Self-priming sefa gasi mask: Inovimba nekufema kwemupfeki kukunda kupikiswa kwezvinhu, uye inodzivirira kubva kune muchetura, magasi anokuvadza kana mhute, zvimedu (senge utsi hune muchetura, mhute ine muchetura) nedzimwe njodzi kuhurongwa hwekufema kana maziso. uye chiso.Iyo inonyanya kuvimba nebhokisi resefa kuchenesa zvinosvibisa mumhepo mumhepo yakachena kuti muviri wemunhu ufeme.
Zvinoenderana nechinhu chakazadzwa mubhokisi resefa, iyo anti-virus musimboti ndouyu:
1. Activated carbon adsorption: Activated carbon inogadzirwa nemarasha anopiswa kubva muhuni, muchero nemhodzi, uye yozogadziriswa nemhepo nemakemikari ejenti.Iyi activated kabhoni chidimbu chine isina chinhu chimiro chehukuru hwakasiyana, kana gasi kana chiutsi chikaungana pamusoro peiyo activated kabhoni particle kana mu micropore volume, ichi chiitiko chinonzi adsorption.Iyi adsorption inoitwa zvishoma nezvishoma kusvika gasi kana chiutsi chazadza iyo micropore vhoriyamu yeiyo activated kabhoni, ndiko kuti, yakanyatsozadzwa, uye gasi uye chiutsi zvinogona kupinda mukati meyakagadzirwa kabhoni layer.
2. Chemical reaction: Inzira yekuchenesa mhepo kuburikidza nekushandisa makemikari anonwisa kuti abudise maitiro emakemikari nemagasi ane chepfu uye steam.Zvichienderana negasi uye mhute, zvakasiyana-siyana zvemakemikari zvinotora zvinoshandiswa kugadzira kuora, neutralization, yakaoma, oxidation kana kuderedza maitiro.
3. Catalyst action: Semuenzaniso, nzira yekushandura CO mu CO2 neHopcalite sechinhu chinokonzera, iyo catalytic reaction ye carbon monoxide mu carbon dioxide inoitika pamusoro peHopcalite.Kana mhute yemvura ichipindirana neHopcalite, basa rayo rinodzikira, zvichienderana nekupisa uye kusangana kwekabhoni monoxide.Iyo yakakwirira tembiricha, iyo shoma inoita mhute yemvura paHopcalite.Nokudaro, kuitira kudzivirira kuitika kwehuputi hwemvura paHopcalite, mu carbon monoxide gas mask, desiccant (yakadai seCarbon Dioxide absorbent) inoshandiswa kudzivirira unyoro, uye Hopcalite inoiswa pakati pezvikamu zviviri zve desiccant.
