I-lamination engenazinyibilikisi ikhulile kwimarike, ikakhulu ngenxa yemizamo yamashishini okupakisha kunye nababoneleli bezinto, ingakumbi iteknoloji ye-lamination ye-aluminium ecocekileyo yokuguqula izinto ithandwa kakhulu, kwaye ithathe inyathelo elikhulu phantsi kweemeko zendalo zokutshintsha i-lamination yendabuko esisiseko se-solvent kunye nemveliso ye-lamination ekhutshiweyo. Amashishini okupakisha ajongene neengxaki ezahlukeneyo zomgangatho ngenxa yeemeko ezahlukeneyo zeemveliso kwizixhobo, ukusebenza, izinto eziluhlaza, iteknoloji yomgangatho kunye nokusetyenziswa. Eli phepha liza kuthetha ngengxaki ekhoyo, oko kukuthi, amandla okuvula kwesingxobo kunye nokuguda kwayo.
Umzekelo, ifilimu ye-polyethylene eqhelekileyo enamaleko amathathu yenziwe ngomaleko we-corona, umaleko osebenzayo ophakathi kunye nomaleko wesitywino sobushushu obuphantsi. Ngokwesiqhelo, izongezo zokuvula nezigudileyo zongezwa kumaleko wesitywino oshushu. Izongezo ezigudileyo zidluliselwa phakathi kwamaleko ama-3, kwaye izongezo zokuvula azidluliswa.
Njengento yokuvala ngobushushu, ukuvulwa kunye nezongezo ezigudileyo ziyimfuneko xa kusenziwa izinto zokupakisha eziguquguqukayo. Zahlukile kakhulu, kodwa uninzi lwabavelisi bokupakisha abaqondi ukuba ziyafana.
Isithako esiqhelekileyo sokuvula yi-silicon dioxide ethengiswayo, into engeyonto iphilayo enokunyusa ukumelana kwefilimu kwi-viscosity. Abanye abathengi bahlala befumanisa ukuba iileya ezimbini zesingxobo zibonakala zimfiliba phakathi kwazo, njengeeglasi ezimbini ezidibanayo. Uya kuqaphela ukuba kulula ukuyivula nokuyisula, nto leyo edla ngokungabikho kwezongezo zokuvula. Kwaye nabanye abenzi beefilimu abayisebenzisi.
Isongezo esigudileyo yi-Erucic acid amide, engumgubo omhlophe ohlala unamathela kwi-roller ye-lamination kunye ne-guide roller kwinkqubo ye-solvent-base laminating. Ukuba i-arhente egudileyo yongezwa ngexesha lenkqubo ye-solvent-free laminating, ezinye ziya kusasazeka ziye kumaleko we-corona njengoko ubushushu bokuphilisa bunyuka, nto leyo ebangela ukwehla kwamandla okuxobuka. Ifilimu yokuqala ye-lamination transparent PE exobulwe ngomhlophe, inokusulwa ngethishu. Kukho indlela yokuhlalutya nokuvavanya ukuba amandla okuxobuka ancitshisiwe achaphazeleka na kukwanda kwezongezo ezigudileyo, ukubeka ifilimu ye-laminate enamandla aphantsi kwi-oven kwi-80℃ imizuzu emihlanu, uze uvavanye amandla. Ukuba iyanda kakhulu, ngokusisiseko kugqitywa kwelokuba ukuncipha kwamandla okuxobuka kubangelwa yi-arhente egudileyo kakhulu.
Xa kuthelekiswa nokubuyela umva kwe-solvent-base lamination, indlela ye-solvent-free lamination ilula kakhulu ukufikelela ekudluliseleni nasekusasazekeni kwe-additives. Indlela eqhelekileyo yokugweba i-solvent free laminating rewind kukujonga ukuba zincinci kwaye zicocekile ngokwaneleyo ukuvumela ukuhamba okungcono kwesibini okugudileyo kwe-adhesives ezingena-solvent. Okukhona i-roller yefilimu ingena kuxinzelelo oluphezulu, i-additive etyibilikayo inokuthi ifudukele kumaleko we-laminated, okanye kumaleko wokuprinta. Ke ngoko, sihlala sididekile malunga nalo mba. Esinokukwenza kukunciphisa ubushushu bokuphilisa, ukunciphisa ubunzima be-coating, ukukhulula ifilimu, kunye nokongeza izongezo ezityibilikayo ngokuphindaphindiweyo. Kodwa ngaphandle kolawulo oluhle lwale nto ingasentla, i-adhesive kunzima ukuyinyanga kwaye igcina amanzi. Izongezo ezininzi kakhulu aziyi kuchaphazela kuphela amandla okuxobuka kwesikhwama seplastiki, kodwa zikwachaphazela nokusebenza kwayo kokuvala okushushu.
I-KANDA NEW MATERIALS ikhuphe uthotho lwezincamathelisi ukusombulula ezi ngxaki. I-WD8117A / B double component solvent-free adhesive yingcebiso elungileyo. Iqinisekiswe ngabathengi ixesha elide.
| Ulwakhiwo | I-coefficient yokuqala yokungqubana | I-coefficient elaminethiweyo yokungqubana |
| I-PET/PE30 | 0.1~0.15 | 0.12~0.16 |
I-WD8117A / B ingasetyenziselwa ukusombulula ingxaki yokungabi namandla okuxobuka kakuhle kunye nokusebenza kakuhle kokutywina ngobushushu ngenxa yezongezo ezigudileyo kakhulu zomphezulu ngaphandle kokufuna ukuba umenzi wefilimu yokuqala azinciphise.
Ukongeza, i-WD8117A/B inezinye iimpawu ezimbini:
1. Amandla okuxobuka e-OPP / AL / PE angaphezulu kwe-3.5 N, asondele okanye angaphezulu kunalawo ezinye izincamathelisi ze-laminating ezisekelwe kwisinyibilikisi.
2. Ukulungiswa ngokukhawuleza. Phantsi kweemeko ezicetyiswayo, ifilimu yokulaminetha inganciphisa ixesha lokubola malunga neeyure ezisi-8, nto leyo enyusa kakhulu ukusebenza kakuhle kwemveliso.
Ngamafutshane, ukumisela kokugqibela kwe-friction coefficient yefilimu edityanisiweyo kufuneka kusekelwe kwi-static friction coefficients phakathi kwefilimu kunye nepleyiti yentsimbi. Iingcamango eziphosakeleyo zokuba kunzima ukuvula isikhwama kuba akukho zongezo zaneleyo zokuthambisa kufuneka ziqatshelwe kwaye zilungiswe. Sinokufikelela kuphela ekuzinzeni nasekupakisheni iimveliso eziguquguqukayo ngokusebenzisa isishwankathelo ngasinye kunye nohlaziyo.
