Yog hydroxyethylcellulose nplaum?

Hydroxyethylcellulose (HEC)Yog ib txwm siv polymer hauv ntau yam kev lag luam, suav nrog cov tshuaj, tshuaj pleev, khoom noj. Nws cov peev xwm tuaj yeem sib txawv raws li qee yam xws li lub siab, haum hnyav, thiab muaj lwm yam khoom xyaw. Thaum Hec nws tus kheej tsis muaj qhov nplaum, nws muaj peev xwm los ua cov tshuaj pleev lossis cov kev daws teeb meem tuaj yeem ua rau muaj cov qauv nplaum.

HEC yog cov dej tsis-ionic-soluble polymer muab tau los ntawm cellulose. Nws lub luag haujlwm tseem ceeb yog ua tus neeg saib xyuas tuab, stabilizer, lossis zaj duab xis-yav dhau los hauv cov khoom uas cov khoom saib xyuas tus kheej xws li cov tshuaj ntxuav tes thiab tshuaj pleev rau cov tshuaj thiab cov khoom lag luam khoom noj. Nws cov qauv molecular ua rau nws los cuam tshuam nrog cov lwg dej, ua cov hlua dej hydrogen thiab tsim cov kev daws teeb meem lossis cov gels enchous lossis gels.

Cov nplaum ntawm hec-muaj cov khoom lag luam tuaj yeem cuam tshuam los ntawm ntau yam:

Lub siab: kev txiav txim siab dua ntawm HEC hauv kev tsim muaj peev xwm ua rau viscosity ntau thiab cov khoom siv tau lo. Cov neeg ua tib zoo hloov kho cov hec kom ua tiav qhov kev xav tau yam tsis muaj kev ua kom zoo nkauj nplaum.
Kev sib cuam tshuam nrog lwm cov khoom xyaw:Tus patuaj yeem cuam tshuam nrog lwm cov khoom hauv cov qauv, xws li surfactants lossis ntsev, uas yuav hloov nws cov khoom rheological. Nyob ntawm cov kev tsim tshwj xeeb, cov kev sib cuam tshuam no tuaj yeem pab txhawb kom muaj kev nplaum.
Cov xwm txheej ib puag ncig: yam xws li kub thiab av noo tuaj yeem cuam tshuam tus cwj pwm ntawm hec-muaj cov khoom lag luam. Hauv cov chaw puag ncig huab cua noo, piv txwv li, HEC gels tej zaum yuav khaws ntau cov noo noo los ntawm huab cua, muaj peev xwm ua kom muaj peev xwm ntais ntawv nplaum.
Txoj kev thov cov txheej txheem: Cov qauv ntawm daim ntawv thov tuaj yeem cuam tshuam rau kev pom ntawm kev nplaum. Piv txwv li, cov khoom muaj hec tej zaum yuav muaj cov nplaum nplaum kom tsawg thaum thov komyees, tab sis yog tias cov khoom lag luam dhau los yog sab laug ntawm daim tawv nqaij lossis plaub hau, nws tuaj yeem xav tias yog qhov tsis zoo.
Molecular qhov hnyav: qhov hnyav molecular ntawm Hec tuaj yeem cuam tshuam nws lub peev xwm thickening thiab cov qauv ntawm cov khoom kawg. Lub cev hnyav dua qhov hnyav yuav ua rau cov kev daws teeb meem tau muaj kuab ntau dua, uas tuaj yeem pab txhawb kom muaj kev nplaum.
Hauv kev ua kom zoo nkauj, HEC feem ntau siv los muab cov ntawv ntshiab, creamy kom muaj cov tshuaj pleev thiab pleev xim yam tsis tau tawm ntawm cov ntawv nplaum. Txawm li cas los xij, yog tias tsis tsim nyog lossis siv, cov khoom uas muaj cov tawv nqaij tuaj yeem xav tias tawv nqaij lossis cov plaub hau.

thaumhydroxyethylcelluloseNws tus kheej tsis yog xam cov nplaum, nws siv hauv cov qauv tuaj yeem ua rau cov khoom lag luam sib txawv ntawm cov qauv ua haujlwm thiab cov txheej txheem kev siv. Cov ntawv sau ua tib zoo sib npaug nrog ua tiav cov kev xav tau thiab kev ua tau zoo hauv cov khoom kawg.
