Tus txheej txheem ua haujlwm ntawm dispersant tsuas yog suav nrog cov hauv qab no:
Adsorption: Dispersants tsim cov adsorption ntawm cov khoom muaj khoom hauv lawv cov qauv molecular thiab tshuaj lom neeg, txhim kho qhov tsis muaj zog ntawm cov khoom no. Thaum polymer dispersants yog adsorbed ntawm cov khoom siv, ib qho kev kos duab kos rau saum npoo av, tab sis kuj tseem cuam tshuam txog cov khoom sib txuam.
Ob chav txheej txheej txheej txheem: hauv cov txheej txheej hauv dej, cov ntawv tsis sib xws yog xaiv tau cov adsorbed ntawm hmoov thiab dej los ua ib txheej txheej txheej txheej. Anionic Dispersants yog ionized nyob rau hauv dej los ua anions, uas yog adsorbed rau saum npoo ntawm hmoov. Tom qab cov dispersant yog adsorbed nyob rau saum npoo ntawm hmoov hmoov, cov itions yog nruj nreem adsorbed nyob rau saum npoo ntawm cov lus thiab raug hu ua lub ntsej muag ions; Cov kabmob ions nrog cov nqi rov qab nyob rau hauv nruab nrab yog hu ua nruab nrab yog hu ua kev sib tw, uas muab sib txuas nrog cov npoo ions los ntawm electrostatic kev txiav txim. Nyob rau hauv txoj kev no, ib txheej ob chav ob raug tsim ntawm cov npoo ions thiab kev sib cav, thiab cov lus yog tiv thaiv los ntawm kev sib sau ua ke los ntawm electrostatic repulsion.
Kev yuam kev uas siv hluav taws xob nyhuv: dispersant molecules muaj cov cheeb tsam hydrophilic thiab hydrophobic thaj chaw. Lub Micelle qauv lawv lawv daim ntawv nyob hauv cov kuab tshuaj tuaj yeem qhwv khoom thiab tsim cov txiaj ntsig tsis sib haum, yog li cov lus kom muaj qee yam kev deb. Sticer Bind Cov nyhuv: Lub Micelle cov qauv tsim los ntawm dispersant molecules hauv cov kuab tshuaj thiab kev sib sau ua ke ntawm lub xeev dispersed ntawm cov hais. Cov nyhuv them nqi: qee qhov tsis txaus ntseeg tau them rau lawv cov chaw, uas tuaj yeem hloov kho cov hluav taws xob rov qab los tiv thaiv kev sib cais.
