Ntau lawm cov lus qhia
Muaj nyob rau hauv peb tus qauv - AR - AFK 3% (-3 DEGLECE), thiab AF - AFK 3% (-35 degree) - AR - AFK 3% (-35 degree) - AR AF AFFF TXIV NTUJ CEEB TSHEEJ RAUG RAUG. Txhua yam txawv txav nthuav dav zoo li ntshiab daj ntseg daj - kua daj, haum nrog qhov zoo ntawm afil ua npuas dej. Lawv cov qib qib sib txawv ntawm tus qauv: 7.6-7.9 rau hom -3 Qib Degree, thiab 8.5-8.7 rau -35 degree, ua kom muaj kev ruaj ntseg thaum lub sijhawm cia thiab siv.
Cov kev ua tau tseem ceeb ntawm lub A AFFF ua npuas dej kom zoo nkauj suav nrog cov nro ua kom zoo li ntawm 4.0 txog 18 xyoo / m thiab kis cov coeffients ntawm 4.7 txog 18 xyoo Nrog viscosity ntawm tsawg dua los yog sib npaug ntawm 2000 mpas ntawm 20 degree, lub AR Afff ua npuas dej zoo rau kev tua hluav taws. Kev nthuav dav sib npaug (7.1 ± 1 rau 7.5 ± 1) thiab 25% cov sij hawm ntws tawm thiab tiv thaiv kom muaj cawv qhuav - cov xwm txheej hluav taws.
Cov txheej txheem khov Txawm hais tias nyob rau hauv distilleries, tshuaj lom cov nroj tsuag nrog dej cawv - raws li cov kuab tshuaj ua kom zoo nkauj muab, lub neej - Kev Nyab Xeeb Hluav Taws rau cawv rau cawv - Kev phom sij rau dej cawv.

Cov FAQ
Q: Yuav tsis muaj afff ua npuas dej ua kom zoo nrog txhua yam ntawm cov khoom tua hluav taws?
A:Nws tau tshaj nrog feem ntau ua npuas ncauj - cov tshuab sib cais. Tab sis tshuaj xyuas cov cuab yeej cov specs kom ntseeg tau tias nws tuaj yeem ua kom pom cov viscosity (tsawg dua lossis sib npaug nrog 2300 mpas). Qee lub tshuab laus tuaj yeem xav tau kev hloov kho rau kev ua tau zoo nrog qhov kev ua yeeb yam no Aft ua npuas ncauj.
Q: Qhov ntsuas kub tau cuam tshuam li cas rau cov npuas dej nthuav dav ntawm A ARG afff ua npuas dej zoo?
A:Qis dua kub (ze rau qhov txias txias) tuaj yeem txo qis cov kev nthuav dav. Nyob rau hauv cov kev mob txias dua, ua npuas ncauj yuav denser. Kev sim ntawm AR AF AFNT ua kom zoo nkauj rau hauv qhov chaw xa tawm ib puag ncig kom paub meej tias cov kev nthuav dav uas tau raws li koj cov kev xav tau.
Q: Txoj kev ua tau zoo tshaj plaws los muab pov tseg ntawm kev tsis siv Afff ua npuas ncauj mloog zoo?
A:Ua raws li cov kev cai ib puag ncig hauv zos. Hu rau cov kev pabcuam tsis zoo - khib nyiab pov tseg, raws li lub A AR AFFF ua npuas ua kom muaj cov tshuaj uas tsis tuaj yeem muab pov tseg. Tsis txhob tso nws mus rau hauv cov chaw dej los yog av.
Q: Puas yog lub AF AFN a aft ua npuas mam xav tau kev cob qhia tshwj xeeb?
A:Yog lawm. Vim nws cov dej cawv tshwj xeeb - cov mis nyuj tshwj xeeb - cov lus qhia, kev cob qhia kev zam txim, kev sib xyaw ua ke, thiab kev nyab xeeb yog pom zoo. Kev siv tsis raug yuav txo nws cov ua haujlwm tawm tsam cov hluav taws kub, yog li kev nkag siab nws cov khoom tshwj xeeb yog qhov tseem ceeb.
Q: Yuav tsis muaj afff ua npuas dej zoo mloog nrog lwm hom hluav taws - ntaus npawg?
A:Sib tov nrog lwm cov npuas dej tsis yog qhia, raws li nws tuaj yeem cuam tshuam nrog cov cawv - cov khoom tiv thaiv ntawm lub arch aft zoo mloog. Siv nws ua kev daws teeb meem rau kev haus cawv - raws li cov kev pheej hmoo hluav taws rau cov txiaj ntsig zoo tshaj plaws.
