Ntau lawm cov lus qhia
Tsim nyob rau hauv 3% thiab 6% mloog zoo sib piv, ar-aft foam rau kev sib ntaus hluav taws xob ntxiv: 3% rau kev siv cov kev siv siab, 6% rau cov ntawv thov qis. Ob qho txawv txawv ua rau pom daj daj ntsej muag thiab tus pH ntawm 7.8-8.6, txo cov cuab yeej tua hluav taws hauv kev tua hluav taws. Cov ntawv me me muaj xws li qhov nro muaj tseeb ntawm 15.5-17.0 mn / m (ua kom muaj kev sib kis nrawm dua) thiab ua npuas ncauj nrawm uas ua rau cov khoom qab zib.
Nws cov corner-resistant core ua rau ar-aft foam for hluavtaws sib ntaus tsis tau muaj nyob hauv cov nroj tsuag tshuaj, chaw kho tshuaj, thiab ethanol cia yards. Cov npaus ua npuas dej tseem nyob ruaj khov ntawm -15℃mus rau 45 degree, tswj kev ua tau zoo nyob rau hauv cov tais zaub txias lossis thaj chaw muaj kub. Thaum diluted nrog dej, nws tsim ib daim yeeb yaj kiab dual
Cia yuav tsum tau kaw cov thawv ntim rau hauv cov chaw qhuav, muaj cov chaw muaj kev muaj huab cua, nrog lub neej txee ntawm 10 xyoo nyob rau hauv cov kev tshwm sim. Kev ntsuam xyuas ib txwm-ntawm kev nthuav dav ua npuas dej thiab cov tshuaj lom-kom ua npuas dej-are Rau pab pawg ntsib cov hluav taws polar, cov npaus no sawv ua ib qho tseem ceeb

Cov FAQ
Q: Ua li cas ar-aft ua npuas ncauj rau hluav taws sib ntaus sib txawv txawv ntawm cov qauv AFFF sib txawv?
A: Nws ua rau qeeb qeeb dua li tus qauv Afff vim nws cov qauv tuab tuab, tab sis ua cov kev ua kom muaj qhov pheej yig dua. Rau cov hluav taws kub sib kis no, Khub nws nrog high-flow lub learzles kom nrawm cov kev pab tsis muaj kev cuam tshuam nrog kev haus cawv.
Q: Puas yog cov ua npuas no siv rau hauv cov teeb meem marine tua hluav taws?
A: Yog, tab sis cov khoom siv yaug kom huv tom qab siv. Saladehwater nws tsis demrade nws cov khoom, tab sis seem ntsev tuaj yeem torush-repold kev ua npuas dej rau hluav taws sib ntaus sib tua tau.
Q: Pom zoo rau cov tshuaj tua hluav taws me me tua hluav taws me me?
A: Siv 6% tsom ntsoov rau Handheld chav nyob, diluted nrog 94% dej. Qhov kev sib npaug sib npaug no ua npuas ncauj ua npuas dej thiab qhov tseem ceeb, ua kom muaj txiaj ntsig zoo saws hauv qhov chaw kaw lus zoo li kev kuaj cov chaw kuaj.
Q: Puas yog ar-aft fiab rau hluav taws sib ntaus tseev kom muaj kev kawm tshwj xeeb rau kev nyab xeeb?
A: Kev ua npuas ncauj kev qhia kev cob qhia Suffices, tab sis pab pawg yuav tsum xyaum ua dilution ratio kuaj thiab ua npuas ncauj kuaj. Zam kev sib chwv ntawm daim tawv nqaij nrog cov hnab looj tes zoo-siv cov hnab looj tes, ua cov polymers yuav ua rau muaj kev txob txob me me.
Q: Ua npuas dej ua yeeb yam hauv cov chaw noo ntau?
A: Vaum tsis cuam tshuam nws txoj kev ua tau zoo, tab sis lub khw tsom xam kom deb ntawm noo noo kom tiv thaiv tsis txhob ua. Thaum diluted, foam tseem ruaj khov nyob rau hauv tej yam kev mob noo, ua kom haum rau kev muaj chaw kub.
