Cov nyhuv ntawm dispersants ntawm cov xim

Dispersant yog ib qho khoom siv feem ntau siv rau hauv toner, uas yuav pab kom ntub cov xim, txo qhov me me ntawm cov xim, thiab ua rau kom muaj kev sib raug zoo ntawm cov resin thiab cov xim, yog li txhim kho kev sib raug zoo ntawm cov xim thiab cov cab kuj, thiab txhim kho. dispersion ntawm cov xim.Qib.Nyob rau hauv cov txheej txheem ntawm cov xim txuam, ntau hom dispersants yuav cuam tshuam cov xim zoo ntawm cov khoom.

Lub melting point ntawm cov dispersant feem ntau qis dua qhov kub ntawm cov resin, thiab thaum lub sij hawm molding txheej txheem, nws melts ua ntej resin, yog li ua kom lub fluidity ntawm cov resin.Thiab vim hais tias cov dispersant muaj tsawg viscosity thiab zoo compatibility nrog pigments, nws muaj peev xwm nkag mus rau hauv lub pigment agglomerate, hloov lwm shear quab yuam los qhib lub pigment agglomerate, thiab tau ib tug uniform dispersion nyhuv.
Txawm li cas los xij, yog tias qhov hnyav molecular ntawm cov dispersant tsawg dhau thiab cov ntsiab lus melting tsawg dhau, qhov viscosity ntawm lub kaw lus yuav raug txo kom tsawg, thiab sab nraud shear quab yuam hloov los ntawm cov qauv mus rau cov xim agglomerates kuj yuav txo tau zoo heev, ua. Nws nyuaj rau qhib cov agglomerated hais thiab cov pigment hais tsis tuaj yeem raug dispersed zoo.Hauv cov yaj, cov xim zoo ntawm cov khoom yog qhov kawg tsis txaus siab.Thaum siv cov dispersants nyob rau hauv cov txheej txheem xim sib xws, tsis xws li cov txheeb ze molecular hnyav thiab melting point yuav tsum tau txiav txim siab, thiab dispersants haum rau pigments thiab carrier resins yuav tsum tau xaiv.Tsis tas li ntawd, yog tias tus nqi ntawm cov dispersant loj heev, nws tseem yuav ua rau cov xim ntawm cov khoom tig daj thiab ua rau chromatic aberration.
