Self-priming gas mask: Imadalira kupuma kwa wovalayo kuti igonjetse kukana kwa zinthuzo, komanso imateteza ku mipweya yapoizoni, yowopsa kapena nthunzi, tinthu ting'onoting'ono (monga utsi wapoizoni, chifunga chapoizoni) ndi zoopsa zina pamapumidwe ake kapena maso. ndi nkhope.Imadalira kwambiri bokosi la fyuluta kuti liyeretse zowononga zomwe zili mumlengalenga kukhala mpweya wabwino kuti thupi la munthu lipume.
Malinga ndi zomwe zadzazidwa mu bokosi la fyuluta, mfundo yotsutsa ma virus ndi motere:
1. Activated carbon adsorption: activated carbon imapangidwa ndi makala otenthedwa kuchokera ku nkhuni, zipatso ndi njere, kenaka amakonzedwa ndi nthunzi ndi mankhwala.Izi adamulowetsa mpweya ndi tinthu tinthu ndi dongosolo opanda kanthu kukula kwake, pamene mpweya kapena nthunzi amaunjikana pamwamba pa adamulowetsa mpweya tinthu kapena mu micropore voliyumu, chodabwitsa ichi amatchedwa adsorption.Kutsatsa uku kumachitika pang'onopang'ono mpaka mpweya kapena nthunzi itadzaza kuchuluka kwa micropore ya carbon activated, ndiko kuti, imakhala yodzaza, ndipo mpweya ndi nthunzi zimatha kulowa mu carbon dioxide.
2. Chemical reaction: Ndi njira yoyeretsera mpweya pogwiritsa ntchito zowutsa mankhwala kuti zipangitse kusintha kwa mankhwala ndi mpweya wapoizoni ndi nthunzi.Kutengera ndi mpweya ndi nthunzi, zotengera zosiyanasiyana zimagwiritsidwa ntchito popanga kuwonongeka, neutralization, zovuta, okosijeni kapena kuchepetsa.
3. Chothandizira: Mwachitsanzo, njira yosinthira CO2 kukhala CO2 ndi Hopcalite monga chothandizira, chothandizira cha carbon monoxide mu carbon dioxide chimapezeka pamwamba pa Hopcalite.Pamene nthunzi yamadzi imagwirizana ndi Hopcalite, ntchito yake imachepa, malingana ndi kutentha ndi kuchuluka kwa carbon monoxide.Kutentha kumakwera, mpweya wamadzi umachepa kwambiri pa Hopcalite.Choncho, pofuna kupewa zotsatira za nthunzi ya madzi pa Hopcalite, mu carbon monoxide gas mask, desiccant (monga Carbon Dioxide absorbent) imagwiritsidwa ntchito pofuna kuteteza chinyezi, ndipo Hopcalite imayikidwa pakati pa zigawo ziwiri za desiccant.
