Ntau lawm cov lus qhia
Ua npuas ncauj ua npuas ncauj rau cov quav cawv feem ntau yog cov hluav taws kub tsis sib haum nrog cov roj ntsha uas cuam tshuam nrog cov roj ntsha uas cuam tshuam, tshwj xeeb yog cov neeg muaj dej cawv. Nws ua lub luag haujlwm tseem ceeb hauv kev lag luam xws li petrochemical xws li cov petrochemical, thiab roj cia, uas cov qauv foams yuav ua tsis tau cov hluav taws.
Qhov no mloog zoo, nrog nws cov tshuaj txawv cov tshuaj sib xyaw, zoo li kua av tsaus nti. Nws khav tias yog cov khoom tsim nyog thiab viscosity (tsawg dua los yog sib npaug rau 30 degree)℃thiab sib xyaw hauv hluav taws {}}} be} sib ntaus sib tua tshuab. Thaum tso tawm, nws tsim ua npuas dej nrog cov nyiam kev nthuav dav, uas tuaj yeem muab cov npog zoo thiab cov nplaim taws smwb. The foam's 25% drainage time is sufficient to keep it stable, ensuring fires are suppressed and re - ignition is prevented. Tsis tas li, nws muaj qhov taw tes khov tsawg, ua rau nws siv nyob rau hauv qhov chaw txias tsis muaj kev txhawj xeeb ntawm khov.
Txawm hais tias haus cawv seb puas muaj cov chaw tso tsheb quav cawv, ua npuas dej ua kom muaj cov tshuaj tiv thaiv dej cawv, ua kom muaj zog ntawm cov nyom ntawm cov kev tiv thaiv hluav taws.

Cov FAQ
Q: Ua npuas dej ua li cas rau cov quav cawv uas tsis kam ua rau fluoroproproteIs muaj kev lom zem hauv siab li cas?
A:Nws tswj hwm kev ua tau zoo hauv high - kub kub hluav taws. Cov npaus nws cov peev xwm tuaj yeem tiv thaiv tshav kub kub rau lub sijhawm, pab kom txias cov roj sib npaug thiab cov nplaim taws ua kom sov siab yuav txo qis nws qhov ntev me ntsis.
Lus Nug: Puas yog cov npaus ua npuas ncauj tau siv hauv cov hluav taws txawb - sib ntaus cov chav nyob?
A:Yog lawm, nws tuaj yeem siv hauv cov koog txawb. Nco ntsoov tias chav tso tsheb hlau luam, twj, thiab cov kev siv tshuab tau sib haum nrog lub siab zoo rau cov khoom siv rau kev siv hluav taws kub.
Q: Cov lus pom zoo tau sib xyaw ua npuas ncauj ua kom zoo rau cov quav cawv rau cawv nrog dej?
A:Kev sib xyaw sib xyaw ua ke yog 3% lossis 6% nrog dej, nyob ntawm cov qauv tshwj xeeb thiab hluav taws kub}} kev sib ntaus sib tua. Nco ntsoov hais txog cov khoom lag luam cov ntaub ntawv ua haujlwm rau cov qauv sib piv.
Q: Yuav sim ntsuas qhov ua kom zoo rau cov ua npuas ncauj ua kom zoo rau cov tshuaj txhaum cawv fluoroproprotein ua ntej siv?
A:Kev ua me me - Daim ntawv hluav taws hluav taws hauv kev tswj hwm ib puag ncig, siv cov npaus ntawm cov roj teeb. Qhov no yuav pab txheeb xyuas nws cov hluav taws kub - transmression muaj peev xwm thiab ua kom nws ua tau raws li koj cov kev xav tau.
Q: Qhov teeb meem sib raug zoo nrog ua npuas ncauj - Thov ua cov khoom siv thaum siv qhov kev xav no?
A:Nws yog sib xws nrog feem ntau ua npuas ncauj - kev ua khoom. Txawm li cas los xij, nws raug nquahu kom tshawb xyuas cov khoom siv tsim cov txheej txheem kev ua haujlwm kom ntseeg tau tias kev ua haujlwm ua npuas dej thiab kev ua kom zoo ua npuas.
