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

Cellulose ethers yog ib pawg ntawm cov dej-soluble polymers muab tau los ntawm cellulose, cov organic polymer ntau tshaj plaws hauv ntiaj teb. 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 thiab lawv siv:

1. Methyl Cellulose (MC):
   • MC yog dav siv los ua cov thickener, stabilizer, thiab emulsifier hauv ntau yam lag luam, suav nrog zaub mov, tshuaj, thiab kev tsim kho.
   • Hauv kev lag luam khoom noj khoom haus, MC yog siv rau hauv cov khoom xws li ice creams, sauces, thiab bakery khoom los muab kev ntxhib los mos thiab ruaj khov.
   • Hauv kev tsim kho kev lag luam, MC yog siv hauv mortar, pobzeb nplaum, thiab cov khoom siv gypsum los txhim kho kev ua haujlwm thiab kev tuav dej.
2. Hydroxyethyl Cellulose (HEC):
   • HEC feem ntau yog siv los ua cov thickener, binder, thiab zaj duab xis-yav dhau los hauv cov khoom tu tus kheej, tshuaj, thiab xim.
   • Hauv cov khoom tu tus kheej, HEC yog siv rau hauv cov tshuaj zawv plaub hau, tshuaj pleev ib ce, thiab tshuaj pleev ib ce los muab cov viscosity, kev ntxhib los mos, thiab cov khoom khaws dej noo.
   • Hauv kev lag luam tshuaj, HEC yog siv los ua ib qho kev sib khi hauv cov tshuaj ntsiav tshuaj thiab ua tus hloov kho viscosity hauv qhov ncauj tshem tawm.
   • Nyob rau hauv cov xim thiab txheej, HEC yog siv los txhim kho kev ntws, theem, thiab kev tsim zaj duab xis.
3. Hydroxypropyl Methylcellulose (HPMC):
   • HPMC tau siv dav hauv kev tsim kho, tshuaj, khoom noj, thiab kev lag luam tu tus kheej.
   • Hauv kev tsim kho, HPMC yog siv hauv cov cement-based mortars, renders, thiab pobzeb adhesives ua tus neeg saib xyuas dej thiab kev ua haujlwm ntxiv.
   • Hauv cov tshuaj, HPMC yog siv los ua ib qho kev sib khi, disintegrant, thiab tswj-tso tus neeg sawv cev hauv cov tshuaj ntsiav tshuaj.
   • Hauv kev lag luam zaub mov, HPMC yog siv los ua cov thickener, stabilizer, thiab gelling tus neeg sawv cev hauv cov khoom xws li kua ntses, kua zaub, thiab khoom qab zib.
   • Hauv cov khoom siv tu tus kheej, HPMC yog siv rau hauv cov tshuaj txhuam hniav, cov khoom tu plaub hau, thiab cov tshuaj kho qhov muag rau nws cov thickening thiab film-forming zog.
4. Carboxymethyl Cellulose (CMC):
   • CMC feem ntau yog siv los ua cov thickener, stabilizer, thiab dej-retention agent nyob rau hauv cov zaub mov, tshuaj, textiles, thiab ntawv industries.
   • Hauv kev lag luam khoom noj khoom haus, CMC yog siv rau hauv cov khoom xws li ice cream, khoom noj siv mis, thiab kua ntses los txhim kho kev ntxhib los mos, ruaj khov, thiab txee lub neej.
   • Hauv kev lag luam tshuaj, CMC yog siv los ua cov ntawv khi rau hauv cov ntsiav tshuaj formulations, tus neeg sawv cev tshem tawm hauv qhov ncauj tshem tawm, thiab cov roj nplua nyeem hauv cov tshuaj pleev ib ce.
   • Hauv textiles, CMC yog siv los ua tus neeg sawv cev sizing thiab thickener hauv textile printing pastes.
   • Hauv kev lag luam ntawv, CMC yog siv los ua txheej txheej thiab sizing tus neeg sawv cev los txhim kho daim ntawv lub zog thiab luam tawm.
5. Polyanionic Cellulose (PAC):
   • PAC feem ntau yog siv rau hauv kev lag luam roj thiab roj raws li cov kua dej-tso tswj additive hauv cov dej drilling los txhim kho qhov zoo ntawm kev ruaj ntseg thiab tiv thaiv kev puas tsuaj.
   • PAC pab txo cov kua dej los ntawm kev tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa ntawm lub qhov dej, yog li tswj kom muaj kev ncaj ncees thiab txo qis cov teeb meem xws li cov yeeb nkab daig thiab ploj mus.

cellulose ethers ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv hauv kev lag luam, muab cov haujlwm tshwj xeeb thiab kev ua tau zoo rau ntau yam khoom thiab cov txheej txheem.
