Hauv kev tsim khoom, kev hloov pauv tau dav siv los ua kom zoo dua cov txheej txheem thiab kev ua haujlwm ntawm cov khoom. Piv txwv li, nyob rau hauv tshuaj lom neeg cov tshuaj tiv thaiv, modifiers yuav tswj lub system cov acidity, alkalinity, ionic zog, los yog cov tshuaj tiv thaiv tus nqi, yog li txhim kho cov khoom purity thiab cov tshuaj tiv thaiv efficiency. Hauv kev tsim cov xim, inks, thiab cov yas, cov khoom siv hloov kho ua haujlwm los txhim kho cov khoom ntws, dispersibility, thiab gloss nto, ua kom muaj kev ruaj ntseg ntau dua ntawm cov khoom thaum ua tiav thiab xaus - siv.
In liquid or foam-based systems, modifiers are frequently utilized to control physical properties such as viscosity, density, surface tension, or foam stability. Piv txwv li, qhov sib ntxiv ntawm cov kev hloov pauv rau cov neeg ua npuas ncauj thiab cov emulsions tuaj yeem ua kom cov npuas ntev ntev, ua kom cov npuas zoo nkauj zoo nkauj, lossis ua kom cov emulsions zoo ib yam thiab ruaj khov. Cov ntawv thov no tshwj xeeb yog qhov tseem ceeb hauv kev tsim cov khoom siv tshuaj txhua hnub, kev ua zaub mov, thiab cov ntxhia flotation.
Modifiers kuj pom daim ntawv thov hauv kev kho ib puag ncig thiab kev tsim cov khoom siv. Piv txwv li, hauv cov txheej txheem kho dej, cov kev hloov kho tuaj yeem kho cov qib pH lossis hlau ion concentrations txhawm rau txhim kho kev ua haujlwm ntawm cov hlau hnyav los nag lossis tshem tawm; nyob rau hauv catalyst los yog adsorbent systems, lawv tuaj yeem txhim kho qhov kev faib tawm ntawm cov khoom siv hluav taws xob lossis txhim kho kev xaiv cov tshuaj tiv thaiv. Los ntawm kev txiav txim siab ntawm kev hloov kho, nws muaj peev xwm ua kom muaj txiaj ntsig zoo ntawm cov txheej txheem kev lag luam thiab kev ua tiav tag nrho ntawm cov khoom tsim.
