increasing. More adoption of cloth. Because spunlace jacquard does not use thermal bonding between the fibers produced by hot embossing (the fibers are bonded due to the thermal fusion of the fibers, which is difficult to separate in the sewage treatment system), so the flushable wipes It is a very ideal choice. The problem that consumers are reluctant to pay because of the high price of degraded products no longer exists Although the price of wood pulp in the market is close to the highest in history, it is still 50% cheaper than petroleum-based. The difference between the wet wipes in 2013 and 2001 is that all brand manufacturers such as Kimberly-Clark,
Procter Gamble and some mainstream brands of adult toilet wipes are flushable, not small-sized flushable, and the product is completely Meeting the INDA / EDANA guiding rules, it is clear that this change is the role of government regulations rather than the actual needs of consumers. In addition, manufacturers have also noticed that the price difference between cotton fiber and other fibers such as viscose fiber and polypropylene fiber is gradually narrowing.
According to the latest market research report of investment consulting firm Smithers Apex, by 2018, the market's demand for flushable wipes is estimated to be 55,720 tons, with sales of about 1. Due to the spunlace jacquard, the production speed was slowed down, the quality of the jacquard was not high, and investment in jacquard equipment was required. -
The above-mentioned mask statement was formulated by the National Institute
KN90 Respirator CompanyIn terms of data requirements, KN90 Respirator Company require high resistance and low efficiency; P2 products require high efficiency and low resistance. In addition, the EU-standard FFP1, FFP2 and FFP3 industrial masks can also effectively filter out particles or germs. It uses 3. 】N-grade products are mostly American standard.
The above-mentioned mask statement was formulated by the National Institute for Occupational Safety and Health. For example, when the efficiency experiment is used, the particle size of the aerosol sodium salt or DOP oil mist is 0. After passing the sample at a certain flow rate, the instrument automatically prints out Flow rate, resistance, transmittance.2μm (the average diameter of the aggregate is 0. Other masks have a plastic valve, and some do not. There are many micropores in the internal structure of activated carbon that can constitute a very large specific surface area. In the test, the particles with a diameter of 0.
Whether it is a European standard or an American standard, it is specified to use the American TSI-8130 Automated Filter Testers for testing. In its three-layer structure, the needle-punched cloth generally supports the shape of the mask, which is generally called the support layer; the melt-blown layer is the most critical layer, because the indicators of the entire mask data are basically all based on the performance of the melt-blown material.26μm, and the average diameter of the arithmetic is 0. Anti-toxic filter materials generally use activated carbon or chemically-treated activated carbon as a material, and filter poisonous gas or poisonous vapor by adsorption or chemical reaction without being inhaled by people.075 microns were blocked, and the success rate was 95%. The average diameter of the particles is 0. American standard N type uses NaCl method, R type uses DOP method, European standard uses DOP method. In the testing and certification of filter media, the 'worst case' idea is adopted, that is, the conditions when the laboratory performs the testing experiment are set to the worst conditions. In the DOP method, DOP oil is used for dust generation.
Because biological particles are mostly non-oily particles, we use anti-bacterial and anti-influenza viruses for daily use. P series: P stands for oil Proof, which can be used to protect non-oily suspended particles and sweaty oily suspended particles, no time limit. According to customer requirements, the main thing is not the difference in structure, but the data index that the meltblown layer material should reach. -
Residents can choose masks based on daily air quality
Airlaid Paper FactoryThe fog itself is not a kind of pollution.5 index is high, you can choose a medical disposable sterile mask or N95 or N99 mask. The lead bar stuck on the bridge of the nose must be pinched when wearing.

The specific method is to lap the side during construction
Air Through Nonwoven ManufacturersBecause it is made of natural plant fiber non-woven technology, it has stronger tensile strength, more environmental protection, no mold and yellowing, and good air permeability. Do not use a hard scraper or nylon brush after the wallpaper is on the wall. Remember to cut one roll of wallpaper at a time to prevent quality problems. Use a soft brush to gently scrape from top to bottom to smooth the surface of the non-woven fabric to remove air bubbles and wrinkles.
Non-woven fabrics are different from other wallpapers, and the glue should be thicker and thicker than other wallpapers to reduce their fluidity. 5. Construction wallpaper cutting It is necessary to lap and cut the construction. It is a kind of high-end wallpaper / wallpaper. Wall treatment The Air Through Nonwoven Manufacturers wall surface should be flat, clean, dry, uniform in color, and should be free of voids, uneven unevenness, and the wall surface should be treated with a base film (or varnish) before construction.. 6. After the base coat paint is dried during construction, draw a vertical line as the standard to avoid incorrect wallpaper paste position. Do not scrape the glue out of the seam to avoid contamination If you accidentally squeeze out the glue on the surface, immediately wipe it off with a dry towel. Precautions for sticking non-woven wallpaper: 1
. The specific method is to lap the side during construction.Non-woven wallpaper is also called non-woven paper wallpaper. 3. Substrate. Post wallpaper Post the non-woven wallpaper in the order that has been compared in advance. After ensuring that the patterns are aligned, press with a ruler at the overlap to cut, try to avoid cutting at the corners, so as not to cause the wallpaper corners at the corners, make sure the cutter is sharp when cutting, and there should be no burrs At the same time, pay attention to the strength of the knife,
and make sure to cut once and cut twice, but not to damage the surface of the wall too much. Keep your hands as clean as possible during construction. 2. 3. The number of laps depends on the pattern, which is about 3 cm. 2. During the construction, the construction should be checked at the same time. -
The way to improve the charge storage capacity of electret materials
The way to improve the charge storage capacity of electret materialsThe current electrostatic electret methods mainly include electrostatic spinning method, corona discharge method, triboelectric method, thermal polarization method, low energy electron beam bombardment method, etc., among which corona discharge method is currently the best electrostatic electret method.
In the corona discharge method, the melt-blown fiber web is charged with one or more sets of corona discharge through the electrostatic generator needle electrode (voltage is generally 5-10KV) before winding, and the needle tip is charged when a high voltage is applied The air below generates corona ionization and local breakdown discharge. Carriers are deposited on the surface of the meltblown cloth by the electric field. Part of the carriers will penetrate into the surface layer and be trapped by the trap of the electret masterbatch. Become an electret filter material.
Increasing the charge on the surface of the melt-blown cloth can be obtained by the electret treatment process of the corona discharge method, but to make this electrostatic storage not decay, then the composition and structure of the material of the melt-blown electret material is needed to help charge retention. The way to improve the charge storage capacity of electret materials can be to induce charge traps by introducing additives with charge storage properties.
Therefore, Spunbond nonwoven Suppliers with ordinary melt-blown production lines, the production of melt-blown production lines for air filtration materials requires the addition of high-voltage electrostatic discharge devices in the production lines, and the addition of electret masterbatch, such as tourmaline, to the production raw material polypropylene (PP) particle.
