Emkhakheni we-laminating engenazinyibilikisi, i-retorting yokushisa okuphezulu ibilokhu iyinkinga enzima eminyakeni embalwa edlule. Ngesikhathi kuthuthukiswa imishini, izinamathiseli kanye nobuchwepheshe, i-laminating engenazinyibilikisi yepulasitiki enepulasitiki engaphansi kuka-121℃ ithole ukusetshenziswa okukhulu phakathi kwabakhiqizi bokupakisha abaguquguqukayo. Ngaphezu kwalokho, inani lamafektri asebenzisa i-PET/AL, i-AL/PA kanye ne-Plastic/AL yokushintsha i-121℃ liyakhula.
Leli phepha lizogxila ekuthuthukisweni kwakamuva, amaphuzu okulawula ngesikhathi sokukhiqiza kanye nezitayela zesikhathi esizayo.
1. Intuthuko yakamuva
Amaphakethe okuguqula manje ahlukaniswe ngezinhlobo ezimbili zezingxenye, ipulasitiki/ipulasitiki kanye nepulasitiki/i-aluminium. Ngokwezidingo ze-GB/T10004-2008, inqubo yokuguqula ihlukaniswe njengezinga lokushisa eliphakeme kakhulu (100℃ - 121℃) kanye nezinga lokushisa eliphakeme (121℃ - 145℃). Njengamanje, i-laminating engenaso isinyibilikisi imboze ukwelashwa kokubulala amagciwane okungu-121℃ nangaphansi kuka-121℃.
Ngaphandle kwezinto ezijwayelekile ze-PET, AL, PA, RCPP, ezisetshenziselwa ama-laminate amathathu noma amane, ezinye izinto ezifana namafilimu e-aluminium acacile, i-PVC ephendulayo ziyavela emakethe. Nakuba kungekho ukukhiqizwa okukhulu kanye nokusetshenziswa, lezo zinto zidinga isikhathi esiningi kanye nokuhlolwa okwengeziwe ukuze zisetshenziswe kakhulu.
Njengamanje, i-glue yethu i-WD8262A/B inamakesi aphumelelayo asetshenziswa ku-substrate PET/AL/PA/RCPP, angafinyelela ku-121℃ aphendulayo. Ku-substrate yepulasitiki/yepulasitiki i-PA/RCPP, i-glue yethu i-WD8166A/B inokusetshenziswa okubanzi futhi inamakesi athuthukisiwe.
Iphuzu elinzima le-laminating engenaso isinyibilikisi, i-PET/Al ephrintiwe manje isixazululwa yi-WD8262A/B yethu. Sibambisene nabaphakeli bemishini abaningana, sayihlola futhi sayilungisa izikhathi eziyinkulungwane, futhi ekugcineni senza i-WD8262A/B ngokusebenza okuhle. Esifundazweni saseHunan, amakhasimende ethu anentshiseko enkulu kuma-laminate aphendulayo e-Aluminium, futhi kulula kakhulu ukuthi enze isivivinyo. Kwi-substrate ye-PET/AL/RCPP ephrintiwe, zonke izendlalelo zimbozwe nge-WD8262A/B. Kwi-PET/PA/AL/RCPP ephrintiwe, kusetshenziswa izendlalelo ze-PET/PA kanye ne-AL/RCPP ze-WD8262A/B. Isisindo se-coating singu-1.8 - 2.5 g/m2, futhi isivinini singaba ngu-100m/min – 120m/min.
Imikhiqizo engenazo izinyibilikisi zeKangda manje isifinyelele intuthuko enkulu ngaphansi kuka-128℃ futhi iyaqhubeka nokuba yinselele yokwelashwa kokushintshashintsha kwezinga lokushisa okungu-135℃ ngisho no-145 ℃. Ukumelana namakhemikhali nakho kuyacwaningwa.
