Qhuav hmoov extinguishing neeg sawv cev:
Qhuav hmoov hluav taws extinguishing neeg sawv cev yog tov los ntawm hluav taws extinguishing puag khoom (xws li ci dej qab zib, ammonium carbonate, ammonium phosphate, thiab lwm yam) thiab tsim nyog tus nqi ntawm lubricant (magnesium stearate, mica hmoov, talc hmoov, thiab lwm yam) thiab ib tug me me npaum li cas ntawm ya raws-ntawv pov thawj neeg sawv cev (silica gel). Ua zoo hais, siv cov pa roj carbon dioxide raws li lub dav hlau lub hwj chim.
Hauv paus ntsiab lus ntawm kev txiav txim:
Qhuav hmoov hluav taws extinguishing ua hauj lawm yog feem ntau nyob rau hauv qhuav hmoov tua hluav taws los yog qhuav hmoov hluav taws extinguishing khoom. Thaum lub sij hawm qhov hluav taws kub extinguishing, lub qhuav hmoov yog ntiab tawm los ntawm lub nozzle los ntawm lub siab ntawm lub Pa roj carbon dioxide los yog nitrogen roj mus ua ib lub pos huab hmoov kwj sandwiching lub Pa roj, uas yog raws kev coj mus rau hauv lub combustion khoom. Lub hauv paus ntsiab lus ntawm ib tug series ntawm lub cev thiab kev tshua tshuaj ntawm qhuav hmoov thiab nplaim taws yog raws li nram no:
Lub sodium bicarbonate nyob rau hauv qhuav hmoov yog decomposed los ntawm kev kub. Cov tshuaj tiv thaiv yog ib qho endothermic cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv emits ib tug loj npaum li cas ntawm cov pa roj carbon dioxide thiab dej. Cov dej yog rhuab mus ua pa dej thiab absorbs ib tug loj npaum li cas ntawm tshav kub, uas ua kom txias thiab dilute lub combustible roj; lub qhuav hmoov nkag mus rau hauv cov nplaim taws. Tom qab ntawd, vim yog lub haum thiab tawg ri niab qhuav hmoov, lub tshav kub tawg ntawm cov nplaim taws rau cov roj yog txo, thiab cov evaporation tus nqi ntawm cov kua uas nws txo qis.
