Dispersants yog cov khoom tseem ceeb hauv cov xim thiab cov xim. Lawv lub luag haujlwm tseem ceeb yog kom sib npaug thiab ruaj khov disperse pigments thiab fillers hauv resins thiab cov kuab tshuaj, tiv thaiv agglomeration thiab teeb meem. Cias muab, lawv ua rau cov xim zoo ib yam, ci dua thiab ruaj khov.
Lub luag haujlwm tseem ceeb
Tiv thaiv pigment agglomeration thiab flocculation
Pigment particles zoo li clump ua ke. Dispersants adsorb rau cov xim xim, cais cov khoom thiab txwv tsis pub lawv rov ua dua.
Txo kev sib tsoo nyuaj thiab txo lub sij hawm dispersion
Tsawg viscosity, yooj yim sib tsoo, txhim kho kev tsim khoom thiab txo kev siv hluav taws xob.
Txhim kho zaj duab xis tsos thiab xim ua haujlwm
Zoo dispersion txhim khu lub zog tinting, zais lub zog thiab gloss
Cov xim yog purer thiab zoo ib yam, tsis muaj dej nyab los yog ntab
Txhim khu kev ruaj ntseg cia
Tiv thaiv cov xim tawv nqaij thiab tawv tawv, ua kom cov xim nyob ruaj khov, tsis muaj kev sib cais los yog caking thaum lub sij hawm ntev cia.
Txhim kho daim ntawv thov thiab qib
Txo cov viscosity thiab txhim kho ntws, ua rau kom zoo dua qib thiab tsawg txhuam cov cim.
Cov ntsiab lus
Dispersants ua raws li "dispersion & stabilization kws txawj" nyob rau hauv cov xim: lawv zom cov pigments finely, faib lawv tusyees, thiab tswj stability, ncaj qha txiav txim xim, gloss thiab stability ntawm qhuav zaj duab xis.
