Ngā Whakatika Wai mō te Tātuhi Hihiko Matua

Te uretana wai-moana he mīhini āhuarangi e whakamahia tonu hei whakapūmau i ngā kōwhiringa moana, tae atu ki te whakahoki pai ki te taiao. Ki te aoheke noa iho, kei te whakamahi ngā uretana moana matua i mua ki ngā whakahaere wai-tau, nā te mea ka whakamahi te putunga wai-moana i te wai hei take matua, tērā pea ka tohe i ngā pūngao whakawehewehea (VOC). I te taiao, ko te uretana wai-moana he tīmatanga whakaaetanga anake mō ngā kaupapa whakapūmau moana. Ki te tohe i ngā pūngao whakawehewehea, ka taea te whakahoki pai ki te taiao, ka tohe hoki i ngā mate hauora e pā ana ki ngā tauira o ngā pūngao whakawehewehea, tae atu ki te mea ka whai mana ki te oranga o ngā kaiwhakatūpato me te whenua tuatahitia. I te tirohanga mahi, ka hangaia te uretana wai-moana hei whakatika i ngā momo huringa moe. Ka tukua e ia he whakamahara pai ki te wai, ki te rā, ki te wai-kai-pakihi, me ngā huringa urupa. Ki te whakatakoto ki ngā wharekai rakau moana pērā i ngā waka, ngā paepae, ngā pae, me ngā wharekai moana, ka hangaia e ia he whiu pai, he whakapono kore hei whakatika i te whakapenapena wai, te whakamate rangi-UV, me te mate rakau. Ko te take uretana i roto i te pūmau ka whakamahia hei whakatika i tana whakamahara pai ki te whakapuku, tae atu ki te mea ka taea e te mata o te pūmau te whai mana i te whakamahi tūmu tūmu me te whakapā mai ki ngā huinga kore. Ko te kawa whakatakoto o te uretana wai-moana ka whai ake i ēnei whakarite. Nā tōna ahurea wai-moana, ka kitea e ia he wā whakapuku iti i runga i ngā pūngao wai-tau, ā tōna waewae i ngā wā wetewete. He mea nui te whakarite ā-waho hei whakamahi pai; ina whakauru ai tēnei, ka whakamahi kia pai te whakapakari i te upoko, ka whakamahi kia pai te whakapakari i te oneone, me te whakapakari i ngā pūmau kē, ka whakamahi kia pai te whakapakari i te oneone, ka whakamahi kia pai te whakapakari i te oneone. Ka whakamahi ngā kauwhau e whai ana kia pai te whakapakari i te oneone, ka whakamahi kia pai te whakapakari i te oneone, ka whakamahi kia pai te whakapakari i te oneone. Ka whakamahi ngā kauwhau e whai ana kia pai te whakapakari i te oneone, ka whakamahi kia pai te whakapakari i te oneone, ka whakamahi kia pai te whakapakari i te oneone.
