HPMC E3, E5, E6, E15, E50, E4m, K4m, K100, K100m rau Pharma Qib

HPMC, los yog Hydroxypropyl Methylcellulose, yog ib qho khoom siv feem ntau hauv kev lag luam kws tshuaj. Cov qib sib txawv ntawm HPMC hais txog qhov sib txawv ntawm qhov hnyav molecular thiab qib ntawm kev hloov pauv ntawm cov polymer, uas tuaj yeem cuam tshuam rau nws cov khoom thiab kev ua tau zoo hauv kev siv tshuaj sib txawv.

Nov yog cov ntsiab lus luv luv ntawm qee cov qib HPMC thiab lawv cov khoom:

• HPMC E3: Tsawg molecular hnyav HPMC nrog viscosity ntawm 2.4-3.6 cps. Nws yog feem ntau siv los ua ib daim ntawv khi, disintegrant, thiab thickener hauv cov ntsiav tshuaj thiab tshuaj ntsiav.
• HPMC E5: Tsawg molecular hnyav HPMC nrog viscosity ntawm 4-6 cps. Nws feem ntau yog siv los ua cov ntawv khi thiab matrix qub hauv cov ntsiav tshuaj uas tau tso tawm thiab ua cov thickener hauv kev ncua.
• HPMC E6: Tsawg molecular hnyav HPMC nrog viscosity ntawm 4.8-7.2 cps. Nws yog feem ntau siv los ua cov ntawv khi thiab matrix qub hauv cov ntsiav tshuaj uas tau tso tawm thiab ua cov thickener hauv kev ncua.
• HPMC E15: Tsawg molecular hnyav HPMC nrog viscosity ntawm 12-18 cps. Nws yog feem ntau siv los ua ib daim ntawv khi, matrix qub, thiab tus neeg sawv cev tso tawm hauv cov ntsiav tshuaj thiab tshuaj ntsiav.
• HPMC E50: Tsawg molecular hnyav HPMC nrog viscosity ntawm 40-60 cps. Nws yog feem ntau yog siv los ua ib tug matrix qub thiab sustained-tso tus neeg saib xyuas hauv cov ntsiav tshuaj thiab tshuaj ntsiav.
• HPMC E4m: siab molecular hnyav HPMC nrog viscosity ntawm 3,000-5,600 cps. Nws yog feem ntau yog siv los ua ib tug matrix qub thiab sustained-tso tus neeg saib xyuas hauv cov ntsiav tshuaj thiab tshuaj ntsiav.
• HPMC K4m: siab molecular hnyav HPMC nrog viscosity ntawm 3,000-5,600 cps. Nws yog feem ntau yog siv los ua ib tug matrix qub thiab sustained-tso tus neeg saib xyuas hauv cov ntsiav tshuaj thiab tshuaj ntsiav.
• HPMC K100: Tsawg molecular hnyav HPMC nrog viscosity ntawm 80-120 cps. Nws yog feem ntau yog siv los ua ib tug matrix qub thiab sustained-tso tus neeg saib xyuas hauv cov ntsiav tshuaj thiab tshuaj ntsiav.
• HPMC K100m: siab molecular hnyav HPMC nrog viscosity ntawm 80,000-120,000 cps. Nws yog feem ntau yog siv los ua ib tug matrix qub thiab sustained-tso tus neeg saib xyuas hauv cov ntsiav tshuaj thiab tshuaj ntsiav.

Qhov kev xaiv ntawm qib HPMC yuav nyob ntawm seb cov qauv tsim tshwj xeeb thiab cov yam ntxwv ua haujlwm xav tau rau cov khoom siv tshuaj tshwj xeeb.
