Izizathu kunye nezisombululo ezichaphazela ukucaca kweteyiphu yokukhusela kwi-aluminium

Ukukhetha okungafanelekanga kwe-adhesive

Ukuba i-adhesive imnyama ngombala okanye ayinamanzi ngokwaneleyo, ukusebenza komgangatho kunokuba ngcono kwaye kusasazwe ngokupheleleyo kwi-tape yokukhusela e-laminated ye-aluminium. Ngokubanzi, okukhona uphezulu isiqulatho esiqinileyo sokuncamathelisa okukhokelayo, kokukhona i-fluidity ilungele ukusasazeka kwifilimu. I-75% yeglue ingcono kune-50% yesiphumo esicacileyo, kwaye i-50% ingcono kune-40% okanye i-35% yeglue. I-Laminating kunye ne-50% kunye ne-40% yokunamathela ingumceli mngeni kwi-tape yokukhusela ye-aluminium kunye neemfuno eziphezulu zokucaca.

Iingxaki kwinkqubo

Okokuqala, iqondo lokushisa lomjelo wokubhaka we-laminator liphezulu kakhulu; ukomisa kukhawuleza kakhulu, i-solvent yomgangatho weglue iyaguquguquka (i-evaporation), i-glue surface crusts ngokukhawuleza, emva koko xa ubushushu bungena ngaphakathi kwendawo yeglue, i-solvent engaphantsi kwefilimu yeglue iya kuba ngumphunga, xa irhasi igxalathelana kumphezulu wefilimu yeglu ukuze yenze intaba-mlilo efana ne-crater, isangqa semisesane, esenza ukuba umaleko weglue ungafihli ngokwaneleyo. Okwesibini, ukuba i-roller yoxinzelelo oluthobelayo okanye i-scraper ineziphene, indawo ethile yoxinzelelo ayiqini, kwaye ukubunjwa kwendawo kuya kubangela ukuba ifilimu emva kokuba ukuthotyelwa kungabonakali.

Apha ukujoyina indawo yokusebenza yomoya eluthulini kakhulu; emva kokuncamathelisa umoya oshushu wafunxa kumjelo wokomisa, kukho nothuli oluncamathelayo kumphezulu womaleko wokuncamathelisa okanye odibeneyo xa udityaniswe phakathi kwemigangatho emibini yefilimu esisiseko, uthuli oluninzi olubangelwa kukungafihli okanye ukungafihli kakuhle.

Isisombululo ngumatshini we-laminating ovaliweyo kwicala leglue, ukomisa i-air channel ye-channel kunye nenani eliphezulu le-mesh yezihlungi, ukuthintela uthuli olufakwe kuyo (oko kukuthi, ukucacisa umjelo wokomisa umoya oshushu eluthulini).

Ukongezelela, akukho roller yokusabalalisa, okanye i-roller yokusabalalisa ayihlambulukanga; iya kwenza ifilimu emva kokuba i-composite ayiguquki ngokwaneleyo, okanye i-composite kwisixa seglue ayanelanga, izikhala zeglue ezingalinganiyo, ifolda enamaqamza amancinci, okubangela amabala okanye i-opaque.

Isisombululo kukukhangela kunye nokulungelelanisa inani leglue ukwenzela ukuba yanele kwaye ifakwe ngokulinganayo, okubangelwa yinto eyaziwa ngokuba yi "hemp face film."

Ezinye Iingxaki

Kufuneka kuqatshelwe ukuba ubushushu bombhobho otshisayo we-laminating awuphezulu ngokwaneleyo, inxalenye eshushu ye-adhesive ayinyibiliki, iqondo lokushisa le-roller yokupholisa liphezulu kakhulu, kwaye akunakwenzeka ukuyipholisa ngokukhawuleza, yonke into. nto leyo enokukhokelela ekubeni ifilimu ingafihli kakuhle.

Isisombululo: ubushushu bombhobho oshushu akufanele bube ngaphantsi kwama-70 degrees; inxalenye eshushu encibilikayo yegel iya kuqala ukunyibilika kuphela xa izinga lokushisa lifikelela kuma-65 degrees; emva kokunyibilika, kungekuphela nje ukucaca kuya kuphuculwa, kodwa kunye nokuqina okudibeneyo kuya kwandiswa. Iirola zokupholisa kufuneka zipholiswe ngamanzi apholileyo okanye ukujikeleza kwamanzi abandayo; Isantya esikhawulezayo sokupholisa, ngcono ukubonakala, ngcono ukuthambeka kwefilimu edibeneyo, kwaye kungcono ukuqina.
