Hydroxyethyl Cellulose siv hauv Tshuaj pleev ib ce

Hauv cov tshuaj pleev ib ce, muaj ntau yam tsis muaj xim thiab tsw ntxhiab, tab sis ob peb yam tsis muaj tshuaj lom. Hnub no kuv yuav qhia koj txoghydroxyethyl cellulose, uas muaj ntau heev hauv ntau cov tshuaj pleev ib ce lossis khoom siv txhua hnub.

Hydroxyethyl Cellulose

Kuj tseem hu ua (HEC) yog xim dawb los yog lub teeb daj, tsis muaj ntxhiab, tsis muaj kuab lom los yog hmoov hmoov. Vim nws cov khoom zoo ntawm thickening, suspending, dispersing, emulsifying, adhering, film-forming, tiv thaiv ya raws thiab muab kev tiv thaiv colloid, HEC tau siv dav hauv kev kho mob thiab tshuaj pleev ib ce.

Khoom nta

1. HEC yog soluble nyob rau hauv dej kub los yog dej txias, kub kub los yog boiling tsis muaj nag lossis daus, yog li ntawd nws muaj ib tug ntau yam ntawm solubility thiab viscosity yam ntxwv, thiab non-thermal gelation;

2. Nws yog non-ionic thiab tuaj yeem ua ke nrog lwm cov dej-soluble polymers, surfactants thiab ntsev nyob rau hauv ntau yam. Nws yog ib qho zoo heev colloidal thickener rau cov kev daws teeb meem uas muaj high-concentration dielectrics;

3. Lub peev xwm tuav dej yog ob zaug siab dua li ntawm methyl cellulose, thiab nws muaj kev tswj xyuas zoo dua;

4. Piv nrog rau kev lees paub methyl cellulose thiab hydroxypropyl methyl cellulose, lub peev xwm dispersing ntawm HEC yog qhov phem tshaj, tab sis lub peev xwm tiv thaiv colloid yog qhov muaj zog tshaj.

Qhov hnyav molecular hauv cov tshuaj pleev ib ce, qhov ntom ntawm cov khoom xws li cov khoom siv hluavtaws thiab cov khoom siv hluavtaws sib txawv, yog li nws yog ib qho tsim nyog yuav tsum tau ntxiv cov tshuaj solubilizer kom tag nrho cov khoom xyaw ua haujlwm zoo tshaj plaws. Lub solubility thiab viscosity ntawm hydroxyethyl cellulose ua lub luag haujlwm tag nrho, thiab tswj cov yam ntxwv sib luag, kom nws tuaj yeem tswj tau cov khoom qub ntawm cov tshuaj pleev ib ce nyob rau lub caij nyoog ntawm kev sib hloov txias thiab kub. Tsis tas li ntawd, nws muaj cov khoom moisturizing thiab feem ntau pom nyob rau hauv cov tshuaj pleev ib ce rau cov khoom moisturizing. Tshwj xeeb qhov ncauj qhov ntswg, toners, thiab lwm yam yog yuav luag tag nrho ntxiv.

Muaj nuj nqinyhuv

Hydroxyethyl cellulose siv nyob rau hauv cov tshuaj pleev ib ce xws li emollients, thickeners, thiab lwm yam yog yeej tsis muaj tshuaj lom. Thiab nws raug suav tias yog No. 1 ib puag ncig kev nyab xeeb khoom los ntawm EWG.
