Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose(HEC)
CAS:9004-62-0
Hydroxyethyl Cellulose(HEC) yog cov dej-soluble cellulose ether uas tsis yog ionic, siv ua cov khoom tuab, tiv thaiv colloid, tus neeg sawv cev khaws dej thiab rheology modifier hauv ntau daim ntawv thov xws li cov xim dej, cov ntaub ntawv tsim kho, cov tshuaj roj thiab cov khoom siv tu tus kheej. Vim nws cov khoom tshwj xeeb, xws li viscosity siab, solubility hauv dej kub thiab txias, thiab tshuaj lom neeg ruaj khov, HEC yog cov khoom tseem ceeb hauv ntau yam khoom lag luam thiab cov neeg siv khoom.
HEC yog synthesized los ntawm kev qhia cov hydroxyethyl pawg (-CH₂CH₂OH) rau hauv cov saw hlau cellulose polymer los ntawm kev sib xyaw ua ke. Qhov kev hloov kho no txhim kho nws cov dej solubility, thickening peev xwm, thiab kev sib raug zoo nrog ntau hom formulations.

Cov Kev Zoo Tseem Ceeb:
1. Kev Khaws Dej Zoo Kawg Nkaus: Pab tiv thaiv kom cov khoom siv cement thiab cov tshuaj pleev ib ce tsis qhuav ua ntej lub sijhawm.
2. Ruaj Khoov Thoob Plaws Qhov Ntau pH: Tseem ua haujlwm tau zoo hauv cov chaw acidic, nruab nrab, thiab alkaline.
3. Tsis yog Ionic thiab Sib xws: Ua haujlwm zoo nrog ntau yam tshuaj, suav nrog cov ntsev, surfactants, thiab lwm yam polymers.
4. Txhim Kho Kev Ua Haujlwm ntawm Khoom: Txhim kho qhov tuab, kev nplaum, kev tsim zaj duab xis, thiab cov khoom emulsification.
5. Ib puag ncig zoo thiab Biodegradable: Muab los ntawm cellulose, HEC tsis yog tshuaj lom thiab biodegradable.
6. Txhim kho Rheology thiab Flow Properties: Tso cai rau kev tswj viscosity, tiv thaiv dripping, sagging, thiab kev sib cais theem.
Ntim:
Cov khoom HEC tau ntim rau hauv peb txheej hnab ntawv nrog lub hnab polyethylene sab hauv, qhov hnyav tag nrho yog 25kg ib lub hnab.
Kev Khaws Cia:
Khaws cia rau hauv qhov chaw txias thiab qhuav, deb ntawm cov dej noo, hnub, hluav taws, los nag.
