Te mea ngaro o te kiriata TPU: te hanganga, te tukanga me te tātari tono
He mea nui te kiriata TPU, he rauemi pūmua mahi-teitei, i roto i ngā mara maha nā ōna āhuatanga ā-tinana me ā-matū ahurei. Ka rukuhia e tēnei tuhinga ngā rauemi hanganga, ngā tukanga whakaputa, ngā āhuatanga, me ngā whakamahinga o te kiriata TPU, ka haria koe ki tētahi haerenga ki te taupānga...Pānuihia atu -
Kua whakawhanakehia e ngā kairangahau tētahi momo rauemi hou o te elastomer polyurethane thermoplastic (TPU) hei ārai i te ru.
Kua whakawhanakehia e ngā kairangahau o te Whare Wānanga o Colorado, Boulder, me te Sandia National Laboratory tētahi rauemi hou e mimiti ana i te ru, he whanaketanga hou tēnei ka taea te whakarerekē i te haumaru o ngā hua mai i ngā taputapu hākinakina ki te kawe waka. Ko tēnei taputapu hou kua hoahoatia...Pānuihia atu -
Ngā huarahi matua mō te whanaketanga o te TPU ā muri ake nei
He elastomer thermoplastic polyurethane te TPU, he copolymer poraka maha-wāhanga i hangaia mai i ngā diisocyanates, polyols, me ngā whakaroa mekameka. Hei elastomer mahi-teitei, he whānuitia ngā huarahi hua o te TPU, ā, e whakamahia whānuitia ana i roto i ngā mea e hiahiatia ana i ia rā, i ngā taputapu hākinakina, i ngā taonga takaro, i ngā mea whakapaipai...Pānuihia atu -
Ko te poitūkohu TPU hou kāore he hau polymer e ārahi ana i tētahi momo hou i roto i ngā hākinakina.
I roto i te ao whānui o ngā hākinakina pōro, he mea nui tonu te poitūkohu, ā, nā te putanga mai o te poitūkohu TPU kore-hau polymer kua puta mai he whanaketanga hou me ngā huringa ki te poitūkohu. I taua wā anō, kua puta mai hoki he ia hou i roto i te mākete taonga hākinakina, e hanga ana i te hau polymer...Pānuihia atu -
Ko te rerekētanga i waenga i te momo TPU polyether me te momo polyester
Ko te rerekētanga i waenga i te momo TPU polyether me te momo polyester TPU ka taea te wehewehe kia rua ngā momo: te momo polyether me te momo polyester. E ai ki ngā whakaritenga rerekē o ngā tono hua, me whiriwhiri ngā momo TPU rerekē. Hei tauira, ki te ātete ngā whakaritenga mō te hydrolysis...Pānuihia atu -
Ngā painga me ngā ngoikoretanga o ngā kete waea TPU
TPU， Ko te ingoa katoa ko te elastomer polyurethane thermoplastic, he rauemi polymer he tino ngāwari me te ātete ki te kakahu. He iti ake te pāmahana whakawhiti karāhe i te pāmahana rūma, ā, he nui ake i te 50% tōna roa i te whati. Nō reira, ka taea e ia te whakahoki mai i tōna āhua taketake...Pānuihia atu
