Cellulose Ether (HPMC, MC, HEC, EC, HPC, CMC, PAC)

Cellulose ethers yog ib pab pawg ntawm cov dej-soluble polymers muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag cell phab ntsa.Lawv tau siv dav hauv ntau qhov kev lag luam rau lawv cov thickening, stabilizing, film-forming, thiab dej-retention zog.Nov yog cov ntsiab lus luv luv ntawm qee hom cellulose ethers:

1. Hydroxypropyl Methylcellulose (HPMC): HPMC yog ntau yam cellulose ether uas tau siv dav hauv kev tsim kho, tshuaj, kev saib xyuas tus kheej, thiab kev lag luam zaub mov.Nws yog lub npe hu rau nws cov dej tuav zoo heev, thickening, thiab zaj duab xis-forming zog.HPMC feem ntau yog siv los ua cov thickener, binder, thiab rheology modifier hauv mortar, tile adhesives, tshuaj ntsiav tshuaj, tshuaj pleev ib ce, thiab khoom noj khoom haus.
2. Methylcellulose (MC): MC zoo ib yam li HPMC tab sis muaj qis dua ntawm kev hloov pauv nrog methyl pawg.Nws yog siv rau hauv cov ntawv thov uas yuav tsum tau txo qis dej thiab viscosity, xws li hauv cov tshuaj formulations, ophthalmic daws, thiab ua cov thickener hauv cov khoom noj.
3. Hydroxyethyl Cellulose (HEC): HEC yog lwm cov khoom siv cellulose ether paub txog nws cov dej tuav tau zoo thiab cov khoom ua kom tuab.Nws yog feem ntau siv rau hauv cov khoom siv xws li xim pleev xim, coatings, thiab cov nplaum, nrog rau cov khoom tu tus kheej xws li tshuaj zawv plaub hau, tshuaj pleev, thiab tshuaj pleev.
4. Ethyl Cellulose (EC): EC yog cellulose ether hloov nrog ethyl pawg.Nws yog feem ntau siv hauv cov tshuaj, coatings, thiab cov ntawv thov tshwj xeeb uas nws cov yeeb yaj kiab tsim, thaiv, thiab cov khoom tso tawm tau zoo.EC feem ntau yog siv los ua cov khoom siv txheej rau cov ntsiav tshuaj thiab pellets hauv cov tshuaj formulations.
5. Hydroxypropyl Cellulose (HPC): HPC yog cellulose ether hloov nrog hydroxypropyl pawg.Nws feem ntau yog siv los ua cov thickener, binder, thiab zaj duab xis-tsim tus neeg sawv cev hauv cov tshuaj, cov khoom tu tus kheej, thiab daim ntawv thov zaub mov.HPC muab kev solubility zoo heev, viscosity tswj, thiab kev ruaj ntseg hauv cov tshuaj aqueous.
6. Carboxymethyl Cellulose (CMC): CMC yog dej-soluble cellulose ether muab los ntawm cellulose los ntawm carboxymethylation.Nws yog dav siv los ua cov thickener, stabilizer, thiab binder hauv cov khoom noj khoom haus, tshuaj, khoom siv tu tus kheej, thiab kev siv hauv kev lag luam.CMC cov ntaub ntawv ntshiab, viscous daws thiab feem ntau yog siv los ua tus neeg sawv cev thickening hauv cov kua ntses, hnav khaub ncaws, thiab qhov ncauj tshem tawm.
7. Polyanionic Cellulose (PAC): PAC yog cellulose ether hloov nrog anionic pawg, feem ntau carboxymethyl lossis phosphonate pawg.Nws yog feem ntau yog siv los ua cov kua dej poob tswj additive nyob rau hauv drilling kua rau kev tshawb nrhiav roj thiab roj.PAC pab txo cov dej poob, txhim kho viscosity, thiab ruaj khov drilling av nkos nyob rau hauv high-temperature thiab high-pressure tej yam kev mob.

Cov cellulose ethers no muaj ntau yam kev ua haujlwm thiab kev siv thoob plaws ntau yam kev lag luam, pab txhawb kev ua haujlwm, ruaj khov, thiab zoo ntawm ntau yam khoom thiab cov qauv tsim.
