Thermoplastic polyurethane (TPU) yog ib pawg yas tshwj xeeb uas tsim los thaum muaj kev sib xyaw ua ke ntawm diisocyanate thiab ib lossis ntau diols. Thawj zaug tsim tawm xyoo 1937, cov polymer no mos thiab ua tau thaum sov, tawv thaum txias thiab muaj peev xwm rov ua dua ntau zaus yam tsis poob qhov kev ua tiav ntawm cov qauv. Siv ua cov yas engineering malleable lossis hloov cov roj hmab tawv, TPU muaj npe nrov rau ntau yam suav nrog nws: lub zog ntev thiab lub zog tensile; nws qhov elasticity; thiab rau ntau qib, nws lub peev xwm los tiv taus roj, roj, cov kuab tshuaj, tshuaj lom neeg thiab kev puas tsuaj. Cov yam ntxwv no ua rau TPU nrov heev thoob plaws ntau yam kev lag luam thiab daim ntawv thov. Nws muaj kev ywj pheej, nws tuaj yeem raug extruded lossis txhaj tshuaj molded ntawm cov khoom siv thermoplastic tsim khoom siv los tsim cov khoom khov kho feem ntau rau khau, cable & hlau, hose thiab raj, zaj duab xis thiab ntawv lossis lwm yam khoom lag luam. Nws kuj tseem tuaj yeem sib xyaw ua ke los tsim cov yas moldings ruaj khov lossis ua tiav siv cov kuab tshuaj organic los tsim cov ntaub laminated, cov txheej tiv thaiv lossis cov nplaum ua haujlwm.
Cov ntaub TPU tsis muaj dej yog dab tsi?
Cov ntaub TPU tsis muaj dej yog ib txheej ob txheej uas muaj cov yam ntxwv ua haujlwm ntau yam ntawm TPU.
Muaj lub zog tsim kua muag siab, tiv dej tsis nkag, thiab tsis muaj dej nkag. Tsim los rau cov txheej txheem lamination ntaub. Paub txog nws qhov sib xws, extrudes cov zoo tshaj plaws, feem ntau txhim khu kev qha thermoplastic polyurethane (TPU) thiab copolyester waterproof breathable zaj duab xis hauv kev lag luam. Cov ntau yam thiab ruaj khov TPU - raws li zaj duab xis thiab daim ntawv yog siv rau kev sib txuas ntaub, tiv dej tsis nkag, thiab huab cua lossis kua daim ntawv thov. Cov zaj duab xis TPU super nyias thiab hydrophilic thiab daim ntawv yog qhov zoo tshaj plaws rau lamination rau cov ntaub. Cov neeg tsim qauv tuaj yeem tsim cov khoom siv textile uas tsis muaj dej tsis nkag uas pheej yig hauv ib zaj duab xis - rau - ntaub lamination. Cov khoom siv muab kev ua pa zoo rau tus neeg siv kev nplij siab. Cov zaj duab xis textile tiv thaiv thiab daim ntawv ntxiv qhov tho, kev sib txhuam, thiab kev tiv thaiv tshuaj rau cov ntaub uas lawv tau sib txuas.
