Zakudya Packaging Mpukutu Filimu Yowongoka Makina Odzaza Makina Opangira Mapulasitiki Kanema

Filimu yamagulu opangidwa kuchokera ku zigawo ziwiri kapena kuposerapo iyenera kukhala yosasiyanitsidwa ngati filimu imodzi.Izi zikuphatikizapo zambiri osati zomatira pakati pa mafilimu awiriwa.Komanso zokhudzana ndi filimu ya inki.Zomatira ndi zinthu zopangidwa Zomatira zambiri zimakhala zomatira za polyurethane (PU) zamagulu awiri.The mankhwala anachita pobowola ndondomeko amachiza zomatira.Zomatira pamwamba pa gawo lapansi ndizochita zakuthupi ndipo gawo laling'ono chabe ndi njira yamankhwala.Panthawiyi, zigawo za zomatirazo zimakumbidwa pamodzi ndi zigawo za filimu ya pulasitiki ndikuchiritsidwa.
Ngati filimu yophatikizika yasindikizidwa kale panthawi yolumikizana ndiye kuti zomatira ndi inki ziyenera kukwaniritsa zofunikira zambiri.Chofunikira kwambiri ndi chakuti wosanjikiza wamkati uyenera kukhala wokhazikika bwino komanso wowuma musanayambe lamination.Izi zikutanthauza kuti palibe zotsalira zosungunulira zomwe zimaloledwa mu liner yosindikizidwa.Koma zosungunulira kapena mowa kaŵirikaŵiri zimasiyidwa mu chomangira cha inki.Pachifukwa ichi, katundu wa zomatira ayenera kumangirira ku ma radicals aulere (-OH magulu).Kupanda kutero, zomatira ndi wothandizira amachiritsa okha ndi kutaya katundu wawo woyambirira.
Pakati pa zomatira, zomatira zosungunulira zimasiyanitsidwa ndi zomatira zopanda zosungunulira monga zomatira za UV.Kubowola kopangidwa ndi zosungunulira kumafuna njira yowumitsa kuti isungunuke.Zomatira za UV zikagwiritsidwa ntchito, kuwala kwa UV kumayenda kudutsa filimu yophatikizika kupita ku zomatira kuti apange polymerize zomatirazo pamodzi.
1. Pawiri youma
Zimatanthawuza njira yomwe zomatirazo zimaphatikizidwa mu mkhalidwe wouma.Choyamba, zomatirazo zimakutidwa pa gawo lapansi.Pambuyo kuyanika mumsewu wowumitsa, zosungunulira zonse mu zomatira zimauma.Njira yosungunula zomatira, kumangiriza gawo lina kwa iyo, kuziziritsa, ndi kuchiritsa kuti apange zinthu zophatikizika zomwe zili ndi zinthu zabwino.
2. Extrusion pawiri
Amadziwikanso kuti kuponyera kompositi, yomwe ndi imodzi mwazinthu zazikulu zopangira ma CD osinthika.Amasungunula ma thermoplastics monga polyethylene ndi polypropylene mu makina opangira zowonjezera, ndipo amatuluka mofanana mu filimu yopyapyala kuchokera kumutu wathyathyathya, ndipo amakutidwa mosalekeza Pazinthu zapansi, filimu yophatikizika ya zigawo ziwiri kapena kuposerapo imapangidwa mwa kukanikiza ndi chopukusira kuthamanga ndi kuziziritsa ndi chodzigudubuza ozizira.
Extrusion lamination ali ndi ubwino wa kusala kudya liwiro, ndondomeko yosavuta kupanga, woyera kupanga chilengedwe, mkulu kupanga dzuwa, ntchito yosavuta, mtengo wotsika, ndipo palibe zotsalira zosungunulira.malo ofunika.
