Hypromellose ma yahay mid dabiici ah?

Hypromellose, oo sidoo kale loo yaqaan hydroxypropyl methylcellulose (HPMC), waa polymer semisynthetic ah oo laga soo qaatay cellulose, polymer dabiici ah oo laga helo gidaarada unugyada dhirta. Inkasta oo cellulose lafteedu ay tahay mid dabiici ah, habka wax ka beddelka si loo abuuro hypromellose waxay ku lug leedahay falcelinta kiimikaad, samaynta hypromellose xarun semisynthetic ah.

Soo saarista hypromellose waxay ku lug leedahay daaweynta cellulose leh propylene oxide iyo methyl chloride si loogu soo bandhigo hydroxypropyl iyo kooxaha methyl ee lafta dhabarka cellulose. Wax ka beddelkaani wuxuu wax ka beddelaa sifooyinka cellulose, isagoo siinaya hypromellose sifooyinkeeda gaarka ah sida milanka biyaha, awoodda sameynta filimada, iyo viscosity.

Inkasta oo hypromellose aan si toos ah looga helin dabeecadda, waxay ka timid ilo dabiici ah (cellulose) waxaana loo tixgeliyaa inay tahay mid noolaha iyo biodegradable. Waxaa si weyn loogu isticmaalaa dawooyinka, alaabta cuntada, waxyaalaha la isku qurxiyo, iyo codsiyada warshadaha kala duwan ay sabab u tahay badbaadada, kala duwanaansho, iyo shaqayntiisa.

Marka la soo koobo, halka hypromellose uu yahay xarun semisynthetic ah, asal ahaan ka soo jeeda cellulose, polymer-ka dabiiciga ah, iyo biocompatibility waxay ka dhigaysaa qayb si ballaaran loo aqbalo codsiyada kala duwan.
