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 cov hmoov dawb, tsis muaj ntxhiab, tsis qab, uas yog siv rau ntau yam kev lag luam, suav nrog zaub mov, tshuaj, tshuaj pleev ib ce, thiab ntawv.HEC yog siv los ua tus neeg sawv cev thickening, emulsifier, stabilizer, thiab suspending agent, thiab siv ntau yam khoom xws li tshuaj zawv plaub hau, tshuaj pleev ib ce, cream, gels, thiab pastes.

HEC yog non-ionic, dej-soluble polymer uas yog tsim los ntawm reacting cellulose nrog ethylene oxide.Nws yog polysaccharide, txhais tau tias nws muaj ntau cov piam thaj molecules txuas ua ke.HEC yog ib yam khoom siv hydrophilic, txhais tau tias nws nyiam dej.Nws tseem yog polyelectrolyte, txhais tau hais tias nws muaj ob qho tib si zoo thiab tsis zoo.Qhov no tso cai rau nws tsim cov ntawv cog lus muaj zog nrog rau lwm cov molecules, ua rau nws ua haujlwm zoo thickening.

HEC yog cov khoom siv ntau yam nrog ntau daim ntawv thov.Nws yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li ib tug thickening tus neeg sawv cev, stabilizer, thiab suspending agent.Nws yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug emulsifier, stabilizer, thiab suspending agent.Nws kuj yog siv nyob rau hauv cov tshuaj pleev ib ce kev lag luam raws li ib tug thickening neeg sawv cev, emulsifier, thiab stabilizer.

HEC yog cov khoom siv muaj kev nyab xeeb thiab siv tau zoo uas siv rau ntau yam kev lag luam.Nws tsis muaj tshuaj lom thiab tsis ua rau khaus, ua rau nws muaj kev nyab xeeb rau kev siv khoom noj, tshuaj, thiab tshuaj pleev ib ce.Nws tseem yog biodegradable, ua rau nws ib puag ncig tus phooj ywg khoom.HEC yog cov khoom siv thickening zoo, emulsifier, thiab stabilizer, ua rau nws muaj ntau yam khoom siv nrog ntau daim ntawv thov.
