Izinamathiselo zamathayela zisetshenziswa kakhulu ukufaka amathayela ezindaweni ezahlukahlukene njengezindonga naphansi.Zibalulekile ukuze kuqinisekiswe isibopho esiqinile phakathi kwe-tile ne-substrate ukuze kugwenywe umonakalo ongase ube khona, nokuqinisekisa ukuthi ukufakwa kungakwazi ukumelana nezingcindezi ezihlukahlukene zemvelo ezifana nomswakama, izinguquko zokushisa nokuhlanza njalo.
Esinye sezithako ezivame ukusetshenziswa ekunamathiseleni amathayela i-hydroxypropylmethylcellulose (HPMC), i-polymer evame ukutholakala ku-cellulose.Iyaziwa ngekhono layo elihle kakhulu lokugcina amanzi, okwenza kube isithako esifanelekile ekwakhiweni kwe-adhesive adhesive.
Kunezinzuzo ezimbalwa zokusebenzisa i-HPMC ekwakhiweni kwe-adhesive tile.Lokhu kubandakanya;
1. Thuthukisa ukusebenza
I-HPMC isebenza njengesilungisi se-rheology ekwakhiweni kukasimende okufana nokunamatheliswa kwamathayela, okusho ukuthi ingathuthukisa kakhulu ukusebenza kwezinamathelisi zamathayili.Iphinde inciphise ukubukeka kwezigaxa namahlule, okuthuthukisa ukuhambisana kwengxube, okwenza kube lula ukuthi abafakeli basebenze nabo.
2. Ukugcinwa kwamanzi
Enye yezinzuzo ze-HPMC ku-adhesives yamathayela amandla ayo okugcina amanzi amahle kakhulu.Iqinisekisa ukuthi i-adhesive ihlala isetshenziswa isikhathi eside futhi isiza i-adhesive ye-tile ukuthi isethe.Lesi sici siphinde sinciphise ingozi yokuqhekeka kokuncipha, okuvame ukubangelwa ukulahlekelwa kwamanzi ngesikhathi sokusetha.
3. Ukwanda kwamandla
Enye inzuzo yokusebenzisa i-HPMC ku-adhesives yamathayili ukuthi isiza ukukhulisa amandla engxube.Ukwengezwa kwe-HPMC kusiza ukuzinzisa ingxube, kwengeze amandla futhi kuthuthukise ukuqina kukonke kokunamathela kwethayela.
4. Yonga isikhathi
Izinamathiselo zamathayela eziqukethe i-HPMC zidinga ukuxutshwa kwesifaki esincane nesikhathi sokufaka ngenxa ye-rheology ethuthukisiwe.Ngaphezu kwalokho, izikhathi ezinde zokusebenza ezinikezwa yi-HPMC zisho ukuthi izindawo ezinkulu zingakhava, okuholela ekufakweni kwamathayela ngokushesha.
5. Yehlisa umthelela kwezemvelo
I-HPMC ingumkhiqizo wemvelo futhi ongaboli.Ngakho-ke, ukusetshenziswa kwe-HPMC kuzinto zokunamathisela zamathayela kunganciphisa umthelela wemvelo we-adhesive futhi kuhlangabezane nesidingo esikhulayo sezinto zokwakha ezinobungani bemvelo.
Kafushane, i-HPMC iyingxenye ebalulekile ekukhiqizeni okunamathelayo kwethayela kwekhwalithi ephezulu.Amandla ayo okugcina amanzi nokuthuthukiswa kwe-rheological kunikeza izinzuzo ezihlanganisa ukucutshungulwa okuthuthukisiwe, amandla akhulayo, umthelela oncishisiwe wemvelo nokonga isikhathi.Ngakho-ke, abanye abakhiqizi bokunamathela kuthayela basebenzise ukusetshenziswa kwe-HPMC ukuze bathuthukise amandla ebhondi yethayela futhi bakhulise ukuqina kwezinamatheliso zabo.
