2. Kev xaiv kev txhim kho kev ua tau zoo
Cellulose ether HE series, uas yog, hydroxyethyl cellulose, yog cov hmoov dawb rau mis nyuj dawb. Nws tuaj yeem yaj hauv dej kub thiab dej txias, tab sis nws tsis yooj yim rau yaj hauv cov kuab tshuaj organic. Jinshi hom cellulose ether HE series cov khoom lag luam muaj cov dej tuav ruaj khov, kev tsim cov yeeb yaj kiab, ntsev tsis kam thiab cov nyhuv thickening. Nws kuj muaj cov xim zoo sib xws thiab yog ib qho zoo tshaj plaws additive nyob rau hauv daim ntawv thov latex.
Hydroxyethyl cellulose HEC yog ib qho uas nquag siv cov thickener hauv txheej thiab muaj cov hauv qab no zoo:
(1) Muaj zog versatility Hydroxyethyl cellulose HEC yog ib tug non-ionic dej-soluble polymer uas yuav siv tau nyob rau hauv ib tug dav pH ntau yam (2-12). Nws tuaj yeem sib xyaw nrog cov khoom hauv cov txheej txheem dav dav (xws li pigments, additives, soluble salts thiab electrolytes) yam tsis muaj qhov txawv txav. tus
(2) Kev tsim kho zoo. Cov txheej tuab tuab nrog hydroxyethyl cellulose HEC muaj pseudoplasticity, yog li nws tuaj yeem siv tau los ntawm txhuam, txau, cov menyuam txheej thiab lwm yam kev tsim kho. Qhov zoo, leveling kuj zoo dua. tus
(3) Tsis muaj kev cuam tshuam tsis zoo rau cov yeeb yaj kiab txheej. Vim tias qhov tsis pom tseeb ntawm cov dej tsis sib haum xeeb ntawm HEC aqueous tov, nws tsis yooj yim rau ua npuas ncauj thaum siv thiab tsim khoom, thiab tsis tshua muaj kev nyiam ua cov qhov hluav taws xob thiab cov pinholes. tus
(4) Kev tsim kho xim zoo. Hydroxyethyl cellulose HEC muaj cov miscibility zoo heev nrog feem ntau cov binders thiab colorants, kom cov xim npaj muaj xim zoo thiab sib xws.
(5) Kev ruaj ntseg zoo. Thaum lub sij hawm cia ntawm cov xim, nws muaj peev xwm tswj tau qhov ncua kev kawm ntawv thiab dispersibility ntawm cov xim, tsis muaj teeb meem ntawm floating thiab blooming. Muaj tsawg txheej txheej dej ntawm qhov chaw ntawm cov xim. Thaum lub ntsuas kub hloov pauv, nws cov viscosity tseem zoo li qub. ruaj khov dua.
