3. Kws ua paus chaw:
HPMC feem ntau siv los ua cov khoom siv txheej, cov nplaum thiab tuab rau cov ntsiav tshuaj hauv cov tshuaj. Nws muaj zoo biocompatibility thiab ruaj khov, tuaj yeem tswj hwm cov tshuaj tso tawm, thiab txhim kho kev ruaj ntseg thiab muaj txiaj ntsig zoo.
4. Kev lag luam khoom noj:
HPMC yog siv los ua cov tuab tuab, emulsifier thiab stabilizer nyob rau hauv kev lag luam khoom noj. Nws yog siv nyob rau hauv kev tsim cov mis nyuj khov, jelly, condiments thiab cov khoom noj siv mis, thiab lwm yam ntawm cov zaub mov thiab txuas lub txee lub neej ntawm cov zaub mov.
5. Cov Khoom Siv Saib Xyuas Tus Kheej:
HPMC feem ntau siv los ua cov tuab thiab ua yeeb yaj kiab-sib sau tus neeg sawv cev hauv cov khoom saib xyuas tus kheej. Nws yog siv nyob rau hauv kev tsim cov tshuaj zawv plaub hau, txias, tshuaj txhuam hniav thiab cov tshuaj txhuam hniav thiab lwm yam tuaj yeem txhim kho kev ruaj khov thiab siv cov khoom lag luam.
Methylcellulose (MC)
1. Lub Tsev Khoom Siv:
MC feem ntau yog siv los ua cov tuab dua, dej khaws cia thiab phau ntawv khaws cia hauv cov ntaub ntawv hauv tsev. Nws tuaj yeem txhim kho kev tsim kho ntawm kev tshuaj khib thiab tshuaj khib thiab ua kom muaj dej huv thiab dej ua kom zoo ntawm cov ntaub ntawv, yog li txhim kho kev tsim kho kev tsim kho tau zoo thiab zoo.
2. Kws ua daim teb:
MC siv los ua cov binder thiab ua txhaum rau cov ntsiav tshuaj hauv kev lag luam kws tshuaj. Nws tuaj yeem txhim kho cov tshuab zog thiab ruaj khov ntawm cov ntsiav tshuaj, tswj tso cov tshuaj tso tawm, txhim kho kev ua tau zoo ntawm cov tshuaj thiab neeg mob ua tsaug.
3. Kev lag luam khoom noj:
MC siv los ua cov tuab tuab, emulsifier thiab stabilizer nyob hauv kev lag luam khoom noj. Nws feem ntau siv nyob rau hauv kev tsim cov jelly, mis nyuj khov, dej haus thiab khoom siv mis, thiab tuaj yeem txhim kho cov qauv, thiab saj thiab muaj khoom noj thiab muaj khoom noj thiab ruaj khov ntawm cov zaub mov.
4. Textile thiab luam ntawv thiab Dyeing:
Nyob rau hauv textile thiab luam ntawv thiab dye zas kev lag luam, thiab txhim kho cov nplaum ntawm dyes thiab cov khoom sib txawv thaum lub sijhawm zas.
5. Cov Khoom Siv Saib Xyuas Tus Kheej:
MC feem ntau siv los ua tuab thiab stabilizer nyob rau hauv cov khoom lag luam saib xyuas tus kheej. Nws yog siv nyob rau hauv kev tsim cov tshuaj zawv plaub hau, txias, pleev tshuaj thiab cream, uas tuaj yeem txhim kho cov qauv thiab cov khoom lag luam thiab txhim kho cov nyhuv siv thiab kev paub.
Cov yam ntxwv zoo thiab cov txiaj ntsig
1. Kev nyab xeeb thiab biocompatibility:
MPMC thiab MC muaj kev nyab xeeb thiab biocompatibility, thiab haum rau cov teb uas muaj kev nyab xeeb txog kev nyab xeeb xws li khoom noj khoom haus, tshuaj thiab cov khoom lag luam tus kheej.
2. Versatility:
Ob lub cellulose no muaj ntau lub zog xws li thickening, kev ruaj khov, thiab zaj duab xis, uas tuaj yeem ntsib cov kev xav tau ntawm cov ntawv thov sib txawv.
3. Solubility thiab Stability:
HPMC thiab MC muaj cov khoom siv solubility zoo hauv dej thiab muaj peev xwm ua cov tshuaj zoo thiab ruaj khov, uas haum rau ntau yam tsim cov tshuab thiab cov txheej txheem tseev kom muaj.
HydroxyPropyyl methylulose (HPMC) thiab methylcellulose (MC), uas yog cov khoom siv cellulcellulose, tshuaj, khoom noj khoom haus, cov khoom lag luam. Nrog lawv cov kev ua tau zoo thiab versatility, lawv ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom lag luam zoo thiab ua tau zoo, txhim kho cov txheej txheem kev siv ntau dua thiab txhim kho cov neeg siv kev paub. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev nthuav dav txuas ntxiv, cov khoom siv no yuav txuas ntxiv ua cov ntawv thov ntau dua thiab kev lag luam tom ntej.
