IHydroxypropyl methylcellulose (HPMC) iwukuphuma okuvamile kwe-semi-synthetic cellulose esetshenziswa kabanzi kwezemithi, ukwakhiwa, ukudla nakweminye imikhakha.
(1) Izici eziyisisekelo ze-HPMC
I-HPMC iyimpushana emhlophe encibilika emanzini ukuze yakhe isixazululo se-viscous colloidal. Inokunamathela okuhle, ukuzinza nokuqina, futhi ingakha ifilimu esobala. Izakhiwo ze-HPMC zincike ezingeni le-methylation yayo ne-hydroxypropylation, ngakho-ke kukhona ukucaciswa nokusetshenziswa okuhlukile.
(2) Izindawo ezisetshenziswa kakhulu kanye nokusetshenziswa kwe-HPMC
1. Imboni yezemithi
a. Njengomuntu ophethe izidakamizwa kanye ne-ejenti ekhishwa isikhathi eside
I-HPMC ivamise ukusetshenziswa njenge-ejenti yokukhululwa okuqhubekayo emalungiselelweni ezidakamizwa. Kumaphilisi namaphilisi, i-HPMC ingenza ifilimu ezinzile futhi ilawule izinga lokukhululwa kwezidakamizwa. Uma isetshenziswa, i-HPMC ixutshwa nezithako zomuthi. Ngemuva kokufakwa kwethebhulethi noma ukugcwalisa i-capsule, i-HPMC ingakhulula kancane kancane umuthi epheshaneni lamathumbu.
b. Njengomuntu ohlanganisayo
Ekukhiqizweni kwethebhulethi, i-HPMC ivamise ukusetshenziswa njengesibophezelo. Uma ixubene nezinye izithako, ingathuthukisa amandla nokuzinza kwethebhulethi.
c. Njenge-ejenti emisiwe
Emithini ewuketshezi, i-HPMC ingavimbela ngempumelelo izithako zomuthi ukuthi zingahlali, ngaleyo ndlela igcine ukufana komuthi.
2. Imboni yezokwakha
a. Njenge-thickener yodaka lukasimende
Ekwakhiweni, i-HPMC isetshenziselwa ukuxuba usimende, isihlabathi nezinye izinto ukuze kuthuthukiswe ukunamathela nokusebenza kokwakhiwa kodaka. Kungathuthukisa ukugcinwa kwamanzi odaka futhi kuvimbele ukuthi ukoma ngokushesha, ngaleyo ndlela kwandise isikhathi sokusebenza sodaka.
b. Njengesengezo se-adhesive tile
I-HPMC ingasetshenziswa njengesengezo sokunamathisela ithayela ukuze kwandiswe ukunamathela nokusebenza kokwakhiwa kwe-adhesive futhi kuvinjwe izitini ukuthi zingawi.
3. Imboni yokudla
a. Njengesikhutha sokudla kanye nesiqinisi
I-HPMC ivamise ukusetshenziswa njengokujiya ekudleni, njengakumajamu, ojeli kanye neziphuzo. Ingakwazi ukwandisa i-viscosity yomkhiqizo futhi igcine ukuzinza komkhiqizo.
b. Njengefilimu yokudla yangaphambili
I-HPMC ingasetshenziswa ekwenzeni ifilimu yokupakisha ukudla ukuze yakhe ifilimu esobala ukuvikela ukudla.
4. Imboni yezimonyo
a. Njenge-thickener yezimonyo
I-HPMC ivamise ukusetshenziswa kuzimonyo, njengezihlanzi zobuso, okhilimu besikhumba, njll., njengendlela yokuqinisa ukwenza ngcono ukuthungwa nokuzinza komkhiqizo.
b. Njengomuntu owake wadlala ifilimu
I-HPMC ingakha ifilimu esobala futhi isetshenziswa njengefilimu yangaphambili emikhiqizweni yokunakekelwa kwesikhumba, njengamamaski obuso.
(3) Izinyathelo zokuqapha zokusetshenziswa kwe-HPMC
Ukuncibilika
Izinga lokuqedwa kwe-HPMC lithintwa izinga lokushisa nezimo ezinyakazayo. Qinisekisa ukuthi ingxube inyakaziswa ngokulinganayo ngesikhathi sokuncibilika ukugwema ukuhlangana.
Ukulawula ukugxila
Lungisa ukugcwala kwe-HPMC ngokwezidingo zohlelo lokusebenza. Emalungiselelweni emithi, ukugxila okuphezulu kakhulu kungase kuthinte izinga lokukhululwa komuthi; ezintweni zokwakha, ukugxila okuphansi kakhulu kungase kubangele ukusebenza okunganele kwempahla.
Izimo zokugcina
I-HPMC kufanele igcinwe endaweni eyomile, epholile, kugwenywe izinga lokushisa eliphezulu kanye nomswakama ukuze kugcinwe ukuzinza nokusebenza kwayo.
Ukuhambisana
Uma usebenzisa i-HPMC, ukuhambisana kwayo nezinye izithako kudinga ukucatshangelwa, ikakhulukazi uma isetshenziswa ezidakamizweni nasekudleni, ukuze kuqinisekiswe ukuthi akukho ukusabela okubi okwenzekayo.
I-HPMC iwukuphuma okuhlukahlukene kwe-cellulose okunezinhlobonhlobo zezinhlelo zokusebenza. Kusukela kwezemithi kuye kwezokwakha, ukudla kuye kwezimonyo, izakhiwo ezihlukile ze-HPMC ziyenza idlale indima ebalulekile emikhiqizweni eyahlukene. Lapho uyisebenzisa, kuyadingeka ukuthi ukhethe ukucaciswa okufanele kanye nokugxila ngokuya ngezidingo ezithile zohlelo lokusebenza, futhi unake ukunyibilika kwayo kanye nezimo zokugcinwa kwayo ukuze kuqinisekiswe ukusebenza kahle nokuzinza komkhiqizo.
