Dispersants yog Additives uas tuaj yeem txhim kho thiab txhim kho qhov kev ua tau zoo ntawm cov khoom ua kua los yog kua

Dispersants yog cov khoom siv ntxiv uas tuaj yeem txhim kho thiab txhim kho kev ua haujlwm ntawm cov khoom siv los yog kua. Thaum sib tsoo cov khoom dyes, ntxiv cov dispersant pab txhawm rau zom cov khoom thiab tiv thaiv kev sib sau ntawm cov khoom uas twb tau tawg lawm thaum tswj kev ruaj ntseg ntawm cov dispersion. Cov roj raws li cov kua dej uas tsis muaj dej nyob hauv dej tuaj yeem tawg mus rau hauv cov me me hauv qab siab shear stirring. Tom qab nres stirring, lawv sai sai txheej nyob rau hauv qhov kev txiav txim ntawm interfacial nro. Tom qab ntxiv cov dispersants thiab nplawm, qhov ruaj khov emulsion tuaj yeem tsim. Nws lub luag haujlwm tseem ceeb yog txhawm rau txo qhov kev sib tshuam ntawm cov kua thiab cov kua ua kua. Yog li ntawd, dispersants kuj yog surfactants. Cov hom muaj xws li anionic, cationic, non-ionic, amphoteric, thiab polymer hom. Hom anionic feem ntau yog siv.
