I-solvent-free lamination isikhulile emakethe, ikakhulukazi ngenxa yemizamo yamabhizinisi okupakisha nabaphakeli bezinto ezibonakalayo, ikakhulukazi ubuchwepheshe be-aluminium obucwenge be-aluminum bokubuyisela emuva sebuthandwa kakhulu, futhi ithathe isinyathelo esikhulu ngaphansi kwezimo zemvelo zokuthatha indawo ye-solvent yendabuko- i-base lamination kanye nokukhiqizwa kwe-lamination extruded.Amabhizinisi okupakisha akhungethwe izinkinga ezahlukahlukene zekhwalithi ngenxa yezimo ezihlukene zemikhiqizo emishinini, ukusebenza, izinto ezingavuthiwe, ubuchwepheshe bekhwalithi nokusetshenziswa.Leli phepha lizokhuluma ngenkinga ekhona, okungukuthi, ikhono lokuvula isikhwama kanye nokushelela kwayo.
Isibonelo, ifilimu ye-polyethylene evamile enezendlalelo ezintathu yenziwe nge-corona layer, ungqimba olusebenzayo oluphakathi nendawo kanye nongqimba olungaphansi lophawu olushisayo.Ngokujwayelekile, izithasiselo zokuvula nezibushelelezi zengezwa kungqimba olushisayo lokuvala uphawu.Isengezo esibushelelezi sidluliswa phakathi kwezendlalelo ezi-3, futhi okungeziwe okuvulayo akudluliselwa.
Njengempahla yokuvalwa okushisayo, izithasiselo zokuvula nezibushelelezi ziyadingeka lapho kukhiqizwa izinhlanganisela zokupakisha eziguquguqukayo.Ahluke kakhulu, kodwa iningi labakhiqizi bokupakisha abaqondi ukuthi ayafana.
Isengezo esivamile sokuvula i-silicon dioxide etholakalayo ukuze ihwebe, okuyizinto ezingaphili ezingakhuphula ukumelana kwefilimu ku-viscosity.Amanye amakhasimende ahlala ethola ukuthi izendlalelo ezimbili zesikhwama zibonakala zilufifi phakathi kwazo, njengezingilazi ezimbili ezidlulanayo.Uzoqaphela ukuthi kubushelelezi ukuvula nokusula, okuvamise ukushoda ekuvuleni izithasiselo.Futhi ngisho nabanye abenzi bamafilimu abayisebenzisi.
Isengezo esivamile esibushelelezi yi-Erucic acid amide, okuyimpushana emhlophe evame ukunamathela ku-lamination roller kanye ne-guide roller kunqubo ye-solvent-base laminating.Uma okweqile kwe-ejenti ebushelelezi yengezwa phakathi nenqubo yokucwenga i-solvent-free, enye izohlakazeka kungqimba lwe-corona njengoba izinga lokushisa lokwelapha likhuphuka, okuholela ekwehleni kwamandla okuxebuka.Ifilimu ye-PE ye-lamination yasekuqaleni ehlutshiwe ngomhlophe, ingasulwa ngezicubu.Kukhona indlela yokuhlaziya nokuhlola ukuthi amandla okuxebuka ancishisiwe athintwa ukweqisa kwezithasiselo ezibushelelezi, ukubeka ifilimu ye-laminate enamandla aphansi kuhhavini ongu-80℃imizuzu emihlanu, bese uhlola amandla.Uma ikhula kakhulu, empeleni kuphetha ngokuthi ukuncipha kwamandla okuxebuka kungenxa ye-ejenti ebushelelezi kakhulu.
Uma kuqhathaniswa ne-rewind ye-solvent-base lamination, indlela ye-solvent-free lamination ilula kakhulu ukufeza ukudluliswa okungeziwe nokuhlakazeka.Indlela evamile yokwahlulela i-solvent free laminating rewind ukuhlola ukuthi iminyene futhi icocekile ngokwanele ukuvumela ukugeleza okungcono kwesibili okubushelelezi kwezinamatheliso ezingenayo i-solvent.Ukucindezela okuphezulu kwe-roller yefilimu kufanelana, isithasiselo esishelela kakhulu kungenzeka sifudukele kungqimba olune-laminated, noma ngisho nosendlalelo sokuphrinta.Ngakho-ke, sisadidekile ngalolu daba.Esingakwenza ukunciphisa izinga lokushisa lokuphulukisa, ukwehlisa isisindo sokumboza, ukukhulula ifilimu, futhi sengeze izithasiselo ezibushelelezi ngokuphindaphindiwe.Kodwa ngaphandle kokulawula okuhle okungenhla, ingcina kunzima ukuyelapha futhi ibamba amanzi.Izithasiselo eziningi kakhulu ngeke zithinte kuphela amandla okuxebuka esikhwama sepulasitiki, kodwa futhi zithinte ukusebenza kwayo kokuvalwa okushisayo.
I-KANDA NEW MATERIALS ikhiphe uchungechunge lwezinto zokunamathisela ukuxazulula lezi zinkinga.I-WD8117A / B enamathelayo engancibiliki kabili iyisincomo esihle.Igunyazwe amaklayenti isikhathi eside.
| Isakhiwo | I-coefficient yoqobo yokungqubuzana | I-coefficient ene-laminated of friction |
| I-PET/PE30 | 0.1~0.15 | 0.12~0.16 |
I-WD8117A / B ingasetshenziselwa ukuxazulula inkinga yamandla angenamandla okuxebula nokusebenza kokuvala okushisayo ngenxa yezithasiselo ezibushelelezi ezingaphezulu ngaphandle kokudinga umenzi wefilimu wangempela ukuthi azinciphise.
Ukwengeza, i-WD8117A/B inezindawo ezimbili ezengeziwe:
1. Amandla okuxebuka e-OPP/AL/PE angaphezulu kuka-3.5 N, asondele noma angaphezulu kunawamanye ama-adhesive e-solvent-base laminating.
2. Ukwelapha ngokushesha.Ngaphansi kwezimo eziphakanyisiwe, ifilimu e-laminating ingafinyeza isikhathi sokuphulukisa cishe amahora angu-8, okukhuphula kakhulu ukusebenza kahle kokukhiqiza.
Ukufingqa, ukunqunywa kokugcina kwe-friction coefficient yefilimu eyinhlanganisela kufanele kusekelwe ku-static coefficients phakathi kwefilimu ne-steel plate.Imibono eyiphutha yokuthi kunzima ukuvula isikhwama ngoba azikho izithasiselo ezibushelelezi ezanele kufanele ibonwe futhi ilungiswe.Singazuza kuphela ukuzinza kanye nemikhiqizo yokupakisha eguquguqukayo ephakeme ngesifinyezo ngasinye kanye nokubuyekeza.
