Lub tshuab ua npuas ncauj yog cov khoom siv tua hluav taws uas ua haujlwm los ntawm kev xa cov khoom ua npuas dej rau hauv hluav taws. Cov npuas dej no yog sib xyaw ntawm dej, ua npuas dej ua kom pom tseeb, thiab cua uas tsim ib daim pam uas npog thiab ua kom cov hluav taws kub hnyiab, tshem tawm cov pa oxygen thiab cais nws cov roj los ntawm cov nplaim taws.
Thaum lub tshuab ua npuas ncauj pom qhov hluav taws kub, nws tso cov npuas dej sib xyaw rau hauv ib puag ncig los ntawm kev faib cov kav dej thiab cov nozzles. Cov npuas dej nthuav dav thaum sib cuag nrog huab cua thiab tsim ib txheej tuab, frothy uas npog qhov hluav taws kub thiab suppresses nws.
Muaj ntau hom ua npuas ncauj siv nyob rau hauv ua npuas ncauj chambers, xws li aqueous film-forming foam (AFFF), fluoroprotein ua npuas ncauj (FP), cawv-resistant foam (AR), thiab protein ua npuas ncauj. Txhua hom ua npuas ncauj concentrate muaj cov khoom sib txawv uas ua rau nws haum rau qee hom hluav taws kub.
Foam chambers feem ntau yog siv nyob rau hauv cov chaw muaj kev pheej hmoo siab xws li hangars, warehouses, fuel loading terminals, thiab lwm qhov chaw uas muaj cov nplaim taws los yog cov khoom siv. Lawv muaj txiaj ntsig zoo hauv kev tua hluav taws uas cuam tshuam nrog cov kua dej thiab cov pa hluav taws xob vim tias lawv tuaj yeem tsim ib qho kev thaiv uas cais cov roj los ntawm qhov hluav taws kub.
Ntxiv nrog rau lawv cov peev xwm tua hluav taws, ua npuas ncauj chamber kuj yog ib puag ncig zoo. Cov npuas dej siv nyob rau hauv feem ntau cov npuas dej yog biodegradable thiab tsis ua rau muaj kev hem thawj rau ib puag ncig.
Zuag qhia tag nrho, cov chav ua npuas ncauj yog cov cuab yeej siv hluav taws xob zoo thiab siv tau los tiv thaiv tib neeg, khoom vaj khoom tsev, thiab ib puag ncig. Lawv yog cov cuab yeej pov thawj uas tau cawm ntau lub neej thiab tiv thaiv kev sib kis ntawm hluav taws.
