Hydroxyethyl cellulose feem ntau siv nyob rau hauv cov tshuaj pleev ib ce

Hauv cov tshuaj pleev ib ce, muaj ntau yam tsis muaj kob thiab tsis muaj ntxhiab tsw qab, tab sis ob peb cov khoom tsis muaj tshuaj lom. Niaj hnub no kuv yuav qhia koj rau hydroxyethyl cellulose, uas muaj ntau heev nyob rau ntau cov tshuaj pleev ib ce lossis cov khoom siv txhua yam.

Hydroxyethyl cellulose
Kuj tseem hu ua (HEC) yog xim dawb lossis lub teeb daj, tsw ntxhiab, tsis muaj kuab lom lossis powdery cov khoom. Vim tias nws cov khoom zoo ntawm thickening, ncua, emulsifying, ua yeeb yaj kiab, HEC tau siv dav hauv kev kho mob thiab kev ua kom zoo nkauj.

Khoom nta
1. HEC yog soluble hauv dej kub lossis dej txias lossis npau npau yam tsis muaj nag dej, yog li nws muaj ntau yam ntawm solubility, thiab tsis-thermal gelation;

2. Nws yog tsis-ionic thiab tuaj yeem uake nrog lwm cov dej-soluble polymers, solfactants thiab ntsev nyob rau hauv ntau yam. Nws yog ib qho zoo tshaj plaws colloidal thickener rau cov kev daws teeb meem muaj cov siab-siab cov dielessrics;

3

4. Piv nrog lees paub methyl cellulose thiab hydroxypropal methylropy, lub dispersing muaj peev xwm ntawm hac yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv kev muaj peev xwm yog qhov muaj zog tshaj.

Lub luag haujlwm hauv Tshuaj pleev ib ce
Qhov hnyav molecular hauv tshuaj pleev ib ce, qhov ceev ntawm cov ntsiab lus xws li cov khoom siv hluavtaws thiab khoom siv hluav taws xob sib txawv, yog li nws yog ib qho tsim nyog los ntxiv rau tag nrho cov khoom xyaw ua haujlwm zoo tshaj plaws. Lub solubility thiab viscosity cov khoom ntawm hydroxyethyl cellulose tag nrho ua lub luag haujlwm, kom nws tuaj yeem tswj hwm cov tshuaj pleev ib ce qub nyob rau lub caij nyoog ntawm lwm tus txias thiab kub. Tsis tas li ntawd, nws muaj cov dej noo thiab feem ntau pom hauv cov tshuaj pleev ib ce rau cov khoom siv noo noo. Qhov tshwj xeeb ntawm lub qhov ncauj qhov ncauj, toners, thiab lwm yam yuav luag txhua ntxiv.

Sab cuam
Hydroxyethyl cellulose siv hauv cov tshuaj pleev ib ce xws li empollients, thickeners, thiab lwm yam yog tsis muaj tshuaj lom. Thiab nws suav hais tias yog tsis muaj. 1 ib puag ncig cov khoom muaj kev nyab xeeb ntawm EWM.
