Yog lawm, cationic Hydroxyethyl cellulose (HEC) tuaj yeem ua haujlwm ua cov thickener. Hydroxyethyl cellulose yog ib qho uas tsis yog-ionic derivative ntawm cellulose uas yog dav siv los ua ib tug thickening tus neeg sawv cev nyob rau hauv ntau yam lag luam, nrog rau kev tu tus kheej, khoom siv hauv tsev, tshuaj, thiab cov ntaub ntawv tsim kho.

Cationic Hydroxyethyl cellulose yog ib daim ntawv hloov kho ntawm HEC uas muaj cov pab pawg zoo, hu ua quaternary ammonium pawg. Cov pab pawg cationic no muab cov khoom tshwj xeeb rau cov polymer, suav nrog kev txhim kho kev sib raug zoo nrog qee hom kev tsim thiab txhim kho qhov tseem ceeb rau qhov chaw tsis zoo.

Raws li ib tug thickener, cationic Hydroxyethyl cellulose ua hauj lwm los ntawm kev tsim ib tug network ntawm polymer chains thaum dispersed nyob rau hauv dej los yog lwm yam kuab tshuaj. Cov qauv network no tau txais txiaj ntsig zoo thiab tuav cov dej molecules, ua kom cov viscosity ntawm cov tshuaj los yog dispersion. Lub degree ntawm thickening nyob ntawm tej yam xws li cov concentration ntawm cov polymer, qhov hnyav molecular ntawm lub polymer chains, thiab cov shear npaum li cas siv rau lub cev.

Cationic Hydroxyethyl cellulose yog tshwj xeeb tshaj yog pab tau raws li ib tug thickening neeg sawv cev nyob rau hauv formulations qhov twg nws cationic xwm muab kev pab ntxiv. Piv txwv li, nws tuaj yeem txhim kho cov khoom siv hauv cov khoom tu plaub hau, txhim kho kev tso tawm mus rau qhov chaw hauv kev tu cov qauv, lossis txhim kho adhesion rau substrates hauv qee yam khoom siv.

cationic Hydroxyethyl cellulose yog cov khoom siv ntau yam polymer uas tuaj yeem ua cov thickener zoo nyob rau hauv ntau hom kev siv, muab viscosity tswj, ruaj khov, thiab lwm yam khoom tsim nyog rau cov khoom tsim.
