I-solvent-free lamination ikhulile kwimarike, ikakhulu ngenxa yeenzame zokupakisha amashishini kunye nababoneleli bezinto eziphathekayo, ngakumbi iteknoloji ye-aluminiyam ecocekileyo ye-lamination ye-retorting iye yanda kakhulu, kwaye ithathe inyathelo elikhulu phantsi kweemeko zokusingqongileyo zokutshintsha i-solvent yendabuko- isiseko se-lamination kunye ne-extruded lamination production.Amashishini okupakisha athwaxwa ziingxaki ezahlukeneyo zomgangatho ngenxa yeemeko ezahlukeneyo zeemveliso kwisixhobo, ukusebenza, imathiriyeli ekrwada, itekhnoloji esemgangathweni kunye nokusetyenziswa.Eli phepha liza kuthetha ngengxaki ekhoyo, eyile, ukukwazi ukuvula isingxobo kunye nokuguda kwayo.
Ngokomzekelo, ifilimu ye-polyethylene eqhelekileyo yamanqanaba amathathu yenziwe ngumaleko we-corona, umaleko ophakathi osebenzayo kunye nomgangatho ophantsi we-thermal seal.Ngokuqhelekileyo, i-additives yokuvula kunye ne-smooth yongezwa kwi-hot seal layer.I-additive e-Smooth idluliselwa phakathi kwe-3 umaleko, kunye nokuvula ukongezwa akunjalo.
Njengesixhobo sokutywina okutshisayo, ii-additives zokuvula kunye nezigudileyo ziyimfuneko xa uvelisa i-flexible packaging composite.Zahluke kakhulu, kodwa uninzi lwabavelisi bokupakisha abaqondi ukuba ziyafana.
Isihlomelo sokuvula jikelele sifumaneka kurhwebo lwesilicon diokside, eyinto engaphiliyo enokonyusa ukuxhathisa kwefilimu kwi-viscosity.Abanye abathengi basoloko befumanisa ukuba iileya ezimbini zesingxobo zibonakala zimfiliba phakathi kwazo, njengeeglasi ezimbini ezithelelanayo.Uyakuqaphela ukuba igudile ukuvula kunye nokusula, okuhlala kunqongophele ekuvuleni izongezo.Kwaye nabanye abenzi befilimu abayisebenzisi.
I-additive jikelele egudileyo i-Erucic acid amide, eyimpuphu emhlophe ehlala ibambelele kwi-lamination roller kunye ne-guide roller kwinkqubo ye-solvent-base laminating.Ukuba ukongezwa kwe-arhente egudileyo yongezwa ngexesha lenkqubo yokunyibilikisa enganyibilikiyo, abanye baya kusasazwa kumaleko e-corona njengoko ubushushu bonyango bunyuka, okukhokelela ekunciphiseni amandla okuxobula.Ifilimu ye-PE ye-lamination ye-lamination yasekuqaleni ehlutshiwe ngomhlophe, inokosulwa ngeethishu.Kukho indlela yokuhlalutya kunye nokuvavanya ukuba amandla ancitshisiweyo ahlanjululwayo achatshazelwa kukugqithisa kwezongezo ezigudileyo, ukubeka ifilimu ye-laminate yamandla aphantsi kwi-oven e-80 ℃ imizuzu emihlanu, kwaye emva koko uvavanya amandla.Ukuba inyuka kakhulu, kugqitywa ukuba ukuncitshiswa kwamandla okuxobula kubangelwa i-arhente egudileyo kakhulu.
Xa kuthelekiswa ne-rewind ye-solvent-base lamination, indlela ye-solvent-free lamination ilula kakhulu ukufezekisa ukuhanjiswa okongeziweyo kunye nokusabalalisa.Indlela eqhelekileyo yokugweba i-solvent free laminating rewind kukukhangela ukuba i-compact kwaye icocekile ngokwaneleyo ukuze ivumele ukuhamba kakuhle kwesekondari ye-adhesives engenazinyibilikisi.Uxinzelelo oluphezulu i-roller yefilim ingena, kokukhona isongezo esimtyibilizi sinokuthi sifudukele kumaleko alaminated, okanye nakwi-printing layer.Ngoko ke, sihlala sididekile malunga nalo mba.Into esinokuyenza kukunciphisa ubushushu bokunyanga, ukuthoba ubunzima bokugquma, ukukhulula ifilimu, kwaye songeze izongezo ezigudileyo ngokuphindaphindiweyo.Kodwa ngaphandle kolawulo olulungileyo olungentla, i-adhesive inzima ukunyanga kwaye ibamba amanzi.Izongezo ezininzi aziyi kuchaphazela kuphela amandla okuxobula isingxobo seplastiki, kodwa zikwachaphazela ukusebenza kwayo kokutywinwa okushushu.
I-KANDA NEW MATERIALS ikhuphe uluhlu lwee-adhesives ukusombulula ezi ngxaki.I-WD8117A / B i-adhesive ephindwe kabini ye-solvent-free adhesive yingcebiso elungileyo.Iqinisekisiwe ngabathengi ixesha elide.
| Ulwakhiwo | I-coefficient yoqobo yokukhuhlana | I-coefficient ye-friction ene-laminated |
| I-PET/PE30 | 0.1~0.15 | 0.12~0.16 |
I-WD8117A / B ingasetyenziselwa ukusombulula ingxaki yokungabi namandla okuxobula kunye nokusebenza kokutywinwa kwe-thermal ngenxa yezongezo ezigudileyo zomphezulu ngaphandle kokufuna umenzi wefilimu wokuqala ukuba anciphise.
Ukongeza, i-WD8117A/B inezakhiwo ezimbini ezingakumbi:
1. Amandla e-peelling ye-OPP / AL / PE ingaphezulu kwe-3.5 N, isondele okanye iphezulu kunezinye i-solvent-base-laminating adhesives.
2. Ukunyanga ngokukhawuleza.Phantsi kweemeko ezicetyisiweyo, ifilimu yokulayita inokunciphisa ixesha lokunyanga malunga neeyure ezi-8, eziphakamisa kakhulu ukusebenza kwemveliso.
Ukushwankathela, ukumiselwa kokugqibela kwe-friction coefficient yefilimu edibeneyo kufuneka isekelwe kwi-static friction coefficients phakathi kwefilimu kunye nepleyiti yensimbi.Iingcamango ezingezizo zokuba kunzima ukuvula isingxobo ngenxa yokuba akukho zongezelelo zaneleyo zokugudisa kufuneka ziqatshelwe kwaye zilungiswe.Sinokufikelela kuphela ukuzinza kunye neemveliso zokupakisha eziguquguqukayo eziphezulu ngesishwankathelo ngasinye kunye nohlaziyo.
