Celluloseether

Cellulose ether yog ib tsev neeg ntawm cov tshuaj hloov kho cellulose derivatives uas tau siv dav hauv ntau yam kev lag luam thiab cov khoom siv. Cellulose ethers yog tsim los ntawm chemically hloov tej yam ntuj tso cellulose fibers los yog pulp, feem ntau los ntawm ib tug tshuaj tiv thaiv nrog ib tug alkali los yog ib tug etherifying tus neeg sawv cev. Cov txiaj ntsig tau hloov kho cellulose molecules tau txhim kho solubility, dej tuav, thiab thickening zog, uas ua rau lawv muaj txiaj ntsig hauv ntau yam kev siv.

Qee qhov kev siv ntawm cellulose ethers muaj xws li:

Kev tsim kho: Cellulose ethers tau siv dav hauv kev tsim kho kev lag luam raws li cov khoom ntxiv hauv cov cement, mortar, thiab lwm yam khoom siv hauv tsev. Lawv txhim kho kev ua haujlwm, adhesion, thiab dej tuav ntawm cov ntaub ntawv no, uas tuaj yeem txhim kho qhov zoo thiab kav ntev ntawm cov khoom kawg.

Khoom noj khoom haus thiab dej haus: Cellulose ethers yog siv los ua thickening agents, stabilizers, thiab emulsifiers nyob rau hauv ib tug ntau yam ntawm cov khoom noj thiab dej haus, nrog rau cov zaub xam lav, kua ntses, ice cream, thiab ci.

Pharmaceuticals: Cellulose ethers yog siv los ua excipients nyob rau hauv cov tshuaj formulations los txhim kho cov stability, solubility, thiab bioavailability ntawm active cov khoom xyaw.

Cov khoom siv tu tus kheej: Cellulose ethers yog siv rau hauv ntau yam khoom siv tu tus kheej, xws li tshuaj zawv plaub hau, tshuaj pleev ib ce, thiab tshuaj pleev ib ce, los muab kev ntxhib los mos, viscosity, thiab lwm yam khoom zoo.

Qee hom cellulose ethers muaj xws li:

Methyl cellulose (MC): MC yog cov dej-soluble cellulose ether uas tau siv dav los ua tus neeg sawv cev thickening, binder, thiab emulsifier hauv ntau yam khoom lag luam thiab cov neeg siv khoom.

Hydroxyethyl cellulose (HEC): HEC yog cov dej-soluble cellulose ether uas feem ntau yog siv los ua cov thickening agent thiab stabilizer hauv cov khoom tu tus kheej thiab cov tshuaj formulations.

Carboxymethyl cellulose (CMC): CMC yog cov dej-soluble cellulose ether uas yog dav siv los ua ib tug thickening tus neeg sawv cev, binder, thiab stabilizer nyob rau hauv ib tug ntau yam ntawm kev lag luam thiab cov neeg siv khoom, nrog rau cov zaub mov, dej haus, thiab cov khoom tu tus kheej.
