Te Resin Polyurethane Thermoplastic (TPU) mō ngā Kete Waea Pūkoro, Ngā Kiriata TPU Mārama Teitei, Kaihanga Paura TPU

Ko te TPU, he whakarāpopototanga mō te Thermoplastic Polyurethane, he elastomer thermoplastic whakamiharo me te whānuitanga o ngā āhuatanga tino pai me te whānuitanga o ngā tono.

He poraka copolymer te TPU i hangaia mā te tauhohenga o ngā diisocyanates me ngā polyols. Kei roto ko ngā wāhanga mārō me ngā wāhanga ngohengohe e taupatupatu ana. Ka whakarato ngā wāhanga mārō i te pakari me te mahi ā-tinana, ko ngā wāhanga ngohengohe ia ka whakarato i te ngāwari me ngā āhuatanga elastomeric.

Ngā Āhuatanga

• Ngā Āhuatanga Mīhini5: He kaha nui te TPU, me te kaha kume o te 30 - 65 MPa, ā, ka taea te tu atu i ngā whakarerekētanga nui, me te roa o te pakaru tae atu ki te 1000%. He tino pai hoki tōna ātete ki te pakū, e rima ngā wā he nui ake te ātete ki te kakahu i te rapa maori, ā, he nui te ātete ki te haehae me te ātete ki te piko, he mea tino pai mō ngā tono e hiahia ana ki te kaha miihini teitei.

• Ātete Matū5: He tino ātete te TPU ki ngā hinu, ki ngā hinu whakahinuhinu, me ngā momo whakarewa maha. He pai te pumau i roto i ngā hinu wahie me ngā hinu miihini. Hei tāpiri, he pai te ātete ki ngā matū noa, e roa ake ai te ora o ngā hua i roto i ngā taiao pa-matū.

• Ngā Āhuatanga WeraKa taea e te TPU te mahi pai i roto i te awhe pāmahana mai i te -40 °C ki te 120 °C. Ka mau tonu te ngāwari me ngā āhuatanga miihini i ngā pāmahana iti, ā, kāore e ngāwari te huri, te rewa rānei i ngā pāmahana tiketike.

• Ngā Āhuatanga Kē Atu4: Ka taea te hanga i te TPU hei whakatutuki i ngā taumata mārama rerekē. He tino mārama ētahi rauemi TPU, ā, i te wa ano, he pai tonu te ātete ki te pakū. He pai hoki te manawa o ētahi momo TPU, me te tere tuku kohu ka taea te whakarerekē kia rite ki ngā whakaritenga. Hei tāpiri, he tino pai te hototahitanga o te TPU ki te koiora, kāore he paitini, kāore he mate pāwera, kāore hoki e whakapataritari, e pai ai mō ngā tono hauora.
