Puas yog hydroxyethylcellulose nplaum?

Hydroxyethylcellulose (HEC)yog ib qho polymer uas siv ntau hauv ntau yam lag luam, suav nrog tshuaj, tshuaj pleev ib ce, thiab zaub mov. Nws cov khoom tuaj yeem sib txawv nyob ntawm cov yam xws li kev sib xyaw, qhov hnyav molecular, thiab qhov muaj lwm cov khoom xyaw. Txawm hais tias HEC nws tus kheej tsis nplaum, nws lub peev xwm los tsim cov gels lossis cov tshuaj tuaj yeem ua rau muaj cov qauv nplaum nyob rau hauv qee qhov xwm txheej.

HEC yog ib qho polymer uas tsis yog ionic uas yaj tau hauv dej los ntawm cellulose. Nws lub luag haujlwm tseem ceeb yog ua tus neeg sawv cev thickening, stabilizer, lossis zaj duab xis-former hauv cov khoom xws li cov khoom siv tu tus kheej xws li tshuaj zawv plaub hau thiab tshuaj pleev rau cov tshuaj thiab cov khoom noj. Nws cov qauv molecular ua rau nws cuam tshuam nrog cov dej molecules, tsim cov hydrogen bonds thiab tsim cov kua nplaum lossis gels.

Qhov nplaum ntawm cov khoom uas muaj HEC tuaj yeem cuam tshuam los ntawm ntau yam:

Kev Ntsuas: Kev ntsuas ntau ntawm HEC hauv cov qauv tuaj yeem ua rau muaj viscosity ntau dua thiab muaj peev xwm nplaum dua. Cov neeg tsim cov qauv ua tib zoo kho qhov kev ntsuas ntawm HEC kom ua tiav qhov sib xws xav tau yam tsis ua rau cov khoom nplaum dhau.
Kev sib cuam tshuam nrog lwm cov khoom xyaw:HECtuaj 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 qauv tshwj xeeb, cov kev cuam tshuam no tuaj yeem ua rau lo.
Tej yam ib puag ncig: Tej yam xws li kub thiab av noo tuaj yeem cuam tshuam rau tus cwj pwm ntawm cov khoom uas muaj HEC. Piv txwv li, nyob rau hauv cov chaw noo noo, HEC gels yuav khaws tau ntau cov av noo los ntawm huab cua, uas ua rau nws nplaum ntxiv.
Txoj kev siv: Txoj kev siv kuj tseem tuaj yeem cuam tshuam rau qhov kev xav ntawm kev nplaum. Piv txwv li, cov khoom uas muaj HEC yuav tsis nplaum thaum siv sib npaug, tab sis yog tias cov khoom ntau dhau tseem nyob ntawm daim tawv nqaij lossis plaub hau, nws yuav zoo li nplaum.
Qhov hnyav molecular: Qhov hnyav molecular ntawm HEC tuaj yeem cuam tshuam nws lub peev xwm thickening thiab cov qauv ntawm cov khoom kawg. Qhov hnyav molecular siab dua HEC yuav ua rau muaj cov kua nplaum ntau dua, uas tuaj yeem ua rau lo.
Hauv cov tshuaj pleev ib ce, HEC feem ntau siv los muab cov qauv du thiab creamy rau cov tshuaj pleev thiab cov tshuaj pleev ib ce yam tsis tawm cov khoom seem nplaum. Txawm li cas los xij, yog tias tsis tau tsim lossis siv kom raug, cov khoom uas muaj HEC tuaj yeem hnov ​​​​​​tias tacky lossis nplaum rau ntawm daim tawv nqaij lossis plaub hau.

thaumhydroxyethylcelluloseNws tus kheej tsis yog nplaum, nws siv rau hauv cov qauv tuaj yeem ua rau cov khoom muaj ntau qib ntawm kev nplaum nyob ntawm cov yam ntxwv ntawm cov qauv thiab cov txheej txheem siv. Cov neeg tsim cov qauv ua tib zoo sib npaug cov yam ntxwv no kom ua tiav cov qauv thiab kev ua tau zoo hauv cov khoom kawg.
