Hydroxypropyl methylcellulose (HPMC)yog cov khoom siv ntau yam polymer uas muaj nyob rau hauv qeb ntawm cellulose ether khoom. Vim nws lub cev zoo heev thiab tshuaj lom neeg, nws tau siv dav hauv kev tsim kho, tshuaj, khoom noj, tshuaj txhua hnub, thiab lwm yam.
1. Cov khoom siv yooj yim
Hydroxypropyl methylcellulose yog non-ionic dej-soluble polymer compound ua los ntawm ntuj cellulose los ntawm kev hloov tshuaj. Nws cov khoom tseem ceeb muaj xws li:
Cov dej solubility zoo heev: Nws tuaj yeem yaj hauv dej txias los tsim cov kua nplaum pob tshab.
Thickening nyhuv: Nws tuaj yeem ua kom cov viscosity ntawm cov kua lossis slurries.
Kev tuav dej: Nws muaj cov dej tuav zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv tsim los tiv thaiv kom qhuav sai thiab tawg.
Cov cuab yeej ua yeeb yaj kiab: Nws tuaj yeem tsim cov yeeb yaj kiab du thiab tawv ntawm qhov chaw nrog qee cov roj tsis kam thiab huab cua permeability.
Chemical stability: Nws yog acid thiab alkali resistant, mildew resistant, thiab ruaj khov nyob rau hauv ib tug dav pH ntau yam.
2. Cov chaw thov tseem ceeb
Kev tsim kho teb
AnxinCel®HPMC yog dav siv nyob rau hauv qhuav-siv mortar, putty hmoov, pobzeb nplaum thiab coatings nyob rau hauv kev tsim kho kev lag luam.
Cov tshuaj khib nyiab qhuav: HPMC txhim kho kev ua haujlwm, kev tsim kho thiab kev tuav dej ntawm cov mortar, ua kom yooj yim rau kev thov, thaum tiv thaiv kev tawg lossis lub zog poob tom qab ziab.
Pobzeb nplaum: Txhim kho adhesion thiab anti-slip zog, txhim kho kev tsim kho.
Putty hmoov: ncua sij hawm tsim kho, txhim kho smoothness thiab tawg kuj.
Latex xim: HPMC tuaj yeem siv los ua cov thickener thiab stabilizer los muab cov xim zoo nkauj txhuam thiab qib qib, thaum tiv thaiv cov xim sedimentation.
Pharmaceutical teb
Hauv kev lag luam kws tshuaj, HPMC feem ntau yog siv los ua cov khoom siv tshuaj thiab tau siv dav hauv cov ntsiav tshuaj, tshuaj ntsiav thiab cov tshuaj tiv thaiv kev tso tawm.
Cov ntsiav tshuaj: HPMC tuaj yeem siv los ua tus neeg sawv cev ua yeeb yaj kiab los muab cov ntsiav tshuaj zoo li qub thiab tiv thaiv cov khoom; nws kuj tseem siv tau ua cov nplaum, disintegrant thiab sustained-tso khoom.
Capsules: HPMC tuaj yeem hloov gelatin los tsim cov tshuaj ntsiav nyuaj, uas haum rau cov neeg tsis noj nqaij thiab cov neeg mob ua xua rau gelatin.
Sustained-tso npaj: Los ntawm cov nyhuv gelling ntawm HPMC, qhov tso tawm ntawm cov tshuaj tuaj yeem tswj tau meej, yog li txhim kho kev ua tau zoo.
Kev lag luam zaub mov
Hauv kev lag luam khoom noj khoom haus, HPMC yog siv los ua ib qho emulsifier, thickener thiab stabilizer, thiab feem ntau pom muaj nyob rau hauv cov khoom ci, dej haus thiab condiments.
Cov khoom ci: HPMC muab cov nyhuv moisturizing thiab shaping, txhim kho kev ua haujlwm ntawm khob noom cookie, thiab txhim kho saj thiab zoo ntawm cov khoom tiav.
Dej: Ua kom cov viscosity ntawm cov kua, txhim kho kev ncua kev ruaj ntseg, thiab tsis txhob stratification.
Cov neeg tsis noj nqaij hloov pauv: Hauv cov nqaij cog qoob loo lossis cov khoom siv mis nyuj, HPMC yog siv los ua cov thickener lossis emulsifier stabilizer los muab cov khoom noj zoo tshaj plaws thiab kev ntxhib los mos.
Cov tshuaj txhua hnub
Hauv kev saib xyuas tus kheej thiab cov khoom siv hauv tsev, AnxinCel®HPMC feem ntau yog siv los ua cov thickener, emulsifier stabilizer thiab zaj duab xis qub.
Detergents: Muab cov khoom lag luam nruab nrab viscosity thiab txhim kho cov khoom siv kev paub.
Cov khoom tu tawv nqaij: HPMC txhim kho moisturizing thiab kis tau rau hauv cov tshuaj pleev ib ce thiab tshuaj pleev.
Cov tshuaj txhuam hniav: Ua lub luag haujlwm hnyav thiab tshem tawm kom ntseeg tau qhov sib xws ntawm cov khoom xyaw mis.
3. Kev cia siab rau kev txhim kho
Nrog rau kev txhawb nqa ntawm cov tswv yim kev tiv thaiv ib puag ncig ntsuab thiab nthuav dav ntawm thaj chaw thov, qhov kev thov rau hydroxypropyl methylcellulose tseem nce ntxiv. Hauv kev tsim kho kev lag luam, HPMC, uas yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob txuag hluav taws xob thiab ib puag ncig tus phooj ywg, muaj kev lag luam dav dav; Hauv kev lag luam tshuaj thiab zaub mov, HPMC tau dhau los ua cov khoom tseem ceeb vim nws txoj kev nyab xeeb thiab ntau yam; nyob rau hauv cov khoom siv tshuaj txhua hnub, nws qhov kev ua tau zoo sib txawv muab kev ua tau zoo rau cov khoom lag luam tshiab.
Hydroxypropyl methylcellulose yog sivtau dhau los ua cov khoom siv tshuaj tseem ceeb hauv ntau qhov kev lag luam vim nws cov khoom zoo heev thiab kev siv dav. Nyob rau hauv lub neej yav tom ntej, nrog rau kev ua kom zoo dua ntawm cov txheej txheem ntau lawm thiab qhov tshwm sim tsis tu ncua ntawm cov kev xav tau tshiab, HPMC yuav ua kom pom nws tus nqi tshwj xeeb hauv ntau qhov chaw.
