    Whakaahuatanga

    Ko te MOFAN DBU he amine tuatoru e kaha ana ki te whakatairanga i te tauhohenga urethane (polyol-isocyanate) i roto i te pahuka pūtau-iti haurua-ngāwari, me ngā tono paninga, piripiri, hiri me te elastomer. He tino kaha te kaha ki te whakarewa, he iti te kakara, ā, e whakamahia ana i roto i ngā whakatakotoranga kei roto ngā isocyanate aliphatic nā te mea e hiahiatia ana he whakakorikori tino kaha nā te mea he iti ake te kaha o te mahi i ngā isocyanate kakara.

    Tono

    Kei roto te MOFAN DBU i te pahuka pūtau-iti āhua-ngāwari, ā, kei roto hoki i ngā tono paninga, piripiri, hiri me te elastomer.

    Te whakahaere me te rokiroki

    Ngā whakatūpato mō te whakahaere haumaru
    Kia tino pai te hauhautanga o ngā toa me ngā wāhi mahi. Kia rite ki ngā tikanga pai mō te akuaku ahumahi me te haumaru. Kaua e kai, kaua e inu, kaua hoki e momi hikareti i te wā e whakamahi ana. Me horoi ō ringaringa me/ranei ō kanohi i mua i ngā okiokinga me te mutunga o te huringa mahi.

    Te parenga ki te ahi me te pahūtanga
    Ārai i te hiko pūmau - me waiho kia mārama ngā pūtake mura - me waiho kia tata mai ngā tinei ahi.

    Ngā tikanga mō te rokiroki haumaru, tae atu ki ngā āhuatanga kore hototahi
    Wehea mai i ngā waikawa me ngā matū hanga waikawa.
    Ētahi atu kōrero mō ngā tikanga rokiroki: Puritia te ipu kia katia rawatia ki tētahi wāhi hauhautanga, kia pai te hauhautanga.

    Ngā Pātai Auau

    Me hiahia au ki tētahi whakakorikori turanga tino kaha hei whakapiri i te CO2 ki roto i ngā warowaihā hurihuri. He pai te DBU?

    Āe, ko te DBU tētahi o ngā turanga kaha rawa atu kāore e pai ki te nucleophilic, he mea tino pai mō te whakahohe i te CO2 me ngā epoxide.

    Kāore i te tino pakari te wai o taku elastomer polyurethane. Ka taea e te DBU te āwhina?

    Kāo, ka whakatairangahia e te DBU te waikura; whakamahia he whakakōkī tine, he konutea rānei hei utu.

    Me pēhea te whakamahi i te DBU hei whakakorikori trimerization mō te pahuka PIR mahi teitei?

    Tāpirihia te 0.3–0.8 phr DBU me te whakakorikori pāhare pāporo hei whakatutuki i te ihirangi isocyanurate tino teitei (>30%).

    Ka wairewa te DBU i roto i ngā polyol polyether noa?

    Ae, ka taea te whakaranu me te nuinga o ngā polyol, ā, kāore e hiahiatia he whakamahinga motuhake.

    He roa rawa te wā e ora ai taku pūnaha epoxy-amine i te pāmahana taiao. Ka taea e te DBU te whakateretere ake?

    Ae, he kaha te whakateretere a DBU; whakamahia te 0.1–0.5 phr hei whakaiti i te roa o te wā e pau ai te oneone me te wā e mātao ai.

    Ka puta te rerekētanga o te tae i roto i ngā polyurethane mārama nā te DBU?

    Ka taea e ia te whakakōwhai i te roanga o te wā nā tōna kaha ki te waiho hei matū taketake; kaua e whakamahia mō ngā whakamahinga mārama-kanohi.

    Ka taea te whakamahi i te DBU hei whakatere i te tauhohenga o te isocyanate me ngā waipiro i roto i ngā taiao pāmahana iti?

    Ae, kei te kaha tonu ahakoa i raro i te 0°C, ā, he mea whai hua mō ngā pūnaha PU mō te takurua.

    He aha te taumata whakamahinga noa o te DBU i roto i te pūnaha whakarewa polyurethane mō ngā wāhanga nunui?

    0.05–0.15 phr hei karo i te wera nui rawa; me whakakotahi tonu ki tētahi whakakorikori tiēre hei taurite.

    E hiahia ana taku kiritaki ki tētahi matū whakakorikori kāore he tine, he mercury rānei kei roto. He pai te DBU hei whakakapi?

    Āe, he whakakorikori turanga kaha kāore he konganuku a DBU, he mea e tika ana mō ngā mahi hauora me ngā mahi pa-kai i muri i te tango tika.

    Me pēhea te whakahaere i te DBU kia kore ai e puta te riri o te kiri?

    Whakamahia he karapu me he mōhiti kanohi; he waikura te DBU. Whakakorehia ngā turuturu ki te waikawa acetic waimeha.
