ntsib thawj zaug
HydroxyPropyyl Metylcellulose (HPMC) tau dhau los ua cov khoom siv nrov tau vim nws cov kev siv ntau yam. HPMC yog muab tau los ntawm kev cog ntoo ntuj thiab tuaj yeem ua cov khoom lag luam los tsim cov khoom siv ntau yam nrog cov khoom sib txawv. Hauv Chaw Muaj Khoom, HPMC tau siv dav hauv cov zaub mov thiab cov tshuaj, cov khoom siv tsim kho, thiab cov khoom lag luam saib xyuas tus kheej. Kab lus no yuav qhia txog cov yam ntxwv ntawm HPMC thiab nws cov ntawv thov.
Cov yam ntxwv ntawm Kev Lag Luam HPMC
1. Dej Solubility
Muaj HPMC yog ntau soluble hauv dej, ib qho cuab yeej uas ua rau nws zoo heev thickener. Hauv kev lag luam khoom noj khoom haus, HPMC yog siv los ua kom tuab cov kua zaub, cov kua ntses thiab cov pob zeb. Hauv cov tshuaj pleev ib ce, nws yog siv rau hauv cov cream thiab cov tshuaj pleev kom muab cov qauv du.
2. Viscosity
Lub viscos ntawm HPMC kev daws teeb meem tuaj yeem tswj hwm los ntawm kev kho cov concentration ntawm cov khoom siv. Lub visccs siab HPMC yog siv hauv cov khoom noj khoom haus kom muab cov ntaub ntawv tuab si, cov tshuaj nplaum, thaum muaj cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej.
3. Kev ruaj khov
HPMC yog cov khoom ruaj khov uas tuaj yeem tiv taus ntau qhov chaw kub thiab phua. Muaj HPMC yog siv hauv cov khoom siv tsim kho xws li pob zeb ua kom zoo lawv qhov ruaj khov thiab kev ua haujlwm ntev. HPMC kuj tseem siv tau los ua cov stabilizer rau emulsions thiab ncua hauv kev lag luam tshuaj.
4. Biocompatibility
Kev lag luam HPM yog biocompible, lub ntsiab lus nws tsis yog tshuaj lom lossis tsis muaj kev phom sij rau cov nqaij. Cov cuab yeej no ua rau nws muaj kev nyab xeeb rau siv ntau daim ntawv thov khomob, xws li cov tshuaj siv tshuaj. HPMC kuj tseem siv rau hauv cov kev daws teeb meem ophthalmic los nce viscosity ntawm cov kua thiab muab kev nyiam, ntuj xav rau tus neeg mob.
Kev Siv HPMC
1. Kev lag luam khoom noj khoom haus
HPMC tau dav siv hauv kev lag luam khoom noj ua cov tuab thiab stabilizer. Nws yog siv nyob rau hauv cov khoom xws li mis nyuj khov, mis nyuj thiab cov zaub mov tiav. HPMC kuj tseem siv los txhim kho cov qauv ntawm cov khoom siv gluten-pub dawb, muab ib qho kev ntxhib los mos ntau dua thiab saj. Raws li cov neeg tsis noj nqaij khoom, HPMC hloov cov tsiaj tsiaj cov kua roj gelatin hauv ntau daim ntawv thov.
2. Kev lag luam kev lag luam
Hauv kev lag luam kws tshuaj, HPMC yog siv los ua phau ntawv, cov neeg sawv cev tsis sib xws thiab zaj duab xis txheej tus neeg sawv cev rau cov ntsiav tshuaj. Nws tseem raug siv los ua cov gelatin hloov hauv cov tsiav tshuaj thiab tuaj yeem siv hauv cov neeg tsis noj nqaij capsules. HPMC yog siv nyob rau hauv kev tswj-tso tawm los maj mam tso cov tshuaj rau hauv lub cev. Ib qho ntxiv, HPMC yog siv los ua cov tuab thiab roj nplua nyeem hauv ophthalmic daws.
3. Kev saib xyuas tus kheej thiab kev lag luam tshuaj pleev ib ce
Industrial HPMC feem ntau yog siv los ua cov tuab dua, emulsifier thiab stabilizer rau kev saib xyuas tus kheej thiab tshuaj pleev ib ce. HPMC yog siv nyob rau hauv cov khoom tu plaub hau kom muab ib qho kev nyiam thiab ci. Hauv kev tu tawv nqaij, nws yog siv los muab kev co, txhim kho kev ntxhib los mos, thiab siv tshuaj kom ruaj khov.
4. Kev lag luam kev tsim kho
HPMC yog siv rau hauv kev tsim kho kev tsim kho nyob rau hauv kev lag luam kev tsim kho raws li dej tuav tus neeg sawv cev, cov tuab yaj ntaub, nplaum thiab stabilizer. Hauv kev ua vaj tse, nws txhim kho lub zog ua haujlwm, txo cov kab nrib pleb thiab txhim kho kom ua haujlwm ruaj khov. Raws li cov dej tuav tus neeg sawv cev, HPMC pab khaws cov dej noo thiab tiv thaiv evaporation thaum kho.
Hauv kev xaus
HydroxyPropyyl methylulose yog ib qho khoom tseem ceeb hauv cov chaw muaj kev lag luam thiab muaj ntau cov ntawv thov. Nws cov khoom siv tshwj xeeb, suav nrog cov dej so, viscosity, ruaj khov thiab biocompatibility, ua rau nws muaj ntau yam haum rau kev lag luam sib txawv. Txawm hais tias nyob rau hauv cov zaub mov, tshuaj, tshuaj pleev ib ce lossis kev tsim kho kom zoo nkauj, HPMC yog cov khoom muaj nqis uas tuaj yeem muab cov teeb meem nyuaj.
