Filimu yomatira ya Eva Hot Melt ya nsapato
Filimu yomatira yosungunuka ya EVA ndi yopanda fungo, yopanda kukoma komanso yopanda poizoni. Pali polima yosungunuka pang'ono yomwe ndi ethylene-vinyl acetate copolymer. Mtundu wake ndi wachikasu chopepuka kapena ufa woyera kapena granular. Chifukwa cha kristalo yochepa, kusinthasintha kwakukulu, komanso mawonekedwe ofanana ndi rabara, ili ndi makristalo okwanira a polyethylene olumikizirana, kotero ili ndi mawonekedwe a thermoplastic elastomer.
Utomoni wa EVA uli ndi kusinthasintha kofanana ndi mphira, komanso kusinthasintha kwabwino, kuwonekera bwino, kunyezimira komanso kutentha bwino. Sikuti kokha, umagwirizananso bwino ndi zinthu zina zophatikiza.
Ndi filimu yowonekera bwino yopangidwa ndi Ethylene Vinyl Acetate Copolymer yomwe ndi yoyenera kulumikiza nsalu, nsalu, nsapato, zojambula za aluminiyamu Mylar, PET, PP, zidutswa za thovu la EVA, chikopa, nsalu zosalukidwa, matabwa, mapepala, ndi zina zotero. Ilibe pepala lotulutsa lomwe limabweretsa mtengo wotsika kwambiri kuposa pepala lotulutsa. Kupatula apo, ndi chitsanzo chosungunuka pang'ono chomwe chimayenera kugwiritsidwa ntchito pazinthu zambiri zochepetsera kupsinjika. Chifukwa cha ntchito yake yabwino yopangira, imavomerezedwa kwambiri pakupanga nsapato pamwamba.
1. Kumverera kofewa m'manja: mukagwiritsa ntchito pa insole, mankhwalawa amakhala ofewa komanso omasuka kuvala.
2. Makulidwe akhoza kusinthidwa, tikhoza kuzindikira makulidwe ochepa kwambiri a 0.01mm.
3. Sichimayambitsa poizoni komanso chilengedwe: Sichidzatulutsa fungo loipa ndipo sichidzakhudza thanzi la ogwira ntchito.
4. Yosavuta kukonza pamakina komanso yopulumutsa ndalama zogwirira ntchito: Kukonza makina odzipangira okha, kumasunga ndalama zogwirira ntchito.
5. Malo osungunuka pakati: Izi zikugwirizana ndi kalembedwe ka nsalu zambiri.
Chophimba cha thovu cha EVA
Filimu yomatira yosungunuka imagwiritsidwa ntchito kwambiri pa insole lamination yomwe imalandiridwa ndi makasitomala chifukwa cha kufewa kwake komanso kuvala bwino. Kupatula apo, m'malo mwa glue yachikhalidwe, filimu yomatira yosungunuka yosungunuka yakhala ntchito yayikulu yomwe opanga nsapato masauzande ambiri akhala akugwiritsa ntchito kwa zaka zambiri.
Nsapato Zapamwamba Zofanana
Filimu yomatira yotentha ya L033A ingagwiritsidwenso ntchito pa nsapato zapamwamba chifukwa cha kufewa kwake komanso kuuma kwake komwe kungapangitse kuti kuwala kwa pamwamba kuwoneke kokongola.
Filimu yomatira yotentha ya L033A ingagwiritsidwenso ntchito pa mphasa yagalimoto, matumba ndi katundu, komanso pa lamination ya nsalu.
Ingagwiritsidwenso ntchito popangira nsapato zotchingira, zophimba nkhope zamasewera, masiketi, nsapato zamasewera, nsalu zovekera, zipangizo zomangira, ntchito zamanja, zinthu zoyendera alendo, zinthu zachipatala, zomangira mabuku, mipando, matabwa, zinthu zamkati mwa galimoto, katundu, zida zolondola, zipangizo zamagetsi, zida ndi zinthu zina zamagetsi.
