Product Description: The utility-model high-efficiency dust-proof mask can form a filter chamber through a filter membrane and a bracket. The filter area is large. It can play a good role in air filtration in the environment with heavy smoke and dust. It can effectively protect the respiratory tract. Because the shape of the mask matches the shape of the mouth and nose, it can make a good combination of the mask and the human face to prevent leakage. The wearer feels comfortable. KN95 N99 R99 and other filters are used inside the mask. According to the national standard dust concentration, the mask is worn for 8 hours every day and the filters are replaced once every 2 days. The temperature of the wearing environment shall not exceed 80 degrees Celsius. The internal material is KN95 grade filter material, which is a new type of filter material designated by the Research Center of Safety Science and Technology of the State Economic and Trade Commission for exclusive production of anti-N-nitroso compounds. It meets the national standard GB2626-2006 KN95. According to the national standard dust concentration for reference, the wearing environment temperature should not exceed 60 degrees Celsius. Do not use in oily gas environment.
The mask uses an inner and outer N95 filter. The outer layer can intercept more than 5 microns of dust, and the inner layer can block the infection of human respiratory droplets and body fluid secretions.
Scope of application: rubber, fur manufacturing, battery, chemical industry, mining, petroleum, nuclear industry, shipbuilding, crafts, paper making, brewing, crystal, agriculture, petrochemical, environmental sanitation, glass manufacturing and other industries.
The technology of preventing N-nitrous carcinogens by using the exclusive technology designated by the state.
Thickened polymer cotton blending technology can effectively decompose dust for a long time, prolong service life, and make wearers more comfortable and secure.
Note: The best water temperature for cleaning masks is 6 - 20 degrees Celsius. They should not exceed 30 degrees Celsius. They should not be rubbed. Otherwise, they will destroy the internal filter material. Just gently clean the surface dust.
