Hydroxyethyl cellulose ether (9004-62-0)

Hydroxyethyl cellulose ether, nrog rau cov tshuaj formula (C6H10O5)n·(C2H6O)n, yog cov dej-soluble polymer muab tau los ntawm cellulose. Nws feem ntau hu ua hydroxyethylcellulose (HEC). CAS npe rau hydroxyethyl cellulose yog 9004-62-0.

HEC yog tsim los ntawm reacting alkali cellulose nrog ethylene oxide nyob rau hauv kev tswj tej yam kev mob. Cov khoom uas tau tshwm sim yog xim dawb mus rau dawb, tsis muaj ntxhiab, thiab tsis qab ntsev hmoov uas yog soluble hauv dej txias thiab kub. HEC yog siv nyob rau hauv ntau yam lag luam rau nws thickening, stabilizing, thiab zaj duab xis-tsim zog. Qee qhov kev siv ntau yam ntawm HEC suav nrog:

1. Cov Khoom Siv Kho Tus Kheej: HEC yog siv rau hauv cov tshuaj zawv plaub hau, tshuaj kho mob, tshuaj pleev ib ce, tshuaj pleev, thiab lwm yam khoom siv tu tus kheej ua tus neeg ua kom tawv nqaij, stabilizer, thiab binder.
2. Pharmaceuticals: Nyob rau hauv cov tshuaj formulations, HEC ua hauj lwm raws li ib tug thickening neeg sawv cev nyob rau hauv lub qhov ncauj kua, ib tug binder nyob rau hauv cov ntsiav tshuaj formulations, thiab ib tug stabilizer nyob rau hauv kev ncua.
3. Cov Khoom Siv Tsim Kho: HEC tau ntxiv rau cov khoom siv xws li cov nplais nplaum, cov cement renders, thiab gypsum-based plasters los txhim kho kev ua haujlwm thiab kev tuav dej.
4. Xim thiab Txheej: HEC yog siv los ua rheology modifier thiab thickener hauv cov xim dej, txheej, thiab cov nplaum los tswj cov viscosity thiab txhim kho daim ntawv thov.
5. Khoom noj khoom haus: HEC yog ua hauj lwm nyob rau hauv daim ntawv thov zaub mov xws li kua ntses, hnav khaub ncaws, thiab khoom qab zib raws li ib tug thickening thiab stabilizing tus neeg sawv cev.

HEC muaj nuj nqis rau nws ntau yam, sib haum nrog lwm cov khoom xyaw, thiab yooj yim ntawm kev siv ntau yam formulations. Nws pab txhawb rau kev ntxhib los mos, ruaj khov, thiab kev ua haujlwm ntawm cov khoom thoob plaws kev lag luam sib txawv.
