He Kupu Whakataki ki ngā Tawhā Ātete Wairewa o ngā Rauemi TPU

Te ātete waikura o te TPUe pā ana ki tōna kaha ki te ātete i te "whakaekenga" a te makuku me te ārai i te hekenga o te mahi. Ka whakatauhia tēnei kaha e te hanganga matū me ngā tāpiringa o te TPU, ā, he tohu matua mō te aromatawai i tōna pono mō te wā roa i roto i ngā taiao makuku, i raro rānei i te wai.

Tauwehe Whakatau: He mea hanga ki te polyester vs.TPU e hangai ana ki te polyether

Ko te rerekētanga taketake o te ātete ki te waikura i ahu mai i te hanganga "wāhanga ngohengohe" i roto i te mekameka ngota.

• TPU hangai ki te polyester: Ka ngāwari te waikura o ngā here ester i roto i te mekameka ngota, ka heke te mahi i roto i ngā taiao wera me te makuku. Nō reira, he iti te ātete ki te waikura.
• TPU hangai ki te polyether: He pumau, he ātete hoki ngā here ether i roto i te mekameka ngota ki te waikura, ā, he tino pai te ātete ki te waikura. Nā tēnei ka waiho hei whiringa pai mō ngā tono i raro i te wai, i ngā tono haumākū nui rānei.

Hei whakarāpopototanga: Mō ngā tono e hiahia ana kia roa te whakapā atu ki te wai, ki ngā taiao makuku rānei, me whakarite kia whakamahia ngā TPU kei roto i te polyether.

Ngā Tohu Aromatawai Matua

Ko te ātete ki te waikura ka aromatawaihia mā roto i ngā whakamātautau koroheketanga tere, me te arotahi ki ngā tawhā matua e whai ake nei:

• Te Reiti Pupuri Kaha Kume: Ko te ōrau o te kaha kume e puritia ana i muri i te koroheketanga ki te whakataurite ki te uara taketake. Ko te pupuri teitei ake e tohu ana i te ātete pai ake ki te waikura; ko te tikanga e hiahiatia ana e te umanga he ≥80%.
• Huringa o te Toronga i te Wā Whati: E ine ana i te huringa o te ngāwari o ngā rauemi. Ko ngā huringa iti ake e tohu ana i te pumau ake o te mahi.
• Huringa o te Mārō: E whakaata ana i ngā huringa o te mārō o te mata. Ko ngā huringa iti ake e tohu ana i te pumau pai ake o te rauemi papatipu.
• Āhua Tirohanga: Mātakihia mēnā kei te mata o te tauira ngā tohu o te pirau pērā i te ngatata, te pupuhi, te kirikiri rānei.

Ngā Tikanga Whakamātautau me ngā Paerewa

Ka aromatawaihia te ātete ki te waikura mā roto i ngā whakamātautau koroheketanga tere. Ko ngā paerewa matua ko:

• ISO 4611: Paerewa ā-ao mō te koroheketanga o ngā kirihou.
• ASTM D570: Tikanga whakamātautau paerewa mō te mimiti wai o ngā kirihou.
• DIN 53366: Whakamahia hei whakarōpū i te pumau o te waikura o ngā rauemi.

Ko ngā tikanga whakamātautau noa ko te 70°C / 95% Makuku Whānau (RH) mō ngā rau ki ngā mano hāora, me te tauira i ia wā hei aroturuki i ngā huringa mahi.

Ngā Tikanga hei Whakapai ake i te Ātete ki te Wairewa

Mena kāore e ranea te ātete waikura o te TPU polyester-based, ka taea te whakamahi i ngā tikanga e whai ake nei:

1. Tāpirihia ngā Whakapūmau Waikawa: Ko tētahi o ngā tikanga tino whai hua ko te tāpiri i te polycarbodiimide (PCD) me ētahi atu rongoā ārai-waikawa. Ka "whakatika" ēnei i ngā mekameka ngota pakaru, ā, ka whakaroa i te pirau.
2. Arotauhia te Hanganga Ngota: Mā te whiriwhiri i ngā polyol polyester he taumaha ngota teitei ake, he mekameka roa ake, he hanganga peka rānei ka taea te whakapai ake i te pumau o te waikura ki tētahi taumata.

Whakarāpopototanga me ngā Tohutohu Kōwhiringa

• Kōwhiringa Matua: I ngā taiao makuku, me whakarite he TPU kei runga i te polyether.
• Pūtake Aromatawai: Aromatawaihia ngā momo TPU rerekē mā te whakatairite i ngā reiti pupuri kaha kume me ētahi atu raraunga mai i ngā whakamātautau koroheketanga.
• Ko te Taurite te Mea Matua: Kia mōhio koe he iti ake te kaha ā-ringa me te ātete wera o ngā TPU e ahu mai ana i te polyether ki ērā o ngā momo polyester. Me whakatutuki he taurite i waenga i te ātete waikura me ngā āhuatanga ā-ringa.

Mā te mārama ki ēnei tawhā ka āwhina i a koe ki te whiriwhiri i te rauemi TPU tika mō tō hua, kia mau ai te pono mō te wā roa i roto i te taiao e hiahiatia ana.
