Chidule: Pepalali likufufuza vuto la ma white point la mafilimu ophatikizika a PET/VMCPP ndi PET/VMPET/PE akaphatikizidwa, ndikupereka mayankho oyenera.
Filimu yopangidwa ndi aluminiyamu ndi zinthu zofewa zopaka zokhala ndi "luster ya aluminiyamu" yopangidwa ndi mafilimu opangidwa ndi aluminiyamu (nthawi zambiri VMPET/VMBOPP, VMCPP/VMPE, ndi zina zotero, zomwe VMPET ndi VMCPP ndizomwe zimagwiritsidwa ntchito kwambiri) ndi mafilimu owonekera apulasitiki. Imagwiritsidwa ntchito popaka chakudya, zinthu zaumoyo, zodzoladzola, ndi zinthu zina. Chifukwa cha kunyezimira kwake kwachitsulo, kusavuta, mtengo wotsika, komanso magwiridwe antchito abwino otchinga, yagwiritsidwa ntchito kwambiri (makhalidwe abwino otchinga kuposa mafilimu opangidwa ndi pulasitiki, otsika mtengo komanso opepuka kuposa mafilimu opangidwa ndi aluminiyamu-pulasitiki). Komabe, madontho oyera nthawi zambiri amapezeka popanga mafilimu opangidwa ndi aluminiyamu. Izi zimawonekera makamaka muzinthu zopangidwa ndi mafilimu opangidwa ndi PET/VMCPP ndi PET/VMPET/PE.
1, Zomwe zimayambitsa ndi zothetsera mavuto a "madontho oyera"
Kufotokozera za chochitika cha "malo oyera": Pali madontho oyera oonekera bwino pa mawonekedwe a filimu yophatikizika, omwe amatha kugawidwa mwachisawawa komanso kukula kofanana. Makamaka pa mafilimu ophatikizika osasindikizidwa ndi inki yoyera yonse kapena mafilimu ophatikizika a inki yowala, ndizodziwikiratu.
1.1 Kusakwanira kwa mphamvu ya pamwamba pa aluminiyamu yophimba mbali ya aluminiyamu.
Kawirikawiri, kuyesa mphamvu ya pamwamba kuyenera kuchitika pamwamba pa korona ya filimu yomwe imagwiritsidwa ntchito isanayambe kupangidwa, koma nthawi zina kuyesa kwa chophimba cha aluminiyamu kumanyalanyazidwa. Makamaka pa mafilimu a VMCPP, chifukwa cha kuthekera kwa mvula ya zowonjezera zazing'ono mu filimu ya CPP, pamwamba pa aluminiyamu yophimbidwa ndi mafilimu a VMCPP omwe amasungidwa kwa nthawi yayitali amakhala ndi mphamvu yosakwanira.
1.2 Kusalinganika bwino kwa guluu
Magulu omatira okhala ndi zosungunulira ayenera kusankha kuchuluka kwa yankho logwira ntchito bwino malinga ndi buku la malangizo kuti atsimikizire kuti guluu ndi wabwino kwambiri. Ndipo kuwongolera kuyesa kukhuthala kuyenera kuchitika panthawi yopanga zinthu zosiyanasiyana. Pamene kukhuthala kukuwonjezeka kwambiri, zosungunulira ziyenera kuwonjezedwa nthawi yomweyo. Makampani omwe ali ndi vuto amatha kusankha zida zomatira zodzipangira zokha. Kutentha koyenera kwa zomatira zopanda zosungunulira kuyenera kusankhidwa malinga ndi buku la malangizo. Kuphatikiza apo, poganizira nkhani ya nthawi yoyambitsa yopanda zosungunulira, patatha nthawi yayitali, guluu mu roller yoyezera iyenera kutulutsidwa munthawi yake.
1.3 Njira yoipa yopangira zinthu zosiyanasiyana
Pa kapangidwe ka PET/VMCPP, chifukwa cha kukhuthala kochepa komanso kufalikira kosavuta kwa filimu ya VMCPP, kuthamanga kwa roller ya lamination sikuyenera kukhala kwakukulu kwambiri panthawi ya lamination, ndipo kuthamanga kwa ma winding sikuyenera kukhala kwakukulu kwambiri. Komabe, pamene kapangidwe ka PET/VMCPP ndi kophatikizana, chifukwa chakuti filimu ya PET ndi filimu yolimba, ndibwino kuwonjezera kuthamanga kwa roller ya laminating ndi kuthamanga kwa ma winding moyenera panthawi ya composite.
Magawo ofanana a njira yopangira zinthu ayenera kupangidwa kutengera momwe zida zopangira zinthuzo zilili pamene mapangidwe osiyanasiyana a aluminiyamu ndi opangidwa ndi zinthu zosiyanasiyana.
