Emkhakheni we-laminating-free laminating, ukubuyisela izinga lokushisa eliphezulu kube yinkinga enzima phakathi neminyaka embalwa edlule.Ngenkathi kanye nokuthuthukiswa kwemishini, izinto zokunamathisela kanye nobuchwepheshe, i-laminating-free laminating yepulasitiki enepulasitiki engaphansi kwe-121 ℃ retorting izuze ukusetshenziswa okuningi phakathi kwabakhiqizi bokupakisha abaguquguqukayo.Ngaphezu kwalokho, inani lezimboni eziqasha i-PET/AL, AL/PA kanye nePlastiki/AL ngo-121℃ liyakhula.
Leli phepha lizogxila ekuthuthukisweni kwakamuva, amaphuzu okulawula ngesikhathi sokukhiqiza kanye nezitayela zesikhathi esizayo.
1. Intuthuko yakamuva
Izikhwama ezibuyisela emuva manje zihlukaniswe ngezinhlobo ezimbili zama-substrates, ipulasitiki/ipulasitiki nepulasitiki/i-aluminium.Ngokuvumelana nezidingo ze-GB/T10004-2008, inqubo yokubuyisela ihlukaniswa njengamazinga okushisa aphakathi nendawo (100℃ – 121℃) kanye nezinga lokushisa eliphezulu(121℃ – 145℃) amazinga amabili.Okwamanje, i-laminating engancibilikiyo imboze u-121℃ nangaphansi kuka-121℃ ukwelashwa kokuvala inzalo.
Ngaphandle kwezinto ezijwayelekile ze-PET, AL, PA, RCPP, ezisetshenziselwa izendlalelo ezintathu noma ezine zamalaminate, ezinye izinto ezinjengamafilimu abonisa ngale, i-PVC ebuyiselayo ivela emakethe.Yize kungekho ukukhiqizwa nokusetshenziswa kwezinga elikhulu, lezo zinto zidinga isikhathi nokuhlolwa okwengeziwe ukuze zisetshenziswe kakhulu.
Njengamanje, ingcina yethu i-WD8262A/B inamacala ayimpumelelo afakwe ku-substrate PET/AL/PA/RCPP, engafinyelela ku-121℃ ukuphindaphinda.Okwepulasitiki/ipulasitiki engaphansi i-PA/RCPP, ingcina yethu i-WD8166A/B inokusebenza okubanzi namakesi athuthukisiwe.
Iphuzu eliqinile le-laminating-free laminating, i-PET/Al ephrintiwe manje isixazululwa yi-WD8262A/B yethu.Sabambisana nabahlinzeki bemishini eminingana, sayihlola futhi sayilungisa izikhathi eziyinkulungwane, futhi ekugcineni senza i-WD8262A/B ngokusebenza kahle.Esifundazweni sase-Hunan, amakhasimende ethu anomdlandla omkhulu kuma-laminates e-Aluminium retorting, futhi kulula kakhulu kuwo ukwenza isilingo.Ku-PET/AL/RCPP substrate ephrintiwe, zonke izendlalelo zimbozwe nge-WD8262A/B.Kuzendlalelo eziphrintiwe ze-PET/PA/AL/RCPP, PET/PA kanye ne-AL/RCPP zisetshenziswa i-WD8262A/B.Isisindo se-coating singaba ngu-1.8 - 2.5 g / m2, futhi ijubane licishe libe ngu-100m/min – 120m/min.
Imikhiqizo ye-Kangda engancibilikiyo manje isizuze inqubekelaphambili enkulu ngaphansi kuka-128 ℃ futhi igcina inselele ku-135 ℃ ngisho no-145 ℃ wokwelashwa okubuyisela izinga lokushisa eliphezulu.Ukumelana namakhemikhali nakho kungaphansi kocwaningo.
