HydroxyPropyyl methylcellulose (hypromellose)

HydroxyPropyyl methylcellueculose (HPMC) kuj nquag paub los ntawm lub hom npe Hypromellose. Hypromellose yog lub npe tsis yog tus tswv siv los txhais cov tib lub polymer hauv cov tshuaj thiab cov ntsiab lus kho mob. Kev siv ntawm lub sij hawm "hypromellose" yog ib txwm nyob hauv kev lag luam kws tshuaj thiab yog qhov tseem ceeb nrog HPMC.

Nov yog qee cov ntsiab lus tseem ceeb hais txog hydroxypropyl methylulose (hypromellose):

1. Tus qauv tshuaj:
   • HPMC yog ib nrab hluavtaws polymer muab tau los ntawm cellulose, lub ntuj muaj zog pom hauv tsob ntoo cell.
   • Nws yog tsim los ntawm kev siv cellulation cellulose los ntawm kev sib ntxiv ntawm hydroxyprropyl thiab methyl pawg.
2. Cov Ntawv Thov:
   • Kws Tshuaj: Hypromellose tau siv dav hauv kev lag luam kws tshuaj yog kev zam. Nws yog pom nyob rau hauv ntau cov ntawv ntawm cov ntawv hauv qhov ncauj, suav cov ntsiav tshuaj, tsiav tshuaj, thiab raug ncua. Hypromellose pab ua cov phau ntawv, tsis sib xws, viscosity concififier, thiab zaj duab xis yav tas los.
   • Kev lag luam tsim kev tsim kho: Siv cov khoom lag luam xws li cov nplaum nplaum, cov neeg nplua nuj, thiab cov khoom siv gypsum. Txhim khu kev ua haujlwm, dej ua haujlwm, thiab cov nplaum.
   • Kev Lag Luam Khoom Noj: Ua haujlwm raws li cov tuab ua cov tuab, stabilizer, thiab emulsifier hauv cov khoom noj khoom haus, ua rau muaj kev ntxhib los mos thiab ruaj khov.
   • Cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej: pom nyob hauv cov tshuaj pleev, cream, thiab tshuaj pleev rau nws cov cua sov thiab ruaj khov.
3. Lub cev lub cev:
   • Feem ntau ib tug dawb rau me ntsis off-dawb hmoov nrog ib tug fibrous lossis granular kev ntxhib los mos.
   • Odorless thiab tasteless.
   • Soluble hauv dej, sib sau cov ntshiab thiab tsis muaj kob.
4. Qib ntawm hloov chaw:
   • Cov qib sib txawv ntawm Hypromellose tej zaum yuav muaj sib txawv qib ntawm kev hloov pauv, cuam tshuam cov khoom zoo li solubility thiab dej khaws cia.
5. Kev Nyab Xeeb:
   • Feem ntau suav hais tias muaj kev nyab xeeb rau siv hauv cov tshuaj, khoom noj khoom haus, thiab cov khoom lag luam saib xyuas tus kheej thaum siv raws li cov lus qhia.
   • Kev txiav txim kev nyab xeeb yuav nyob ntawm cov xwm txheej xws li cov qib hloov pauv thiab daim ntawv thov tshwj xeeb.

Nws yog ib qho tseem ceeb kom nco ntsoov tias thaum sib tham HPMC hauv cov ntsiab lus ntawm cov tshuaj, lo lus "hypromellose" feem ntau siv. Kev siv ntawm ob lub sij hawm siv tau, thiab lawv xa mus rau tib lub polymer nrog hydroxypropyl thiab methyl hloov ntawm lub cell caj qaum.
