    Ibisobanuro

    MOFAN TMEDA ni amine idafite ibara, ivanze n'ibinyamisogwe, ifite impumuro idasanzwe ya amine. Irashongesha mu mazi, alcool ya ethyl, n'indi misokoro y'ibinyabuzima. Ikoreshwa nk'igice cy'ingenzi mu guhuza ibinyabuzima. Ikoreshwa kandi nk'umusemburo uhuza ibyuma bya polyurethane.

    Porogaramu

    MOFAN TMEDA, Tetramethylethylenediamine ni catalyst ikora neza kandi ikaba na catalyst ikora neza ya gel, ishobora gukoreshwa mu gushonga ifuro ryoroshye rya thermoplastic, polyurethane semi foam na rigid foam kugira ngo uruhu rurusheho kumera neza, kandi ishobora gukoreshwa nk'abafasha ba MOFAN 33LV.

    Bika kure y'aho umuriro uturuka - Ntukanywe itabi. Fata ingamba zo kwirinda ko amazi yangirika. Irinde ko byagera ku ruhu no ku maso.
    Ambara imyenda yose irinda umuntu igihe kirekire cyangwa igihe kinini. Tanga umwuka uhagije, harimo n'aho uherereye hakwiye.gukurura, kugira ngo harebwe ko ntarengwa y'aho umuntu ashobora kugera ku kazi kawe. Iyo umwuka udahagije, wirinde guhumeka nezabigomba gutangwa.

    Ibibazo Bikunze Kubazwa

    Nkora ifuro ryoroshye kandi nshaka ko rizamuka vuba ritacitse. TMEDA yamfasha ite?

    TMEDA ni catalyst ikora vuba; koresha 0.05–0.15 phr hamwe na catalyst ya gel iringaniye nka TEDA kugira ngo wirinde gucikamo ibice.

    Ese TMEDA ishobora kugabanya ingano y'amazi akenewe kugira ngo hagerwe ku bucucike bw'ifuro ry'umushongi?

    Si mu buryo butaziguye, ahubwo imikorere yayo ikomeye ya catalytic igufasha gukomeza gukora reactivation ndetse no ku rugero rwo hasi rw'amazi (exotherm yo hasi).

    Igipfundikizo cyanjye cya epoxy gifata igihe kirekire cyane kugira ngo gikomere kuri 10°C. Ese TMEDA izabyihutisha?

    Yego, TMEDA ni umuvuduko mwiza ku buryo bwa epoxy-amine, cyane cyane iyo ubushyuhe buri hasi.

    Ni ubuhe buryo bwiza bwo kwirinda gushya mu buryo bw'amazi menshi kandi bufite TMEDA nyinshi?

    Gabanya TMEDA kugeza munsi ya 0.1 phr hanyuma wongeremo antioxydant; tekereza kandi gusimbuza igice cya TMEDA na MOFAN A1.

    Ese TMEDA itera indabyo zikomeye za amine ku buso bw'ifuro?

    Ifite impinduka nyinshi, bityo ishobora kugaragara ku buso. Koresha urugero ruto cyangwa nyuma yo gukira kuri 50°C mu gihe cy'amasaha 2 kugira ngo uyikureho.

    Nkeneye karuvati yo gukoresha kole ya polyurethane ikora vuba mu mbaho. Ese TMEDA ni amahitamo meza?

    Yego, ongeramo 0.3–0.8% by'uburemere bwa resin kugira ngo ubone igihe cyo gufungura iminota 5–10.

    Ese TMEDA ishobora gukoreshwa muri elastomer za polyurethane ku byuma bizunguruka?

    Yego, ariko kubera ko ihindagurika cyane, tekereza gukoresha amine ikora nka MOFAN 50 mu gukoresha ubushyuhe bwinshi.

    Uburyo bwo gukaraba ifuro ryanjye rikomeye ryo gusukamo ifuro buragoye cyane. Ese TMEDA ishobora kumfasha?

    TMEDA ikora cyane cyane ku gushyushya, ntabwo ari ugupima imiterere y'ingufu; ahubwo hindura ukoreshe katalyst ya trimer nka TMR-30.

    Nigute nabika TMEDA kugira ngo ikomeze gukora mu gihe kirenga amezi 6?

    Bika mu gikoresho gifunze neza kirimo azote kure y'ubushuhe na aside; ni hygroscopic.

    Ese TMEDA ishobora gusimbura PMDETA (MOFAN 5) mu gukaraba epoxy?

    Igice kimwe; TMEDA yihuta ariko itanga igihe gito cyo kumara inkono. Koresha TMEDA mu kuvura ubushyuhe buke, PMDETA mu kuvura ubushyuhe bw'icyumba.
