    Ibisobanuro

    MOFAN DBU ni amine ya gatatu itera imbere cyane mu gukora urethane (polyol-isocyanate) mu ifuro rito rihinduka, no mu gusiga, gufunga, gufunga no gukoresha elastomer. Igaragaza ubushobozi bukomeye bwo gusiga, itanga impumuro nke kandi ikoreshwa mu buryo burimo isocyanate za aliphatic kuko zikenera catalysts zikomeye cyane kuko zidakora cyane nka isocyanate zinuka.

    Porogaramu

    MOFAN DBU iri mu ifuro rishobora guhinduka mu turemangingo duto, no mu gusiga, gufunga, gufunga no gukoresha elastomer.

    Ibibazo Bikunze Kubazwa

    Nkeneye catalyst ikomeye cyane kugira ngo CO2 ifatanye muri karubone zizunguruka. Ese DBU irakwiriye?

    Yego, DBU ni imwe mu misemburo ikomeye idakoresha nucleus, ikaba ari nziza cyane mu gutuma CO2 na epoxides bitangira gukora.

    Elastomer yanjye ya polyurethane ifite ubushobozi buke bwo gupima hydrolytic. Ese DBU ishobora kumfasha?

    Oya, DBU yateza imbere hydrolysis; ahubwo koresha tin cyangwa zinc catalyst.

    Ni gute DBU yakoreshwa nk'igitera imbaraga cyo kugabanya ubushyuhe mu gupima ifuro rya PIR rifite imikorere myiza?

    Ongeraho DBU ya 0.3–0.8 phr hamwe na katalyst ya potasiyumu kugira ngo ubone isocyanurate nyinshi cyane (> 30%).

    Ese DBU ishobora gushonga muri polyols zisanzwe za polyether?

    Yego, iravangavanze na polyol nyinshi kandi ntisaba uburyo bwihariye bwo kuyikoresha.

    Sisitemu yanjye ya epoxy-amine ifite igihe kirekire cyane cyo kuyivura iyo ubushyuhe buri mu kirere. Ese DBU ishobora kuyihutisha?

    Yego, DBU ni umuvuduko ukomeye; koresha 0.1–0.5 phr kugira ngo ugabanye cyane igihe cyo kumara inkono no kuyivura.

    Ese DBU itera ibara ry'ibara muri polyurethane isobanutse?

    Ishobora gutera umuhondo uko igihe kigenda gihita bitewe nuko isanzwe; irinde ko ikoreshwa mu buryo bugaragara neza.

    Ese DBU ishobora gukoreshwa mu gukurura ingaruka za isocyanate hamwe na alcool mu bushyuhe buke?

    Yego, ikomeza gukora ndetse no munsi ya 0°C, bigatuma iba ingirakamaro kuri sisitemu za PU zo mu gihe cy'itumba.

    Ni uruhe rwego rusanzwe rwa DBU mu buryo bwo gukata polyurethane ku bice binini?

    0.05–0.15 phr kugira ngo wirinde exotherm ikabije; buri gihe shyira hamwe na gel catalyst kugira ngo urebe neza.

    Umukiriya wanjye akeneye katalisiti idafite tin cyangwa mercure. Ese DBU ni ubundi buryo bwiza?

    Yego, DBU ni imashini ikomeye idafite icyuma, ikwiriye gukoreshwa mu buvuzi no mu biryo nyuma yo kuyikuramo neza.

    Nigute nakwitwara kugira ngo wirinde kubabara uruhu?

    Koresha uturindantoki n'amadarubindi kuko DBU irangiza. Hindura ibyamenetse ukoresheje aside asetiki ivanze.
