Disposable mask quality control inspection service

Disposable mask quality control inspection service

Inspection items of various face masks quality inspection: filter efficiency test, quality test, tightness, air tightness, active carbon component test, microorganism test, ethylene oxide residue, dust resistance efficiency, filter element test, etc.

From August 1, 2009, gb2626-2006 respiratory protective equipment self-priming filter type particle respirator was implemented, which stipulated that the protection levels for particles were Kn90, kn95 and kn100. The protection levels of oil particles are kp90, kp95 and kp100. The filtration efficiency was 90%, 95% and 99.97% respectively. Kn100 and kp100 are of high protection level. According to the national gb2626-2006 standard, the filter elements of dust masks shall be printed with permanent identification: ‘gb2626-2006-kn100’ national standard, year number and protection grade identification. The higher the degree of protection and filtering efficiency, the higher the safety of the dust mask.

Protection performance for fine particles (PM2.5) The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: Level D, level C, level B and level A. The corresponding use environment is as follows: Level D is suitable for moderate (PM2.5 concentration no more than 150 g / m3) and below pollution, level C is suitable for severe (PM2.5 concentration no more than 250 g / m3) and below pollution, and level B is suitable for severe pollution Dye (PM2.5 concentration no more than 350? g / m3) and grade A are used when PM2.5 concentration reaches 500? g / m3. Wear mask reasonably according to the standard requirements, which can reduce the concentration of PM2.5 inhaled to less than 75? g / m3, and make the air quality in the inhaled body reach good or above level.
