    Ibibazo Bikunze Kubazwa

    Nkora imiti ifunga polyurethane igabanya ubushuhe mu buryo bumwe. DMDE ikora ite?

    DMDE ni catalyst ihishe; ikora gusa iyo hari ubushuhe, bigatuma iguma mu bubiko igihe kirekire (≥ amezi 12).

    Uruhu rwanjye rufunga vuba cyane, rugasiga iminkanyari. Nabigenza nte ngomba kuvugurura?

    Gabanya DMDE kuri 0.2–0.3 phr kugira ngo ugabanye umuvuduko wo kuvura ubuso, biguha umwanya uhagije wo kugorora.

    Ese DMDE ishobora gukoreshwa mu mavuta ya polyurethane ashyushye (HMPUR)?

    Yego, ni yo ngamba ikoreshwa mu nganda mu kuvura ubushuhe bwa HMPUR, itanga ubushyuhe buhamye kuri 120°C n'ubukonje bw'icyatsi vuba.

    Ni iki gipimo gisanzwe cya DMDE mu gipfundikizo cy'ubutaka gifite igice kimwe?

    0.5–1.0 phr (ishingiye kuri prepolymer) mu gihe cy'amasaha 2–4 ​​nta gufatisha ku gipimo cya 50%.

    Elastomer yanjye ivura ubushuhe ifite utubyimba bitewe no kurekura CO2 vuba cyane. Nigute nakosora?

    Gabanya DMDE kuri 0.1–0.2 phr hanyuma wongereho agakoresho ko gukamura ubushuhe nka p-TSI.

    Ese DMDE itera umuhondo mu bifunga bifite ibara ryoroheje?

    Ni ntoya; ni ikomoka kuri morpholine kandi izwiho kuba ifite ibara rihamye.

    Ese DMDE ishobora gukoreshwa hamwe n'utuyunguruzo twumye nk'udukoko?

    Yego, ariko menya neza ko utuntu two gucukura tudafata DMDE; koresha uburyo bwo gusya cyangwa uvange mbere na plasticizer.

    Ifuro ryanjye rifunga ifuro ry'igice kimwe (ifuro ry'ikoti) ntirimara igihe kirekire. Ese DMDE ishobora kurikongera?

    Yego, imiti ishingiye kuri DMDE ishobora kumara amezi 18-24 mu macupa ya aerosol.

    Ni iyihe nyungu ya DMDE ugereranyije na DBTDL mu buryo bwo kuvura ubushuhe?

    DMDE ntabwo ari uburozi (nta tin) kandi ntabwo itera hydrolysis y'amatsinda ya ester muri polyester polyols.

    Nigute nakongera umuvuduko wo gukira kw'igitambaro cy'igice kimwe mu gihe cy'ubukonje kandi cyumye?

    Ongera DMDE kuri 1.2–1.5 phr hanyuma wongereho icyuma gihutisha ubushuhe nk'amazi atanga ibinyabutabire.
