Mafashoni atsopano aukadaulo wopaka laminating wopanda zosungunulira pa matumba obweza ndi Aluminium

Pankhani ya laminating yopanda zosungunulira, kutembenuza kutentha kwambiri kwakhala vuto lalikulu m'zaka zingapo zapitazi. Kuphatikiza pa kupanga zida, zomatira ndi ukadaulo, kutembenuza pulasitiki yopanda zosungunulira pogwiritsa ntchito pulasitiki pansi pa 121℃ kwagwiritsidwa ntchito kwambiri pakati pa opanga ma CD osinthasintha. Kuphatikiza apo, chiwerengero cha mafakitale omwe amagwiritsa ntchito PET/AL, AL/PA ndi Plastic/AL pakusintha kutentha kwa 121℃ chikukulirakulira.

Pepalali lidzayang'ana kwambiri pa chitukuko chaposachedwa, mfundo zowongolera panthawi yopanga zinthu komanso zomwe zikuchitika mtsogolo.

1. Zatsopano zomwe zachitika

Matumba obweza tsopano agawidwa m'mitundu iwiri ya zinthu zoyambira, pulasitiki/pulasitiki ndi pulasitiki/aluminium. Malinga ndi zofunikira za GB/T10004-2008, njira yobweza imagawidwa m'magulu awiri: kutentha kwa theka-kukwera (100℃ - 121℃) ndi kutentha kwakukulu (121℃ - 145℃). Pakadali pano, laminating yopanda zosungunulira yaphimba 121℃ ndi pansi pa 121℃.

Kupatula zinthu zodziwika bwino monga PET, AL, PA, RCPP, zomwe zimagwiritsidwa ntchito pa ma laminate atatu kapena anayi, zinthu zina monga mafilimu owonekera bwino a aluminiyamu, PVC yozungulira zimawonekera pamsika. Ngakhale kuti palibe kupanga ndi kugwiritsa ntchito kwakukulu, zinthuzo zimafuna nthawi yochulukirapo komanso mayeso ambiri kuti zigwiritsidwe ntchito kwambiri.

Pakadali pano, guluu wathu wa WD8262A/B uli ndi ma casing opambana omwe amagwiritsidwa ntchito pa substrate PET/AL/PA/RCPP, omwe amatha kufika 121℃ retort. Pa pulasitiki/pulasitiki substrate PA/RCPP, guluu wathu wa WD8166A/B umagwiritsidwa ntchito kwambiri ndipo umapanga ma casing.

Mfundo yovuta ya laminating yopanda zosungunulira, PET/Al yosindikizidwa tsopano yathetsedwa ndi WD8262A/B yathu. Tinagwirizana ndi ogulitsa zida zingapo, tinayesa ndikuisintha kambirimbiri, ndipo pomaliza tinapanga WD8262A/B ndi magwiridwe antchito abwino. Mu chigawo cha Hunan, makasitomala athu ali ndi chidwi chachikulu pa ma laminates obwezerezedwa ndi Aluminium, ndipo ndizosavuta kuti ayesere. Pa substrate yosindikizidwa ya PET/AL/RCPP, zigawo zonse zimakutidwa ndi WD8262A/B. Pa PET/PA/AL/RCPP yosindikizidwa, zigawo za PET/PA ndi AL/RCPP zimagwiritsidwa ntchito WD8262A/B. Kulemera kwa chophimbacho ndi pafupifupi 1.8 - 2.5 g/m², ndipo liwiro lake ndi pafupifupi 100m/min - 120m/min.

Zipangizo zopanda zosungunulira za Kangda tsopano zapita patsogolo kwambiri pansi pa 128℃ ndipo zikupitilirabe kukhala zovuta pa 135℃ ngakhale 145℃ pochiza kutentha kwambiri. Kukana mankhwala kukufufuzidwanso.

KUYESA NTCHITO

Mavuto:

Vuto lalikulu popanga matumba obwezeretsera aluminiyamu okhala ndi zigawo zinayi ndikupeza kuphatikiza koyenera kwa zinthu zosiyanasiyana, kuphatikizapo mafilimu, zomatira, inki ndi zosungunulira. Makamaka, kupanga PET/AL yosindikizidwa mokwanira yakunja iyi ndiye kovuta kwambiri. Tinkakumana ndi milandu iyi, pomwe tinkatenga zinthu kuchokera kwa makasitomala kupita ku labotale yathu ndikuyesa zinthu zonse kuphatikiza zida, palibe cholakwika chomwe chidapezeka. Komabe, titaphatikiza zinthu zonse, magwiridwe antchito a laminate sanali okhutiritsa. Pokhapokha ngati ukadaulo wonse, zida, ndi zinthu zonse zili pansi pa ulamuliro, substrate ikhoza kupangidwa bwino. Mafakitale ena amatha kupanga substrate iyi sizitanthauza kuti wina aliyense angachite bwino.

2. Malo owongolera popanga

1) Kulemera kwa chophimba ndi pafupifupi 1.8 - 2.5 g/m2².

2) Chinyezi chozungulira

Chinyezi cha m'chipinda chimalangizidwa kuti chizilamulira pakati pa 40% - 70%. Madzi omwe ali mumlengalenga azitenga nawo mbali pa zomwe guluu amachita, chinyezi chambiri chimachepetsa kulemera kwa guluu ndikubweretsa zotsatira zina, zomwe zimakhudza magwiridwe antchito a kukana kubweza.

3) Zokonda pa laminator

Malinga ndi makina osiyanasiyana, malo oyenera monga kupsinjika, kupanikizika, ndi chosakanizira ayenera kuyesedwa kuti apeze momwe angagwiritsire ntchito bwino ndikupangitsa kuti laminate ikhale yosalala.

4) Zofunikira pa mafilimu

Kusalala bwino, mphamvu yoyenera ya dyne, kuchepa ndi chinyezi ndi zina zotero ndizofunikira kwambiri pakupanga laminating.

3. Zochitika zamtsogolo

Pakadali pano, kugwiritsa ntchito lamination yopanda zosungunulira kumachitika pa ma CD osinthika, omwe ali ndi mpikisano waukulu. Pa mfundo zaumwini, pali njira zitatu zopangira lamination yopanda zosungunulira.

Choyamba, chitsanzo chimodzi chokhala ndi ntchito zambiri. Chinthu chimodzi chingapange zinthu zambiri zopangidwa ndi wopanga ma CD osinthasintha, zomwe zingapulumutse nthawi yambiri, kumatira komanso kuwonjezera mphamvu.

Kachiwiri, magwiridwe antchito apamwamba, omwe amapereka kukana kwakukulu kwa kutentha ndi mankhwala.

Pomaliza, chitetezo cha chakudya. Tsopano lamination yopanda zosungunulira ili ndi zoopsa zambiri kuposa lamination yokhala ndi zosungunulira chifukwa ili ndi zoletsa zina pazinthu zogwira ntchito bwino monga matumba obweza a 135℃.

Koposa zonse, kupangira zinthu zopanda zosungunulira kukukula mofulumira, ukadaulo watsopano watuluka. M'tsogolomu, kupangira zinthu zopanda zosungunulira kungatenge gawo lalikulu pamsika wa ma CD osinthika ndi madera ena.
