Tom qab ntxiv cov tshuaj ua npuas rau hauv cov tshuaj tua kab mob thiab siv rab phom ua npuas tshwj xeeb los tua kab mob, qhov chaw ntub dej yuav tsim ib txheej "dawb" pom tom qab tua kab mob, qhia meej meej txog thaj chaw uas tau txau cov tshuaj tua kab mob. Txoj kev tua kab mob ua npuas no tau txais thiab siv los ntawm ntau lub teb.
Cov khoom tseem ceeb ntawm cov tshuaj ua npuas ncauj yog ib qho surfactant, ib yam khoom tseem ceeb hauv cov tshuaj zoo, feem ntau hu ua "MSG kev lag luam." Surfactants yog cov tshuaj uas tuaj yeem txo qhov nro ntawm qhov chaw ntawm cov tshuaj. Lawv muaj cov pab pawg hydrophilic thiab lipophilic ruaj khov thiab tuaj yeem sib phim ntawm qhov chaw ntawm cov tshuaj. Los ntawm kev nqus ntawm qhov sib tshuam ntawm cov roj thiab cov kua, lawv txo qhov nro ntawm qhov chaw ntawm dej. Lawv kuj tseem tuaj yeem txo qhov nro ntawm cov roj thiab dej los ntawm kev nqus ntawm qhov sib tshuam ntawm cov kua-kua. Nrog ntau yam kev siv thiab ntau yam kev ua haujlwm, surfactants muaj peev xwm xws li solubilization, thickening, emulsification, wetting, foaming/defoaming, ntxuav thiab decontamination, dispersion, sterilization thiab disinfection, antistatic effects, softening, thiab smoothing.
Kev ua npuas dej yog ib qho ntawm cov haujlwm tseem ceeb ntawm cov surfactants. Cov surfactants ua npuas dej tuaj yeem txo qhov nro ntawm qhov chaw ntawm dej thiab teeb tsa ua ob txheej hluav taws xob ntawm qhov chaw ntawm cov kua dej kom ntes cua, tsim cov npuas dej. Cov npuas dej no ces sib xyaw ua ke los ua npuas dej. Cov neeg sawv cev ua npuas dej zoo qhia txog lub zog ua npuas dej muaj zog, cov qauv ua npuas dej zoo, thiab kev ruaj khov ua npuas dej zoo heev.
Peb yam tseem ceeb rau kev tua kab mob zoo yog: kev tua kab mob zoo, kev siv tshuaj kom raug, thiab lub sijhawm sib cuag txaus. Thaum ua kom ntseeg tau tias cov tshuaj tua kab mob zoo, kev siv cov tshuaj tua kab mob uas muaj cov tshuaj ua npuas thiab siv rab phom ua npuas tshwj xeeb ua rau lub sijhawm sib cuag ntawm cov tshuaj tua kab mob thiab qhov chaw ntawm lub hom phiaj nrog rau cov kab mob pathogenic, yog li ua tiav kev tua kab mob zoo dua thiab ua tiav.
