Ubulukhuni beI-TPU (Thermoplastic Polyurethane Elastomer)kungenye yezinto zayo ezibalulekile ezibonakalayo, ezinquma ikhono lokwesisekelo lokumelana nokulimazeka, ukuklwebheka kanye nokuklwebheka. Ubulukhuni buvame ukukalwa kusetshenziswa umhloli wobulukhuni basogwini, oluhlukaniswe izinhlobo ezimbili ezahlukene: ogwini a noShore D, esetshenziselwa ukukalaIzinto ze-TPUNgamabanga ahlukile abulukhuni.
Ngokusho kwemiphumela yokucinga, ububanzi be-hardness of TPU bungasuka esogwini 60, oluvumela i-TPU ukuthi ibeke ubulukhuni ubulukhuni benjoloba nepulasitiki futhi bugcine ukuqina okuphezulu kulo lonke uhla lwepulasitiki kulo lonke uhla lonke lobulukhuni. Ukulungiswa kobulukhuni kungatholwa ngokushintsha ingxenye yezingxenye ezithambile nezinzima ku-TPU Moleculat chain. Ushintsho lobulukhuni lungathinta ezinye izakhiwo ze-TPU, njengokukhulisa ubulukhuni be-TPU okuholela ekwandeni kwe-modulus tensile kanye nezinyembezi, ukwehla kokuqina, nokwanda kokuvinjelwa kwemvelo.
Kuhlelo lokusebenza olusebenzayo,Ukukhetha kanzima kwe-TPUizonqunywa ngokusekelwe kwizidingo ezithile zohlelo lokusebenza. Isibonelo, i-TPU ethambile (elinganiswe nguShore i-Harveness Tenter) ilungele imikhiqizo edinga ukuthinta okuthambile kanye nokugcwala okuphezulu, ngenkathi kunzima i-TPU (kulinganiswe kanzima
Ngaphezu kwalokho, abakhiqizi abahlukene bangaba namazinga athile obulukhuni kanye nokucaciswa komkhiqizo, okuvame ukucaciswa okuningiliziwe kumabhukwana obuchwepheshe womkhiqizo. Ngemininingwane, sicela ubheke kuwebhusayithi esemthethweni yeI-Yantai Linghua Materials Co, LTD.
Lapho ukhetha izinto ze-TPU, ngaphezu kobulukhuni, ezinye izakhiwo ezibonakalayo, izindlela zokucubungula, ukuzivumelanisa nezimo zemvelo, nezindleko zezindleko kudingeka kubhekwe ukuze kuqinisekiswe ukuthi izinto ezikhethiwe zingahlangabezana nezidingo zokusebenza kwezicelo ezithile.
