Kwintsimi ye-laminating-free laminating, ukubuyiswa kobushushu obuphezulu kuye kwaba yingxaki enzima kwiminyaka embalwa edlulileyo.Ngelixa kunye nophuhliso lwezixhobo, izinto zokuncamathelisa kunye netekhnoloji, i-laminating-free laminating yeplastiki eneplastiki ephantsi kwe-121 ℃ i-retorting ifumene isicelo esikhulu phakathi kwabavelisi bokupakisha abaguquguqukayo.Ngaphezu koko, inani lemizi-mveliso eqesha i-PET/AL, AL/PA kunye nePlastiki/AL ye-121℃ yokubuyisela liyakhula.
Eli phepha liza kugxininisa kuphuhliso lwamva nje, amanqaku olawulo ngexesha lokuvelisa kunye neendlela ezizayo.
1. Uphuhliso lwamva nje
Iipowutshi ezibuyiselayo ngoku zohlulwe zibe ziindidi ezimbini zesubstrates, iplastiki/iplastiki kunye neplastiki/ialuminiyam.Ngokweemfuno ze-GB/T10004-2008, inkqubo yokubuyisela ihlelwa njengesiqingatha sobushushu obuphezulu (100℃ – 121℃) kunye nobushushu obuphezulu (121℃ – 145℃) imigangatho emibini.Okwangoku, i-laminating-free laminating igqume i-121℃ nangaphantsi kwe-121℃ unyango lokuvala inzala.
Ngaphandle kwezixhobo eziqhelekileyo ze-PET, AL, PA, RCPP, ezisetyenziselwa iileyiti ezintathu okanye ezine ze-laminates, ezinye izinto ezifana neefilimu ezicacileyo ze-aluminized, ezibuyisela i-PVC zivela kwimarike.Ngelixa kungekho mveliso inkulu kunye nokusetyenziswa, ezo zixhobo zifuna ixesha elingakumbi kunye novavanyo olungakumbi lokusetyenziswa okukhulu.
Okwangoku, i-adhesive yethu i-WD8262A/B ineemeko eziyimpumelelo ezifakwe kwi-substrate PET/AL/PA/RCPP, enokufikelela kwi-121℃ retorting.Kwiplastiki / i-substrate yeplastiki ye-PA / RCPP, i-adhesive WD8166A / B yethu inesicelo esibanzi kunye neemeko eziphuhlisiwe.
Inqaku elinzima le-laminating-free laminating, eprintiweyo ye-PET / Al ngoku ixazululwe yi-WD8262A / B yethu.Siye sasebenzisana nababoneleli bezixhobo ezininzi, savavanya kwaye sahlengahlengisa amaxesha ayiwaka, kwaye ekugqibeleni senza i-WD8262A/B ngokusebenza kakuhle.Kwiphondo laseHunan, abathengi bethu banenzondelelo enkulu kwi-Aluminiyam ebuyisela i-laminates, kwaye kulula ngakumbi ukuba benze ulingo.Kwi-substrate ye-PET/AL/RCPP eprintiweyo, zonke iileya zigqunywe nge-WD8262A/B.Kwi-PET/PA/AL/RCPP eprintiweyo, i-PET/PA kunye ne-AL/RCPP layers zisetyenziswa i-WD8262A/B.Ubunzima bokugquma bujikeleze i-1.8 - 2.5 g / m2, kunye nesantya sijikeleze i-100m / min - 120m / min.
Iimveliso ze-solvent-free ze-Kangda ngoku ziphumelele inkqubela enkulu phantsi kwe-128 ℃ kwaye zigcine umngeni kwi-135 ℃ nakwi-145 ℃ yonyango olubuyisela ubushushu obuphezulu.Ukumelana nemichiza kuphantsi kophando.
