HydroxyPropyloosylcellulose (HPMC) yog cov polymer ua los ntawm kev kho cov cellulose ntuj. Nws muaj ntau yam kev lag luam muaj nyob hauv cov chaw muag tshuaj, khoom noj, tshuaj pleev ib ce, thiab kev tsim kho. HPMC yog cov kev cai nonicic ether yog yooj yim soluble hauv dej thiab tuaj yeem tsim lub pob tshab, cov tshuaj tau khov uas tseem nyob ruaj khov tshaj qhov dav dav.
Cov yam ntxwv ntawm HPMC suav nrog:
1. Cov dej nyob hauv siab: HPMC tuaj yeem nqus dej thiab tuav nws rau hauv qhov chaw, ua rau muaj txiaj ntsig zoo li lub thickener, emulsifier, thiab stabilizer nyob rau hauv ntau daim ntawv thov.
2. Cov yeeb yaj kiab zoo-tsim cov khoom: HPMC tuaj yeem ua cov pob tshab cov yeeb yaj kiab nrog cov tshuab zoo hluav taws xob muaj zog. Qhov no tso cai rau nws siv rau hauv kev tsim cov tshuaj ntsiav, pleev xim thiab lwm yam khoom.
3. Cov kev ua si siab: HPMC muaj cov khoom saum npoo av, tso cai rau nws siv los ua tus sawv cev ntub dej thiab cov neeg ntub dej.
4. Zoo thermal stability: HPMC yog qhov ruaj khov nyob rau hauv qhov kub thiab tuaj yeem siv rau hauv cov ntawv thov no.
5. Zoo adhesion rau ntau qhov chaw: HPMC tuaj yeem khi rau ntau qhov chaw, ua rau nws muaj txiaj ntsig hauv kev tsim cov nplaum thiab txheej.
Siv kev siv HPMC hauv ntau yam kev lag luam:
1. Tshuaj: HPMC tau siv dav hauv kev npaj ua haujlwm raws li cov phau ntawv, tsis sib haum xeeb, thiab viscosity buedulator. Nws muaj nyob hauv cov ntsiav tshuaj, tsiav tshuaj thiab cov kua ua kua.
2. Khoom noj: HPMC yog siv los ua cov tuab, stabilizer thiab emulsifier hauv cov zaub mov. Nws tuaj yeem siv tau hauv cov khoom xws li mis nyuj khov, yogurt thiab nyias noj khaub ncaws.
3. Cov tshuaj pleev ib ce: HPMC tau siv dav hauv cov tshuaj pleev ib ce ua cov tuab tuab, emulsifier, thiab zaj duab xis-ua tus neeg sawv cev. Nws tuaj yeem siv tau hauv cov khoom xws li cream, tshuaj thiab tsuaj zawv.
4. Kev Tsim Kho: HPMC yog cov khoom siv tseem ceeb hauv ntau cov khoom siv tsim kho xws li cov nplaum sib xyaw, cov khoom noj kom muaj pob noom. Nws ua raws li dej tuav tus neeg sawv cev, txhim kho kev ua haujlwm, thiab muab cov nplaum nplaum zoo dua thiab kev tswj kom txaus ntshai.
HPMC Kev Lag Luam Kev Lag Luam Kev Lag Luam HPMC:
1. Kiv qab los mus pw: Cov dej khaws nyiaj khaws cia HPMC yog qhov kev txiav txim siab tseem ceeb uas txiav txim siab nws qhov ua tau zoo thiab cov nplaum. Cov cuab yeej muaj kev lag luam siv cov nqi ntawm 80-100%.
2. Viscosity: viscosity yog tus tseem ceeb ntsuas hauv kev xaiv HPMC rau ntau yam kev siv. Kev lag luam kev lag luam siv sib piv rau viscosity li ntawm 5,000 rau 150,000 mpa.S.
3. MEHOXY GROUP Cov ntsiab lus: Cov pab pawg methoyl ntawm HPMC cuam tshuam rau nws solubility, viscosity thiab bioavailability. Cov Kev Lag Luam Kev Lag Luam rau mexoxy cov ntsiab lus yog nruab nrab ntawm 19% thiab 30%.
4. Hydroxypropyl cov ntsiab lus: lub ntsiab lus hydroxypropyl cuam tshuam rau solubility thiab viscosity ntawm HPMC. Kev lag luam kev lag luam siv rau hydroxypopyl cov ntsiab lus yog ntawm 4% thiab 12%.
HPMC yog cov polymer ntau yam nrog cov ntawv thov ntau cov ntawv thov. Nws cov khoom tshwj xeeb ua rau nws haum rau siv hauv cov chaw tshuaj, khoom noj, pleev tshuaj thiab kev tsim kho. Kev lag luam muag khoom siv rau ntau yam tsis pab xaiv cov qib kev tsim nyog HPMC rau ib daim ntawv thov tshwj xeeb.
