Thermoplastic polyirethane (tpu) ndi gulu lapadera la pulasitiki lomwe limapangidwa ngati ma polthadation chimachitika pakati pa diisoctate ndi imodzi kapena zingapo. Choyamba Kupangidwa mu 1937, polima wosinthasintha ndi wofewa komanso wopatsa mphamvu akamatenthedwa, movutikira atakhazikika kangapo popanda kutaya umphumphu. Amagwiritsidwa ntchito ngati pulasitiki yothandizira kapena ngati yolowa mu mphira wolimba, TPU imadziwika kuti kuphatikiza zinthu zambiri kuphatikiza: Mphamvu yayitali komanso yotalika; zolemetsa zake; Ndipo poyerekeza madigiri, kuthekera kwake pokana mafuta, mafuta, ma sol sol, mankhwala ndi abrasion. Makhalidwe awa amapanga TPU yotchuka kwambiri m'misika ndi ntchito. Kuthana ndi kuthekera, kumatha kuwonongeka kapena jakisoni wopangidwa pa zida zopangidwa ndi thermoplastic kuti apange zinthu zolimba, chinsinsi & chubu, makanema kapena mafilimu ena. Itha kuphatikizidwanso kuti ipange nkhuni zolimba za pulasitiki kapena kukonzedwa pogwiritsa ntchito ma solfordic okhazikika kuti apange zikwangwani, zoteteza kapena zomata zolimbitsa kapena zomata.
Kodi nsalu ya madzi TPU ndi iti?
Nsalu yam'madzi TPU ili ndi bi - membrane ndi TPU yopanga zigawo zambiri.
Phatikizanipo mulingo wambiri wamisozi, madzi osayamwa, komanso kufalikira kochepa. Adapangidwira kuti agwirizanitse ntchito. Wodziwika chifukwa cha kusasinthika kwake, kumabweza mtengo wapamwamba kwambiri, poureretharisne (TPU) ndi Coprolyester Wopanda Waterproof Worts. Mafayilo osintha ndi olimba TPU - makanema ophatikizidwa ndi pepala amagwiritsidwa ntchito ngati nsalu yolumikizira, kuthilira madzi, ndi mpweya kapena malo amtundu wamadzimadzi. Mafilimu owonda kwambiri ndi hydrophilic tpu ndi pepala ndi pepala loyenererana loyamwa. Opanga amatha kupanga mtengo - ogwira ntchito molimbika am'madzi opanga ma corposile mufilimu imodzi - mpaka - nsalu yomanga. Zinthuzi zimapereka nthawi zabwino kwambiri kwa ogwiritsa ntchito. Mafilimu oteteza ndi pepala lonjezerani punction, Abrasion, ndi kukana mankhwala ku nsalu zomwe zimangidwa.
