Tablet cov phau ntawv: HPMC ua raws li cov ntsiav tshuaj siv tau zoo thiab pab tsim cov ntsiav tshuaj nrog cov khoom siv zoo thiab cov khoom siv hluav taws xob zoo thiab cov khoom siv tsis sib xws.
Tus neeg sawv cev raug tshem tawm: Hauv cov ntaub ntawv ua kua, HPMC ua raws li kev ncua tus neeg sawv cev, tiv thaiv kev faib tawm ntawm cov tshuaj.
B. Ophthalmic Daim Ntawv Thov:
Viscosity Monifier: HPMC yog siv los kho lub viscosity ntawm qhov muag tso zis kom muab lub sijhawm tsim nyog
Zaj duab xis tsim: siv los ua cov ncauj qhov ntswg lossis cov ntxig rau cov tshuaj tso tawm hauv lub qhov muag.
C. Cov ntsiab lus npaj:
GEL Tsim: HPMC yog siv los npaj cov kua pleev cov kua nplaum uas muab ib qho du, tsis muaj roj ua qauv thiab txhim kho kev ua raws li kev ua raws.
Daim tawv nqaij Cov nplaum nplaum: Hauv kev xa tshuaj Transdermal
D. Biodegradable immants:
Cov Khoom Siv Scaffold: HPMC yog siv los tsim cov kev cog lus biodegradable uas tswj cov tshuaj tso tawm hauv lub cev, tshem tawm qhov xav tau kev tshem tawm kev phais mob.
2. Kev lag luam kev tsim kho
A. Cov nplais nplaum:
Thickener: HPMC yog siv los ua cov tuab tuab hauv cov nplais nplaum kom muab cov khoom siv uas yuav tsum tau ua ke rau kev thov kom yooj yim.
Dej khaws cia: nws txhim kho cov dej tuav ntawm cov nplaum, tiv thaiv nws los ntawm kom qhuav nrawm nrawm thiab ua kom pom kev zoo sai thiab ua kom zoo dua.
B. CAENT CUG:
Kev Ua Haujlwm: HPMC ua raws li kev ntseeg rheology kom tiv thaiv kev cais thiab txhim kho kev sib koom tes, yog li kev txhim kho cov haujlwm ntawm cov cement-raws li Maas-raws li Maas-raws li Maas-raws li Fesss.
Dej khaws cia: zoo ib yam li cov nplais nplaum, nws pab khaws cov dej noo hauv kev sib xyaw kom zoo, tso cai rau kev txhim kho kom zoo thiab kev ua tau zoo.
3. Kev lag luam khoom noj khoom haus
A. A. Cov Khoom Noj Ntxiv:
Thickeners thiab stabilizers: HPMC yog siv los ua cov tuab thiab stabilizer nyob rau ntau yam khoom noj khoom haus, xws li cov kua zaub, hnav khaub ncaws, hnav khaub ncaws.
Cov roj muaj rog: hauv cov zaub mov tsis muaj rog lossis rog-dawb, HPMC tuaj yeem siv los ua cov roj hloov kom txhim kho kev ntxhib los mos thiab cov ncauj lus.
4. Kev lag luam tshuaj pleev ib ce
A. Cov khoom siv saib xyuas tus kheej:
Viscosity tswj: HPMC yog siv nyob rau hauv cov tshuaj pleev ib ce xws li lotions thiab cream kom tswj viscosity thiab txhim kho tag nrho cov kev ntxhib.
Zaj duab xis Talers: Pab ua zaj mauv vim hauv cov khoom tu plaub hau, muab cov txheej tiv thaiv.
5. Lwm cov ntawv thov
A. luam tawm number case:
Thickener: HPMC yog siv los ua cov tuab tuab hauv cov kua dej hauv dej los pab ua kom tiav qhov xav tau zoo thiab ruaj khov ntawm number case.
B. Cov khoom lag luam nplaum:
Txhim kho viscosity: Hauv cov qauv nplaum: HPMC tuaj yeem raug ntxiv rau txhim kho viscance viscosity thiab txhim kho cov khoom sib raug zoo.
5. Hauv kev xaus
HPMC muaj ntau txoj kev lag luam ntawm HPMC hauv ntau yam kev lag luam qhia txog nws cov versatility thiab kev coj zoo. Nws siv hauv cov kws tshuaj, kev tsim kho, khoom noj, cov tshuaj pleev ib ce thiab lwm thaj chaw uas pom tias muaj peev xwm ua ke ntawm cov khoom, suav nrog cov muaj peev xwm ua ke, txo cov khoom muaj peev xwm, thickening cov khoom thiab ruaj khov. Raws li thev naus laus zis thiab kev tshawb fawb ua ntej, HPMC ua ntej lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom lag luam tshiab thiab cov qauv hauv cov khoom sib txawv.
