HydroxyPropyyl Methylcellulose
HydroxyPropylMEthylcellaus (HPMC) lossis hypromelloseyog ib tug derivatives ntawm methyl cellulose lus coj neeg. Nws yogib tug dawb lossis off-dawb fibrous lossis granularCellulose etherHmoov. Nws yog tam sim no lub cellulose lus coj neeg Nrog rau kev ua tau zoo tshaj plaws hauv lub ntiaj teb, kev sib koom ua ke tuab, ncua, dispersing, emulsifying thiab ruaj khov. HydroxyPropyyl Methyl cellulose (HPMC) Yog tsis muaj tshuaj lom, siv tau yooj yim, thiab yooj yim soluble hauv dej. Nws yog Polyanion nyob rau hauv cov kua aqueous thiab muaj cov khoom siv lub cev tshwj xeeb. Cov kev ua tau zoo yog raws li pawg:
