Dab tsi yog HEC?

Hydroxyethyl cellulose(HEC) yog tsis-ionic, dej-soluble polymer muab tau los ntawm cellulose, lub ntuj polymer pom nyob hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Nws yog ib qho siv nyob rau hauv ntau yam kev lag luam, suav nrog cov tshuaj, cov khoom ntiag tug, thiab kev tsim kho kev tsim kho. HEC yog muaj nuj nqis rau nws cov thickening, gelling, thiab stabilizing tej yam ntxwv nyob rau hauv aqueous kev daws teeb meem.

Nov yog qee cov yam ntxwv tseem ceeb thiab siv cov cellulethethyl cellulose (HEC):

Cov yam ntxwv:

1. Dej solubility: HEC yog soluble hauv dej, thiab nws solubility yog pawg xws li kub thiab siab.
2. Tus neeg saib xyuas tuab: Ib qho ntawm thawj siv HEC yog li tus neeg sawv cev ua kom tuab hauv cov dej ua ke. Nws imparts viscosity rau kev daws teeb meem, ua rau lawv ruaj khov dua thiab muab cov ntawv xav tau.
3. Tus neeg sawv cev rau tus kheej: HEC muaj peev xwm los ua cov tshuaj pleev ib ce, ua rau muaj kev nyab xeeb thiab sib txawv ntawm cov khoom gelled.
4. Zaj duab xis-ua yeeb yaj kiab: HEC tuaj yeem ua cov yeeb yaj kiab thaum ua ntawv thov rau cov ntaub ntawv xws li cov khoom siv, cov khoom nplaum, thiab cov khoom saib xyuas tus kheej.
5. Tus neeg sawv cev: HEC feem ntau siv los ua kom muaj emulsions thiab ncua hauv ntau yam kev ua tiav, tiv thaiv kev sib cais ntawm theem.
6. Kev sib raug zoo: Hec yog sib xws nrog ntau ntau ntawm lwm cov khoom xyaw, ua rau nws muaj ntau yam hauv cov qauv.

Siv:

1. Kws Tshuaj:
   • Hauv cov yeeb yaj kiab kws tshuaj, cov tshuaj hec yog siv los ua cov binder, tuab dua, thiab stabilizer hauv cov tshuaj thiab ncauj lus.
2. Cov khoom lag luam ntawm tus kheej:
   • HEC yog ib qho khoom siv sib xyaw rau hauv cov khoom lag luam saib xyuas ntawm tus kheej xws li tshuaj zawv plaub hau, cov khoom noj kom zoo, pleev tshuaj, thiab cream. Nws muab viscosity, txhim kho kev ntxhib los mos, thiab txhim kho cov khoom ruaj khov.
3. Xim thiab pleev xim:
   • Nyob rau hauv cov xim thiab pleev xim kev lag luam, HEC yog siv los ua tuab thiab ua kom ruaj khov. Nws pab txhawb rau cov xim sib txawv thiab pab tiv thaiv kev tsis txaus siab.
4. Cov nplaum:
   • HEC tau siv nyob rau hauv cov nplaum kom txhim kho lawv cov viscosity thiab cov khoom muaj txiaj ntsig. Nws pab txhawb rau kev nyuaj siab thiab lub zog ntawm cov nplaum.
5. Cov Khoom Siv Siv:
   • Hauv kev tsim kho kev tsim kho, HEC tau ua haujlwm hauv cov khoom siv cov cement-raws li cov nplais nplaum thiab sib koom ua ke, txhawm rau txhim kho kev ua haujlwm thiab kev sib koom tes.
6. Roj thiab roj drilling kua:
   • HEC yog siv rau hauv cov dej khiav hauv cov roj thiab roj kev lag luam kom tswj viscosity thiab muab kev ruaj khov.
7. Detgents:
   • HEC tuaj yeem pom nyob hauv qee cov tshuaj ntxuav tes, ua rau muaj kev ua kom tuab ntawm cov tshuaj ntxuav ua kua.

Nws yog ib qho tseem ceeb kom nco ntsoov tias cov cim tshwj xeeb thiab cov yam ntxwv ntawm HEC tuaj yeem sib txawv, thiab xaiv ntawm HEC rau ib qho kev thov ntawm cov khoom kawg ntawm cov khoom kawg. Cov kws tsim khoom feem ntau muab cov ntaub ntawv cov ntaub ntawv los qhia txog kev siv kev tsim nyog ntawm HEC hauv cov qauv sib txawv.
