Hydroxypropyl Methyl Cellulose yog dab tsi?

Hydroxypropyl Methyl Cellulose (HPMC) yog ib qho uas tsis yog-ionic cellulose ether uas feem ntau siv los ua cov thickener, binder, zaj duab xis-yav dhau los, thiab tshem tawm tus neeg sawv cev hauv ntau qhov kev lag luam. Nws yog muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag cell phab ntsa, los ntawm chemically hloov nws nrog methyl thiab hydroxypropyl pawg.

HPMC yog cov hmoov dawb mus rau dawb tsis muaj ntxhiab thiab tsis qab ntsev uas yog soluble hauv dej thiab ntau cov kuab tshuaj organic. Nws muaj kev hloov pauv siab, txhais tau hais tias nws muaj ntau ntawm hydroxypropyl thiab methyl pawg txuas nrog cov pob txha cellulose. Qhov no muab nws ntau yam khoom uas ua rau nws haum rau ntau yam kev siv.

Cov khoom ntawm Hydroxypropyl Methyl Cellulose

Thickening: HPMC cov khoom thickening zoo heev ua rau nws yog ib qho zoo tagnrho thickener rau ntau yam kev siv, nrog rau cov nplaum, coatings thiab cov khoom tu tus kheej. Nws tuaj yeem siv los ua kom viscosity, txhim khu kev ntxhib los mos, thiab txhim kho cov khoom ruaj khov.

Kev khi: HPMC yog ib qho khoom siv tau zoo, uas ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov, xws li hauv cov ntsiav tshuaj formulations, qhov twg nws yog siv los khi cov khoom xyaw nquag thiab cov khoom ntxiv ua ke.

Kev tsim cov yeeb yaj kiab: HPMC tuaj yeem tsim cov yeeb yaj kiab nrog lub zog zoo heev, dej tsis kam, thiab adhesion zog ..

Kev tuav dej: HPMC muaj cov khoom tuav dej zoo, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov uas tswj cov dej noo tseem ceeb, xws li hauv cov khoom siv cement.

Kev ncua: HPMC tuaj yeem tshem tawm cov khoom hauv cov kua nruab nrab, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov xws li cov xim, txheej thiab cov khoom siv tu tus kheej.

Kev siv ntawm Hydroxypropyl Methyl Cellulose

Kev tsim kho: HPMC tau siv dav hauv kev tsim kho kev lag luam raws li cov khoom siv ntxiv hauv cov khoom siv cement xws li mortar, grout, thiab pob zeb ..

Kev saib xyuas tus kheej: HPMC yog siv rau hauv cov khoom tu tus kheej xws li tshuaj zawv plaub hau, tshuaj pleev thiab tshuaj pleev ib ce ua cov thickener, ncua kev kawm ntawv thiab emulsifier.

Pharmaceuticals: HPMC yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug binder, dissolver, thiab filmformer nyob rau hauv cov ntsiav tshuaj formulations.

Khoom noj khoom haus: HPMC yog siv nyob rau hauv kev lag luam khoom noj khoom haus ua cov thickener, emulsifier thiab stabilizer nyob rau hauv ntau yam khoom noj khoom haus, xws li kua ntses, hnav khaub ncaws thiab khoom qab zib.

Xim thiab coatings: HPMC yog siv nyob rau hauv cov xim thiab coatings kev lag luam raws li ib tug thickener, binder, thiab filmformer.

Hauv cov ntsiab lus, Hydroxypropyl Methyl Cellulose yog ntau yam polymer nrog ntau yam kev siv hauv ntau yam kev lag luam..Nws cov khoom, xws li thickening, binding, tsim zaj duab xis, dej tuav thiab ncua kev kawm ntawv, ua rau nws muaj txiaj ntsig hauv ntau daim ntawv thov, suav nrog kev tsim kho, kev saib xyuas tus kheej. , tshuaj, khoom noj khoom haus, thiab xim thiab txheej.. Nrog rau kev thov rau cov ntaub ntawv ua tau zoo, HPMC yuav tsum txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam, tsav tsheb tshiab thiab kev nce qib.
