He kirihou hangarau te nairona (polyamide, PA) me ōna āhuatanga miihini me te tukatuka tino pai, ā, ko te PA6 me te PA66 ngā momo polyamide noa.

Heoi, he iti ōna ātete ki te pāmahana teitei, he ngoikore te pumau o te tae, ā, he ngāwari ki te mimiti i te makuku me te waikura.

Hei tauira, mā tēnei tuhinga ka tirohia te whakapai ake i tōna ātete ki te koroheketanga. Kua whakaatuhia e ngā rangahau e pā ana ka taea te whakapai ake i te mahi a te PA6 mā te tāpiri i ngā antioxidants e tika ana me ētahi atu tāpiringa. Whai muri i te whakamātautau roa o te hihi UV me te whakamātautau pumau wera, kua whakaratohia e ngā huinga e whai ake nei he tiaki pai mō ngā āhuatanga miihini me te tae o te nairona:

①Ārai mate 1098 + Ārai mate 626

②Ārai mate 245 + Ārai mate 626

③Ārai mate 1098 + Ārai mate 168

Hei whakaroa i te roa o te mahi a te PA, he mea tika kia tāpirihia ētahi atu tāpiringa. Hei tauira, ko te tāpiri i ngā HALS hei whakarei ake i te pumau o te mārama,LS770ko tētahi o ngā kōwhiringa whai hua me te iti rawa o te pānga ki ngā āhuatanga miihini. I taua wā, kei te whakarato tā mātou kamupene i tētahi whakaū nairona maha-mahi e kiia nei koLS438, i whakapai ake i te tukatuka rewa o ngā polyamides, i whakarei ake i te wera me te pumau o te whakaahua mō te wā roa, ā, i whakapai ake hoki i te pumau o te tae.

Hei whakarei ake i te mā me te hipoki i te kōwhai, kua tāpirihia hoki te TiO2, te kikorangi moana-rahi, ngā mea whakamārama whatu, me ētahi atu ki te Polyamide.Whakamārama Whatu KSNhe kōwhiringa kounga teitei, ā, he ātete ki te pāmahana teitei te mea e whakaratohia ana e tā mātou kamupene.

Hei tāpiritanga,karbodiimide kaihoko ārai-waikuraka taea te tāpiri hei whakarei ake i tana mahi ārai-waikura me te whakaroa ake i tōna wā whakaoho waikura mā te mahi tahi me ētahi atu tāpiringa.

Ehara ngā whakaaro o runga ake nei i te aratohu hangarau, ā, me whakatau te mahi tuturu i runga anō i ngā mahi a te kaiwhakamahi.
