I-Hydroxylopenyl celtulose (HPMC) iyi-polymer yokwenziwa esetshenziswa kabanzi kwizicelo ezahlukahlukene ezinjengezidakamizwa, ukudla, izakhiwo kanye nezimonyo. Kuyinto etholwa yiselula futhi yakha i-glue coagulant ku-hydrophilic. Uhlobo oluhlanzekile lwe-HPMC luyimpuphu emhlophe engenamsoco echithwa emanzini ukwakha isixazululo esibonakalayo mucis.
Ukuphikisana kuka-HPMC inqubo yokwengeza noma ukuxuba izinto ezihlanzekile ezixubile kwezinye izinto zokushintsha izici zayo noma ukunciphisa izindleko zokukhiqiza. I-DoPIng ku-HPMC ingashintsha izakhiwo zomzimba, zamakhemikhali nezemishini ze-HPMC. I-HPMC isebenzisa ama-doping anchents amaningana, kufaka phakathi isitashi, amaprotheni amagilebhisi, i-cellulose, i-sucrose, i-glucose, i-carbonenethyllyl (cmc) ne-polyethylene ethylene (PEGC). Ukufakwa kwalaba bantu abadala kuzolimaza ikhwalithi, ukuphepha kanye nokusebenza kwempumelelo kwe-HPMC.
Kunokwehluka okuningana phakathi kwe-HPMC emsulwa kanye ne-Adulteration Cellulose:
1. Ukuhlanzeka: Umehluko omkhulu phakathi kwe-HPMC ehlanzekile kanye nokuphinga isendlalelo sabo ubumsulwa babo. I-HPMC ehlanzekile iyinto eyodwa ngaphandle kokungcola noma izengezo. Ngakolunye uhlangothi, ukuvuselisa isendlalelo kuqukethe ezinye izinto, ezingaba ezinye izinto ezithinta ngamabomu noma zingahlosile zithinta ikhwalithi yazo nezimpawu zazo.
2. Izici zomzimba: I-HPMC ehlanzekile uhlobo lwempuphu emhlophe, engenamsoco, incibilika emanzini ukwakha ikhambi elisobala le-viscous. Isiphikiso HPMC singaba nezimpawu ezihlukile zomzimba, ngokuya ngohlobo nenani le-ejenti eyengeziwe yokuphinga. Ukwemukelwa kungathinta i-solubity, ukubonakala nombala wezinto ezibonakalayo.
3. Izici zamakhemikhali: I-HPMC ehlanzekile iyi-polymer emsulwa kakhulu enezimpawu zamakhemikhali ezingaguquki. Ukwemukelwa kwezinye izinto zokwakha kungashintsha izici zamakhemikhali ze-HPMC, ezithinta imisebenzi yazo nokuphepha.
I-4. Ukuphepha: Ukusetshenziswa kokuphikisana kwe-celtule Isiphikiso HPMC singasebenzisana nezinye izinto ngendlela engalindeleki, edala izinkinga ezinkulu zempilo.
I-5. Izindleko: I-cellulose eguquliwe ishibhile kune-HPMC ehlanzekile, ngoba ukungezwa kwama-doping agents kuzonciphisa izindleko zokukhiqiza. Kodwa-ke, ukusetshenziswa kwesiphingi HPMC ekwenziweni kwezidakamizwa noma eminye imikhiqizo kungalimaza ikhwalithi kanye nokusebenza kahle komkhiqizo.
Konke kukho konke, i-HPMC ehlanzekile iyi-polymer emsulwa futhi ephephile, enezimpawu zamakhemikhali ezingaguquki nezingokomzimba. Ukuphikisana nezinye izinto kungashintsha izici ze-HPMC, ngaleyo ndlela kulimaze ikhwalithi nokuphepha komkhiqizo. Ngakho-ke, i-HPMC ehlanzekile kufanele isetshenziswe ekwenziweni kwezidakamizwa, ukudla, izakhiwo neminye imikhiqizo.
