    Ngā Pātai Auau

    He paninga polyurethane wai taku e whakaputa ana, he iti te haunga. Me pēhea te āwhina a te DPA?

    He amine iti te kakara, he tauhohe te DPA e whakaiti ana i te kakara amine i te wā e whakamahia ana, me muri hoki i te hanganga o te kiriata.

    He ngoikore te kaha haehae o taku elastomer polyurethane. Ka taea e te DPA te whakapai ake?

    Ae, ka taea e tōna hanganga diisopropanolamine te whakanui ake i te kiato hononga whakawhiti me te ātete ki te haehae ina whakamahia i te 0.2–0.5 phr.

    He aha te horopeta noa mō te DPA i roto i te hiri polyurethane hei whakapai ake i te piri ki te raima?

    0.3–0.6 phr; ka whakarei ake i te mākū me te here matū ki ngā mata kohuke.

    Ka taea te whakamahi i te DPA hei tāpiri-whakakorikori i roto i ngā pahuka rehu polyurethane hei whakaiti i te haunga?

    Āe, ka āwhina i te whakaiti i te piki me te heke o te amine; he maha ngā wā ka konatunatua ki te MOFAN 33LV.

    He ngoikore te ātete wera o taku piripiri polyurethane mō te PVC. Me pēhea te whakapai ake?

    Tāpirihia te DPA (0.4 phr) hei whakanui ake i te mātotoru hononga whakawhiti, kia piki ake ai te pāmahana whakapiko wera.

    He hototahi te DPA ki ngā pūnaha whakaora makuku?

    Ka taea te whakamahi, engari nā te mea kei roto ngā rōpū OH, ka tauhohe ki te isocyanate. Whakamahia i roto i ngā pūnaha wāhanga-rua anake.

    He pēhea te whakataurite o te DPA ki te triethanolamine (TEOA) hei hononga whakawhiti?

    He pai ake te whakakorikori a te DPA, he ngāwari ake hoki te hononga whakawhiti; ko te TEOA he hononga whakawhiti me te ngoikore o te mahi whakakorikori.

    He puhoi te whakaoranga o taku pahuka polyurethane mō te takai i muri i te pēhanga. Ka taea e te DPA te whakatika i tēnei?

    Āe, whakapiki ake i te DPA ki te 0.2–0.3 phr hei whakarei ake i te hanganga whatunga pīngore.

    Ka taea te whakamahi i te DPA i roto i ngā pūnaha epoxy hei whakapai ake i te ngāwari?

    Āe, hei whakarerekētanga ka taea te whakaiti i te pakarukaru me te kore e whakaroa i te whakapakeketanga.

    Kia pēhea te roa o te oranga o tētahi ranunga polyol kei roto ko te DPA?

    Kia ono marama te roa ina rongoatia ki roto i tētahi ipu maroke, hiritia.
