Ngokombono wezinto ezingavuthiwe nezinqubo, kunezizathu eziyisishiyagalombili zokungahlangani kahle kwamafilimu ayinhlanganisela: isilinganiso se-adhesive esingalungile, isitoreji sokunamathela esingafanele, i-diluent.iqukethe amanzi, insalela yotshwala, insalela yencibilikiyo, inani eliningi lokunamathela, isikhathi esinganele sokuphulukisa nezinga lokushisa, nezithasiselo.
1. Isilinganiso sokunamathela esingalungile
Isilinganiso sokunamatheliswa kukalwa ngokungalungile, okuholele ekwelapheni okunganele. Kulokhu, kuyadingeka ukukala zonke izinto zokwakha futhi urekhode inani ukuze lihlolwe kalula; Okwesibili, i-adhesive elungiselelwe kufanele ishukunyiswe ngokugcwele ngendlela efanele ukuze ugweme ukuxubana kwendawo engalingani.
2.Isitoreji esinamathelisi esingafanele
Ukugcinwa okungalungile kwe-adhesive kubangela ukuvalwa okungaphelele kwe-ejenti yokwelapha, okubangela ukuthi isabele ngomswakama emoyeni futhi idle enye ingxenye. Ngenxa yalokho, okuqukethwe okunganele kwe-ejenti yokwelapha kwenzeka ngesikhathi sokuxuba. Ngakho-ke, kuyadingeka ukuhlola isimo sokuvala i-adhesive ngaphambi kokusetshenziswa.
3.I-Diluent inamanzi
I-diluent ayihlanzekile ngokwanele futhi iqukethe amanzi amaningi, utshwala benza isilinganiso sokunamathelaukungalingani. Ukugcinwa kwe-diluent kufanele kuvalwe ngomswakama emoyeni ukuze ungangeni, futhi okuqukethwe kwamanzi e-diluent kufanele kuhlolwe njalo.
4. Izinsalela zotshwala
Ukusetshenziswa kwe-inki encibilikayo ngotshwala noma izingxenye zotshwala ezincibilikayo ziyinki azomiswa, izinsalela eziningi, ngakho-keukuthi ukusabela nge-ejenti yokwelapha, okuholela ekunamatheleni. Kufanele kusetshenziswe uyinki oncibilika otshwalenii-alcohol-soluble adhesive, i-solvent yokuphrinta ngangokunokwenzeka ukuze ungasebenzisi isilinganiso sotshwala.
5. Izinsalela ze-solvent
Kukhona i-solvent eyinsalela eningi kakhulu kufilimu ngesikhathi senqubo eyinhlanganisela, futhi i-solvent igoqwe nge-adhesive, evimbela ukuphulukiswa. Kuyadingeka ukuhlola njalo ukuthi i-inlet kanye ne-exhaust air yesistimu yokomisa ijwayelekile, futhi ulawule isivinini se-compound lapho amanzi e-gluing emakhulu.
6. Inani lokunamathela ngokweqile lokunamathela
I-adhesive iboshwe kakhulu, futhi ububanzi be-film roll bukhulu kakhulu, okuholela ekuhambeni kancaneukuqina kwangaphakathi kwe-adhesive. I-adhesive coating kufanele ifaneleke futhi ukuphulukiswa kufanele kube ngokwanele.
I-7.Isikhathi sokuphulukisa esinganele kanye nezinga lokushisa
Izinga lokushisa lokwelapha liphansi kakhulu, ukwelapha kuhamba kancane, futhi ukuxhumanisa akwanele. Izinga lokushisa elifanele lokuphulukisa kufanele likhethwe, isikhathi sokuphulukisa kufanele sanele, futhi okunamathelisa okwelapha ngokushesha kufanele kukhethwe uma kunesidingo. Isikhathi sokuphulukisa esinganele, izinga lokushisa alikwazi ukufinyelela, ikakhulukazi ekushiseni okuphezulubuyisela izikhwama, izobangela ukuhlukaniswa kombala wokuphrinta noma ukudluliswa kombala ngesikhathi sokushisa okuphezulu.
8. Izithasiselo
Ithonya lezithasiselo ku-substrate yefilimu eyinhlanganisela, njengesengezo ku-PVDC singabambezelekafuthi kuvimbele ukuphulukiswa okuxhumanisa okunamathelayo, isithambile ku-PVC sisabela nge-NCOiqembu le-ejenti yokwelapha, kanye ne-plasticizer ye-PVC ethambile ingangena ku-adhesive, ezokwenzaukunciphisa amandla okubopha kanye nokuzinza okushisayo, ngakho-ke ukusetshenziswa kwe-ejenti yokwelapha kufanele kubeanda ngokufanele.
