I-HPMC (Hydroxypropyl Methylcellulose)iwukuphuma kwe-cellulose encibilikisiwe emanzini esetshenziswa kabanzi embonini yezokwakha, ikakhulukazi odakeni, ezimbotsheni nasezintweni zokunamathisela. Iqhaza layo ekufutheni ngodaka oluyimishini ibaluleke kakhulu, njengoba ingathuthukisa ukusebenza kodaka, ithuthukise ukunamathela, ithuthukise uketshezi futhi yandise isikhathi sokuvula.
1. Thuthukisa ukuguquguquka nokusebenza kokwakhiwa kodaka
Omunye wemisebenzi ebaluleke kakhulu ye-HPMC ukwenza ngcono kakhulu uketshezi lodaka. Njengoba i-HPMC ine-solubility enhle yamanzi, ingakha isixazululo se-colloidal odakeni, ikhulise ukuhambisana kodaka, futhi iyenze ibe yinto efanayo futhi ibushelelezi ngesikhathi sokwakhiwa. Lokhu kubalulekile enqubweni yokufafaza ngomshini, okudinga uketshezi oluthile lodaka ukuze lufuthwe odongeni ngokucindezela okukhulu emishinini yokufafaza. Uma i-fluidity ye-mortar inganele, izodala ubunzima ekufutheni, ukumbozwa kwesifutho okungalingani, ngisho nokuvala umlomo wombhobho, ngaleyo ndlela kuthinte ukusebenza kahle kwesakhiwo kanye nekhwalithi.
2. Thuthukisa ukunamathela kodaka
I-HPMC inezici ezinhle zokubopha futhi ingathuthukisa ukunamathela phakathi kodaka kanye nesendlalelo sesisekelo. Ngodaka lwe-spray lwemishini, ukunamathela okuhle kubaluleke kakhulu, ikakhulukazi uma ukugqoka kusetshenziselwa ama-facade noma ezinye izinhlobo zama-substrates.I-AnxinCel®HPMCingathuthukisa ngempumelelo ukunamathela kodaka endaweni eyisisekelo futhi inciphise izinkinga zokuchitha ezibangelwa izici zemvelo (njengokushintsha kwezinga lokushisa nomswakama). Ngesikhathi esifanayo, i-HPMC ingaphinda ithuthukise ukuhambisana phakathi kodaka nezinye izinto ukuze kugwenywe ukuxebuka kwe-interlayer okubangelwa ukungafani kokuhambisana.
3. Nweba amahora okuvula futhi ugcine ukusebenza komsebenzi wokwakha
Ekwakheni isifutho ngomshini, ukwelula isikhathi sokuvula udaka kubalulekile kwikhwalithi yokwakha. Isikhathi sokuvula sibhekisela enkathini yesikhathi kusukela lapho udaka lufakwa phezulu kuze kube yilapho loma, futhi ngokuvamile ludinga ukuthi isisebenzi sokwakha sikwazi ukwenza izinguquko, ukusikeka kanye nokulungisa phakathi nalesi sikhathi ngaphandle kokuphazamisa ukusebenza kodaka. I-HPMC inganweba kakhulu isikhathi sokuvula ngokwandisa i-viscosity yodaka kanye nokunciphisa izinga lokuhwamuka kwamanzi. Lokhu kuvumela isifutho ukuthi sisebenze isikhathi eside futhi sigwema ukuqhekeka kwendawo noma ukufafaza okungalingani okubangelwa ukomiswa ngokushesha okukhulu.
4. Vimbela i-delamination kanye nemvula
Odakeni lokufafaza oluyimishini, ngenxa yokuhamba isikhathi eside nokugcinwa, ukuna kwezinhlayiyana kungase kwenzeke odakeni, kubangele ukubola kodaka. I-HPMC inezinto eziqinile zokumisa, ezingavimbela ngempumelelo izinhlayiya ezinhle noma ezinye izingxenye ezisesimendeni ukuthi zingahlali futhi zigcine ukufana kodaka. Lesi sici sibaluleke kakhulu ukuze kuqinisekiswe umphumela wokufafaza kanye nekhwalithi yodaka. Ikakhulukazi ekwakhiweni kwezinga elikhulu, ukugcina ukuhambisana nokuzinza kodaka kuyisihluthulelo sokuqinisekisa ikhwalithi yokwakha.
