IHydroxypropyl methylcellulose (HPMC) i-ether cellulose evamise ukusetshenziswa njengesengezo ezintweni ezisekelwe kusimende. Izakhiwo zayo eziguquguqukayo ziyenza ibe yigugu ezinhlobonhlobo zezicelo embonini yezokwakha. Ukusetshenziswa okuyinhloko kwe-HPMC kusimende kufaka:
1. Ukugcinwa kwamanzi:
Umsebenzi: I-HPMC isebenza njenge-ejenti egcina amanzi.
Okubalulekile: Kuvimbela ukuhwamuka okusheshayo kwamanzi engxubeni kasimende, kuqinisekiswe ukuthi amanzi anele ayatholakala ukuze kufakwe amanzi ezinhlayiyeni zikasimende. Lokhu kusiza ukuthuthukisa ukusebenza kahle futhi kuthuthukise ukhonkolo wokugcina oqinile nohlala isikhathi eside noma udaka.
2. Ukulawula ukujiya kanye ne-rheology:
Umsebenzi: I-HPMC isebenza njenge-thickener futhi isiza ekulawuleni i-rheology.
Okubalulekile: Ngokulawula i-viscosity yengxube kasimende, i-HPMC isiza ukuvimbela ukuhlukaniswa kanye nokuhlaliswa kwezinhlayiya eziqinile. Ithuthukisa ukusebenza kanye nezakhiwo zokusetshenziswa kwezinto ezisekelwe kusimende, okwenza kube lula ukuphatha.
3. Thuthukisa ukunamathela:
Umsebenzi: I-HPMC ithuthukisa ukunamathela.
Okubalulekile: Ukwengezwa kwe-HPMC kuthuthukisa ukunamathela phakathi kwezinto zikasimende nama-substrates ahlukahlukene. Lokhu kubaluleke kakhulu ekusetshenzisweni okufana nokunamathiswa kwamathayili, lapho ukunamathela okuqinile kubalulekile ekuphileni isikhathi eside nokusebenza kwendawo yethayili.
4. Setha ukulawula isikhathi:
Umsebenzi: I-HPMC isiza ukulawula isikhathi sokujiyisa.
Okubalulekile: Kubalulekile kumaphrojekthi wokwakha ukulungisa isikhathi sokusetha ukuze sihlangabezane nezidingo ezithile. I-HPMC ingakwazi ukulungisa kahle isikhathi sokusetha sezinto ezisekelwe kusimende, inikeze ukuguquguquka kwezinhlelo zokusebenza ezihlukahlukene.
5. Nweba amahora okuvula:
Umsebenzi: I-HPMC inweba amahora okuvula.
Okubalulekile: Isikhathi sokuvula isikhathi lapho izinto ezisekelwe kusimende zihlala zisebenza ngemva kokwakhiwa. I-HPMC yelule lesi sikhathi ukuze yenze ukusetshenziswa nokulungiswa kwezinto kube lula kakhulu.
6. Ukumelana nokuqhekeka:
Umsebenzi: I-HPMC ithuthukisa ukumelana nokuqhekeka.
Okubalulekile: Ngokwandisa ukuguquguquka nokunamathela kwe-matrix kasimende, i-HPMC isiza ukwehlisa amathuba okuqhekeka kwezinto ezilashiwe. Lokhu kunenzuzo ikakhulukazi ezindaweni lapho kushintsha khona izinga lokushisa noma ukunyakaza kwesakhiwo.
7. Yehlisa ukushwabana:
Ekwenzayo: I-HPMC isiza ekunciphiseni ukushwabana.
Okubalulekile: Ukuncipha kungabangela ukuqhekeka kwezinto ezisekelwe kusimende. I-HPMC isiza ukuzuza ivolumu ezinzile ngesikhathi sokwelashwa, inciphisa ubungozi bezinkinga ezihlobene nokuncipha.
8. Okunamathelayo kwethayela okusekelwe kusimende:
Umsebenzi: I-HPMC isetshenziswa kabanzi kuma-adhesive tile e-ceramic.
Kungani kubalulekile: Ekwakhekeni kwe-adhesive adhesive, i-HPMC inikeza ukunamathela okudingekile, ukusebenza kahle kanye nesikhathi esivulekile esidingekayo ukuze kufakwe kahle. Iqinisekisa isibopho esiqinile phakathi kwe-tile ne-substrate.
9.Ukufakwa ngaphansi kokuzilinganisa:
Umsebenzi: I-HPMC isetshenziselwa ukubeka ngaphansi kokuzilinganisa.
Kungani kubalulekile: Ekwakhekeni kokuzilinganisa, i-HPMC isiza ukufeza izici zokugeleza ezifiselekayo futhi ivimbele ukuhlukana nokuzinza. Isiza ukukhiqiza indawo ebushelelezi futhi elinganayo.
10. Udaka noPlaster:
Inhloso: I-HPMC ivamise ukungezwa odakeni nakuplasta.
Okubalulekile: I-HPMC ithuthukisa ukusebenza, ukunamathela kanye nokusebenza kukonke kodaka namapulastele ekupulasikeni nasekuqedeni izinhlelo zokusebenza.
Ukusetshenziswa kwe-hydroxypropyl methylcellulose ezintweni ezisekelwe kusimende kuningi. Ibhekana nezinselele ezihlukahlukene ezihlobene nokwakhiwa, ukusetshenziswa nokusebenza kwalezi zinto zokwakha, okuzenza zivumelane nezimo futhi zithembeke ezinhlobonhlobo zezicelo zokwakha.