UVAVANYO LOKUSEBENZA
| UMZEKELO | I-SUBSTRATES | UKUQHULA AMANDLA EMVA KWE-121℃ UKUBUYISELWA |
| WD8166A/B | PA/RCPP | 4-5N |
| WD8262A/B | AL/RCPP | 5-6N |
| WD8268A/B | AL/RCPP | 5-6N |
| WD8258A/B | AL/NY | 4-5N |
Ubunzima:
Ingxaki ephambili yokuvelisa iipowutshi zokubuyisela i-aluminiyam ezine-layer kukufumana indibaniselwano efanelekileyo yezinto ezahlukeneyo, kubandakanywa iifilimu, i-adhesives, inki kunye ne-solvent.Ngokukodwa, ukuvelisa i-PET/AL eprintwe ngokupheleleyo le maleko yangaphandle yeyona nto inzima.Sasidla ngokujongana nezi meko ukuba, xa sithatha izinto kubathengi sisiya kwilabhoratri yethu kwaye sivavanya zonke izinto ezibandakanya izixhobo, akukho siphoso sifunyenweyo.Nangona kunjalo, xa sidibanisa zonke izinto, ukusebenza kwe-laminates kwakunganelisi.Kuphela xa zonke iteknoloji, izixhobo, izixhobo ziphantsi kolawulo ngokupheleleyo, i-substrate ingenziwa ngempumelelo.Omnye umzi-mveliso unokwenza le substrate ayithethi ukuba nabani na unokuphumelela impumelelo.
2. Amanqaku okulawula ngexesha lokwenziwa
1) Ubunzima bokugubungela bujikeleze i-1.8 - 2.5 g / m2.
2) Ukufuma okujikelezayo
Ukufuma kwegumbi kucetyiswa ukuba kulawulwe phakathi kwe-40% - 70%.Amanzi aqulethwe emoyeni aya kuthatha inxaxheba kwi-reaction of adhesive, ukufuma okuphezulu kuya kunciphisa ubunzima be-molecular of adhesive kunye nokuzisa ezinye ii-sub-reactions, ezichaphazela ukusebenza kwe-retorting resistance.
3) Izicwangciso kwi-laminator
Ngokutsho koomatshini abahlukeneyo, izicwangciso ezifanelekileyo ezifana noxinzelelo, uxinzelelo, umxube kufuneka uvavanywe ukufumana isicelo esifanelekileyo kwaye wenze i-laminates flat.
4) Iimfuno zeefilimu
I-planeness elungileyo, ixabiso elifanelekileyo le-dyne, i-shrinkage kunye nomxholo womswakama njl. zonke ziimeko eziyimfuneko zokubuyisela i-laminating.
3. Iintsingiselo zexesha elizayo
Okwangoku, ukusetyenziswa kwe-solvent-free lamination kwi-flexible packaging, enokhuphiswano olunzima.Kumanqaku omntu, kukho iindlela ezi-3 zokuphuhlisa i-lamination-free lamination.
Okokuqala, imodeli enye enezicelo ezininzi.Imveliso enye inokuvelisa uninzi lwee-substrates zomenzi wokupakisha oguquguqukayo, onokugcina ixesha elininzi, ukuncamathelisa kunye nokwandisa ukusebenza kakuhle.
Okwesibini, ukusebenza okuphezulu, okunika ukuchasana okuphezulu kobushushu kunye neekhemikhali.
Okokugqibela, ukhuseleko lokutya.Ngoku i-solvent-free lamination inemingcipheko engaphezu kwe-solvent-base lamination njengoko inezithintelo ezithile kwiimveliso zokusebenza eziphezulu ezifana ne-135 ℃ yokubuyisela ingxowa.
Ngaphezu kwakho konke, i-laminating-free laminating ikhula ngokukhawuleza, ngakumbi nangakumbi itekhnoloji entsha iphumile.Kwixesha elizayo, i-laminating-free laminating ingathatha i-akhawunti enkulu yemarike yokupakishwa okuguquguqukayo kunye nezinye iindawo.