5. Thuthukisa ukugcinwa kwamanzi odaka
Njengenhlanganisela ye-polymer encibilika emanzini, i-HPMC inokugcinwa kwamanzi okuqinile. Yakha ifilimu elincanyana odakeni, ngaleyo ndlela inciphise ukuhwamuka komswakama. Lesi sakhiwo sibaluleke kakhulu ukugcina udaka lunomswakama futhi kuncishiswe ukwenzeka kwemifantu. Ikakhulukazi ezindaweni ezishisa kakhulu, ezinomswakama omncane, udaka luvame ukomiswa ngokushesha futhi luqhekeke. I-HPMC inganciphisa ngempumelelo ukwenzeka kwalesi simo ngokuthuthukisa ukugcinwa kwamanzi odaka kanye nokuqinisekisa ukuthi udaka lwelapheke ngokugcwele futhi lwelapheka ngesikhathi esifanele.
6. Thuthukisa ukumelana nokuqhekeka kanye nokuqina kodaka
Njengoba i-HPMC ingathuthukisa ukugcinwa kwamanzi kanye nezakhiwo zokubopha zodaka, ingaphinda ithuthukise ukumelana nokuqhekeka nokuqina kodaka. Phakathi nenqubo yokufafaza ngomshini, ukufana nokuzinza kongqimba lukadaka kubalulekile ekumelaneni nokuqhekeka isikhathi eside. Ngokuthuthukisa ukubumbana nokunamathela kobuso bodaka, i-AnxinCel®HPMC inciphisa ngempumelelo ingozi yokuqhekeka okubangelwa ukushintsha kwezinga lokushisa, ukuhlaliswa kwesakhiwo noma ezinye izici zangaphandle, futhi inweba impilo yesevisi yodaka.
7. Ukuthuthukisa ukunethezeka nokuzinza kwemisebenzi yokufafaza
Lapho kusetshenziswa imishini yokufutha eyimishini yokwakha, uketshezi, i-viscosity kanye nokuzinza kodaka kubalulekile ekusebenzeni okujwayelekile kwemishini. I-HPMC yehlisa ukuwohloka kwemishini yokufutha kanye nezidingo zokunakekelwa ngokuthuthukisa uketshezi kanye nokuzinza kodaka. Kungase futhi kunciphise inkinga yokufaka udaka noma ukuvala imishini, iqinisekise ukuthi okokusebenza kugcina ukusebenza okuzinzile phakathi nezinqubo zokwakha zesikhathi eside.
8. Ukuthuthukisa ukumelana nokungcola kodaka
I-HPMCinezindawo eziqinile zokulwa nokunukubezeka. Ingavimbela ukunamathela kwezinto eziyingozi noma ukungcola odakeni futhi igcine ukuhlanzeka kodaka. Ikakhulukazi kwezinye izindawo ezikhethekile, udaka luthinteka kalula ukungcola kwangaphandle. Ukwengezwa kwe-HPMC kungavimbela ngempumelelo ukunamathela kwalokhu kungcola, ngaleyo ndlela kuqinisekise izinga lokwakha nokubukeka.
Iqhaza le-HPMC odakeni lwe-spray oluyimishini linezici eziningi. Akukwazi nje ukuthuthukisa uketshezi kanye nokusebenza kokwakhiwa kodaka, kodwa futhi kuthuthukise ukunamathela, ukwelula isikhathi sokuvula, ukuthuthukisa ukugcinwa kwamanzi, ukuthuthukisa ukumelana nokuqhekeka kanye nokuthuthukisa ikhono lokulwa nokungcola, njll. Ngokungeza ngokunengqondo i-HPMC, ukusebenza okuphelele kodaka kungakwazi kube ngcono kakhulu, kuqinisekiswe ukuzinza kanye nomthelela wokusetshenziswa kwesikhathi eside kodaka ngesikhathi senqubo yokwakha. Ngakho-ke, i-HPMC isetshenziswa kabanzi ekwakhiweni kwesakhiwo sesimanje, ikakhulukazi osikeni lwemishini yokufutha, lapho idlala indima engenakuthathelwa indawo futhi ebalulekile.
