I a tātou e tūhura ana i ngā momo wira urethane rerekē, me kōrero tātou mō ō rātou āhuatanga ahurei me ngā āhuatanga tono. Ko te Polyurethane he rauemi mahi teitei. Nā ōna āhuatanga ā-tinana me te matū tino pai. He tūranga nui tōna i roto i te mara o te hanga wira.
Tuatahi. Me titiro tātou ki ngā wira polyurethane (TPU). He matua polypropylene, he nairona rānei ō ēnei wira. Mā te hangarau whakakoi werohanga tuarua, ka hangaia te mata wira polyurethane A ki te taha o waho o te matua. Ehara i te mea ko ngā āhuatanga o ngā wira TPU anake ko te tiaki i te papa, te mimiti i ngā wiri, te kore tohu me te kore paru. He ātete pai hoki ki te waku me te waikura. He kaha ki te hurihuri ngāwari ki runga i ngā momo mata. Hei tāpiri. Ka taea te whakarerekē i tōna tae kia rite ki te tono. Ka urutau ki ngā hiahia o ngā wā rerekē. Heoi, he mea tika kia mōhio i roto i te taiao wera. Ka whakaitihia te kaha kawenga o te wira TPU.
Ko te mahi e whai ake nei ko te ringihia he wira elastomer polyurethane (CPU). He rino, he konumohe rānei te pūtake o ēnei wira. He elastomer polyurethane whakamahana i hangaia mā te tauhohenga matū. Ka hangaia he mata wira i muri i te whakamaroke i ngā pāmahana teitei. He rite tonu ngā painga o ngā wira CPU ki te tiaki papa, te kore tohu me te kore poke. He ātete UV hoki, he ātete waku hoki, he mea pai mō ngā tono e hiahia ana ki te taumata teitei o te whakamarie whakahaere. Heoi, kāore e ātete ki te wai wera, te mamaoa wai, me ētahi atu... Nō reira me tūpato ina whakamahia i roto i ngā taiao motuhake.
Me kōrero tātou mō tētahi atu wira polyurethane (CPU) i whakarewaina. He mea hanga anō hoki ēnei wira i ngā elastomers polyurethane thermoset i whakarewahia ki te tauhohenga matū. He rite ngā painga ki ērā o te wira CPU kua whakaahuatia i runga ake nei, hei tauira, hei tiaki i te papa, hei ātete i te waku, me ētahi atu. He mea tino nui. He iti rawa te nekehanga tuturu, he iti te ātete hurihuri. Ka taea te tu atu ki ngā kawenga hihiri i ngā tere teitei. He pai mō te whakamahi i ngā āhuatanga tere teitei.
Hei whakamutunga. Me titiro tātou ki te wira polyurethane pahuka (PUE). Nā tōna hanganga moroiti ahurei, ka whakaatuhia e tēnei wira ngā āhuatanga pēnei i te iti o te mātotoru, te mama me te ngāwari ki te huri. He maha hoki ōna āhuatanga pai pēnei i te kawe kawenga nui, te ngāwari teitei me te ātete ki te takai. Nā ēnei āhuatanga o ngā wira PUE ka waiho hei rauemi pai mō ngā wira hurihuri. Ahakoa he mimiti oro me te pūngao, he whakaiti me te whakangāwari rānei i te wiri. Ka taea e rātou katoa te whakaatu i ō rātou painga ahurei.
Whānui. Ko ngā wira polyurethane, me ō rātou mahi tino pai me ngā momo kanorau, he whānuitia te whakamahinga i roto i ngā momo mara. Mai i ngā wira TPU e tiaki ana i te whenua me te mimiti i te ru. ki te ātete UV me te waku o te wira CPU. Haunga te iti o te kiato me te mama o te wira PUE. He mahi nui tā ia momo wira polyurethane i roto i tana ake mara. Te whiriwhiri i te wira urethane tika mō ō hiahia. Ehara i te mea ka whakapiki ake i te pai o te mahi anake. Ka whakarato hoki i tētahi wheako whakamarie me te haumaru ake.