ISIVIVINYO SOKUSEBENZA
| INDLELA | SUBSTRATES | UKUQHULA AMANDLA NGEMVA KWE-121℃ UKUBUYISA |
| I-WD8166A/B | PA/RCPP | 4-5N |
| I-WD8262A/B | I-AL/RCPP | 5-6N |
| I-WD8268A/B | I-AL/RCPP | 5-6N |
| I-WD8258A/B | I-AL/NY | 4-5N |
Ubunzima:
Inkinga enkulu yokukhiqiza izikhwama ezine ze-aluminium retorting ukuthola inhlanganisela efanele yezinto ezihlukahlukene, okuhlanganisa amafilimu, izinto zokunamathisela, uyinki kanye ne-solvent.Ikakhulukazi, ukukhiqiza i-PET/AL ephrintiwe ngokugcwele lolu sendlalelo sangaphandle yikhona okunzima kakhulu.Sasivame ukubhekana nalawa macala okuthi, lapho sithatha izinto kumakhasimende siziyisa elabhorethri yethu futhi sihlola zonke izakhi kuhlanganisa nemishini, kungatholakali phutha.Kodwa-ke, lapho sihlanganisa zonke izakhi, ukusebenza kwama-laminates kwakunganelisi.Kuphela lapho bonke ubuchwepheshe, imishini, izinto zokwakha zilawulwa ngokugcwele, i-substrate ingenziwa ngempumelelo.Enye imboni ingenza le substrate akusho ukuthi noma ubani angathola impumelelo.
2. Lawula amaphuzu ngesikhathi sokukhiqiza
1) Isisindo se-coating sizungeze i-1.8 - 2.5 g / m2.
2) Umswakama ozungezile
Umswakama wegumbi uyaphakanyiswa ukuthi ulawule phakathi kuka-40% -70%.Amanzi aqukethwe emoyeni azobamba iqhaza ekuphenduleni kwe-adhesive, umswakama ophezulu uzonciphisa isisindo samangqamuzana okunamathisela futhi ulethe ukusabela okungaphansi, okuthonya ukusebenza kokumelana nokuphindaphinda.
3) Izilungiselelo ku-laminator
Ngokusho kwemishini ehlukene, izilungiselelo ezifanele ezifana nokungezwani, ingcindezi, i-mixer kufanele ihlolwe ukuze kutholwe uhlelo olufanele futhi kwenze ama-laminates flat.
4) Izidingo zamafilimu
Ukuhleleka okuhle, inani elifanele le-dyne, ukuncipha kanye nokuqukethwe komswakama njll. yizimo ezidingekayo zokubuyisela i-laminating.
3. Izitayela zesikhathi esizayo
Njengamanje, ukusetshenziswa kwe-lamination-free lamination kusekufakweni okuguquguqukayo, okunomncintiswano oshubile.Emaphuzwini omuntu siqu, kunezindlela ezi-3 zokuthi i-lamination engena-solvent ithuthuke.
Okokuqala, imodeli eyodwa enezinhlelo zokusebenza eziningi.Umkhiqizo owodwa ungakha ama-substrates amaningi omkhiqizi wokupakisha oguquguqukayo, ongasindisa isikhathi esiningi, ukunamathela futhi andise ukusebenza kahle.
Okwesibili, ukusebenza okuphezulu, okunikeza ukumelana okuphezulu kokushisa namakhemikhali.
Okokugcina, ukuphepha kokudla.Manje i-lamination-free-free lamination inezingozi eziningi kune-solvent-base lamination njengoba inemikhawulo ethile emikhiqizweni yokusebenza okuphezulu njengezikhwama ezibuyisela emuva ezingu-135℃.
Ngaphezu kwakho konke, i-laminating engena-solvent ikhula ngokushesha, ubuchwepheshe obusha obuningi buphumile.Ngokuzayo, i-laminating-free laminating ingase ithathe i-akhawunti enkulu yemakethe yokupakisha okuguquguqukayo nezinye izinkambu.
