Vim li cas Kev Ua Npuas Ncauj Ua Tau Zoo yog qhov tseem ceeb rau kev tua hluav taws zoo

Qhov tseeb ua npuas ncauj proportioning yog ib qho tseem ceeb uas yuav tsum tau ua kom ua tau zoo ua npuas ncauj -raws li kev tua hluav taws. Ua npuas ncauj yuav tsum tau tov nrog dej ntawm qhov sib piv -feem ntau 1%, 3%, lossis 6% - los tsim cov tshuaj ua npuas dej uas muaj peev xwm tswj tau thiab tua cov nplaim hluav taws kub.

Thaum ua npuas ncauj concentrationqis dhau lawm, cov ntaub ntawv tsim tawm tsis muaj qhov nthuav dav thiab ruaj khov, ua rau lub ntsej muag tsis zoo thiab txo qhov kub hnyiab - rov qab ua haujlwm. Cov txheej ua npuas dej tsis muaj zog no tuaj yeem ua tsis tau cov nplaim hluav taws xob, ua rau muaj kev pheej hmoo ntawm hluav taws kub - ignition. Thaum lub concentration yogsiab dhau lawm, ua npuas dej tawm ua haujlwm tsis zoo, ua rau muaj kev noj ntau dhau, cov nqi khiav lag luam ntau dua, thiab muaj peev xwm tsim cov khoom seem hauv lub cev.

Qhov tseeb ua npuas ncauj proportioning kuj tseem ceeb heev rau ua tau raws li cov qauv kev tiv thaiv hluav taws xws liNFPA 11thiab ua raws liFM lossis UL pom zookev tsim qauv. Daim ntawv thov tus nqi, lub sijhawm tso tawm, thiab kev ua haujlwm ntawm lub cev yog suav nrog raws li qhov tseeb ua npuas ncauj concentration. Ib qho kev sib txawv ntawm qhov piv txwv tuaj yeem cuam tshuam qhov kev pom zoo thiab kev lees txais nyiaj pov hwm.

Nyob rau hauv siab - ib puag ncig muaj kev pheej hmoo - suav nrog cov chaw siv roj thiab roj, cov chaw tshuaj lom neeg, cov chaw nres tsheb roj, cov hangars dav hlau, thiab kev teeb tsa hauv hiav txwv- kev ntseeg tau yog qhov tseem ceeb. Precise foam proportioning ua kom muaj kev tiv thaiv hluav taws zoo ib yam nyob rau hauv qhov sib txawv ntawm qhov ntws thiab qhov siab, ua rau nws yog qhov tseem ceeb hauv kev tiv thaiv hluav taws tag nrho thiab kev nyab xeeb.
