Cov dej tuav ntawm hypromellose HPMC cov khoom yog feem ntau cuam tshuam los ntawm cov hauv qab no: 1. Cellulose ether HPMC homogeneously reacted nrog HPMC, methoxy, hydroxypropyl homogeneously faib, siab retention tus nqi.2. Cellulose ether HPMC thermogel kub, thermogel kub, siab dej tuav tus nqi, ntawm qhov tsis tooj, tsis tshua muaj dej tuav tus nqi.3. Thaum lub viscosity ntawm cellulose ether HPMC nce, cov dej tuav tus nqi kuj nce, thiab thaum lub viscosity mus txog ib tug tej degree, cov dej tuav tus nqi nce maj mam.Plaub.Qhov ntau ntawm cellulose ether HPMC tau ntxiv, qhov siab dua cov dej tuav tau, thiab qhov zoo ntawm cov dej tuav tau zoo dua.Nyob rau hauv thaj tsam ntawm 0.25-0.6%, cov dej tuav tau nce sai nrog qhov nce ntawm qhov sib ntxiv.
