Hydroxypropyl Methylcellulose
HydroxypropylMethylcellulose (HPMC) los yog hypromelloseyog derivatives ntawm Methyl cellulose ethers. Nws yogib tug dawb los yog off-dawb fibrous los yog granularcellulose etherhmoov. Tam sim no nws yog cellulose ethers nrog kev ua tau zoo tshaj plaws hauv ntiaj teb, kev sib xyaw ua kom tuab, tshem tawm, dispersing, emulsifying thiab stabilizing. Hydroxypropyl methyl cellulose (HPMC) yog non-toxic, yooj yim rau siv, thiab yooj yim soluble hauv dej. Nws yog polyanion hauv cov kua dej aqueous thiab muaj lub cev tshwj xeeb. Qhov kev ua haujlwm tshwj xeeb yog raws li hauv qab no:

HPMC Phau Ntawv QhiaCov lus qhia:
1. Cov txheej txheem dej kub: Ntxiv 1/3 lossis 2/3 ntawm cov dej hauv lub thawv thiab cua sov kom siab tshaj 80. Thawj hydroxypropyl methyl cellulose(HPMC) tuaj yeem sib npaug hauv cov dej kub, thiab tom qab ntawd ntxiv cov dej txias ntxiv rau hauv cov dej kub slurry, txias tom qab nplawm.
2. Txoj kev sib tov hmoov: sib tov cov hydroxypropyl methyl cellulose(HPMC) hmoov nrog ib tug loj npaum li cas ntawm lwm cov hmoov cov khoom xyaw, kom huv si disperse nws los ntawm qhuav mix, thiab ces ntxiv dej rau dissolve nws..
3. Organic hnyav wetting method: thawj disperse los yog ntub dej hydroxypropyl methyl cellulose (HPMC) nrog cov organic hnyav, thiab tom qab ntawd ntxiv dej kom yaj nws.
