Nā te tere o te tipu o te umanga pūngao hou—mai i ngā waka hiko (EV) ki ngā hanganga utu me te pūngao whakahou—kua nui ake te tono mahi mō ngā rauemi taura. Kei te piki haere te pai o te Thermoplastic Polyurethane (TPU) i te PVC me te XLPE nā tōna ngāwari, tōna pakari, me tōna āhua pai ki te taiao.
Heoi anō, kei te puta tonu ngā wero nui mō te TPU kāore i whakarerekētia e pā ana ki te mahi a te taura, te haumaru, me te whai huatanga o te utu:
• Teitei o te taunga waku → ka piri ngā taura tetahi ki tetahi, ka uaua ai te tāutanga me te whakahaere.
• Te pakaru me ngā karawarawa o te mata → te hekenga o te ataahua me te poto ake o te ora mahi.
• Ngā uauatanga tukatuka → ka ngoikore te āhua o te mata nā te piri i te wā e whakaputa ana, e whakapūtātia ana rānei.
• Te koroheketanga o waho → ka pāngia te maeneene me te pakari e te whakamahinga mō te wā roa.
Mō ngā kaihanga taura, ka pā tika ēnei take ki te wheako kaiwhakamahi, ki te tutuki i ngā whakaritenga haumaru, me te utu katoa o te mana whakahaere.
Me pēhea te arotau i ngā whakatakotoranga TPU mō ngā tono hiko me te pūngao
I whakarewahia e BASF, he kaiārahi o te ao i roto i te umanga matū, tētahi momo TPU hou — Elastollan® 1180A10WDM, i hangaia hei whakatutuki i ngā hiahia o ngā taura pou utu tere.
Ko tēnei taumata hou e tuku ana i:
• Te pakari, te ngāwari, me te ātete ki te kakahu kua whakarei ake.
• He ngawari ake te pā, he māmā ake te whakahaere, me te kore e whakararu i te kaha ā-ringa.
• Tino ātete ki te huarere me te ātete mura.
E whakaatu ana tēnei i te huarahi mārama o te umanga: He mea nui te whakarerekētanga TPU mō ngā taura hiko o te whakatipuranga e whai ake nei.
Otinga Whai Hua: Ngā Tāpiringa Hanga-Silicon Whakapai Ake i ngā Rauemi Taura TPU
He huarahi kua whakamātauhia ngā tāpiringa e ahu mai ana i te silicone hei whakarei ake i te mahi a te TPU me te pupuri tonu i ōna painga taiao me te miihini. Ina whakakotahihia ki roto i te TPU, ka tukuna e ēnei tāpiringa he whakapainga ine i roto i te kounga o te mata, te roa, me te ngāwari o te tukatuka.
Ngā Painga Matua o ngā Tāpiringa Silicone-Hangai i roto i ngā Taura TPU
He iti ake te waku o te mata → he maeneene ake ngā uhi taura, he iti ake te piri, he māmā ake te whakahaere.
Kua pai ake te ātete ki te karawarawa me te rakuraku → kua roa ake te ora ahakoa te piko pinepine.
Te whakapai ake i te ngāwari o te tukatuka → te whakaiti i te piri o te mate i te wā e tangohia ana, kia rite ai te kounga o te mata.
Pupuri ngāwari → ka mau tonu te pai o te piko o te TPU i ngā pāmahana iti.
Te tutuki i ngā whakaritenga tauwhiro → e tutuki katoa ana i ngā paerewa taiao RoHS me REACH.
Ngā Taupānga i te Wā Pūngao Hou
Mā te TPU whakarei ake i te tāpiringa Siloxane ka taea e ngā otinga taura te haumaru ake, te roa ake te mau, me te pumau ake puta noa i ngā tono tono nui:
Ngā Taura Utu EV → ātete ki te pakū, ngāwari ki raro ki te –40 °C, pono ki ngā āhuarangi katoa.
Ngā Taura Pūhiko me ngā Taura Ngaohiko Teitei → ātete matū/hinu, roa ake te ora, iti ake ngā utu tiaki.
Ngā Taura Hanganga Utu → te ātete pai ki ngā hihi UV me te huarere mō ngā teihana o waho.
Ngā Pūnaha Pūngao Whakahou → te pakari me te ngāwari mō te hiko o te rā me te hau mō te wā roa.
Mā te TPU kua whakarerekētia ki te silicone, ka taea e ngā kaihanga te whakaiti i ngā kereme pūtāhui, te whakaiti i ngā utu mana pupuri, me te whakarei ake i ngā kōtaha pumau.
Taunakitanga: Te Tohungatanga o SILIKE ki te Auahatanga Tāpiri TPU
I SILIKE, he tohunga mātou kingā otinga tāpiri e ahu mai ana i te silicone i hangaia mō ngā rauemi taura o te whakatupuranga e whai ake nei.
