Ingabe i-hypromellose yemvelo?
I-Hypromellose, eyaziwa nangokuthi i-hydroxypropyl methylcellulose (HPMC), iyi-polymer e-semisynthetic etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Nakuba i-cellulose ngokwayo ingokwemvelo, inqubo yokuyishintsha ukuze yakhe i-hypromellose ihilela ukusabela kwamakhemikhali, okwenza i-hypromellose ibe inhlanganisela ye-semisynthetic.
Ukukhiqizwa kwe-hypromellose kubandakanya ukwelapha i-cellulose nge-propylene oxide ne-methyl chloride ukwethula i-hydroxypropyl namaqembu e-methyl kumgogodla we-cellulose. Lokhu kuguqulwa kushintsha izakhiwo ze-cellulose, kunikeza i-hypromellose izici zayo eziyingqayizivele njengokuncibilika kwamanzi, ikhono lokwenza ifilimu, kanye ne-viscosity.
Nakuba i-hypromellose ingatholakali ngokuqondile emvelweni, itholakala emthonjeni wemvelo (cellulose) futhi ibhekwa njenge-biocompatible kanye ne-biodegradable. Isetshenziswa kakhulu kwezemithi, emikhiqizweni yokudla, kwezimonyo, nasezinhlelweni ezahlukahlukene zezimboni ngenxa yokuphepha kwayo, ukuguquguquka, nokusebenza kwayo.
Kafushane, ngenkathi i-hypromellose iyinhlanganisela ye-semisynthetic, umsuka wayo ovela ku-cellulose, i-polymer yemvelo, kanye nokuhambisana kwayo kwe-biocompatibility kuyenza ibe isithako esamukelwe kabanzi ekusetshenzisweni okuhlukahlukene.
