Hydroxyethyl cellulose yog dab tsi?

Hydroxyethyl cellulose (HEC) yog ib qho hluavtaws polymer muab los ntawm cellulose, ib txwm tshwm sim polysaccharide pom hauv cov nroj tsuag. Nws yog cov hmoov dawb, dej-soluble hmoov uas yog siv los ua cov thickening, suspending, thiab stabilizing tus neeg sawv cev nyob rau hauv ntau yam khoom, xws li tshuaj pleev ib ce, tshuaj, tshuaj detergents, thiab khoom noj khoom haus.

HEC yog tsim los ntawm reacting cellulose nrog ethylene oxide, ib tug tshuaj compound muab los ntawm ethylene, ib tug hydrocarbon gas. Cov ethylene oxide reacts nrog hydroxyl pawg ntawm cellulose molecules, tsim ether kev sib txuas ntawm cellulose molecules. Cov tshuaj tiv thaiv no tsim cov polymer nrog lub cev hnyav dua li qub cellulose, thiab muab cov polymer nws cov dej-soluble zog.

HEC yog siv rau hauv ntau yam khoom, xws li tshuaj pleev ib ce, tshuaj, tshuaj ntxuav tes, thiab khoom noj khoom haus. Nyob rau hauv cov tshuaj pleev ib ce, nws yog siv raws li ib tug thickening neeg sawv cev, suspending agent, thiab stabilizer. Hauv kev lag luam tshuaj, nws yog siv los ua ib qho binder, disintegrant, thiab suspending agent. Nyob rau hauv cov tshuaj detergents, nws yog siv los ua ib tug thickening neeg sawv cev, suspending agent, thiab stabilizer. Hauv cov khoom noj khoom haus, nws yog siv los ua tus neeg sawv cev thickening, suspending agent, thiab stabilizer.

HEC kuj tseem siv rau hauv cov roj thiab roj drilling kev ua haujlwm, qhov twg nws yog siv los ua kom cov viscosity ntawm cov dej drilling thiab txo cov kua dej los ntawm kev tsim. Nws kuj yog siv rau hauv papermaking, qhov twg nws yog siv los ua kom muaj zog thiab nruj ntawm daim ntawv.

HEC yog cov khoom tsis muaj tshuaj lom, tsis ua rau khaus, thiab tsis ua xua, ua rau nws muaj kev nyab xeeb rau kev siv ntau yam khoom. Nws tseem yog biodegradable, ua rau nws xaiv ib puag ncig tus phooj ywg.
