Ukugcinwa kwamanzi: I-HPMC, njenge-ejenti yokugcina amanzi, ingavimbela ukuhwamuka okukhulu nokulahlekelwa kwamanzi phakathi nenqubo yokwelapha. Ukushintsha kwezinga lokushisa kuthinta kakhulu ukugcinwa kwamanzi kwe-HPMC. Uma izinga lokushisa liphezulu, kuba kubi kakhulu ukugcinwa kwamanzi. Uma izinga lokushisa lodaka lidlula ama-40°C, ukugcinwa kwamanzi kwe-HPMC kuzoba kubi, okuzophazamisa kabi ukusebenza kodaka. Ngakho-ke, ekwakhiweni kwehlobo lokushisa eliphezulu, ukuze kuzuzwe umphumela wokugcina amanzi, imikhiqizo yekhwalithi ephezulu ye-HPMC idinga ukungezwa ngamanani anele ngokuya ngefomula. Uma kungenjalo, izinkinga zekhwalithi ezifana nokunganele kwe-hydration, amandla ancishisiwe, ukuqhekeka, ukugoba, nokuchithwa okubangelwa ukomiswa ngokweqile kuzokwenzeka. umbuzo.
Izakhiwo zokubopha: I-HPMC inomthelela omkhulu ekusebenzeni nasekubambeleleni kodaka. Ukunamathela okukhulu kubangela ukumelana okuphezulu kwe-shear futhi kudinga amandla amakhulu ngesikhathi sokwakha, okuholela ekunciphiseni kokusebenza. Mayelana nemikhiqizo ye-cellulose ether, i-HPMC ibonisa ukunamathela okumaphakathi.
Ukugeleza nokusebenza: I-HPMC inganciphisa ukungqubuzana phakathi kwezinhlayiya, ikwenze kube lula ukukusebenzisa. Lokhu kulawuleka okuthuthukisiwe kuqinisekisa inqubo yokwakha esebenza kahle kakhudlwana.
Ukumelana nokuqhekeka: I-HPMC yenza i-matrix eguquguqukayo ngaphakathi kodaka, inciphisa izingcindezi zangaphakathi futhi inciphise ukwenzeka kokuqhekeka kokuncipha. Lokhu kwandisa ukuqina okuphelele kodaka, okuqinisekisa imiphumela ehlala isikhathi eside.
Amandla Acindezelayo Nama-Flexural: I-HPMC inyusa amandla aguquguqukayo odaka ngokuqinisa i-matrix futhi ithuthukise ukuhlangana phakathi kwezinhlayiya. Lokhu kuzokwandisa ukumelana nezingcindezi zangaphandle futhi kuqinisekise ukuzinza kwesakhiwo.
Ukusebenza okushisayo: Ukwengezwa kwe-HPMC kungakhiqiza izinto ezilula futhi kunciphise isisindo. Lesi silinganiso esiphezulu se-void sisiza ngokufaka ukushisa okushisayo futhi singanciphisa ukuqhutshwa kukagesi kwento ngenkathi igcina ukushisa okungaguquki lapho ingaphansi kokushisa okufanayo. ubuningi. Ukumelana nokudlulisa ukushisa ngephaneli kuyahlukahluka ngenani le-HPMC elingeziwe, ngokufakwa okuphezulu kakhulu kwesengezo okuholela ekwenyukeni kokumelana nokushisa uma kuqhathaniswa nengxube yereferensi.
Umphumela wokungenisa umoya: Umphumela wokungenisa umoya we-HPMC ubhekisela eqinisweni lokuthi i-cellulose ether iqukethe amaqembu e-alkyl, anganciphisa amandla angaphezulu esixazululo esinamanzi, akhulise okuqukethwe komoya ekuhlakazweni, futhi athuthukise ukuqina kwefilimu yebhamuza kanye nokuqina kwamabhamuza amanzi ahlanzekile. Iphakeme futhi kunzima ukuyikhipha.
Izinga lokushisa lejeli: Izinga lokushisa lejeli le-HPMC libhekisela emazingeni okushisa lapho ama-molecule e-HPMC akha ijeli esixazululweni esinamanzi ngaphansi kokuhlushwa okuthile kanye nenani le-pH. Izinga lokushisa lejeli lingelinye lamapharamitha abalulekile ohlelo lwe-HPMC, oluthinta ukusebenza nomthelela we-HPMC emikhakheni ehlukahlukene yohlelo. Izinga lokushisa lejeli le-HPMC likhuphuka ngokunyuka kokugxila. Ukwanda kwesisindo samangqamuzana kanye nokuncipha kwezinga lokushintsha kuzophinde kubangele izinga lokushisa lejeli lenyuke.
I-HPMC inomthelela omkhulu ezimpahleni zodaka emazingeni okushisa ahlukene. Le mithelela ibandakanya ukugcinwa kwamanzi, ukusebenza kwebhondi, uketshezi, ukumelana nokuqhekeka, amandla acindezelayo, amandla okuguquguquka, ukusebenza okushisayo nokungena komoya. . Ngokulawula ngokunengqondo umthamo nezimo zokwakha ze-HPMC, ukusebenza kodaka kungathuthukiswa futhi ukusebenza kwayo nokuhlala isikhathi eside emazingeni okushisa ahlukene kungathuthukiswa.
