hydroxy methyl propyl cellulose
Hydroxypropyl methyl cellulose (HPMC) yog non-ionic cellulose ether tau los ntawm cellulose alkalization, etherification, neutralization thiab ntxuav.HPMC muaj cov thickening zoo, dispersing, emulsifying, zaj duab xis-forming zog, thiab lwm yam. Nws yog thawj qhov kev xaiv rau zus tau tej cov ntaub ntawv zoo hauv tsev additives.Nyob rau hauv lub tsev cov ntaub ntawv, tus nqi ntxiv ntawm HPMC yog tsawg heev, tsuas yog 0.1% -1%, tab sis nws ua lub luag haujlwm tsis tuaj yeem hloov pauv thiab tuaj yeem txhim kho cov dej tuav, fluidity thiab lubrication ntawm cov khoom siv hauv tsev.Cov khoom siv hauv tsev ntxiv nrog HPMC yog qhov yooj yim rau kev sib xyaw thiab siv, txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm tsim kho, txuas ntxiv lub sijhawm qhib, txhim kho kev sib koom ua ke, thiab tsim cov txheej txheem du thiab ilv.
