Ubulukhuni beI-TPU (i-thermoplastic polyurethane elastomer)ingenye yezakhiwo zayo ezibalulekile zomzimba, ezinquma ikhono lempahla lokumelana nokuguquguquka, ukuklwebheka, nokuklwebheka.Ukuqina kuvame ukukalwa kusetshenziswa i-Shore hardness tester, ehlukaniswe yaba izinhlobo ezimbili ezihlukene: Shore A kanye noShore D, esetshenziselwa ukukala.Izinto ze-TPUngobubanzi obuhlukene bobulukhuni.
Ngokwemiphumela yosesho, ububanzi bobulukhuni be-TPU bungasukela ku-Shore 60A ukuya ku-Shore 80D, okuvumela i-TPU ukuthi idlule ububanzi berabha nepulasitiki futhi igcine ukunwebeka okuphezulu kulo lonke uhla lobunzima.Ukulungiswa kokuqina kungafinyelelwa ngokushintsha ingxenye yezingxenye ezithambile neziqinile kuketango lamangqamuzana e-TPU.Ukushintsha kokuqina kungathinta ezinye izakhiwo ze-TPU, njengokwandisa ubulukhuni be-TPU okuholela ekwandeni kwe-tensile modulus namandla okudabula, ukwanda kokuqina nokucindezela okucindezelayo, ukwehla kobude, ukwanda kokuqina kanye nokukhiqizwa kokushisa okunamandla. , kanye nokwenyuka kokumelana nemvelo.
Kuzicelo ezingokoqobo, i-Ukukhethwa kokuqina kwe-TPUizonqunywa ngokusekelwe ezidingweni ezithile zohlelo lokusebenza.Isibonelo, i-TPU ethambile (ekalwa i-Shore A tester yobulukhuni) ifanele imikhiqizo edinga ukuthinta okuthambile nokwelulwa okuphezulu, kuyilapho i-TPU eqinile (ekalwa umhloli wokuqina we-Shore D) ifanele imikhiqizo edinga umthamo ophezulu wokuthwala futhi omuhle. ukumelana nokugqoka.
Ukwengeza, abakhiqizi abahlukene bangase babe namazinga athile okuqina kanye nokucaciswa komkhiqizo, okuvamise ukuchazwa kumanuwali obuchwepheshe bomkhiqizo.Ukuze uthole imininingwane, sicela ubheke iwebhusayithi esemthethweni ye-I-Yantai Linghua New Materials Co., Ltd.
Lapho ukhetha izinto ze-TPU, ngaphezu kokuqina, ezinye izinto ezibonakalayo, izindlela zokucubungula, ukuguquguquka kwemvelo, kanye nezici zezindleko zidinga ukucatshangelwa ukuze kuqinisekiswe ukuthi izinto ezikhethiwe zingahlangabezana nezidingo zokusebenza zezinhlelo zokusebenza ezithile.
