    Pono wau i kahi mea hoʻoulu kumu ikaika loa no ka hoʻopaʻa ʻana o CO2 i loko o nā carbonates cyclic. He kūpono anei ʻo DBU?

    ʻAe, ʻo DBU kekahi o nā kumu non-nucleophilic ikaika loa, kūpono no ka hoʻoulu ʻana i ka CO2 a me nā epoxides.

    ʻAʻole paʻa ka paʻa hydrolytic o kaʻu polyurethane elastomer. Hiki iā DBU ke kōkua?

    ʻAʻole, e paipai ʻo DBU i ka hydrolysis; e hoʻohana i kahi mea hoʻoulu tin a zinc paha.

    Pehea e hiki ai ke hoʻohana ʻia ʻo DBU ma ke ʻano he mea hoʻoulu trimerization no ka huʻa PIR hana kiʻekiʻe?

    E hoʻohui i ka 0.3–0.8 phr DBU me kahi mea hoʻoulu potassium e hoʻokō ai i ka nui o ka isocyanurate kiʻekiʻe loa (>30%).

    Hiki ke hoʻoheheʻe ʻia ʻo DBU i loko o nā polyols polyether maʻamau?

    ʻAe, hiki ke hui pū ʻia me ka hapa nui o nā polyols a ʻaʻole pono e lawelawe kūikawā.

    He lōʻihi loa ka manawa hoʻōla o kaʻu ʻōnaehana epoxy-amine ma ka mahana ambient. Hiki iā DBU ke hoʻolalelale iā ia?

    ʻAe, he mea hoʻolalelale ikaika ʻo DBU; e hoʻohana i ka 0.1–0.5 phr e hōʻemi nui i ke ola o ka ipu hao a me ka manawa hoʻōla.

    Ke hoʻololi nei anei ʻo DBU i ke kala ʻana o nā polyurethanes moakaka?

    Hiki iā ia ke hoʻoulu i ka melemele i ka hala ʻana o ka manawa ma muli o kona ʻano kumu ikaika; e pale i nā hoʻopili ʻana me ka ʻike maka maopopo.

    Hiki ke hoʻohana ʻia ʻo DBU e hoʻoulu i ka hopena o ka isocyanate me nā waiʻona ma nā wahi haʻahaʻa haʻahaʻa?

    ʻAe, ke hana mau nei ia ma lalo o 0°C, e lilo ia i mea pono no nā ʻōnaehana PU papa hoʻoilo.

    He aha ka pae hoʻohana maʻamau o DBU i loko o kahi ʻōnaehana hoʻolei polyurethane no nā ʻāpana nui?

    0.05–0.15 phr e pale aku i ka exotherm nui; e hoʻohui mau me kahi mea hoʻoulu gel no ke kaulike.

    Pono kaʻu mea kūʻai aku i kahi mea hoʻouluulu i loaʻa ʻole ka tin a i ʻole ka mercury. He koho maikaʻi anei ʻo DBU?

    ʻAe, he mea hoʻonui kumu ikaika ʻole ʻo DBU, kūpono no nā noi lapaʻau a me nā noi pili meaʻai ma hope o ka unuhi kūpono ʻana.

    Pehea e pono ai iaʻu ke mālama iā DBU i mea e pale aku ai i ka huhū o ka ʻili?

    E hoʻohana i nā mīkina lima a me nā maka aniani; he ʻawaʻawa ka DBU. E hoʻopau i nā mea i ninini ʻia me ka waikawa acetic dilute.
