Kev siv hluav taws kub ua npuas ncauj concentratenyob rau hauv qis, nruab nrab thiab siab expansion:
1. Dab tsi yog foam concentrate:
Daim pam ua npuas ncauj muaj cov tshuaj tua hluav taws ua npuas ncauj thiab dej (premix tov) ua ke nrog huab cua.
Qhov sib piv nthuav dav yog qhov ntim ntawm cov ua npuas ncauj ua tiav ua piv rau qhov ntim ntawm cov tshuaj premix muab. Cov huab cua ntau tshaj tawm, qhov nthuav dav dua koj tau txais. Piv txwv li: thaum lub tshuab hluav taws xob ua npuas dej muab nrog 100 litres dej + ua npuas dej ua 1000 litres ntawm npuas, qhov kev nthuav dav yog li 1000 / 100=10. Muaj 3 qhov kev nthuav dav nyob ntawm qhov ua npuas ncauj proportioning thiab tso tawm cov khoom siv.
2. Tsawg expansion ua npuas ncauj:
Ua npuas ncauj expansion ratio<20
Kev nthuav dav tsawg feem ntau yog siv dav dav hauv hluav taws xob hydrocarbon xws li hauv lub tank cia, refineries, tshav dav hlau thiab onbroad ships. Lub zog ua npuas dej siab tso cai rau kev nthuav dav ntev thiab qhov siab siv tsau / txawb nozzles lossis saib xyuas kev nyab xeeb los ntawm kev deb. Cov npuas yog me me, ntom thiab hnyav. Daim pam ua npuas ncauj ruaj khov thiab muab lub hau muaj zog. Tsawg expansion ua npuas ncauj muaj ib tug zoo flowability. Nws kis tau sai heev saum cov roj thiab ua raws li qhov chaw ntsug. Nws cais cov roj ntawm cov pa oxygen los ntawm kev tsim cov aqueous lossis polymer zaj duab xis. Ntxiv mus, nws qhov sib piv siab ntawm cov dej tau lees tias qhov ua kom txias txias. Low Expansion npuas tsis rhiab rau atmospheric tej yam kev mob xws li cua los nag.
3.Medium expansion ua npuas ncauj:
Foam expansion ratio Ntau tshaj los yog sib npaug rau 20 txog <200
Kev nthuav dav nruab nrab feem ntau yog siv los ntawm cov chaw tua hluav taws hauv nroog, rau cov chaw me me xws li kev tsheb sib tsoo, cov kuab tshuaj khaws cia lossis tswj cov tshuaj lom neeg txaus ntshai. Ib tug loj npaum li cas ntawm tiav lawm ua npuas ncauj yog tsim nrog tsawg kawg nkaus kom muaj nuj nqis ntawm premix tov thiab nyob rau hauv ib tug luv luv lub sij hawm. Daim pam tuab ua npuas ncauj nrawm nrawm dua cov roj, cais cov roj ntawm cov pa oxygen thiab ua rau hluav taws tua hluav taws. Cov dej uas muaj cov dej txias ntxiv kom tswj tau hluav taws sai dua thiab tiv thaiv kev kav. Tsawg ceev ua rau nws yooj yim rau cua thiab huab cua phem.
4.High expansion ua npuas ncauj:
Expansion ratio ntawm npuas ntau dua los yog sib npaug rau 200
High Expansion feem ntau yog siv rau cov khoom qhuav hluav taws kub lossis cov cheeb tsam uas nyob ib puag ncig los kos cov khoom ntim loj thiab sau cov kab noj hniav xws li warehouse, cellars, aircraft hangar lossis cav / twj tso kua mis chav nyob hauv nkoj. Kev siv dej tsawg dua ua npuas dej ntau heev hauv lub sijhawm luv luv, ua rau hluav taws tua hluav taws los ntawm smothering. Nyob rau hauv siab expansion, npuas yog heev lub teeb thiab loj, lawv muaj ib tug siab feem ntawm huab cua. Ua npuas ncauj yog ua tiav los ntawm kev txau cov tshuaj rau ntawm lub vijtsam dav thaum muaj huab cua ntau yog nkag los lossis raug yuam. High expansion foam tsis haum rau siv sab nraum zoov. High expansion foam fire extinguishing systems yuav tsum tau muab tso rau hauv qhov chaw tam sim ntawm qhov hluav taws kub.
Kev nthuav dav yog ze ze rau hom ua npuas ncauj concentrate thiab cov khoom siv ua npuas dej siv. FOREDE Synthetic firefighting foam concentrates yog haum rau Tsawg, Nruab Nrab thiab Siab Tshaj.
