Lye ntxuav
Ib txoj kev tu raws li cov tshuaj lom neeg ntawm alkali, Tianjin seamless square tube chaw tsim tshuaj paus, vim nws siv tau yooj yim, Tianjin seamless square raj, tus nqi qis, yooj yim kom tau cov ntaub ntawv raw, yog dav siv. Txij li thaum cov txheej txheem ntxuav alkaline cia siab rau ntau yam teebmeem xws li saponification thiab emulsification, ib qho alkali tsis tuaj yeem siv los ua kom tiav cov haujlwm saum toj no. Feem ntau siv ntau yam khoom siv, thiab qee zaum ntxiv cov khoom ntxiv xws li surfactants ntxiv. Qib ntawm alkalinity txiav txim siab qhov twg ntawm cov tshuaj tiv thaiv saponification, thiab alkalinity siab tuaj yeem txo qhov nro ntawm cov roj thiab cov tshuaj, ua rau cov roj stain yooj yim rau emulsify. Tsis tas li ntawd, tus neeg saib xyuas kev tu rau ntawm qhov chaw ntawm lub raj duab plaub tuaj yeem raug tshem tawm los ntawm kev ntxuav nrog dej tom qab ntxuav alkaline.
Surfactant ntxuav
Nws yog ib txoj hauv kev siv degreasing los ntawm kev siv cov yam ntxwv ntawm cov surfactants xws li tsis tshua muaj qhov nro, nkag mus zoo thiab ntub dej, thiab muaj peev xwm emulsification muaj zog. Los ntawm cov emulsification ntawm surfactants, ib tug interface zaj duab xis nrog ib tug tej lub zog yog tsim nyob rau hauv cov roj-dej interface, uas hloov lub xeev ntawm lub interface, thiaj li hais tias cov roj stains yog dispersed nyob rau hauv lub aqueous tov los tsim ib tug emulsion. Los yog los ntawm cov nyhuv dissolving ntawm cov surfactant, cov dej-insoluble roj nyob rau hauv lub raj raj tuaj yeem yaj nyob rau hauv cov surfactant micelles kom ua tiav lub hom phiaj ntawm kev xa cov roj mus rau cov tshuaj aqueous.
