IHydroxypropyl methylcellulose, evame ukubizwa ngokuthi i-HPMC, iyipolymer esetshenziswa kakhulu emkhakheni wokudla, imithi, ukwakhiwa, izimonyo, kanye nemikhiqizo yokunakekelwa komuntu siqu.Kuyi-ether ye-cellulose yemvelo eyakhiwe ukuguqulwa kwamakhemikhali e-cellulose, i-polymer yemvelo etholakala ezitshalweni.Inqubo yokuguqula ibandakanya ukwethulwa kwamaqembu e-hydroxypropyl kanye ne-methyl ku-molecule ye-cellulose, eshintsha izici zayo futhi iyenze ibe nezinto ezihlukahlukene kakhulu ukuze isetshenziswe kuhlelo olubanzi lwezinhlelo zokusebenza.
Kunezinhlobo ezimbalwa ze-HPMC ezitholakala emakethe, ngayinye inezindawo zayo ezihlukile eziyenza ifanelekele izinhlelo zokusebenza ezithile.Kulesi sihloko, sizoxoxa ngezinhlobo ezinkulu ze-HPMC, izici zabo kanye nezicelo.
1. I-HPMC E5
I-HPMC E5 iwuhlobo lwe-HPMC ene-viscosity ephansi futhi ibonakala ngokunamathela kwayo okuhle, ukugcinwa kwamanzi kanye nezakhiwo eziqina.Ivamise ukusetshenziswa embonini yezokwakha njengesengezo emikhiqizweni esekwe usimende ukuthuthukisa ukusebenza kwayo, ukugcinwa kwamanzi, namandla okubopha.Ibuye isetshenziselwe ukukhiqizwa kwamathayela e-ceramic, imikhiqizo ye-gypsum, kanye nenhlanganisela yokukhonkolo.Embonini yokudla, isetshenziswa njenge-ejenti yokuqina emikhiqizweni yobisi, amasoso, namasobho.
2. I-HPMC E15
I-HPMC E15 iwuhlobo lwe-HPMC ene-viscosity emaphakathi futhi ibonakala ngokugcina kwayo amanzi amaningi, ukujiya nokuhlakaza izakhiwo.Ivame ukusetshenziswa njenge-ejenti yokuqina kanye nokuqiniswa ekukhiqizweni kokudla, kanye nasembonini yezemithi njenge-excipient yokuthuthukisa i-viscosity kanye nokuvumelana kwezidakamizwa.Ibuye isetshenziswe ekukhiqizeni izimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu ukuthuthukisa ukuthungwa nokuzinza kwazo.
3. I-HPMC E50
I-HPMC E50 iwuhlobo lwe-HPMC ene-viscosity ephezulu futhi ibonakala ngokujiya kwayo okuhle kakhulu, ukugcinwa kwamanzi kanye nezakhiwo zefilimu.Isetshenziswa kakhulu ekukhiqizeni ama-coatings, amapende, nama-adhesives njenge-thickener ne-binder.Ibuye isetshenziswe embonini yokudla ukuze kuthuthukiswe ukuthungwa nokuzinza kwemikhiqizo efana nezimpahla ezibhakiwe, ushizi, nenyama egayiwe.
4. I-HPMC K4M
I-HPMC K4M iwuhlobo lwe-HPMC ene-viscosity ephezulu futhi ibonakala ngokujiya kwayo okuhle kakhulu nokunamathelayo.Ivamise ukusetshenziswa embonini yezemithi njengento esizayo ukuze kuthuthukiswe izinga lokuqedwa kanye ne-bioavailability yezidakamizwa, kanye nokulungisa iphrofayili yokukhishwa kwezidakamizwa.Iphinde isetshenziswe embonini yokudla ukuthuthukisa ukuthungwa nokuzinza kwemikhiqizo efana neziphuzo, ukudla okulula, nama-dessert afriziwe.
5. I-HPMC K100M
I-HPMC K100M iwuhlobo lwe-HPMC ene-viscosity ephezulu kakhulu futhi ibonakala ngokujiya kwayo okuhle kakhulu, ukwakheka kwefilimu kanye nezakhiwo ezikhishwa ngokuqhubekayo.Ivamise ukusetshenziswa embonini yezemithi njengesisetshenziswa sokuthuthukisa i-bioavailability nokukhululwa okulawulwayo kwezidakamizwa.Ibuye isetshenziswe ekukhiqizeni okunamathelayo, opende, nezinamatheliso ukuze kuthuthukiswe izakhiwo zabo zokujiya nokubopha.
Sengiphetha, i-HPMC iyi-polymer eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezahlukahlukene.Izinhlobo ezahlukene ze-HPMC ezitholakala emakethe zenza kube nokwenzeka ukukhetha efaneleka kakhulu kuhlelo lokusebenza oluthile ngokusekelwe ezimpahleni nezici zayo.Umthelela omuhle we-HPMC ezimbonini ezihlukahlukene ukwenze kwaba ukukhetha okudumile njengesengezo emikhiqizweni eminingi.
