Thermoplastic polyurethane (TPU)ndi zinthu zogwira ntchito kwambiri zomwe zimatha kusintha kusintha kwa nsalu kuchokera ku ulusi wolukidwa, nsalu zosalowa madzi, ndi nsalu zosalukidwa kukhala zikopa zopanga. Multi functional TPU imakhalanso yokhazikika, yogwira bwino, yolimba kwambiri, komanso mawonekedwe osiyanasiyana komanso kuuma.
Choyamba, zinthu zathu zamtundu wa TPU zimakhala ndi mphamvu zambiri, kulimba, komanso kukana kuvala, zomwe zikutanthauza kuti nsalu zitha kugwiritsidwanso ntchito popanda kupunduka. Kukana kwamafuta, kukana kwamankhwala, ndi kukana kwa UV kumapangitsanso TPU kukhala zinthu zachilengedwe zomwe mungasankhe pazogwiritsa ntchito panja.
Kuphatikiza apo, chifukwa cha biocompatibility, kupuma, komanso kuyamwa kwa chinyezi, ovala amakonda kusankha nsalu zopepuka za polyurethane (PU) zokhala zomasuka komanso zowuma.
Thanzi lazinthu litha kukulitsidwanso chifukwa TPU imatha kubwezeredwanso, ndizomwe zimakhala zofewa kwambiri mpaka zolimba kwambiri. Poyerekeza ndi njira zina, iyi ndi njira yokhazikika yazinthu imodzi. Ilinso ndi zotsimikizika za low volatile organic compound (VOC), zomwe zingachepetse mpweya woipa.
TPU ikhoza kusinthidwa kuti ikhale ndi zinthu zenizeni monga kutsekereza madzi kapena kukana mankhwala a mafakitale. Kunena zowona, nkhaniyi imatha kusinthidwa kudzera munjira zina zopangira, kuchokera pakuluka ulusi mpaka kuwumba, kutulutsa, ndi kusindikiza kwa 3D, potero kumathandizira kupanga ndi kupanga zovuta. Nawa mapulogalamu angapo omwe TPU imapambana.
Ntchito: Zochita zambiri, zogwira ntchito kwambiriMtengo wa TPU
TPU ikhoza kupangidwa mu ulusi umodzi kapena zigawo ziwiri za ulusi, ndipo njira zothetsera mankhwala zimagwiritsidwa ntchito pafupifupi nthawi zonse (96%). Kudaya kwa anhydrous kumatha kuchepetsa kukhudzidwa kwa chilengedwe ndi njira zopangira. Mosiyana ndi izi, akasungunula kupota, mayankho nthawi zambiri sagwiritsidwa ntchito, kotero mayankhowa amakhala ndi mpweya wochepa kapena wopanda VOC. Komanso, Sungunulani kupota ali makamaka zofewa khungu kumva.
Ntchito: TPU madzi nsalu nsalu, ntchito chimakwirira galimoto, matumba njinga, ndi kupanga zikopa
TPU yosalowa madzi komanso imalimbana ndi madontho. Kuphatikizidwa ndi nthawi yayitali ya moyo, ukadaulo wa TPU ndi chisankho chabwino pazogwiritsa ntchito zolemetsa monga nsalu zopanda madzi pamagalimoto, zikwama zanjinga, ndi zikopa zopanga. Phindu limodzi lofunika ndilakuti thermoplastic polyurethane ndiyosavuta kuyibwezeretsanso kuposa zida zambiri zomwe zilipo zopanda madzi.
Palibe mankhwala omwe amagwiritsidwa ntchito mu thermoplastic process monga rolling kapena T-die extrusion kuwonetsetsa kuchepetsedwa kapena kuthetsedwa kwathunthu kwa VOC. Panthawi imodzimodziyo, palibe chifukwa chodyera madzi kuti muchotse mankhwala owonjezera, omwe ndi gawo lachidziwitso chamankhwala.
Ntchito: Chikopa chokhazikika komanso chosinthika cha TPU
Maonekedwe ndi maonekedwe a chikopa chopangidwa ndizovuta kusiyanitsa ndi chikopa chachilengedwe, ndipo nthawi yomweyo, mankhwalawa ali ndi zosankha zopanda malire za mtundu ndi mawonekedwe a pamwamba, komanso kukana kwachilengedwe kwa TPU mafuta, kukana mafuta, ndi kukana kuvala. Chifukwa chakusowa kwa zida zilizonse zochokera ku nyama, zikopa za TPU ndizoyeneranso kwa omwe amadya masamba. Pamapeto pa gawo logwiritsira ntchito, zikopa zopangidwa ndi PU zimatha kusinthidwanso mwamakani.
Ntchito: Nsalu yosalukidwa
Malo ogulitsa apadera a TPU osalukidwa nsalu ndi kukhudza kwake bwino komanso kofewa, komanso kutha kupindika mobwerezabwereza, kutambasula, ndi kusinthasintha pa kutentha kwakukulu popanda kusweka.
Ndizoyenera makamaka pamasewera ndi zovala zovala wamba, pomwe ulusi wotanuka umatha kuphatikizidwa munjira yopumira kwambiri, zomwe zimapangitsa kuti mpweya ulowe mosavuta komanso kutuluka thukuta.
Kukumbukira kwa mawonekedwe kumatha kupangidwanso kukhala nsalu ya TPU ya polyester yosalukidwa, yomwe malo ake osungunuka amatanthauza kuti imatha kukanikizidwa pansalu zina. Zida zosiyanasiyana zobwezerezedwanso, zozikidwa pang'ono, komanso zosapunduka zitha kugwiritsidwa ntchito ngati nsalu zosalukidwa.