ISIVIVINYO SOKUSEBENZA
| IMODELI | IZINTO EZINGAPHANSI | AMANDLA OKUKHUPHA NGEMVA KWE-121℃ UKUBUYISA |
| WD8166A/B | I-PA/RCPP | 4-5N |
| WD8262A/B | I-AL/RCPP | 5-6N |
| WD8268A/B | I-AL/RCPP | 5-6N |
| WD8258A/B | AL/NY | 4-5N |
Ubunzima:
Inkinga enkulu yokwenza izikhwama zokufaka i-aluminium ezinezingqimba ezine ukuthola inhlanganisela efanele yezinto ezahlukene, okuhlanganisa amafilimu, izinamathiseli, uyinki kanye nesinyibilikisi. Ikakhulukazi, ukukhiqiza i-PET/AL ephrintiwe ngokugcwele lolu ngqimba lwangaphandle lunzima kakhulu. Sasivame ukubhekana nalezi zimo lapho, lapho sithatha izinto ezivela kumakhasimende siziyisa elabhorethri yethu futhi sihlola zonke izinto okuhlanganisa nemishini, akukho phutha elitholakale. Kodwa-ke, lapho sihlanganisa zonke izinto, ukusebenza kwama-laminate kwakungagculisi. Kuphela uma bonke ubuchwepheshe, imishini, izinto zilawulwa ngokugcwele, i-substrate ingenziwa ngempumelelo. Enye ifektri ingenza le substrate akusho ukuthi noma ubani angaphumelela futhi.
2. Izindawo zokulawula ngesikhathi sokukhiqiza
1) Isisindo sokumboza singaba ngu-1.8 - 2.5 g/m2.
2) Umswakama ozungezile
Kunconywa ukuthi umswakama wegumbi ulawule phakathi kuka-40% - 70%. Amanzi aqukethwe emoyeni azohlanganyela ekusabeleni kwe-glue, umswakama ophezulu uzonciphisa isisindo sama-molecule se-glue futhi ulethe ukusabela okuncane, okuthonya ukusebenza kokumelana nokubuyela emuva.
3) Izilungiselelo ku-laminator
Ngokwemishini ehlukene, izilungiselelo ezifanele ezifana nokucindezela, ingcindezi, i-mixer kumele zihlolwe ukuze kutholakale ukusetshenziswa okufanele nokwenza ama-laminate abe yisicaba.
4) Izidingo zamafilimu
Ukuqina okuhle, inani elifanele le-dyne, ukuncipha kanye nokuqukethwe komswakama njll. konke kuyizinto ezidingekayo zokufaka i-laminating.
3. Izitayela zesikhathi esizayo
Njengamanje, ukusetshenziswa kwe-lamination engenaso i-solvent kusephaketheni eliguquguqukayo, elinomncintiswano omkhulu. Ngamaphuzu omuntu siqu, kunezindlela ezintathu zokuthuthukisa i-lamination engenaso i-solvent.
Okokuqala, imodeli eyodwa enezinhlelo zokusebenza eziningi. Umkhiqizo owodwa ungakha izisekelo eziningi zomkhiqizi wokupakisha oguquguqukayo, okungonga isikhathi esiningi, ukunamathelisa nokwandisa ukusebenza kahle.
Okwesibili, ukusebenza okuphezulu, okunikeza ukumelana okuphezulu kokushisa namakhemikhali.
Okokugcina, ukuphepha kokudla. Manje i-lamination engenazo izinyibilikisi inezingozi eziningi kune-lamination enesisekelo sezinyibilikisi njengoba inemikhawulo ethile emikhiqizweni esebenza kahle njengezikhwama eziphendulayo ezingu-135℃.
Ngaphezu kwakho konke, i-laminating engenazo izinyibilikisi ithuthuka ngokushesha, ubuchwepheshe obusha obuningi buvele. Esikhathini esizayo, i-laminating engenazo izinyibilikisi ingase ithathe indawo enkulu emakethe yokupakisha okuguquguqukayo kanye neminye imikhakha.
