Atlanta, GA – Mai i te 30 o Hepetema ki te 2 o Oketopa, ka tū te Huihuinga Hangarau Polyurethanes 2024 i te Omni Hotel i Centennial Park, ka huihui mai ngā tohunga ngaio me ngā tohunga matua o te umanga polyurethane o te ao katoa. Nā te Pokapū mō te Ahumahi Polyurethanes (CPI) o te Kaunihera Matū o Amerika i whakarite, ko te whāinga o te hui he whakarato i tētahi tūāpapa mō ngā wā ako me te whakaatu i ngā auahatanga hou o te matū polyurethane.

E mōhiotia ana ko ngā polyurethane tētahi o ngā rauemi kirihou tino maha ngā whakamahinga e wātea ana i ēnei rā. Nā ō rātou āhuatanga matū ahurei ka taea te whakarite mō ngā momo mahi maha, te whakaoti rapanga uaua, me te hanga kia rite ki ngā āhua rerekē. Mā tēnei urutau ka whakarei ake i ngā hua ahumahi me ngā hua kaihoko, ka tāpirihia he whakamarie, he mahana, me te whai wāhi ki te oranga o ia rā.

Ko te hanga polyurethane he tauhohenga matū i waenga i ngā polyol—ngā waipiro he nui atu i te rua ngā rōpū hydroxyl tauhohe—me ngā diisocyanate, ngā isocyanate polymeric rānei, e āwhinahia ana e ngā whakakorikori me ngā tāpiringa e tika ana. Mā te kanorau o ngā diisocyanate me ngā polyol e wātea ana ka taea e ngā kaihanga te waihanga i tētahi whānuitanga o ngā rauemi kua whakaritea mō ngā tono motuhake, ka noho ko ngā polyurethane he mea nui ki ngā ahumahi maha.

Kei ngā wāhi katoa ngā polyurethane i te ao hou, e kitea ana i roto i ngā momo hua mai i ngā moenga me ngā tūru ki ngā rauemi whakamahana, ngā paninga wai, me ngā peita. E whakamahia ana hoki ēnei i roto i ngā elastomers pakari, pērā i ngā wira mata roera, ngā taonga takaro pahuka ngohengohe ngāwari, me ngā muka rapa. Ko tō rātou noho whānui e whakaatu ana i tō rātou hiranga ki te whakarei ake i te mahi a te hua me te whakamarie o te kaihoko.

Ko te matū kei muri i te hanga polyurethane e rua ngā rauemi matua: te methylene diphenyl diisocyanate (MDI) me te toluene diisocyanate (TDI). Ka tauhohe ēnei matū ki te wai i roto i te taiao hei hanga polyureas totoka kore e mahi, e whakaatu ana i te maha o ngā mahi me te urutau o te matū polyurethane.

Ka whakaatuhia e te Huihuinga Hangarau Polyurethanes 2024 he whānuitanga o ngā wāhanga kua hangaia hei whakaako i ngā tāngata e whai wāhi ana ki ngā whanaketanga hou o te ao. Ka matapakihia e ngā tohunga ngā au hou, ngā tono auaha, me te heke mai o te hangarau polyurethane, ka whakaratohia he māramatanga whai hua mō ngā tohunga o te umanga.

I te whakatata mai o te hui, ka akiakihia ngā kaiuru ki te whai wāhi atu ki ngā hoa mahi, ki te whakawhitiwhiti mōhiotanga, me te tūhura i ngā whai wāhitanga hou i roto i te rāngai polyurethane. He huihuinga nui tēnei mō te hunga e whai wāhi ana ki te whakawhanake me te whakamahi i ngā rauemi polyurethane.
