Njengomkhiqizi wefilimu wokupakisha ovumelana nezimo, singathanda ukwethula ulwazi oluthile lwephakheji.Namuhla ake sikhulume mayelana nesici sokwenza imfuneko yokubeka izinto obala kwefilimu elaminate.
Kunesidingo esiphezulu sokungafihli kwefilimu ye-laminated emikhiqizweni yephakheji.Kodwa kuukucubungula okuhlanganisiwe kwefilimu yepulasitiki,inesimo sokuthiilaminated kuyintoukungafihli okwanele.
Ngakho, yini ethinta obala of theifilimu laminated?
Ukukhetha okungalungile kwe-adhesive:
Uma i-adhesive ngokwayo inombala omnyama noma i-fluidity enganele, ukusebenza kahle kwezinga, futhi ayikwazi ukusabalala ngokugcwele ku-substrate eyinhlanganisela.Ukuphakama kokuqukethwe okuqinile kwe-adhesive eyinhloko, kungcono ukuguquguquka kwayo, okuzuzisa ukusabalalisa kufilimu.Sekukonke, ukunamathela okungama-75% kunokucaca okungcono kunokunamathela okungu-50%, futhi okunamathelayo okungu-50% kungcono kunokunamathela okungu-40% noma okungu-35%.Kumafilimu anezidingo eziphezulu zokubonisa obala, kunzima ukufeza izidingo usebenzisa izinhlanganisela zokunamathela ezingama-50% nezingu-40%.
Iyacubungula:
Okokuqalaly, ilokushisa lokushisaofumshini oyinhlanganisela uphezulu kakhulu,okuyintoyome ngokushesha kakhuluumphumela ku-solvent esheshayo namagagasi weindawo ewuketshezi.Iglue ngaphambi kwesikhathiihlangana kalulanalapho ukushisaamandla ahambeku-glueungqimba lwangaphakathi, i-solvent ngaphansiifilimungizoukufakwa kwegesi.Lolu hloboikhefu legesiubusoifilimu efana nemigodi yentaba-mlilo,futhiindilingaswendandathoigesi yeglueyenza iigluungqimba alubonisi ngale.
Okwesibili, uma i-roller yokucindezela noma i-scraperiphukile futhi ibangele umoyaingcindeziiphuzu, futhiokuyimbangela yeifilimu opaque.
Okwesithathu,Banguuthuli oluningi kakhulu emoyeni endaweni yokusebenza,Iuthuli emoyeni oshisayokukhonaamunce omisweinqubongemuva kweglue.Banamathele kuubuso be-glue layer nomaphakathi nendawoisisekelo ezimbiliedifilimu,lezi nazoimbangelaing iukungacaceli kahleifilimu laminated.
Isixazululo siwukuthiusebenzisa inombolo ephezulu yesihlungi endaweni yokomisa umoyaukuvimba ukumuncwa kothuli.
Ekugcineni, ongcolile wei-adhesive roller izokwenza i-i-laminatedifilimu ayikhanyi ngokwanele.Ngesikhathi esifanayo, iingcina enganele enamabhamuza amancanekuzophumelaphakathiumoyaamabalafuthiopaque.
Isixazululo siwukuthiQinisekainani legluekwanele futhiahlanganiswe ngokulinganayo.
Eminye imibuzo:
I-tizinga lokushisa lenhlanganisela eshisayogingqaayiyonaiphakeme kakhulu, engakwazi't ncibilikaingcina.Iizinga lokushisa elipholile le-roller liphezulu kakhulu futhiimbangelaukuhluleka ukupholisa ngokushesha.Zonke lezikuholela ekungafihli kahle kwefilimu.
Isixazululo:Tyena lokushisa isigubhu esishisayo ngeke kubengaphansi70 degrees.The hot melt ingxenye colloid iqala ukuncibilika lapho izinga lokushisa ifinyelela 65 degrees.Ngakho,obalanokuqina ifilimu laminated kukhonangcono.
Irola yokupholisa kufanele isebenzise amanzi okupholisa noma ukupholisa ukujikeleza kwamanzi abandayo.Tyena ngokusheshaof isivinini sokupholisa, ukucaca okungconosingathola.Futhi, kuyinzuzo ku-flatness kweukucubungula ifilimu laminated.
Ngethemba ukuthi lonke ulwazi lobuchwepheshe olungenhla luwusizo kuwe.
