Ngā Āhuatanga Ārai-Wai me te Āhei-Makuku o te Kiriata TPU

Ko te mahi matua oKiriata Polyurethane Thermoplastic (TPU)Kei roto i ōna āhuatanga tino pai mō te ārai wai me te uru ki te makuku—ka taea e ia te aukati i te urunga o te wai wai, me te tuku hoki i ngā ngota kohu wai (te werawera, te werawera) kia puta.

1. Ngā Tohu Mahi me ngā Paerewa

1. Ātete ki te Pēhanga Wai (Ātete ki te Pēhanga Wai):
   • Tohu: E ine ana i te kaha o te kiriata ki te ātete i te pēhanga wai o waho, e inehia ana i roto i ngā kilopascal (kPa) me ngā mirimita o te pou wai (mmH₂O). Ko te uara teitei ake e tohu ana i te kaha ake o te mahi ā-wai. Hei tauira, ko ngā kākahu o waho noa me ≥13 kPa, ko ngā taputapu ngaio ia me ≥50 kPa.
   • Paerewa Whakamātautau: E whakamatautauria ana mā te whakamahi i te ISO 811, ASTM D751 rānei (Tikanga Kaha Pahū). Kei roto i tēnei ko te whakanui tonu i te pēhanga wai i tetahi taha o te kiriata kia puta rā anō ngā pata wai ki tērā taha, me te tuhi i te uara pēhanga i taua wāhi.
2. Te Āheinga o te Makuku (Te Tukunga o te Kohu):
   • Tohu: E ine ana i te papatipu o te mamaoa wai e rere ana i roto i te horahanga kotahi o te kiriata mō ia wā kotahi, e whakaaturia ana i roto i te karamu mō ia mita tapawha mō ia 24 hāora (karamu/m²/24h). Ko te uara teitei ake e tohu ana i te pai ake o te manawa me te marara o te werawera. I te nuinga o te wā, ko te uara neke atu i te 5000 karamu/m²/24h e kiia ana he tino manawa.
   • Paerewa Whakamātautau: E rua ngā tikanga matua:
     • Tikanga Kapu Tū (Tikanga Whakamaroke): hei tauira, ASTM E96 BW. Ka whakatakotoria he whakamaroke ki roto i tētahi kapu, ka hiritia ki te kiriata, ā, ka inehia te nui o te mamaoa wai e mimitihia ana i raro i ngā āhuatanga pāmahana me te haumākū motuhake. He tata ake ngā hua ki ngā āhuatanga pakaru tūturu.
     • Tikanga Kapu Hurihuri (Tikanga Wai): hei tauira, ISO 15496. Ka whakatakotoria te wai ki roto i tētahi kapu, ka hurihia, ka hiritia ki te kiriata, ā, ka inehia te nui o te mamaoa wai e mimiti ana i roto i te kiriata. He tere ake tēnei tikanga, ā, he maha ngā wā ka whakamahia hei whakahaere i te kounga.

2. Te Mātāpono Mahi

Ngā āhuatanga ātete-wai me te uru-makuku oKiriata TPUkāore e tutuki mā roto i ngā pūwero ā-tinana engari e whakawhirinaki ana ki te mahi taumata-ngota o ōna wāhanga mekameka hydrophilic:

• Ārai wai: He matotoru te kiriata, kāore he pūwero; kāore e taea e te wai wai te haere nā tōna kukū mata me te hanganga ngota o te kiriata.
• Āhei te Pūwero i te Makuku: Kei roto i te pūmua ngā rōpū wai-aroha (hei tauira, -NHCOO-). Ka "hopu" ēnei rōpū i ngā ngota kohu wai e mimiti ana mai i te kiri ki roto. Kātahi, mā te "nekehanga wāhanga" o ngā mekameka pūmua, ka "tukuna" ngā ngota wai i roto ki te taiao o waho i ia taahiraa.

3. Ngā Tikanga Whakamātautau

1. Whakamātautau Pēhanga Waipēhi: Whakamahia hei ine tika i te pēhanga rohe ā-wai o te kiriata, te papanga rānei.
2. Kapu Āheitanga Makuku: Ka whakamahia i roto i tētahi rūma pāmahana me te makuku pumau hei ine i te tere tuku mamaoa makuku (MVTR) mā te whakamahi i te tikanga kapu poutū, kapu huripokitia rānei.

4. Ngā tono

Mā te whakamahi i ēnei āhuatanga,Kiriata TPUkoinei te kōwhiringa pai mō ngā tono maha o te taumata teitei:

• Kākahu o Waho: He mea nui mō ngā koti pakari, ngā kākahu hīkoi, me ngā tarau hikoi, hei whakarite kia maroke, kia whakamarie hoki te hunga e hiahia ana ki te mahi o waho i te hau me te ua.
• Parenga Hauora: Whakamahia i roto i ngā kākahu pokanga me ngā kākahu tiaki hei aukati i te toto me ngā wai o te tinana (ātete wai) me te tuku i te werawera i puta mai i ngā kaimahi hauora kia puta, hei whakaiti i te ahotea wera.
• Ngā Kākahu Whakangungu Tinei Ahi me te Hōia: Ka whakarato i te tiakitanga i roto i ngā taiao tino kino, me te ātete ki te ahi, te wai, me ngā matū, me te kaha hoki ki te manawa kia mau tonu ai te nekenekehanga me te mahi.
• Ngā Rauemi Hu: Hei arai tōkena ātete wai (pūtu) hei pupuri i ngā waewae kia maroke i te ua, me te ārai hoki i te hanga wera me te makuku o roto.

Hei whakarāpopototanga, mā tōna hanganga ā-tinana me te matū ahurei, ka taurite pai te kiriata TPU i ngā hiahia taupatupatu o te "ātete wai" me te "manawa", ka waiho hei rauemi matua e kore e taea te whakakapi i roto i te ao o ngā kakahu mahi-teitei.
