Ensimini ye-solvent-free laminaming, Ukuphindaphinda okuphezulu kokunye kube yinkinga enzima phakathi neminyaka embalwa edlule. Ngenkathi kanye nentuthuko yemishini, enamathela kanye nobuchwepheshe, i-solvent-free laminating yepulasitiki ngaphansi kwepulasitiki ngaphansi kwe-121 ℃ Ukuphinda uthathe izicelo zithole ukusetshenziswa kwezicelo eziningi eziguqukayo. Ngaphezu kwalokho, inani lamafektri aqasha isilwane / i-al, al / pa kanye neplastiki / al for 121 al Ukuphinda usebenze.
Leli phepha lizogxila entuthukweni yakamuva, lawula amaphuzu ngesikhathi sokukhiqiza nekusasa.
1. Ukuthuthuka kwakamuva
Ukuphephisa izikhwama manje kuhlukaniswe ngezinhlobo ezimbili zezigatshana, ipulasitiki / ipulasitiki nepulasitiki / i-aluminium. Ngokusho kwezidingo ze-GB / T10004-2008, inqubo yokuphinda ihlukaniswe ihlukaniswa njenge-Half-high Card yokushisa (100 ℃ - 121 ℃) kanye nokushisa okuphezulu (121 ℃ - 145 ℃) Izindinganiso ezimbili. Njengamanje, i-solvent-free laminating ihlanganiswe ngo-121 ℃ nangaphansi kwe-121 ℃ ukwelashwa inzalo.
Ngaphandle kwezinto ezijwayelekile zezinto ezijwayelekile, i-Al, Pa, RCPP, ezisetshenziselwa izingqimba ezintathu noma ezine ezihlangene, ezinye izinto ezifana namafilimu asobala, abuyele ePVC avele emakethe. Yize kungekho ukukhiqiza okuphezulu kanye nesicelo, lezo zinto zokwakha zidinga isikhathi esithe xaxa nokuhlolelwa okuningi kokusetshenziswa okukhulu.
Njengamanje, i-adhesive WD8262A / B inamacala aphumelelayo asetshenzisiwe kwi-substrate pet / al / PA / RCPP, engafinyelela ku-121 ℃ Ukuphinda uphinde uphinde ufike ekuphindiseni. Ngeplastiki / ipulasitiki substrate PA / RCPP, i-Adhesive WD8166A / B ine-application ebanzi futhi ithuthukise amacala.
Iphuzu elinzima le-solvent-free laminating, ephrintiwe pet / al manje selixazululwe yi-WD8262A / B yethu. Sasebenzisana nabahlinzeki ngemishini, bahlola futhi basilungisa amahlandla ayinkulungwane, futhi ekugcineni benze i-WD8262A / B ngokusebenza okuhle. EsiFundazweni seHunan, amakhasimende ethu anomdlandla ophakeme ku-aluminium aphendule ama-laminates, futhi kulula kakhulu ngawo ukwenza icala. Okwe-PITED PET / Al / RCPP Substrate, zonke izingqimba zihlanganiswe ne-WD8262A / B. OkwePrintiwe Pet / PA / Al / RCPP, izingqimba ze-Pet / PA ne-AL / RCPP zisetshenziswa i-WD8262A / B. Isisindo se-coating sizungeze i-1.8 - 2.5 g / m2, futhi ijubane liseduze kwe-100m / min - 120m / min.
Imikhiqizo ye-kangda solvent-free manje isithole inqubekela phambili enkulu ngaphansi kwe-128 ℃ futhi iqhubeke inselele ngo-135 ℃ ngisho nokwelashwa okuphezulu kokushisa okuphezulu. Ukuphikiswa kwamakhemikhali nakho kungaphansi kocwaningo.
Ukuhlolwa kokusebenza
| Isifanekiso | Substrates | Ukukhonkotha Amandla Ngemuva Kwe-121℃ Ukuphindisela |
| 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:
Inkinga enkulu yokwakha izikhwama ezine-aluminium ezibuyisanayo ze-aluminium ukuthola inhlanganisela efanelekile yezinto ezahlukahlukene, kufaka phakathi amafilimu, anamathela, uyinki futhi i-solvent. Ikakhulu, ukukhiqiza izilwane eziphrintiwe ngokugcwele / i-AL lokhu ungqimba lwangaphandle olunzima kakhulu. Sasivame ukubhekana nalezi zimo ukuthi, lapho sithatha izinto ezivela kumakhasimende siye elabhoratri lethu futhi sahlolelwa zonke izinto kubandakanya imishini, akukho iphutha elitholakele. Kodwa-ke, lapho sihlanganisa zonke izinto, ukusebenza kwama-laminates bekungagculisi. Kuphela lapho wonke ama-technologies, imishini, izinto zokwakha zilawulwa ngokuphelele, i-substrate ingahle yenziwe ngempumelelo. Enye ifektri ingenza le substrate akusho ukuthi noma ngubani angathola nempumelelo.
2. Lawula amaphuzu ngesikhathi sokukhiqiza
1) Isisindo se-coating sizungeze i-1.8 - 2.5 g / m2.
2) umswakama ozungezile
Umswakama wegumbi uphakanyiswa ukulawula phakathi kwama-40% - 70%. Amanzi aqukethe emoyeni azobamba iqhaza ukusabela kokunamathela, umswakama ophezulu azonciphisa isisindo se-molecular sokunamathela futhi alethe okunye ukusabela, ukuthonya ukusebenza kokuziphindisela.
3) Izilungiselelo ku-laminator
Ngokusho kwemishini ehlukene, izilungiselelo ezifanele ezinjengokungezwani, ingcindezi, i-mixer kumele ihlolwe ukuthola uhlelo lokusebenza olufanele futhi lwenze ama-laminates.
4) Izidingo zamafilimu
I-Planness enhle, inani elifanele le-dyne, i-shrinkage kanye nomswakama njll. Yonke imibandela edingekayo yokuphinda uthathe ama-laminating.
3. Izitayela zesikhathi esizayo
Njengamanje, ukusetshenziswa kwe-solvent-free lamination kusendaweni eguquguqukayo, enomncintiswano onolaka. Ngamaphuzu akho, kunezindlela ezi-3 zokubuyiselwa okumahhala kwe-solvent.
Okokuqala, imodeli eyodwa enezicelo eziningi. Umkhiqizo owodwa ungakhiqiza ama-substrates amaningi womkhiqizi oguqukayo wokupakisha, ongagcina isikhathi esiningi, anamathele futhi andise ukusebenza kahle.
Okwesibili, ukusebenza okuphezulu, okunikeza ukumelana okuphezulu kokushisa namakhemikhali.
Okokugcina, ukuphepha kokudla. Manje ukugqanyiswa kwamahhala kwe-solvent kunezingozi eziningi kune-solvent-base isimangaliso njengoba inemikhawulo emikhiqizweni ephezulu yokusebenza efana ne-135 ℃ yokubuyisa izikhwama.
Ngaphezu kwakho konke, i-solvent-free lamimiating ikhula ngokushesha, ubuchwepheshe obusha obuningi buphume. Esikhathini esizayo, i-solvent-free laminating ingathatha i-akhawunti enkulu yemakethe yokufaka okuguqukayo kanye nezinye izinkambu.
