How about silicone masks

Everyone knows that the new crown virus basically belongs to the airborne infection caused by droplets, so masks are the key protective equipment for everyone. At present, all types of masks on the market are basically valuable and no market. No matter what kind of masks are already exhausted, and Disposable medical masks have become a luxury, which is difficult for many friends to buy, but anti-gas silicone masks are really a good product. Can silicone masks also become practical protective appliances in this epidemic?

Judging from the current situation, according to many netizens, it is better to take it than not to wear it. Although it is difficult to buy masks in many places, the use of silicone masks in special periods is also a good protective measure. Silicone masks are currently mainly used Coal mines, steel, and dusty ultra-high operating environments can achieve high dust-proof effect, so it is not a problem to choose it as a new crown virus prevention. Silicone masks are mainly based on the principle of the fan. The fan forces the wind to the nose and mouth, increasing the feeling of smooth breathing.

Its protection level is the same as that of the N95 mask, and the middle filter element and the filter are basically the same. However, the current silicone medical supplies category masks basically belong to the principle of electric fans. Therefore, it is recommended that electric masks can be used as anti-virus masks in general public places. Can not be used in areas such as heavily polluted hospitals, because electric masks are forced air or exhaust, much stronger than pure mouth and nose masks, can not completely guarantee the integrity of the airtightness of the mask, and the electric mask filter and other The connection of the parts can not guarantee that there is no gap and no air leakage.

There are many types of masks. The silicone masks are the same. The difference between them is the filter element of the respiratory tract. Different filter element levels can achieve different protection effects.

At present, China's standards for masks cover labor protection, medical protection, civil protection and other fields, mainly including:

GB1.GB2626-2006 Respiratory protective equipment Self-priming filtering anti-particulate respirator;

2. GB19083-2010 technical requirements for medical protective masks;

GB3. GB / T32610-2016 daily protective mask technical specifications;

YY4.YY0469-2011 technical requirements for surgical masks;

5.YY / T0969-2013 disposable medical masks.

The advantages of silicone rubber masks are mainly that the mating surface is silicone. Silicone products have good flexibility and are much more comfortable to wear. They will not scratch the face, but after special tests, it was found that this mask filters PM2. .5 The sealing is normal and it is difficult to drop to 0, so the sealing is still slightly worse. During the epidemic, the use of personal areas is completely fine, but it is necessary to pay attention to the severely infected areas.

Therefore, for the best protection effect, it is best to choose N95 mask without breathing valve. As long as N95 is NIOSH approved, has been tested, and is being used in accordance with OSHA requirements, including proper wear by the user, the wearer should receive the expected protection factors. It should be noted that this mask is designed for use by adult professionals, and this mask is not designed for children. People with impaired respiratory systems, such as asthma or emphysema, should consult a doctor about their use.
