Lub luag haujlwm tseem ceeb ntawm hydroxyethyl cellulose hauv cov tshuaj pleev ib ce thiab cov tshuaj tu tawv nqaij yog cov neeg sawv cev ua yeeb yaj kiab, cov khoom nplaum, thiab cov duab txias. Qhov kev pheej hmoo yog 1, uas muaj kev nyab xeeb thiab tuaj yeem siv nrog kev ntseeg siab. Feem ntau, nws tsis muaj qhov cuam tshuam rau cov poj niam cev xeeb tub. Hydroxyethyl cellulose tsis yog comedogenic. Hydroxyethyl cellulose yog hluavtaws cov tshuaj nplaum polymer cov kua nplaum uas yog siv los ua cov tawv nqaij txias, zaj duab xis yav tas los thiab antioxidant hauv tshuaj pleev ib ce.
Muaj ntau cov khoom xyaw hauv cov tshuaj pleev ib ce, thiab txhua tus tsis paub tias lub luag haujlwm ntawm cov khoom xyaw no yog dab tsi?
Lub luag haujlwm ntawm hydroxyethyl cellulose hauv tshuaj pleev ib ce:
Lub solubility thiab viscosity tej yam ntawm hydroxyethyl cellulose ua tiav cov tshuaj pleev ib ce tag nrho tuaj yeem tswj hwm 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.
Cov tshuaj pleev ib ce tuaj yeem muab cia rau hauv tub yees?
Qee cov tshuaj pleev ib txhia tuaj yeem khaws cia rau hauv tub yees, xws li kua tshuaj pleev ib ce, thiab qee cov tshuaj pleev ib ce tsis haum rau hauv tub yees, xws li hmoov tshuaj pleev ib ce lossis cov tshuaj pleev ib ce.
Hmoov tshuaj pleev ib ce suav nrog hmoov, blush thiab qhov muag duab ntxoov ntxoo. Thaum khaws cov tshuaj pleev ib ce no, ua kom cov tshuaj pleev ib ce qhuav, vim tias cov tshuaj pleev ib ce no tsis muaj noo noo thiab tuaj yeem nqus dej noo hauv lub tub yees, uas yuav ua rau cov tshuaj pleev ib ce, uas yuav ua rau cov tshuaj pleev ib ce. Khaws cov tshuaj pleev ib ce hmoov ntawm lub sijhawm zoo tib yam, thiab khaws cia ncaj qha rau hauv qhov chaw txias, qhuav thiab muaj qhov cua.
Yog tias cov khoom lag luam yog cov roj-based, nws kuj tuaj yeem ua rau muaj qhov kub thiab txias, yog li nws tau khaws cia, tsuav nws khaws cia ntawm chav tsev kub.
Cov naj hoom tuaj yeem muab khaws cia rau hauv ib puag ncig kub tsawg, uas tuaj yeem nce txee lub neej. Tshwj xeeb tshaj yog nyob rau lub caij ntuj sov, khaws cia rau hauv lub tub yees yuav ua rau cov naj hoom zoo thiab xis nyob thaum txau.
Qee lub tshuaj pleev ib txhia yog ua los ntawm cov organic lossis khaws cia cov khoom xyaw dawb, thiab khaws cia rau hauv lub tub yees tuaj yeem txuas lub txee rau lub neej thiab ua kom cov tshuaj pleev ib ce tshiab.
Cov nyhuv ntawm hydroxyethyl cellulose rau ntawm daim tawv nqaij:
Hydroxyethyl cellulose tsis muaj qhov cuam tshuam rau ntawm daim tawv nqaij. Hydroxyethyl cellulose yog siv nyob rau ntau lub ntsej muag ntsej muag, thiab tshuaj ntxuav ntsej muag, feem ntau yog vim tias hydroxyethyl cellulose muaj cov flyener thiab emulsifier thiab emulsifier. Hydroxyethyl cellulose yog cov dej-raws li cov khoom lag luam ib puag ncig. Daim tawv nqaij tsis zoo.
Hydroxyethyl cellulose (HEC) yog xim daj lossis lub teeb tsis zoo, cov tshuaj tsw qab, uas tau npaj los ntawm kev tawm tsam ntawm lub ntsej muag ntawm cov tshuaj tsw qab ntawm alkaline (lossis cov tshuaj ethylene eporohydin). Noism soluble cellulose neeg hais txog. Txij li thaum HEC muaj cov yam ntxwv zoo ntawm thickening, kev tshaj tawm, kev tiv thaiv, kev tsim kho, kev tsim kho, kev tsim kho, kev tsim kho, kev tsim kho, kev tsim kho thiab polymer polymnerization thiab lwm thaj teb.
Hauv cov tshuaj pleev ib ce, cov solubility thiab viscosity cov khoom ntawm hydroxyethyl cellulose ua si tag nrho cov kev ua kom zoo nkauj ua si tau tag nrho, thiab tias cov tshuaj pleev ib ce muaj peev xwm ua kom lub cev muaj zog tuaj yeem tswj hwm nyob rau lub caij nyoog ntawm lwm tus txias thiab kub.
Hydroxyethyl cellulose khoom lag luam:
1.C yog soluble hauv dej kub lossis dej txias, thiab tsis precipitate ntawm qhov kub lossis rhaub, kom nws muaj ntau yam ntawm solubility, thiab tsis yog-thermal gelation;
2.Nws tsis yog-ionic thiab tuaj yeem ua rau neeg nyiam nrog ntau yam ntawm lwm cov dej-soluble polymers, solfactants, thiab ntsev. Nws yog ib qho zoo tshaj plaws colloidal thickener rau cov kev daws teeb meem muaj cov siab-siab cov dielessrics;
3.Qhov muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ob zaug kom ntau npaum li ntawm methyl cellulose, thiab nws tau ntws zoo dua ntws cov cai.
