    Ngā Pātai Auau

    He kaihanga hiri polyurethane kotahi-wāhanga e whakamahi ana ahau hei ārai i te makuku. Me pēhea te mahi a te DMDE?

    He whakakorikori huna te DMDE; ka kaha anake ina pāngia e te makuku, ā, ka roa te rokiroki (≥12 marama).

    Ka tere rawa te tihore o taku hiri, ka waiho ngā kita. Me pēhea te whakatika?

    Whakaitihia te DMDE ki te 0.2–0.3 phr hei whakaroa i te pakari o te mata, kia nui ai te wā mō te whakataurite.

    Ka taea te whakamahi i te DMDE i roto i ngā piripiri polyurethane rewa-wera (HMPUR)?

    Ae, koinei te paerewa ahumahi mō te HMPUR whakaora-makuku, e whakarato ana i te matotoru pumau i te 120°C me te kaha matomato tere.

    He aha te horopeta noa o te DMDE i roto i te paninga papa kotahi-wāhanga?

    0.5–1.0 phr (i runga i te prepolymer) mō te wā kore-pā o te 2–4 hāora i te 50% RH.

    He mirumiru kei roto i taku elastomer whakamakuku nā te tere rawa o te tukunga o te CO2. Me pēhea te whakatika?

    Whakaitihia te DMDE ki te 0.1–0.2 phr ka tāpirihia he mea tango makuku pēnei i te p-TSI.

    Ka puta te kōwhai i roto i ngā hiri mārama nā te DMDE?

    He iti noa iho; he mea hanga mai i te morpholine, ā, e mōhiotia ana mō tōna pumau pai o te tae.

    Ka taea te whakamahi tahi i te DMDE me tētahi tātari irahiko maroke pēnei i te tātari ngota?

    Āe, engari kia tino mōhio kei mimiti te DMDE i ngā tātari; whakamahia he āhua whakapiri, he whakaranu rānei i mua me te plasticizer.

    He iti te roa o te wā e penapena ai taku hiri pahuka kotahi-wāhanga (pahuka kēne). Ka taea e te DMDE te whakaroa ake?

    Ae, ka taea e ngā whakatakotoranga e hangai ana ki te DMDE te pupuri i roto i ngā kēne aerosol mō te 18–24 marama.

    He aha te painga o te DMDE i runga i te DBTDL i roto i ngā pūnaha whakaora makuku?

    Kāore he paitini o te DMDE (kāore he tine) ā, kāore hoki e whakapōrearea i ngā rōpū ester i roto i ngā polyol polyester.

    Me pēhea te whakanui ake i te tere o te maroke o tētahi paninga kotahi-wāhanga i te hotoke makariri, maroke?
