KN95 PARTICULATE RESPIRATOR Suppliers
The transmission rate of ordinary disposable medical masks is 85. These must be scientifically tested in the laboratory with instruments.3 micron particles, the transmission rate of medical surgical masks is 18.5 mask standards are expected to be introduced.6%. 'Antibacterial and anti-haze daily masks' and 'antibacterial and anti-haze daily masks' have been approved by the Quality Supervision Department, and are expected to be upgraded to industry standards or national standards.5 masks cannot be recognized by ordinary citizens' senses.' Geng Limei, director of the Department of Respiratory Medicine of the Provincial Hospital of Traditional Chinese Medicine, told reporters that the better anti-haze effect is the N95 mask.
'In addition to the above two masks, medical surgical masks are also a good choice. Although it feels a little stuffy in the nose and nose, it has no effect on normal work and life.5 microns can reach 95%. .' Geng Limei told reporters that relevant tests confirmed that, according to general medical standards, for 0. The introduction of the standard will change the embarrassing situation of PM2. ,.
'Although the N95 mask has a good filtering effect, it is not suitable for everyone. For special populations, such as children, the elderly, people with respiratory diseases and cardiovascular diseases, they must be worn with caution and should not be worn for too long. Fortunately, PM2.' Geng Limei said that in theory, the more closed the mask's protective material, the better the effect of blocking particles. Conversely, the more closed the mask, the more pronounced the increase in breathing resistance, and the harder it is to breathe. Wearing professional protective masks such as N95 must be trained, otherwise it is easy to cause breathing difficulties and dizziness due to lack of oxygen. N95 is not a specific product name, as long as it meets the N95 standard, it can be called 'N95 mask'.3%.
Industry sources said that the identification of PM2.' Geng Limei said that this mask can capture 90% of particles smaller than 2. At least at present, there is no quality standard for KN95 PARTICULATE RESPIRATOR Suppliers the civilian mask market at the national level. In addition, people with skin allergies caused by masks should also stop wearing them.'Because the PM2. 'If you feel more comfortable wearing N95 masks, you can try KN90 masks. Its filtering effect on particles smaller than 2.5 particles are small, in general, ordinary cotton and gauze masks are difficult to resist. The amount of air a person has to breathe every day is a certain amount, otherwise he will be deprived of oxygen.5 microns.5 masks that 'disorderly flowers gradually become charming eyes'

Progress in 2016 will benefit from the demand for revenue, through the production of personal hygiene products, and in the United States, the United States Driven by the favorable growth of wet wipes, a large market will be maintained. Contour plots can include measurements such as unit weight, air perm, thickness and aperture.
Today, in China, the application of non-woven fabrics is the most critical, such as reverse osmosis membrane support substrates, generally non-woven materials, such as synthetic wet sheeting. The market mix will further fuel price increases, and heavier and more expensive nonwoven materials are in the nondisposables market, many of which are expected to achieve faster gains through 2016 compared to the one-time market is more common. The market for consumables that restricts the production of motor vehicles will continue to account for the largest share of sales revenue, accounting for 68% of the sales demand for nonwovens in 2016. Although the area requirement will come from the greater use efficiency of the car carpet, the volume will increasingly require lower KN95 PARTICULATE RESPIRATOR Suppliers weight components to improve the fuel efficiency of the finished vehicle.
This method can show differences in uniformity, where conventional statistical methods show little or no difference. With the production of customized non-woven fabrics and continuous efforts to optimize the production costs and performance characteristics of nonwoven fabric coils, the growing trend of interest in using various raw materials is particularly important. Because they account for the majority of nonwoven fabric compositions, various fibers are used to form the fabric account for the largest proportion of volume consumed material. It will come from nonwovens, “one-time consumer products with high market penetration, accounting for one-third of the total The consumables market is a consumer market for nonwovens.6% to benefit from 15 billion a year.
Different consumer products, due to favorable demographics, and the production of these products will likely remain close to the point of demand. In the United States, a strong rebound in newly completed homes is driven by good returns supported by non-residential buildings.

For example, two widely spread experiments have drawn two diametrically opposite conclusions: one said that activated carbon had the best effect, and the other said that activated carbon masks were totally unreliable.
Not only that, for some experiments, using toner or thread incense instead of PM2. This makes the dazzled consumers once again fall into the mystery of the constant chaos. Very general. While affirming this statement, Zhang Caiqing also pointed out: 'In the smog, there are not only particles, but also harmful gases such as hydrogen sulfide.' Zhang Caiqing said that N95 masks are only worn by medical staff during the period of avian flu and SARS.' Ms. It can only be said that it is slightly better than a few dollars. Activated carbon can indeed adsorb some gases, but once saturated, it can no longer continue to absorb, and cannot rely on activated carbon to resist PM2. Zhang Caiqing, director of the Department of Respiratory Medicine, Qianfoshan Hospital, Shandong Province, said that these experiments are limited by experimental conditions and experimental methods, and the results may not be credible.5,
Zhang Caiqing also pointed out that the data thus obtained is not scientific. And various experiments on the Internet seem to be difficult to get a convincing result.' Wang Yan introduced that activated carbon does have Adsorption effect, but mainly for odorous gas, and PM2.Whether the anti-fog masks are effective is a big question for consumers. From the perspective of activated carbon alone, Wang Yan, a professor at the School of Environmental Science and Engineering of Shandong University, said: 'Activated carbon masks may have certain effects, but the use of activated carbon to prevent PM2. At the same time, for another popular choice 'N95 mask', Zhang Caiqing is not recommended.5.
The reporter KN95 respirator manufacturers also found in the standard of 'Ordinary Absorbent Gauze Masks' that it is necessary to use the prescribed measuring tools and test methods to detect whether the different parameters meet the standard. 'The effect is quite limited. 'The elderly, children, pregnant women are not suitable for wearing. But it is not as simple as using a simple instrument to get a convincing answer like in a popular experiment
