HEC khoom yog dab tsi?

HEC (Hydroxyethyl Cellulose) yog ib qho hluavtaws polymer muab tau los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag. Nws yog non-ionic, dej-soluble polymer siv nyob rau hauv ntau yam kev siv, nrog rau cov khoom siv tu tus kheej, tshuaj, khoom noj khoom haus, thiab kev siv hauv kev lag luam. HEC yog cov khoom siv ntau yam uas muaj ntau yam khoom, suav nrog cov thickening, stabilizing, ncua, thiab emulsifying.

HEC yog tsim los ntawm cov txheej txheem hu ua etherification, uas cellulose yog kho nrog ethylene oxide los ua ib tug polyether. Cov khoom uas tau tshwm sim yog polyether-based polymer nrog ntau yam khoom, suav nrog thickening, suspending, thiab emulsifying. HEC yog cov hmoov dawb, tsis muaj ntxhiab, thiab tsw qab uas yog soluble hauv dej thiab lwm cov kuab tshuaj polar.

HEC yog siv rau ntau yam kev siv, suav nrog cov khoom tu tus kheej, tshuaj, khoom noj khoom haus, thiab daim ntawv thov kev lag luam. Hauv cov khoom tu tus kheej, HEC yog siv los ua cov thickener, stabilizer, thiab emulsifier. Nws yog siv los ua cov tshuaj zawv plaub hau, tshuaj kho mob, tshuaj pleev, thiab tshuaj pleev, ntxiv rau kom ruaj khov thiab emulsify cov roj thiab dej sib tov. Hauv kev lag luam tshuaj, HEC yog siv los ua tus neeg sawv cev ncua, nrog rau cov stabilizer thiab thickener. Hauv cov khoom noj khoom haus, HEC yog siv los ua cov stabilizer, thickener, thiab emulsifier. Nws yog siv los ua kua ntses, gravy, thiab kua zaub, ntxiv rau kom ruaj khov thiab emulsify cov roj thiab dej.

Hauv cov ntawv thov kev lag luam, HEC yog siv los ua cov thickener, stabilizer, thiab emulsifier. Nws yog siv los thicken xim, coatings, thiab adhesives, nrog rau kom stabilize thiab emulsify sib tov ntawm roj thiab dej. HEC kuj tseem siv rau hauv cov roj thiab roj drilling thiab tsim khoom, ua tus hloov kho viscosity, thiab ua tus neeg sawv cev gelling.

HEC yog cov khoom siv ntau yam nrog ntau yam khoom, ua rau nws haum rau ntau yam kev siv. Nws yog non-ionic, dej-soluble polymer uas yog siv los ua kom tuab, ruaj khov, thiab emulsify sib tov ntawm cov roj thiab dej. Nws yog siv rau hauv cov khoom tu tus kheej, tshuaj, khoom noj khoom haus, thiab kev siv hauv kev lag luam. HEC yog cov khoom siv muaj kev nyab xeeb thiab siv tau zoo uas siv ntau yam kev siv.
