Kwicandelo le-laminating engenazinyibilikisi, i-retorting enobushushu obuphezulu ibe yingxaki enzima kwiminyaka embalwa edlulileyo. Ngelixa kunye nophuhliso lwezixhobo, izincamathelisi kunye netekhnoloji, i-laminating engenazinyibilikisi yeplastiki eneplastiki engaphantsi kwe-121℃ ifumene ukusetyenziswa kakhulu phakathi kwabavelisi bokupakisha abaguquguqukayo. Ngaphezu koko, inani leefektri ezisebenzisa i-PET/AL, i-AL/PA kunye nePlastic/AL kwi-retorting ye-121℃ liyanda.
Eli phepha liza kugxila kuphuhliso lwamva nje, iindawo zolawulo ngexesha lokuvelisa kunye neendlela zexesha elizayo.
1. Uphuhliso lwamva nje
Iipokotshi ezibuyisela umva ngoku zahlulwe zibe ziintlobo ezimbini ze-substrates, iplastiki/iplastiki kunye neplastiki/i-aluminium. Ngokweemfuno ze-GB/T10004-2008, inkqubo yokubuyisela umva ihlelwa njengeqondo lobushushu eliphakathi kwesiqingatha (100℃ – 121℃) kunye neqondo lobushushu eliphezulu (121℃ – 145℃) imigangatho emibini. Okwangoku, i-laminating engenasombululo igubungele unyango lokubulala iintsholongwane lwe-121℃ kunye nangaphantsi kwe-121℃.
Ngaphandle kwezinto eziqhelekileyo ze-PET, AL, PA, RCPP, ezisetyenziselwa iileya ezintathu okanye ezine ze-laminate, ezinye izinto ezifana neefilimu ezikhanyayo ze-aluminium, i-PVC ejikayo ziyavela kwimarike. Nangona kungekho mveliso inkulu kunye nokusetyenziswa, ezo zinto zifuna ixesha elingakumbi kunye novavanyo olungakumbi lokusetyenziswa okukhulu.
Okwangoku, i-adhesive yethu i-WD8262A/B ineekheyisi ezisebenza ngempumelelo kwi-substrate PET/AL/PA/RCPP, enokufikelela kwi-121℃ ejikajikayo. Kwi-substrate yeplastiki/yeplastiki i-PA/RCPP, i-adhesive yethu i-WD8166A/B inokusetyenziswa ngokubanzi kwaye iphuhlise iikheyisi.
Ingongoma enzima ye-laminating engenasombululo, i-PET/Al eprintiweyo ngoku isonjululwe yi-WD8262A/B yethu. Sisebenzisane nababoneleli bezixhobo abaliqela, sayivavanya saza sayilungisa izihlandlo eziliwaka, saza ekugqibeleni senza i-WD8262A/B ngokusebenza kakuhle. Kwiphondo laseHunan, abathengi bethu banomdla omkhulu kwi-laminates eziphendulayo ze-Aluminium, kwaye kulula ngakumbi kubo ukwenza uvavanyo. Kwi-substrate ye-PET/AL/RCPP eprintiweyo, zonke iileya zigqunywe nge-WD8262A/B. Kwi-PET/PA/AL/RCPP eprintiweyo, iileya ze-PET/PA kunye ne-AL/RCPP zisetyenziswa i-WD8262A/B. Ubunzima bokugquma bumalunga ne-1.8 - 2.5 g/m2, kwaye isantya simalunga ne-100m/min – 120m/min.
Iimveliso ezingenazinyibilikisi zaseKangda ngoku ziphumelele kakhulu phantsi kwe-128℃ kwaye zihlala zinzima kunyango lokubuyisela ubushushu obuphezulu kwi-135℃ nokuba yi-145℃. Ukumelana neekhemikhali nako kuphantsi kophando.
UVAVANYO LWENKQUBO
| IMODELI | IINGXELO EZINGAPHANTSI | AMANDLA OKUXOLISA EMVA KWE-121℃ UKUBUYISA |
| WD8166A/B | I-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 yokwenza iipokotshi ze-aluminium ezineeleya ezine kukufumana indibaniselwano efanelekileyo yezinto ezahlukeneyo, kuquka iifilimu, izincamathelisi, i-inki kunye nesinyibilikisi. Ingakumbi, ukuvelisa i-PET/AL eprintiweyo ngokupheleleyo le leya yangaphandle yeyona inzima kakhulu. Sasiqhele ukujongana nala matyala okuba, xa sithatha izinto kubathengi sizise kwilebhu yethu size sivavanye zonke izinto kuquka nezixhobo, akukho mpazamo ifunyenweyo. Nangona kunjalo, xa sidibanisa zonke izinto, ukusebenza kwee-laminates kwakunganeliseki. Kuphela xa zonke iiteknoloji, izixhobo, izinto zilawulwa ngokupheleleyo, i-substrate inokwenziwa ngempumelelo. Omnye umzi-mveliso unokwenza le substrate akuthethi ukuba nabani na angaphumelela.
2. Iindawo zokulawula ngexesha lokwenziwa
1) Ubunzima bokugquma bumalunga ne-1.8 - 2.5 g/m2.
2) Ukufuma okungqongileyo
Umswakama wegumbi ucetyiswa ukuba ulawule phakathi kwe-40% - 70%. Amanzi akwimo yomoya aya kuthatha inxaxheba kwimpendulo yeglue, umswakama ophezulu uya kunciphisa ubunzima beglue kwaye uzise ezinye iimpembelelo, nto leyo echaphazela ukusebenza kokumelana nokujika.
3) Useto kwi-laminator
Ngokweematshini ezahlukeneyo, kufuneka kuvavanywe useto olufanelekileyo olufana noxinzelelo, uxinzelelo, umxube ukuze kufunyanwe ukusetyenziswa okufanelekileyo nokwenza ii-laminates zibe zithe tyaba.
4) Iimfuno zeefilimu
Ukuqina kakuhle, ixabiso elifanelekileyo le-dyne, ukuncitshiswa kunye nomxholo wokufuma njl.njl. zonke ezi ziimeko eziyimfuneko zokurhoxisa i-laminating.
3. Iindlela zexesha elizayo
Okwangoku, ukusetyenziswa kwe-lamination engenasombululo kukwipakethe eguquguqukayo, enokhuphiswano olukhulu. Kwimiba yomntu, kukho iindlela ezi-3 zokuphuhlisa i-lamination engenasombululo.
Okokuqala, imodeli enye enezicelo ezininzi. Imveliso enye inokuvelisa uninzi lwezixhobo zomenzi wokupakisha oguquguqukayo, nto leyo enokonga ixesha elininzi, incamathisele kwaye yonyuse ukusebenza kakuhle.
Okwesibini, ukusebenza okuphezulu, okubonelela ngokumelana okuphezulu kobushushu kunye neekhemikhali.
Okokugqibela, ukhuseleko lokutya. Ngoku i-lamination engenazo izinyibilikisi ineengozi ezingaphezulu kune-lamination enesiseko se-solvent njengoko inemiqathango ethile kwiimveliso ezisebenza kakuhle ezifana neengxowa eziphendulayo ze-135℃.
Ngaphezu kwako konke, i-laminating engenasombululo iphuhliswa ngokukhawuleza, kwaye kuye kwavela ubuchwepheshe obutsha ngakumbi. Kwixesha elizayo, i-laminating engenasombululo inokuba yinxalenye enkulu yemarike yokupakisha okuguquguqukayo kunye nezinye iinkalo.
