Yog lawm, hydroxyethyl cellulose (HEC) yog hydrophilic, uas txhais tau hais tias nws muaj affinity rau dej thiab soluble hauv dej.HEC yog cov dej-soluble polymer uas tau los ntawm cellulose, ib txwm tshwm sim polymer pom nyob rau hauv cov nroj tsuag.Cov pab pawg hydroxyethyl ntawm HEC molecule nce nws cov dej solubility los ntawm kev qhia cov pab pawg hydrophilic (dej-hlub) mus rau hauv cov pob txha cellulose.
HEC feem ntau yog siv nyob rau hauv ntau yam kev lag luam ua cov thickener, binder, thiab stabilizer vim nws cov dej-solubility zoo heev thiab muaj peev xwm los tsim cov kev daws teeb meem ruaj khov.HEC yog siv rau hauv cov khoom siv tu tus kheej xws li cov tshuaj zawv plaub hau thiab tshuaj pleev ib ce ua cov thickener thiab emulsifier, nrog rau cov xim pleev xim thiab txheej txheej raws li kev sib khi thiab kev hloov kho rheology.
Zuag qhia tag nrho, HEC yog hydrophilic polymer uas yog soluble hauv dej thiab tuaj yeem tsim cov kev daws teeb meem ruaj khov.Nws cov dej-solubility ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov uas dej yog qhov tseem ceeb.
