Filimu ya EVA ndi mtundu wa filimu yokhuthala kwambiri yopangidwa ndi polymer resin (ethylene-vinyl acetate copolymer) ngati chinthu chachikulu chopangira, kuwonjezera zowonjezera zapadera ndi kukonza pogwiritsa ntchito zipangizo zapadera. Ndi kafukufuku wopitilira ndi chitukuko cha filimu ya EVA, filimu ya EVA ikupitirira kukula, ndipo filimu ya EVA yakunyumba yakhala yotumizidwa kunja kuchokera kunja.
Anthu ambiri amaganiza kuti filimu ya EVA ingagwiritsidwe ntchito pokongoletsa mkati kokha, koma kuyambira mu 2007, Shandong Fangding Safety Glass Technology Co., Ltd (yomwe idakhazikitsidwa ndi Fangding Technology Co., Ltd.), yapempha bwino satifiketi ya CCC, yomwe ikuwonetsa kuti filimu ya EVA ikukwaniritsa zofunikira za dziko lonse pagalasi la uinjiniya wakunja pankhani ya mphamvu, kuwonekera bwino kapena kumatirira. Kuyambira pamenepo, zathetsa mkangano wakuti PVB ndiye yokhayo youma yomwe imagwiritsidwa ntchito mu uinjiniya wakunja ku China.
Filimu ya EVA mu ntchito zaukadaulo wakunja:
★ Mu Marichi 2009, dzikolo linayamba kupanga, mu Marichi 2010, kutulutsidwa kovomerezeka kwa muyezo wa dziko lonse wa galasi lopangidwa ndi laminated kumati filimu ya PVB iyenera kugwiritsidwa ntchito pagalasi yamagalimoto. Ndipo magalasi opangidwa ndi laminated, monga khonde loteteza, denga la magetsi, mawindo a bizinesi, khoma la nsalu yagalasi, filimu ya PVB ndi EVA zingagwiritsidwe ntchito.
Kukana kuwala kwa EVA, kusadziwa madzi, kukana nyengo, kukana dzimbiri, komanso kukana phokoso kuli bwino kuposa PVB, kuphatikiza kusungira kosavuta, ukadaulo wosavuta wokonza, kugwiritsa ntchito kosavuta, komanso mtengo wotsika, makampani ambiri amakonda kwambiri EVA.
Aliyense mumakampani amadziwa kuti autoclave ikapangidwa ndi galasi lopindika, ndikofunikira kugwiritsa ntchito matumba a silicone popangira vacuum, ndipo makampani ena kuti asunge ndalama, kupangira vacuum ndi matumba apulasitiki otayidwa, kenako nkulowa mu autoclave, zomwe zimakhala zovuta kwambiri ndipo mtengo wake ndi wokwera.
Koma ng'anjo ya EVA lamination imathetsa vutoli: galasi lopindika la laminated likhoza kuyikidwa mu ng'anjo kuti liyambe kupanikizika, kenako nkulowa mu autoclave. Tsopano, ndi chitukuko cha ukadaulo, Fangding Technology Co., Ltd. yapanga zida zamagalasi zopindika zomwe zimatha kupangidwa kamodzi, zomwe zimapulumutsa nthawi ndi ndalama zambiri.
Kugwiritsa ntchito filimu ya EVA pagalasi lokongoletsera:
Magalasi ojambula monga waya, nsalu, mapepala ojambulira zithunzi, ndi cholimbitsa chimodzi chiyenera kupangidwa ndi filimu ya EVA, makamaka galasi latsopano la ojambula lomwe lili ndi zinthu zenizeni pakati, monga maluwa enieni ndi udzu wa bango. Tsopano mtundu wa magalasi ojambula apamwamba kwambiri amatumizidwa kunja.
Kugwiritsa ntchito filimu ya EVA pagalasi latsopano la mphamvu:
Kugwiritsa ntchito filimu ya EVA mu mphamvu zatsopano kumaonekera makamaka m'mapanelo a solar photovoltaic, magalasi oyendetsera magetsi, magalasi ochepetsera kuwala ndi zina zotero. Kupanga mapanelo a solar photovoltaic kumapangidwa ndi silicon wafer ndi bolodi lozungulira ndi filimu ya EVA composite, nthawi zambiri yopangidwa ndi makina oyeretsera magetsi; Magalasi oyendetsera magetsi achizolowezi amatha kupangidwa kuti aziyendetsa magetsi poika filimu yoyendetsera magetsi (ITO film) pamwamba pa galasi wamba. Tsopano galasi loyendetsera magetsi ndi galasi lopangidwa ndi filimu ya EVA ndi filimu yoyendetsera magetsi, ndipo magalasi ena amapangidwanso ndi LED, yomwe ndi yokongola komanso yopatsa.
Galasi losinthika ndi mtundu watsopano wa chinthu chapadera chagalasi la photoelectric chomwe chimaphatikiza filimu yamadzimadzi ya kristalo ndi filimu ya EVA pakati pa zigawo ziwiri zagalasi, kenako ndikupanga kapangidwe ka intercalation pambuyo pa kutentha ndi kupanikizika kwina. Tsopano galasi latsopano lamphamvu lopangidwa ndi filimu ya EVA lakhala likugwiritsidwa ntchito kwambiri m'mabizinesi komanso m'malo opezeka anthu ambiri komanso m'nyumba za mabanja.
Chothandizira cha filimu ya EVA pa galasi la mafakitale:
Galasi la chitseko cha firiji ndi makina ochapira omwe alipo panopa ndi magalasi otenthetsera ndipo zipangizo zapadera pafupifupi 3.2mm zokhala ndi filimu ya EVA zimapakidwa pamodzi kutentha kwambiri, komwe ndi kokongola komanso kotetezeka.
Pofuna kukwaniritsa zosowa za makasitomala ambiri, kafukufuku ndi chitukuko cha mafilimu a EVA zikuwonjezekanso, ndikukhulupirira kuti posachedwa, mafilimu a EVA adzakhalanso ndi zatsopano mu magalimoto, ndege, ndi magalasi a m'madzi.
