I-HPMC (HYDROXYPROPYL Methylcellulose)i-polymer esetshenziswa kakhulu ye-polymer esetshenziswa kabanzi emkhakheni wezikhangiso. Ibamba iqhaza elibalulekile ezicini eziningi zokunamathela.
1. Umsebenzi wokuqina we-ejenti
I-HPMC iyisikhulu esisebenzayo esingathuthukisa kakhulu ukubonwa nokuqina kwezikhangiso. Isakhiwo saso samangqamuzana sinamaketanga aqinile we-hydrophility nama-polysaccharide amaketanga, futhi angakha isisombululo se-colloidal esifanayo emanzini noma izixazululo ze-organic. Lesi sici singavimba ngempumelelo ukunamathela ekuziphatheni noma ekuxazululeni ngesikhathi sokugcina nokusebenzisa, ngaleyo ndlela kuqinisekiswe ukufana kokunamathela.
2. Ukusebenza okuthuthukile kokunamathela
I-HPMC inezindawo ezinhle kakhulu zokunamathela futhi ingathuthukisa kakhulu ukunamathela okunama-adhesive ku-substrate. Ngemuva kokuhlanganiswa ebusweni be-substrate, ama-molecule we-HPMC angangena emaphepheni amahle ngaphezulu ukuze athuthukise amandla abugqilayo futhi alungele izinto ezahlukahlukene ezinjengephepha, i-fiber, izinkuni nama-ceramics.
3. Izakhiwo ezenziwe ngefilimu
I-HPMCInezakhiwo ezinhle kakhulu ezakha amafilimu futhi zingenza ngokushesha i-Uniform nefilimu eqhubekayo ngemuva kokuhlanganisa. Le filimu inobunzima obuhle nokuqina futhi inganikeza ungqimba olwengeziwe lokuvikelwa kokunamathela, ukuthuthukisa ukuqina nokungangeni manzi kwesibopho. Ngaphezu kwalokho, le filimu inciphisa umthelela wezindawo zangaphandle, ezinjengomswakama noma izinguquko zokushisa, ekusebenzeni kokunamathelayo.
4. Ukugcinwa kwamanzi
I-HPMCInomthamo omuhle kakhulu wokugcina amanzi futhi ingakhiya umswakama ekunamathisweni ukuvikela ukulahleka kwamanzi ngokweqile. Lesi sici sibaluleke kakhulu ekunamatheleni okususelwa emanzini kanye nezinto zokwenziwa kokonamba, ezinganwebeka isikhathi sokuvula, senze lula ukwakhiwa, futhi sigweme ukomisa i-shrinkage noma ukonakala ekuwohlokeni kokusebenza kwamabhondi okubangelwa ukuhwamuka kwamanzi okubangelwa ngokushesha kwamanzi.
5. I-Standil Express
I-HPMC ingathuthukisa kakhulu ukuqina kohlelo lokunamathela, vimba ukulungiswa noma okuhlanganisiwe kwezinhlayiya eziqinile, futhi kugcinwe ukufana komkhiqizo. Amaqembu asebenzayo eqoqweni lawo le-molecular angasebenza futhi ngokuxhumana nezinye izakhi ukwenza ngcono ukuqina nokusebenza kwefomula.
6. Ubungane bezemvelo
I-HPMC ingumkhiqizo otholwe ukuguqulwa kwamakhemikhali we-cellulose yemvelo. Akulona ubuthi, okungenangozi futhi kungathandeki. Ukusetshenziswa kwayo ezinamatheliso kuhambisana nezidingo zanamuhla zokuvikelwa kwemvelo futhi kunezinzuzo ezibalulekile ikakhulukazi ekwakhiweni, ezindlini zokupakisha nezidla.
7. Lungisa i-Rheelogy
Izakhiwo ezikhethekile zembongo ze-HPMC ngesixazululo (ezinjenge-Shear Thwerning) zinika amandla anamathela ukuze abe nezindawo ezinhle zokwakha ngesikhathi. I-viscosity yayo inciphisa ngaphansi kwezimo eziphakeme kakhulu, okwenza kube lula ukupenda, fafaza noma i-scrupe, ngenkathi ukubonakala kwayo kutholakele ngaphansi kwezimo eziphansi ze-shear, kuqinisekiswe ukunamathela okuhle kwezinto eziphansi.
Izindawo zohlelo lokusebenza
Njengengxenye ebalulekile yezikhangiso, i-HPMC isetshenziswa kabanzi kule mikhakha elandelayo:
Imboni Yokwakha: njenge-tile anamathela, i-putty powder, udaka owomile oluhlanganisiwe, olusetshenziselwa ukuthuthukisa ukusebenza kokwakha namandla ebopha.
Ukunamathelisa ngokhuni: Thuthukisa umphumela wokubopha phakathi kwezinkuni nokuvimbela ukuqhekeka.
Ukuphanga nokuphrinta: Kusetshenziselwa ukukhomba amaphepha ukuthuthukisa bushelelezi kanye nokunamathelisa.
Indwangu nesikhumba: Isetshenziselwa ukucubungula kwe-fiber kanye nesibopho sesikhumba.
I-HPMCIdlala izindima eziningi ezinamatheyisi njengokuqina, ukugcinwa kwamanzi, ukuqina, ukuthuthukiswa kokuqhamuka kanye nokwakheka kwefilimu. Iphinde ibe nezinzuzo zokuvikelwa kwemvelo kanye ne-Rhelogy eguqukayo. Lezi zakhiwo zikwenza kube yingxenye ebaluleke kakhulu futhi ebaluleke kakhulu ekunikezelweni okunamathela, ukuhlinzeka ngokusekelwa okubalulekile kokwenza ngcono ukusebenza komkhiqizo nokuhlangana nezidingo ezahlukahlukene.
