HydroxyPropyyl methylcellulose (HPMC)yog cov tshuaj polymer polymer siv ntau yam kev lag luam xws li kev tsim kho, chaw muag tshuaj, tshuaj pleev ib ce, thiab khoom noj. Nws yog cov khoom ua los ntawm cellulose los ntawm kev siv tshuaj lom neeg muaj kuab lom, yog cov yeeb yaj kiab zoo, yog li nws muaj cov ntawv thov kev lag luam thiab kev lag luam.
1. Cov qauv thiab cov khoom
HPMC tau txais los ntawm ob kauj ruam kev hloov pauv cov tshuaj tiv thaiv ntawm cov molecules molecules. Ua ntej, cov methyl pawg yog qhia los ntawm methylation cov tshuaj tiv thaiv kom tau txais methyl cellulose (MC). Tom qab ntawd, HydroxyPropyf methylcellulose tau txais los ntawm reachoyl pab pawg hauv cellulose molecule nrog cov pab pawg hydroxle. Nws cov qauv molecat muaj ob pawg hydrophilic, hydroxypropsyl thiab methyl, uas muab Kimacell®
Hauv kev daws, HPMC cov khoom ua pov thawj zoo heev dej solubility thiab colloidal yam ntxwv, thiab tuaj yeem tsim cov tshuaj uas tsis muaj kuab. Nws cov solubility yog cuam tshuam los ntawm cov qib ntawm hydroxypropyl thiab methyl nyob rau hauv lub lwg me thiab cov molecule. Hloov hnyav li cas los hloov chaw hnyav thiab cov tes hnyav molecular tuaj yeem hloov kho lub solubility thiab viscosity ntawm cov kev cai sib txawv.
2. Cov yam ntxwv tseem ceeb
2.1 thickening
HPMC muaj cov nyhuv tuab tuab thiab tuaj yeem ua kom muaj viscosity ntawm kev daws teeb meem. HPMC tau dav siv los ua tuab ntawm kev lag luam xws li kev tsim kho, txheej thiab tshuaj pleev ib ce. Nws tsis tuaj yeem txhim kho kev sib xws ntawm cov khoom lag luam, tab sis kuj tseem txhim kho cov rhuaology thiab kev thov ua haujlwm ntawm cov khoom.

Piv txwv li, hauv kev npaj tshuaj, HPMC feem ntau siv los ua tus neeg sawv cev tso tawm los tswj cov tshuaj tso tawm; Hauv cov tshuaj pleev ib ce, feem ntau nws siv los ua ib zaj duab xis los txhim kho cov nyhuv yahuab.
2.3 solubility
HPMC dissolves zoo nyob rau hauv dej txias thiab yaj tawm sai sai. Nws solubility yog qhov ruaj khov ntawm cov txiaj ntsig sib txawv, uas ua rau nws ua qhov ua tau zoo tshaj plaws nyob rau ntau yam.
2.4 emulsification thiab dispersibility
HPMC tuaj yeem ua raws li emulsifier los pab ntsuas sib txawv ntawm cov tshuaj sib xyaw zoo dua. Nws qhov kev tawm tsam ua rau nws cov cab kuj rau cov khoom lag luam xws li cov pigments thiab tshuaj, uas pab txhim kho kev ruaj khov thiab kev sib txuam ntawm cov khoom lag luam.
2.5 Kev tiv thaiv ib puag ncig thiab kev nyab xeeb
Raws li lub ntuj cog cellulose derivative, HPMC muaj qhov zoo biodegradity, tsis muaj kev phom sij thiab tsis muaj tshuaj lom, thiab ua tau raws li cov kev xav tau ntawm cov kev xav tau tshiab. Yog li ntawd, HPMC tau siv dav hauv kev tsis muaj mob thiab ib puag ncig cov neeg siv khoom, tshwj xeeb hauv cov zaub mov, tshuaj lag luam thiab tshuaj pleev ib ce thiab tshuaj pleev ib ce thiab kho kom zoo nkauj.
3. Cov chaw thov
3.1 Kev Tsim Kho Kev Tsim Kho
Hauv kev tsim kho kev tsim kho, HPMC feem ntau yog siv los ua kev ntxiv rau cov cement cug. Nws tuaj yeem txhim kho qhov ua haujlwm cug, txhim kho cov nplaum ntawm cug, thiab muaj lub sijhawm qhib, ua kev tsim kho kom yooj yim dua. Tsis tas li ntawd, HPMC kuj tseem tuaj yeem txhim kho lub tawg tsis kam thiab dej tsis kam ntawm tshuaj cug.
3.2 Kev lag luam kws tshuaj
Hauv kev lag luam kws tshuaj, Kimacell® yog siv los ua cov tshuaj tswj tso tawm tus neeg sawv cev, emulsifier thiab zaj duab xis-ua tus neeg sawv cev rau cov ntsiav tshuaj. Vim nws cov kev ua tau zoo biocompatibility thiab biodegradability, hpmc tau siv dav hauv kev npaj tshuaj, uas tuaj yeem tswj hwm cov tshuaj lom zem thiab ncua cov tshuaj.
3.3 Kev lag luam khoom noj khoom haus
HPMC, raws li cov zaub mov ntxiv, feem ntau siv hauv cov mis nyuj khov, pastries, kua txiv thiab lwm yam khoom, feem ntau yog rau thickening, ruaj khov thiab emulsification thiab emulsification thiab emulsification. Nws tuaj yeem nce cov saj thiab kev ntxhib los mos thiab txuas lub txee lub neej.
3.4 Cov Tshuaj Pleev Kev Lag Luam
HPMC tau siv dav hauv cov tshuaj pleev ib ce teb, tshwj xeeb tshaj yog nyob rau hauv lotions, cream, tshuaj zawv plaub hau thiab lwm yam khoom. Nws tsis tsuas yog ua lub luag haujlwm ntawm thickening thiab emulsification, tab sis kuj muab cov kev tu xyuas cov tawv nqaij zoo, xws li moisturizing thiab anti-oxidation.