1.4 Zinthu zakunja zomwe zimalowa mu filimu yosakanikirana zimayambitsa "madontho oyera"
Zinthu zakunja makamaka zimakhala ndi fumbi, tinthu ta rabala, kapena zinyalala. Fumbi ndi zinyalala zimachokera makamaka ku workshop, ndipo nthawi zambiri zimachitika ngati ukhondo wa workshop ndi woipa. Tinthu ta rabala zimachokera makamaka ku ma disc a rabala, ma coating roller, kapena ma bonding roller. Ngati chomera chophatikizana si malo ochitira workshop opanda fumbi, chiyeneranso kuyesetsa kuonetsetsa kuti workshop yophatikizana ndi yoyera komanso yoyera, kuyika zida zochotsera fumbi kapena zosefera (chipangizo chophikira, guide roller, chipangizo chogwirizanitsa ndi zina) kuti ziyeretsedwe. Makamaka chophikira, scraper, flattening roller, ndi zina zotero ziyenera kutsukidwa nthawi zonse.
1.5 Chinyezi chambiri mu workshop yopangira zinthu chimabweretsa "madontho oyera"
Makamaka nthawi yamvula, pamene chinyezi cha workshop chili ≥ 80%, filimu yopangidwa ndi zinthu zosiyanasiyana imakhala ndi vuto la "madontho oyera". Ikani choyezera kutentha ndi chinyezi mu workshop kuti mulembe kusintha kwa kutentha ndi chinyezi, ndikuwerengera mwayi woti madontho oyera awonekere. Makampani omwe ali ndi vuto lililonse angaganizire zoyika zida zochotsera chinyezi. Pazinthu zopangidwa ndi zinthu zosiyanasiyana zomwe zili ndi zinthu zabwino zotchinga, ndikofunikira kuganizira zoyimitsa kupanga kapena kupanga zinthu zopangidwa ndi zinthu zosiyanasiyana zokhala ndi gawo limodzi kapena zingapo. Kuphatikiza apo, pamene mukutsimikizira kuti guluu likugwira ntchito bwino, tikukulimbikitsani kuchepetsa kuchuluka kwa mankhwala ochiritsira omwe amagwiritsidwa ntchito moyenera, nthawi zambiri ndi 5%.
1.6 Pamwamba pa guluu
Ngati palibe zolakwika zoonekeratu zomwe zapezeka ndipo vuto la "madontho oyera" silingathe kuthetsedwa, njira yophikira mbali ya aluminiyamu ikhoza kuganiziridwa. Koma njira imeneyi ili ndi zoletsa zazikulu.Makamaka pamene chophimba cha aluminiyamu cha VMCPP kapena VMPET chikutenthedwa ndi kutentha ndi kupsinjika mu uvuni, chimakhala chovuta kusinthasintha, ndipo njira yopangira zinthu iyenera kusinthidwa. Kuphatikiza apo, mphamvu ya peel ya aluminiyamu ikhoza kuchepa.
1.7 Kufotokozera kwapadera kwa momwe zinthu sizinali zachilendo zitatha, koma "madontho oyera" adawonekera pambuyo pa kukhwima:
Vuto lamtunduwu limapezeka kawirikawiri m'mapangidwe a nembanemba yokhala ndi zinthu zabwino zotchinga. Pa kapangidwe ka PET/VMCPP ndi PET/VMPET/PE, ngati kapangidwe ka nembanemba ndi kokhuthala, kapena mukamagwiritsa ntchito mafilimu a KBOPP kapena KPET, zimakhala zosavuta kupanga "madontho oyera" mutakalamba.
Mafilimu okhala ndi mipanda yolimba kwambiri m'nyumba zina nawonso amakhala ndi vuto lomweli. Zitsanzo zimaphatikizapo kugwiritsa ntchito zojambulazo zokhuthala za aluminiyamu kapena mafilimu opyapyala monga KNY.
Chifukwa chachikulu cha "malo oyera" awa ndikuti pali kutuluka kwa mpweya mkati mwa nembanemba yosakanikirana. Mpweya uwu ukhoza kukhala kufalikira kwa zosungunulira zotsalira kapena kufalikira kwa mpweya wa carbon dioxide wopangidwa ndi momwe zimakhalira pakati pa chotsukira ndi nthunzi ya madzi. Mpweya ukasefukira, chifukwa cha mawonekedwe abwino a filimu yosakanikirana, sungatulutsidwe, zomwe zimapangitsa kuti "malo oyera" (thovu) awonekere mu gawo lophatikizana.
Yankho: Mukaphatikiza guluu pogwiritsa ntchito zosungunulira, magawo a ndondomeko monga kutentha kwa uvuni, kuchuluka kwa mpweya, ndi kupanikizika koyipa ziyenera kukhazikitsidwa bwino kuti zitsimikizire kuti palibe zosungunulira zotsalira mu guluu. Yang'anirani chinyezi mu workshop ndikusankha njira yophimba guluu yotsekedwa. Ganizirani kugwiritsa ntchito chotsukira chomwe sichipanga thovu. Kuphatikiza apo, mukamagwiritsa ntchito zosungunulira pogwiritsa ntchito zosungunulira, ndikofunikira kuyesa kuchuluka kwa chinyezi mu zosungunulira, ndi kufunikira kwa kuchuluka kwa chinyezi ≤ 0.03%.
Zomwe zili pamwambapa ndi chiyambi cha "madontho oyera" m'mafilimu ophatikizika, koma pali zifukwa zosiyanasiyana zomwe zingayambitse mavuto otere pakupanga kwenikweni, ndipo ndikofunikira kupanga zigamulo ndi kusintha kutengera momwe zinthu zilili pakupanga kwenikweni.
