I-lamination engenaso isinyibilikisi isivuthiwe emakethe, ikakhulukazi ngenxa yemizamo yamabhizinisi okupakisha kanye nabaphakeli bezinto zokwakha, ikakhulukazi ubuchwepheshe be-lamination ye-aluminium emsulwa yokuguqula izinto buthandwa kakhulu, futhi buthathe isinyathelo esikhulu ngaphansi kwezimo zemvelo zokufaka esikhundleni se-lamination yendabuko eyisisekelo sesinyibilikisi kanye nokukhiqizwa kwe-lamination ekhishwe ngaphandle. Amabhizinisi okupakisha abhekene nezinkinga ezahlukahlukene zekhwalithi ngenxa yezimo ezahlukene zemikhiqizo emishinini, ekusebenzeni, ezintweni zokusetshenziswa, ubuchwepheshe bekhwalithi kanye nokusetshenziswa. Leli phepha lizokhuluma ngenkinga ekhona, okungukuthi, ikhono lesikhwama sokuvula kanye nokushelela kwaso.
Isibonelo, ifilimu ye-polyethylene enwetshiwe enezingqimba ezintathu evamile yakhiwe ngengqimba ye-corona, ungqimba olusebenzayo oluphakathi kanye nongqimba lwesivalo sokushisa oluphansi. Ngokuvamile, izithasiselo zokuvula nezibushelelezi zengezwa kungqimba lokuvala olushisayo. Isithasiselo esibushelelezi sidluliselwa phakathi kwezingqimba ezintathu, kanti isithasiselo sokuvula asidluliswa.
Njengento yokuvala okushisa, izithasiselo zokuvula nezibushelelezi ziyadingeka lapho kukhiqizwa izinhlanganisela zokupakisha eziguquguqukayo. Zihlukile kakhulu, kodwa abakhiqizi abaningi bokupakisha abaqondi kahle ukuthi ziyafana.
Isithako esivamile sokuvula yi-silicon dioxide etholakala kwezentengiselwano, okuyisithako esingaphili esingakhulisa ukumelana kwefilimu ekuqineni. Abanye abathengi bahlala bethola ukuthi izendlalelo ezimbili zesikhwama zibonakala zifiphele phakathi kwazo, njengezingilazi ezimbili ezihambisanayo. Uzoqaphela ukuthi kubushelelezi ukuyivula nokusula, okuvame ukuntuleka kwezithako zokuvula. Ngisho nabanye abenzi bamafilimu abayisebenzisi.
Isithako esibushelelezi esijwayelekile yi-Erucic acid amide, okuyimpuphu emhlophe evame ukunamathela ku-roller ye-lamination kanye ne-guide roller enqubweni ye-solvent-base laminating. Uma kungezwa i-ejenti ebushelelezi ngokweqile ngesikhathi senqubo ye-lamination engena-solvent, eminye izohlakazeka ibe ungqimba lwe-corona njengoba izinga lokushisa lokwelapha likhuphuka, okuholela ekwehleni kwamandla okuxebuka. Ifilimu yokuqala ye-lamination ecacile ye-PE ehlutshiwe ngomhlophe, ingasulwa ngezicubu. Kukhona indlela yokuhlaziya nokuhlola ukuthi amandla okuxebuka ancishisiwe athintwa yini yizithako ezibushelelezi ngokweqile, ukubeka ifilimu ye-laminate enamandla aphansi kuhhavini ku-80℃ imizuzu emihlanu, bese kuhlolwa amandla. Uma ikhula kakhulu, empeleni kuphethwa ngokuthi ukwehla kwamandla okuxebuka kungenxa ye-ejenti ebushelelezi kakhulu.
Uma kuqhathaniswa nokubuyiselwa emuva kwe-solvent-base lamination, indlela ye-solvent-free lamination ilula kakhulu ukufeza ukudluliselwa kanye nokuhlakazeka kwesithasiselo. Indlela evamile yokwahlulela i-solvent free laminating rewind ukuhlola ukuthi zincane futhi zicocekile ngokwanele ukuvumela ukugeleza okungcono kwesibili okubushelelezi kwezinti ezingenasosososo. Uma i-roller yefilimu ifanelana nokucindezela okuphezulu, isithasiselo esishelelayo cishe sizothuthela kungqimba olune-laminated, noma ngisho nakwengqimba yokuphrinta. Ngakho-ke, sihlala sididekile ngale nkinga. Esingakwenza ukunciphisa izinga lokushisa lokupholisa, ukwehlisa isisindo sokumboza, ukukhulula ifilimu, kanye nokwengeza izithasiselo ezibushelelezi kaninginingi. Kodwa ngaphandle kokulawula okuhle kwalokhu okungenhla, i-glue inzima ukuyiphulukisa futhi ibamba amanzi. Izithasiselo eziningi kakhulu ngeke zithinte kuphela amandla okuxebuka kwesikhwama sepulasitiki, kodwa futhi zithinte nokusebenza kwayo kokuvala okushisa.
I-KANDA NEW MATERIALS ikhiphe uchungechunge lwezinamathiselo zokuxazulula lezi zinkinga. I-WD8117A / B double component solvent-free adhesive iyisincomo esihle. Iqinisekiswe amakhasimende isikhathi eside.
| Isakhiwo | I-coefficient yokuqala yokungqubuzana | I-coefficient yokungqubuzana elaminethiwe |
| I-PET/PE30 | 0.1~0.15 | 0.12~0.16 |
I-WD8117A / B ingasetshenziswa ukuxazulula inkinga yamandla aphansi okuxebuka kanye nokusebenza kahle kokuvala ukushisa ngenxa yezithasiselo ezibushelelezi ngokweqile ebusweni ngaphandle kokufuna umenzi wefilimu wokuqala ukuthi azinciphise.
Ngaphezu kwalokho, i-WD8117A/B inezinye izakhiwo ezimbili:
1. Amandla okuxebuka e-OPP / AL / PE angaphezu kuka-3.5 N, asondele noma aphezulu kunalawo amanye ama-glue e-laminating asekelwe ku-solvent.
2. Ukupholisa okusheshayo. Ngaphansi kwezimo eziphakanyisiwe, ifilimu yokulamina inganciphisa isikhathi sokupholisa esingamahora angaba ngu-8, okuphakamisa kakhulu ukusebenza kahle kokukhiqiza.
Ngamafuphi, ukunqunywa kokugcina kwe-friction coefficient yefilimu ehlanganisiwe kufanele kusekelwe kuma-static friction coefficients phakathi kwefilimu nepuleti lensimbi. Imibono eyiphutha yokuthi kunzima ukuvula isikhwama ngoba azikho izithasiselo ezanele zokushelela kufanele iqashelwe futhi ilungiswe. Singafinyelela kuphela ukuzinza kanye nemikhiqizo yokupakisha eguquguqukayo ephezulu ngesifinyezo ngasinye kanye nokuvuselelwa.
