HEC (Hydroxyethyl cellulose) yog tsis-ionic dej-soluble cellulose cellulose ether uas tau siv dav hauv ntau yam kev lag luam. Tau los ntawm cellulose, HEC yog ib qho ntau yam polymer nrog ntau yam khoom uas ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm HEC yog nws lub peev xwm los ua kom cov kua a aqueous. Cov cuab yeej no ua rau nws yog tus neeg sawv cev tuab ntawm kev lag luam xws li tshuaj pleev ib ce, tshuaj, thiab kev lag luam khoom noj. Hauv cov tshuaj pleev ib ce, HEC feem ntau yog siv nyob rau hauv cov khoom lag luam xws li lotions, cream, thiab tshuaj zawv plaub hau kom muab du, creamy kev ntxhib los mos. Hauv cov chaw kuaj tshuaj, nws yog siv los txhawm rau ncua qhov ncauj thiab lwm yam tshuaj noj kua. Hauv kev lag luam khoom noj khoom haus, HEC yog siv los ua cov tuab hauv cov khoom lag luam xws li cov kua nplaum, hnav khaub ncaws, thiab kua zaub.
Ib cag ntawm nws cov khoom siv thickening, HEC tseem muaj cov dej ua kom muaj kev txuag dej zoo. Qhov no ua rau nws muaj txiaj ntsig hauv cov khoom xws li cov nplaum, thiab cov khoom siv, qhov twg nws pab txhim kho qhov chaw ruaj khov thiab kev ua tau zoo ntawm cov khoom kawg. Hauv kev tsim kho kev tsim kho, HEC yog siv hauv cov cai hloov kho kom txhim kho kev ua haujlwm ua haujlwm thiab txo kev siv dej.
HEC tseem muaj lub npe rau nws cov yeeb yaj kiab ua yeeb yam, uas ua rau nws muaj cov khoom siv zoo tagnrho xws li txheej ci, cov yeeb yaj kiab, thiab cov cai. Nws yog feem ntau siv nyob rau hauv kev tsim cov yeeb yaj kiab biodegradable thiab txheej rau cov ntaub ntawv ntim khoom thiab kev siv ua liaj ua teb.
Tsis tas li ntawd, HEC yog qhov ua tau zoo rheology kho kom zoo, lub ntsiab lus nws tuaj yeem tswj hwm qhov dej ntws thiab viscosity ntawm cov dej. Cov cuab yeej no ua rau nws yog cov khoom tseem ceeb hauv cov khoom xws li inks, detergents, thiab drilling kua. Hauv kev lag luam tshuaj pleev ib ce, HEC yog siv los tswj cov kev ntws thiab kev ntxhib los mos zoo li mascaras thiab gels.
Hauv kev xaus, HEC yog qhov muaj ntau yam muaj txiaj ntsig hauv ntau qhov kev lag luam vim nws cov khoom siv tshwj xeeb xws li thickening, dej ceev, kev sib sau ua yeeb yaj kiab, thiab rheology tswj, thiab rheology tswj, Nws cov kev siv dav dav hauv kev lag luam xws li tshuaj pleev ib ce, chaw ua tshuaj, kev tsim kho, thiab tseem ceeb dua li cov khoom tseem ceeb hauv ntau cov khoom peb siv txhua hnub.
