Ngaphambi kokukhiqiza inhlanganisela engancibiliki, kuyadingeka ukuthi ufunde ngokucophelela imibhalo yenqubo yokukhiqiza kanye nezidingo kanye nezinyathelo zokuphepha zesilinganiso se-adhesive engena-solvent, izinga lokushisa lokusetshenziswa, umswakama, izimo zokuphulukisa, nemingcele yenqubo.Ngaphambi kokukhiqiza, kuyadingeka ukuqinisekisa ukuthi imikhiqizo yokunamathisela esetshenzisiwe ayinakho okungavamile.Uma kutholakala noma yiziphi izenzakalo ezingavamile ezithinta i-viscosity, kufanele zimiswe ngokushesha futhi zixhunywe nabasebenzi bezobuchwepheshe benkampani.Ngaphambi kokusebenzisa umshini we-laminating we-solvent-free, kuyadingeka ukushisa kuqala uhlelo lokuxuba, uhlelo lwe-gluing, kanye nesistimu ye-laminating kusengaphambili.Ngaphambi kokukhiqizwa kwe-solvent-free composite, kuyadingeka ukuqinisekisa ukuthi ingaphezulu lama-roller enjoloba, ama-roller aqinile, nokunye.izingxenye zemishini emshinini oyinhlanganisela ongena-solvent zihlanzekile.
Ngaphambi kokuqala, kuyadingeka ukuthi uqinisekise futhi ukuthi ikhwalithi yomkhiqizo oyinhlanganisela iyahlangabezana yini nezidingo zokukhiqiza okuyinhlanganisela.Ukushuba kwesimo sefilimu ngokujwayelekile kufanele kube kukhulu kunama-dynes angama-40, futhi ukungezwani okungaphezulu kwamafilimu e-BOPA nawe-PET kufanele kube kukhulu kunama-dynes angama-50.Ngaphambi kokukhiqizwa ngobuningi, ukwethembeka kwefilimu kufanele kuhlolwe ngokuhlolwa ukuze kugwenywe izingozi.Hlola noma yikuphi ukuwohloka noma okungavamile kokunamathelayo.Uma kukhona okungahambi kahle kutholakala, lahla ingcina bese uhlanza umshini wokuhlanganisa.Ngemva kokuqinisekisa ukuthi akukho okungavamile ku-adhesive, sebenzisa inkomishi elahlayo ukuze uhlole ukuthi isilinganiso somshini wokuxuba silungile.Ukukhiqiza kungaqhubeka kuphela ngemva kokuthi ukuchezuka kungaphakathi kuka-1%.
Phakathi nenqubo yokukhiqiza, kuyadingeka ukuqinisekisa ikhwalithi yomkhiqizo.Ngemuva kokuhlanganiswa okujwayelekile kwe-100-150m, umshini kufanele umiswe ukuze kuqinisekiswe ukuthi ukubukeka okuyinhlanganisela, inani lokumboza, ukungezwani, njll. komkhiqizo kuyahlangabezana yini nezidingo.Phakathi nenqubo yokukhiqiza, yonke imingcele yenqubo, okuhlanganisa izinga lokushisa lemvelo, umswakama, i-substrate eyinhlanganisela, nemingcele yenqubo yemishini, kufanele irekhodwe ukuze kube lula ukulandelwa nokuhlonza izinkinga zekhwalithi.
Imingcele yezobuchwepheshe efana nokusetshenziswa nendawo yokugcina izinto enamathelayo, izinga lokushisa lokusetshenziswa, isikhathi sokusebenza, kanye nesilinganiso se-adhesive engancibilikiyo kufanele ibhekisele kumanuwali obuchwepheshe bomkhiqizo.Umswakama endaweni yokusebenzela kufanele ulawulwe phakathi kuka-40% -70%.Uma umswakama ungu-≥ 70%, xhumana nezisebenzi zenkampani yezobuchwepheshe futhi wandise ngokufanelekile ingxenye ye-isocyanate (ingxenye ye-KangDa New Material A), futhi ukuqinisekise ngokuhlolwa kwezinga elincane ngaphambi kokusetshenziswa okusemthethweni kweqoqo.Uma umswakamo wemvelo ungu-≤ 30%, xhumana nezisebenzi zenkampani yezobuchwepheshe futhi wandise ngokufanelekile ingxenye ye-hydroxyl (ingxenye engu-B), futhi uqinisekise ngokuhlola ngaphambi kokusetshenziswa kweqoqo.Umkhiqizo kufanele uphathwe ngokucophelela ngesikhathi sokuthuthwa nokulayisha nokuthulula, ukugwema ukuthinta, ukungqubuzana, nokucindezela okukhulu, nokuvimbela ukuchayeka komoya kanye nelanga.Kufanele igcinwe endaweni epholile, engenamoya, nezimo ezomile, futhi igcinwe ivaliwe isikhathi esiyizinyanga eziyisi-6.Ngemuva kokuthi umsebenzi oyinhlanganisela usuqediwe, izinga lokushisa lokuphulukisa liyi-35 ° C-50 ° C, futhi isikhathi sokuphulukisa silungiswa ngokuvumelana nezingxenye ezihlukene eziyinhlanganisela.Umswakama wokwelapha ngokuvamile ulawulwa phakathi kuka-40% -70%.
