Lub luag hauj lwm ntawm dej-raws li dispersants nyob rau hauv painting phab ntsa
Jan 25, 2024
Dej raws li dispersants tuaj yeem siv rau txhua hom dej-raws li txheej. Dej raws li dispersants yuav siv tau los disperse inorganic pigments nyob rau hauv dej-raws li coatings thiab kuj stabilizing txheej. Qhov dej-raws li dispersant no muaj qhov zoo ntawm cov tsis muaj foaming, uas tuaj yeem ua rau muaj qhov tsis xws luag ntawm txheej txheej thiab kev siv defoamers.
Dej raws li dispersants tseem tuaj yeem txo cov viscosity ntawm cov dej-raws li txheej, hloov txoj kev khiav hauj lwm, thiab muaj kev ruaj ntseg zoo ntawm cov viscosity ntawm cov xim latex, uas tuaj yeem zam cov xim los nag. Thaum siv ua ke nrog cov tsis-ionic wetting agents, nws tuaj yeem ua tiav cov nyhuv ntub dej zoo, txhim kho cov nyhuv dispersion, thiab muaj cov yam ntxwv zoo heev.
Cov txheej txheem dej raws li kev xav tau siab rau cov phab ntsa yuav tsum tau pleev xim, thiab yuav tsum ua kom cov phab ntsa huv si. Yog tias cov phab ntsa tsis huv txaus, nws yog ib qho yooj yim uas yuav ua rau shrinkage qhov nyob rau hauv lub txheej. Nws tuaj yeem siv ncaj qha rau cov phab ntsa ntub dej lossis qhov chaw vim tias cov txheej txheem muaj qhov hloov tau zoo rau ib puag ncig thiab tuaj yeem txuas tau zoo rau phab ntsa. Txhuam cov cim feem ntau tuaj yeem pom thaum siv cov xim, uas yog tshwm sim los ntawm cov xim tsis txaus. Kev siv cov dej-raws li dispersants tuaj yeem ua rau cov xim pigment ntau ruaj khov thiab txhim kho qib.
