Madera Ogwiritsira Ntchito TPU

Mu 1958, Goodrich Chemical Company ku United States idalembetsa koyamba.Chogulitsa cha TPUKampani ya Estane. Kwa zaka 40 zapitazi, mitundu yoposa 20 ya zinthu yatuluka padziko lonse lapansi, iliyonse ili ndi mitundu ingapo ya zinthu. Pakadali pano, opanga zinthu zopangira za TPU padziko lonse lapansi ndi BASF, Covestro, Lubrizol, Huntsman, Macintosh, Gaoding, ndi zina zotero.
Monga elastomer yogwira ntchito bwino, TPU ili ndi malangizo osiyanasiyana azinthu zomwe zikugwiritsidwa ntchito ndipo imagwiritsidwa ntchito kwambiri pazinthu zofunika tsiku ndi tsiku, zinthu zamasewera, zoseweretsa, zinthu zokongoletsera, ndi zina. Nazi zitsanzo zingapo.
①Zipangizo za nsapato
TPU imagwiritsidwa ntchito makamaka popanga nsapato chifukwa cha kusinthasintha kwake komanso kusatha kuvala. Zovala za nsapato zokhala ndi TPU ndizosavuta kuvala kuposa nsapato wamba, kotero zimagwiritsidwa ntchito kwambiri popanga nsapato zapamwamba, makamaka nsapato zina zamasewera ndi nsapato wamba.
② Mapayipi
Chifukwa cha kufewa kwake, mphamvu yabwino yokoka, mphamvu yokoka, komanso kukana kutentha kwambiri, mapaipi a TPU amagwiritsidwa ntchito kwambiri ku China ngati mapaipi a gasi ndi mafuta pazida zamakanika monga ndege, matanki, magalimoto, njinga zamoto, ndi zida zamakina.
③ Chingwe
TPU imapereka mphamvu yolimbana ndi kung'ambika, kukana kugunda, komanso kupindika, ndipo kukana kutentha kwambiri ndi kochepa ndiye chinsinsi cha magwiridwe antchito a chingwe. Chifukwa chake pamsika waku China, zingwe zapamwamba monga zingwe zowongolera ndi zingwe zamagetsi zimagwiritsa ntchito TPU kuteteza zida zophikira za zingwe zopangidwa movuta, ndipo ntchito zawo zikuchulukirachulukira.
④ Zipangizo zachipatala
TPU ndi chinthu chotetezeka, chokhazikika, komanso chapamwamba kwambiri cholowa m'malo mwa PVC chomwe chilibe mankhwala owopsa monga ma phthalates, omwe amatha kusamutsidwa kupita ku magazi kapena zakumwa zina mkati mwa ma catheter azachipatala kapena matumba ndikuyambitsa zotsatirapo zoyipa. Ndi TPU yopangidwa mwapadera yotulutsa mpweya komanso yopangira jakisoni yomwe ingagwiritsidwe ntchito mosavuta ndi zosintha zazing'ono ku zida zomwe zilipo za PVC.
⑤ Magalimoto ndi njira zina zoyendera
Mwa kutulutsa ndi kuphimba mbali zonse ziwiri za nsalu ya nayiloni ndi polyurethane thermoplastic elastomer, ma rafts otha kupukutidwa ndi mphepo ndi ma rafts ofufuza omwe amanyamula anthu 3-15 akhoza kupangidwa, ndipo magwiridwe antchito awo ndi apamwamba kwambiri kuposa a rafts otha kupukutidwa ndi mphira; Ma elastomer a polyurethane thermoplastic olimbikitsidwa ndi fiberglass angagwiritsidwe ntchito kupanga ziwalo za thupi monga ziwalo zoumbidwa mbali zonse ziwiri za galimotoyo, zikopa za zitseko, ma bumpers, ma strips oletsa kupsinjika, ndi ma grilles.
