Thermoplastic polyurethane (TPU) ndi gulu lapadera la pulasitiki lopangidwa pamene polyaddition reaction imachitika pakati pa diisocyanate ndi diol imodzi kapena zingapo. Koyamba kupangidwa mu 1937, polima yosunthika iyi ndi yofewa komanso yosinthika ikatenthedwa, yolimba ikazizira ndipo imatha kukonzedwanso kangapo popanda kutaya kukhulupirika kwake. Amagwiritsidwa ntchito ngati pulasitiki yauinjiniya wosasunthika kapena m'malo mwa mphira wolimba, TPU imadziwika ndi zinthu zambiri kuphatikiza: kutalika kwakukulu ndi kulimba kwamphamvu; elasticity yake; ndi mosiyanasiyana, kuthekera kwake kukana mafuta, mafuta, zosungunulira, mankhwala ndi abrasion. Makhalidwe awa amapangitsa TPU kukhala yotchuka kwambiri m'misika yambiri ndikugwiritsa ntchito. Imasinthasintha mwachilengedwe, imatha kutulutsidwa kapena jekeseni pazida wamba zopangira thermoplastic kuti ipange zida zolimba zomwe zimakhala ndi nsapato, chingwe & waya, payipi ndi chubu, filimu ndi pepala kapena zinthu zina zamakampani. Itha kuphatikizidwanso kuti ipange zomangira zolimba za pulasitiki kapena kukonzedwa pogwiritsa ntchito zosungunulira za organic kuti zipange nsalu zokhala ndi laminated, zokutira zoteteza kapena zomatira.
Kodi nsalu ya Waterproof TPU ndi chiyani?
Nsalu ya TPU yopanda madzi ndi nembanemba yosanjikiza ndi TPU yokonza zinthu zambiri.
Phatikizani mphamvu yong'ambika kwambiri, yosalowa madzi, komanso kufalitsa chinyezi chochepa. Zapangidwira njira yopangira nsalu. Wodziwika chifukwa cha kusasinthika kwake, amatulutsa mawonekedwe apamwamba kwambiri, odalirika kwambiri a thermoplastic polyurethane (TPU) ndi mafilimu opumira amadzi a copolyester omwe amapuma pantchito. Makanema osunthika komanso okhazikika a TPU - ndi mapepala ndi mapepala amagwiritsidwa ntchito polumikizira nsalu, kutsekereza madzi, komanso kugwiritsa ntchito mpweya kapena madzi. Makanema owonda kwambiri komanso a hydrophilic TPU ndi mapepala ndi oyenera kuyika nsalu. Okonza amatha kupanga zopangira zopangira nsalu zokhala ndi madzi zopumira m'madzi mufilimu imodzi - mpaka - nsalu zopangira nsalu. Nkhaniyi imapereka mpweya wabwino wogwiritsa ntchito chitonthozo. Mafilimu oteteza nsalu ndi pepala amawonjezera kuphulika, kuphulika, ndi kukana mankhwala ku nsalu zomwe zimamangiriridwa.
