1. Kodi n'chiyaniFilimu Yomatira Yotentha ya EVA?
Ndi chinthu cholimba, chomatira cha thermoplastic chomwe chimaperekedwa mu filimu yopyapyala kapena mawonekedwe a ukonde.
Polima yake yoyambira ndiEthylene Vinyl Acetate (EVA)copolymer, yomwe nthawi zambiri imaphatikizidwa ndi ma resins omata, sera, zokhazikika, ndi zina zosinthira.
Imayatsidwa ndi kutentha ndi kupanikizika, ndikusungunuka kuti ipange chomangira champhamvu ikazizira.
2. Katundu Wofunika:
Thermoplastic:Zimasungunuka zikatenthedwa ndipo zimauma zikazizira.
Yopanda zosungunulira komanso Yoteteza chilengedwe:Mulibe mankhwala osungunuka achilengedwe (VOCs), zomwe zimapangitsa kuti ikhale yoyera komanso yotetezeka kuposa zomatira zopangidwa ndi zosungunulira.
Kugwirizana Mwachangu:Kugwira ntchito ndi kugwirizana kumachitika mwachangu kutentha ndi kupanikizika zikagwiritsidwa ntchito.
Chiyambi Chabwino Choyambira:Imapereka mphamvu yogwira koyambirira ikasungunuka.
Kusinthasintha:Makanema opangidwa ndi EVA nthawi zambiri amakhala osinthasintha bwino akamalumikizana, ndipo amafanana bwino ndi zinthu zomwe zili mkati.
Kuphatikana Kwambiri:Imalumikizana bwino ndi zinthu zosiyanasiyana zokhala ndi mabowo ndi zopanda mabowo (nsalu, thovu, pulasitiki, matabwa, zitsulo).
Kukonza Kosavuta:Yogwirizana ndi zida zokhazikika zamakampani zopaka utoto ndi zomangira.
Yotsika Mtengo:Kawirikawiri njira yomatira yotsika mtengo poyerekeza ndi mitundu ina ya HMAM (monga PA, TPU).
3. Ntchito Zoyambira:
Nsalu ndi Zovala:
Nsalu zopaka utoto (monga zomangira ma kolala, ma cuffs, ndi malamba a m'chiuno).
Kutseka m'mphepete ndi msoko.
Kulumikiza appliqués, zigamba, ndi zilembo.
Kulumikiza nsalu zosalukidwa (monga mu zinthu zaukhondo, zosefera).
Zinthu zomangira nsapato monga toe puffs, counters, insoles, ndi linings.
Kumangirira pamwamba pa midsoles kapena outsoles (nthawi zambiri kuphatikiza ndi zomatira zina).
Zikopa zopangidwa ndi nsalu zopangidwa ndi laminating.
Kupaka:
Kupaka kwapadera kwa lamination (monga pepala/foil, pepala/pulasitiki).
Kutseka makatoni ndi mabokosi.
Kupanga mabokosi olimba.
Magalimoto ndi Mayendedwe:
Zinthu zomangira mkati mwa nyumba (ma headliners, ma panels a zitseko, makapeti, ma trunk liners).
Nsalu zopaka utoto kuchokera ku thovu kapena zinthu zophatikizika.
Kumanga ndi kutseka m'mphepete.
Mipando ndi Zovala Zapamwamba:
Nsalu yomangirira ku thovu.
Kutseka m'mphepete ndi kuphimba m'mabedi ndi ma cushion.
Malo okongoletsera okhala ndi lamination.
Nsalu Zaukadaulo & Ma Laminate Amafakitale:
Magawo omangirira mu zosefera.
Ma geotextiles opaka utoto.
Kupanga zinthu zopangidwa ndi zinthu zosiyanasiyana zogwiritsidwa ntchito m'mafakitale.
Zodzipangira ndi Zaluso:(Zosintha za malo otsika osungunuka)
Zipangizo zomangira mapulojekiti osangalatsa.
Zojambulajambula ndi zokongoletsera za nsalu.
4. KukonzaNjira:
5. Flatbed Lamination:Pogwiritsa ntchito makina osindikizira otentha a platen.
Kupaka Kosalekeza kwa Roll Lamination:Pogwiritsa ntchito ma rollers a kalendala otenthedwa kapena ma rollers a nip.
Kugwirizanitsa kwa Contour:Kugwiritsa ntchito zida zapadera zotenthetsera pa mawonekedwe enaake.
Kugwiritsa Ntchito Ma Ultrasonic:Kugwiritsa ntchito mphamvu ya ultrasonic kusungunula filimuyo m'deralo (yomwe si yofala kwambiri pa EVA kuposa mitundu ina).
Njira:Ikani filimu pakati pa zinthu zoyambira -> Ikani kutentha (kusungunula filimuyo) -> Ikani kupanikizika (kuonetsetsa kuti ikugwirizana ndi kunyowetsa) -> Kuziziritsa (kulimbitsa ndi kupanga mgwirizano).
6. Ubwino wa EVA HMAM:
Yoyera komanso yosavuta kugwiritsa ntchito (yopanda chisokonezo, yopanda fumbi).
Kukhuthala kokhazikika komanso kugawa komatira.
Palibe nthawi yofunikira yowumitsa/kukonza pambuyo pomangirira.
Kukhazikika bwino kwa malo osungiramo zinthu m'mikhalidwe yabwinobwino.
Kugwirizana bwino kwa kulimba, kusinthasintha, ndi mtengo.
Kutentha kotsika kwambiri poyerekeza ndi ma HMAM ena.
6. Zolepheretsa/Zoganizira:
Kuzindikira kutentha:Ma bond amatha kufewa kapena kulephera kutentha kwambiri (nthawi zambiri amakhala ochepa pa <~65-80°C / 150-175°F nthawi zonse, kutengera kapangidwe kake).
Kukana Mankhwala:Kawirikawiri kukana kwa zinthu zosungunulira, mafuta, ndi mankhwala amphamvu kumakhala kochepa.
Kuyenda pang'onopang'ono:Pakakhala katundu wosalekeza, makamaka kutentha kwambiri, ziwalo zomangiriridwa zimatha kukwawa (kuwonongeka pang'onopang'ono).
Kukana chinyezi:Magwiridwe antchito amatha kusiyanasiyana kutengera kapangidwe kake; sikuti kwenikweni ndi madzi monga mafilimu ena a PUR.
Kugwirizana kwa Substrate:Ngakhale kuti ndi yotakata, kumamatira ku mapulasitiki otsika mphamvu kwambiri (monga PP, PE) nthawi zambiri kumafuna kukonza pamwamba kapena kupanga zinthu zinazake.
