Ukugcinwa kwamanzi: I-HPMC, njengesigcini samanzi, ingavimbela ukuhwamuka okukhulu nokulahlekelwa kwamanzi phakathi nenqubo yokwelapha. Lesi sakhiwo sokugcina amanzi siqinisekisa ukugeleza okwanele kukasimende futhi sithuthukisa amandla nokuqina kodaka. Ezimweni zokushisa okuphezulu, ukugcinwa kwamanzi kwe-HPMC kubaluleke kakhulu ukuvimbela udaka ekulahlekelweni kwamanzi ngokushesha, ngaleyo ndlela kuqinisekiswe ukusebenza kodaka.
Ukusebenza kahle: I-HPMC inomthelela omkhulu ekusebenzeni kodaka. Ngokudlulisa ukuthambisa, kunganciphisa ukungqubuzana phakathi kwezinhlayiya, kube lula ukukusebenzisa. Lokhu kusebenza okuthuthukisiwe kuqinisekisa inqubo yokwakha esebenza kahle.
Yehlisa ukushwabana nokuqhekeka: Ukuncipha kanye nokuqhekeka kuyizinselele ezivamile ekufakweni kodaka, okuholela ekuthintekeni kokuqina. I-HPMC yenza i-matrix eguquguqukayo odakeni, inciphisa ukucindezeleka kwangaphakathi futhi inciphise ukwenzeka kokuqhekeka kokuncipha, ngaleyo ndlela ithuthukise ukuqina kukonke kodaka.
Thuthukisa amandla okuguquguquka: I-HPMC inyusa amandla okuguquguquka kodaka ngokuqinisa i-matrix nokuthuthukisa ukuhlangana phakathi kwezinhlayiya. Lokhu kuzothuthukisa ikhono lokumelana nokucindezela kwangaphandle futhi kuqinisekise ukuzinza kwesakhiwo.
Izakhiwo ezishisayo: Ukwengezwa kwe-HPMC kungakhiqiza impahla elula ngokunciphisa isisindo ngo-11.76%. Le porosity ephezulu isiza ngokufaka ukushisa okushisayo futhi inganciphisa ukuqhutshwa kwezinto ngokufika ku-30% ngenkathi igcina ukushisa okungaguquki okungaba ngu-49W uma ingaphansi kokushisa okufanayo. Ukumelana nokudlulisa ukushisa ngephaneli kuyahlukahluka ngenani le-HPMC elingeziwe, futhi inani eliphakeme kakhulu lezithasiselo liphumela ekukhuphukeni okungama-32.6% kokumelana nokushisa uma kuqhathaniswa nengxube yereferensi.
Ukungena komoya: I-HPMC inganciphisa amandla angaphezulu esixazululo esinamanzi ngenxa yokuba khona kwamaqembu e-alkyl, yandise okuqukethwe kwegesi ekuhlakazweni, futhi ukuqina kwefilimu yebhamuza kuphakeme kunamabhamuza amanzi ahlanzekile, okwenza kube nzima ukukhipha. . Lokhu kufakwa komoya kungase kunciphise amandla aguquguqukayo kanye namandla acindezelayo wezibonelo zodaka lukasimende, kodwa futhi kuzokwandisa ukugcinwa kwamanzi kodaka.
Umthelela wezinga lokushisa ku-gelation: Ucwaningo lubonise ukuthi idigri yokuvuvukala elinganayo ye-HPMC hydrogel yehla ngokunyuka kwezinga lokushisa. Izinga lokushisa linomthelela omkhulu ekuziphatheni kokuvuvukala kwe-HPMC hydrogel, okungase kuthinte izakhiwo zayo zodaka emazingeni okushisa ahlukene.
Umthelela wezinga lokushisa nokugxila kwe-polymer emandleni okumanzisa: Izinguquko kumazinga okushisa kanye nokugxila kwe-HPMC kuthinta ukushuba okuguquguqukayo kwendawo kanye nekhono lokumanzisa lesisombululo sayo esinamanzi. Njengoba ukugxila kwe-HPMC kukhuphuka, inani eliguqukayo le-engeli yokuxhumana lesixazululo nalo liyakhuphuka, ngaleyo ndlela kunciphisa ukuziphatha okusakazekayo kwendawo yethebhulethi ye-Avicel.
I-HPMC inomphumela obalulekile ekusebenzeni kodaka emazingeni okushisa ahlukene, futhi ingathuthukisa ukugcinwa kwamanzi kodaka, ithuthukise ukusebenza kahle, ithuthukise ukumelana nokuqhekeka, ithuthukise amandla okubopha, ithuthukise ukuqina, inciphise ukushwabana nokuqhekeka, ithuthukise ukumelana namanzi nokungagxili, ithuthukise iqhwa. -ncibilikisa ukumelana, futhi uthuthukise amandla esibopho esiqinile. Lezi zici zenza i-HPMC ibe isithasiselo esibalulekile sokuthuthukisa ukuqina kodaka.
