Foam extinguishing tus neeg saib xyuas yuav raug muab tso rau hauv cov tshuaj ua kua tshuaj tua hluav taws thiab cov pa hluav taws kub extinguishing tus neeg saib xyuas. Tshuaj lom neeg npuas yog tsim los ntawm kev tshuaj lom neeg los ntawm kev daws cov ntxhuav ntawm txhuas sulfate thiab sodium carbonate, thiab cov roj hauv cov kua roj carbon dioxide. Cov pa npuas yog tsim los ntawm kev sib tov nrog kev sib tov ntawm cov huab cua ua kua pa hluav taws thiab cua nyob hauv npuas hluav taws xob, yog li cov cua npuas yog hu ua tus neeg ua haujlwm tshuab foam, thiab cov roj ua muaj nyob hauv npuas huab cua.
Cua ua npuas ncauj tua hluav taws extinguishing tus neeg ntau yam, raws li foam multiples, yuav muab faib ua pes tsawg tus npuas, nruab nrab ntau npuas npau thiab ntau tus npaus npuas peb pawg. Cov foaming multiples ntawm tus neeg ua haujlwm qis hluav taws xob feem ntau yog qis dua 20 zaug, feem ntau tus neeg ua haujlwm rau tus neeg sawv cev feem ntau yog 20 ~ 200 zaug, cov foaming multiplex ntawm cov hluav taws xob tua hluav taws xob feem ntau yog hauv 201 ~ 1000 sij hawm.
Raws li hom thiab siv foaming tus neeg sawv cev, cov ua pa loj ua pa taws ua rau hluav taws tua hluav taws yog muab faib ua protein ntau, fluorine protein ua npuas, dej ua txoj kab ua kua, hluavtaws hluavtaws, dej ntau hom. Medium thiab high-number foam extinguishing tus neeg muag khoom belongs rau hom hluavtaws ua hluavtaws.
