(Hydroxypropyl) methyl cellulose, feem ntau yog hu ua hypromellose lossis hpmc, yog ib nrab hluavtaws polymer muab tau los ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo phab ntsa. Lub npe siv tshuaj lom tau hais txog kev sib ntxiv ntawm hydroxypropyl thiab methyl pawg mus rau cov txheej txheem tshuaj lom neeg. Qhov kev hloov pauv no tau txhim kho cov khoom polymer, ua rau nws muaj txiaj ntsig hauv kev lag luam ntau yam. Ntawm no yog ib qho ntsiab lus qhia:

1. Tus qauv tshuaj:
   • Lo lus "(hydroxypropyl) methyl cellulose" qhia meej tias muaj cov pab pawg methylropyl thiab methyl pawg hauv cov qauv tshuaj ntawm cellulose.
   • Qhov sib ntxiv ntawm cov pab pawg no hloov kho lub cev thiab tshuaj ntawm cellulose, ua rau muaj cov polymer hloov.
2. Lub cev lub cev:
   • Feem ntau, hypromellose yog ib tug dawb rau me ntsis off-dawb hmoov nrog ib tug fibrous lossis granular kev ntxhib los mos.
   • Nws tsis muaj ntxhiab thiab tsis tau, pab txhawb nws txoj kev haum rau kev siv hauv cov ntawv thov sib txawv.
   • Cov polymer yog soluble hauv dej, sib sau ua kom muaj qhov tseeb thiab tsis muaj xim.
3. Cov Ntawv Thov:
   • Kws Tshuaj: Hypromellose tau siv dav hauv kev lag luam kws tshuaj uas muaj kev zam nyob hauv ntau cov ntaub ntawv tshuaj. Nws ua cov yeeb yam xws li binder, disintterrant, thiab viscosity concifiier hauv ntsiav tshuaj, tsiav tshuaj, thiab kev ncua.
   • Kev lag luam tsim kev tsim kho: Hauv cov ntaub ntawv tsim kho, hypromellose siv tau hauv cov khoom lag luam xws li cov khoom lag luam ntses, cov ntaub ntawv nplua nuj, thiab cov khoom lag luam gypsum. Nws txhim kho kev ua haujlwm, dej tuav, thiab cov nplaum.
   • Kev Lag Luam Khoom Noj: Nws ua haujlwm ua cov tuab, stabilizer, thiab emulsifier hauv kev lag luam khoom noj, txhim kho cov qauv khoom noj thiab muaj kev ruaj khov ntawm cov khoom noj khoom haus.
   • Cov khoom lag luam ntawm tus kheej: Hypromellose pom nyob hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej xws li, thiab tshuaj pleev vim nws cov khoom siv khov kho thiab ruaj khov.
4. Ua haujlwm:
   • Zaj duab xis: Hypromellose muaj peev xwm ua cov yeeb yaj kiab ua yeeb yam, uas yog tshwj xeeb tshaj plaws hauv cov ntaub ntawv thov tshuaj xws li ntsiav tshuaj txheej ntsiav.
   • Viscosity Transpification: Nws tuaj yeem hloov kho lub viscosity ntawm cov kev daws teeb meem, muab kev tswj hwm cov khoom ntawm cov qauv ntawm cov qauv.
   • Dej khaws cia: hauv cov ntaub ntawv uas tsim kho, hypromellose pab khaws dej, txhim kho kev ua haujlwm kom qhuav thiab tiv thaiv kev ua haujlwm ntxov.
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.

Hauv cov ntsiab lus, (hydroxyproyl) Nws cov tshuaj hloov kho tau txhim kho nws solubility thiab imparts tshwj xeeb kev ua haujlwm, ua rau nws muaj txiaj ntsig zoo hauv ntau yam khoom lag luam sib txawv.
