Paerewa Pakari mō ngā elastomers polyurethane thermoplastic TPU

Te pakari oTPU (erastomer polyurethane thermoplastic)ko tētahi o ōna āhuatanga ā-tinana nui, e whakatau ana i te kaha o te rauemi ki te ātete i te whakarerekētanga, ngā karawarawa, me ngā rakuraku. Ko te tikanga ka inehia te pakeketanga mā te whakamahi i tētahi taputapu whakamātautau pakeketanga o te takutai moana, e wehea ana ki ngā momo e rua: te takutai moana A me te takutai moana D, e whakamahia ana hei ineNgā rauemi TPUme ngā awhe pakeke rerekē.

E ai ki ngā hua rapu, ka taea e te awhe pakeke o te TPU te horapa mai i Shore 60A ki Shore 80D, e āhei ai te TPU ki te hora i te awhe pakeke o te rapa me te kirihou, me te pupuri i te ngāwari teitei puta noa i te awhe pakeke katoa. Ka taea te whakatutuki i te whakatikatika o te pakeke mā te whakarerekē i te ōwehenga o ngā wāhanga ngohengohe me ngā wāhanga pakeke i roto i te mekameka ngota TPU. Ka taea e te huringa o te pakeke te pā ki ētahi atu āhuatanga o te TPU, pērā i te whakanui ake i te pakeke o te TPU, ka piki ake te modulus tensile me te kaha haehae, ka piki ake te pakari me te ahotea pēhi, ka heke te roa, ka piki ake te mātotoru me te whakaputa wera hihiri, me te piki ake o te ātete taiao.

I roto i ngā tono mahi, ko tekōwhiringa mārō o te TPUka whakatauhia i runga i ngā whakaritenga tono motuhake. Hei tauira, he pai te TPU ngawari (e inehia ana e te whakamātautau pakeke o Shore A) mō ngā hua e hiahia ana ki te pā ngawari me te roa teitei, ko te TPU mārō (e inehia ana e te whakamātautau pakeke o Shore D) he pai mō ngā hua e hiahia ana ki te kaha kawe kawenga teitei me te ātete pai ki te kakahu.

Hei tāpiritanga, tera pea he paerewa pakeke me ngā whakaritenga hua motuhake a ngā kaihanga rerekē, e whakaaturia ana i roto i ngā pukapuka hangarau hua. Mō ētahi atu kōrero, tirohia te paetukutuku mana oYantai Linghua New Materials Co., Ltd.

I te wā e whiriwhiri ana i ngā rauemi TPU, me whai whakaaro anō hoki ki ētahi atu āhuatanga ā-tinana, ngā tikanga tukatuka, te urutau ki te taiao, me ngā āhuatanga utu kia taea ai e ngā rauemi kua tīpakohia te whakatutuki i ngā whakaritenga mahi o ngā tono motuhake.
