Bahlahisi ba li-ether tsa cellulose

Lebitso la lik'hemik'hale,Hydroxypropyl Methyl Cellulose (HPMC), Hydroxyethyl Methyl Cellulose (HEMC),Selulose ea Sodium Carboxymethyl (CMC), Hydroxyethyl cellulose (HEC), HEC e fetotsoeng ka hydrophobically (HMHEC),Selulose ea Methyl (MC),Methyl hydroxyethyl cellulose (MHEC),Ethyl hydroxyethyl cellulose (EHEC), Li-ether tsa cellulose tse fetotsoeng ka hydrophobically (EHEC, HM-EHEC).

Li-ether tsa cellulose li entsoe ka liphetoho tsa lik'hemik'hale tsa cellulose le lik'hemik'hale tse ling. Li-ether tsa cellulose ke li-polymer tse tloaelehileng tse qhibilihang metsing tse sa ionic tse thehiloeng ho cellulose ea polymer ea tlhaho e ngata ka ho fetisisa. Ka lilemo tse fetang 70, lihlahisoa tsena li bapetse karolo ea bohlokoa holim'a lits'ebetso tsena, ho tloha lihlahisoa tsa moralo, li-ceramics le lipente ho ea lijong, litlolo le meriana. Li-ether tsa cellulose li sebelisoa e le lik'hemik'hale tse sebetsang le tsa rheological le ts'ebetso e le li-ejensi tse tiisang, li-emulsifier, li-colloid tse sireletsang, li-stabilizer le hape bakeng sa ho boloka metsi.

Kahong, li-ether tsa cellulose li sebetsa e le li-thickeners, li-binder, li-former tsa lifilimi le li-agency tsa tlhokomelo tse sa hlalosoang ka metsi, li-suspension assists, li-surfactants, li-lubricant, li-colloid tse sireletsang le li-emulsifier. Ho feta moo, litlhare tsa metsi tsa li-ether tse itseng tsa cellulose li sebelisa gel ea mocheso, ntlo e ikhethang e nkang sebaka sa bohlokoa lits'ebetsong tse fapaneng. Motsoako ona oa bohlokoa oa litšobotsi ha o eo hoo e ka bang polymer e 'ngoe le e 'ngoe e qhibilihang ka har'a h2o.

Li-softwareng tse 'maloa, metsoako e mengata e tla hlokahala ho etsa mosebetsi o tšoanang o etsoang ke sehlahisoa se le seng sa ether ea cellulose. Ho feta moo, li-ether tsa cellulose li atlehile haholo, hangata li fana ka katleho e ntle ka ho fetisisa ho feta li-polymer tse ling tse nooang tse qhibilihang ka metsing.
