IHydroxylopenyl cellulose (HPMC) iyi-polymer yokwenziwa esetshenziswa kabanzi ezinhlelweni ezahlukahlukene ezifana nezidakamizwa, ukudla, izakhiwo nezimonyo. Iphuma ku-cellulose futhi yenza i-glue coagulant ku-hydrophilic. Ifomu elihlanzekile le-HPMC liyimpushana emhlophe enganambitheki encibilika emanzini ukuze yakhe isixazululo samafinyila asobala.
Ukuphinga kwe-HPMC kuyinqubo yokwengeza noma exutshwe izinto ezihlanzekile kwezinye izinto ukuze uguqule izici zayo noma unciphise izindleko zokukhiqiza. I-doping ku-HPMC ingashintsha izakhiwo ezingokomzimba, zamakhemikhali nezomshini ze-HPMC. I-HPMC isebenzisa ama-doping agents amaningana avamile, okuhlanganisa isitashi, amaprotheni amagilebhisi, i-cellulose, i-sucrose, i-glucose, i-carboxymethyl cellulose sodium (CMC) ne-polyethylene ethylene (PEG). Ukwengezwa kwalaba bantu abadala kuzolimaza ikhwalithi, ukuphepha nokusebenza ngempumelelo kwe-HPMC.
Kunomehluko eminingana phakathi kwe-HPMC emsulwa kanye ne-cellulose yokuphinga:
1. Ukuhlanzeka: Umehluko omkhulu phakathi kwe-HPMC emsulwa kanye neselulosi yokuphinga ubumsulwa bazo. I-HPMC ehlanzekile yinto eyodwa engenakho ukungcola noma izithasiselo. Ngakolunye uhlangothi, i-cellulose yokuphinga iqukethe ezinye izinto, okungenzeka kube ezinye izinto ezithinta ngamabomu noma ngokungenhloso ikhwalithi nezici zazo.
2. Izici zomzimba: I-HPMC ehlanzekile iwuhlobo lwempushana emhlophe, engenambimbi, encibilika emanzini ukuze yakhe isixazululo se-viscous esisobala. I-HPMC yokuphinga ingase ibe nezici zomzimba ezihlukene, kuye ngohlobo nenani le-ejenti yokuphinga eyengeziwe. Ukungena kungase kuthinte ukunyibilika, i-viscosity nombala wento.
3. Izici zamakhemikhali: I-HPMC ehlanzekile iyi-polymer ehlanzekile kakhulu enezici zamakhemikhali ezingaguquki. Ukwamukelwa kwezinye izinto kungashintsha izici zamakhemikhali ze-HPMC, ezithinta imisebenzi yayo nokuphepha.
4. Ukuphepha: Ukusetshenziswa kwe-cellulose ephingayo kungase kube yingozi empilweni ngoba lokhu konakala kungase kube nezinto ezinobuthi noma eziyingozi. I-HPMC yokuphinga ingase futhi ihlanganyele nezinye izinto ngendlela engalindelekile, edala izinkinga ezinkulu zempilo.
5. Izindleko: I-cellulose eguquliwe ishibhile kune-HPMC ehlanzekile, ngoba ukungezwa kwama-doping agents kuzonciphisa izindleko zokukhiqiza. Nokho, ukusetshenziswa kokuphinga kwe-HPMC ekwenzeni izidakamizwa noma eminye imikhiqizo kungalimaza ikhwalithi nokusebenza komkhiqizo.
Sekukonke, i-HPMC emsulwa iyipolymer emsulwa kakhulu futhi ephephile, enezici ezingaguquki zamakhemikhali nezomzimba. Ukuphinga nezinye izinto kungashintsha izici ze-HPMC, ngaleyo ndlela kulimaze ikhwalithi nokuphepha komkhiqizo. Ngakho-ke, i-HPMC emsulwa kufanele isetshenziswe ekwenzeni izidakamizwa, ukudla, izakhiwo kanye neminye imikhiqizo.
