I-HPMC Powder Makhiqikhi Isengezo se-HPMC ye-HPMC
Ukuchazwa Komkhiqizo
I-HPMC inempi yokuphola engenamphumo, engenambitha, engenamthwalo ye-computule ye-molecular kusuka ku-molecular ephezulu yeselula ngokusebenzisa uchungechunge lwamakhemikhali amakhemikhali futhi kufinyelelwe. Inokuqina, ukunamathela, ukusabalalisa, ukusabalalisa, ifilimu, imisiwe, ama-adsorption, i-gel kanye ne-protolive colloid yomsebenzi ongaphezulu futhi ugcine izakhiwo zomswakama ezisebenzayo.

Sebenza
Kuyinto esetshenziswayo, engasebenzi, i-viscoelastic polymer evame ukusetshenziswa ku-ophthalmology njenge-lubrication, noma njenge-excipient noma i-excipoint emithini yomlomo, evame ukutholakala ezinhlobonhlobo zezimpahla. Njengesengezo sokudla, i-hydroxypropylm methylcellulose ingasetshenziswa kulezi zindima ezilandelayo: i-emulsifier, i-nyouner, i-ejenti yokumiswa kanye nokufaka esikhundleni se-animal gelatin.
Isicelo
I-coating yisembozo esisetshenziswa ebusweni bezindonga, imvamisa ibizwa ngokuthi yi-substrate. Inhloso yokusebenzisa i-coating ingahle ihlobise, iyasebenza, noma yomibili. I-coating yengeza impahla enhle kakhulu efana nokudlalwa nokushayisana, umphumela wokuqina, njll.
