    Ibisobanuro

    MOFAN B2010 ni catalyst y'umuhondo w'umwimerere wa bismuth. Ishobora gusimbura dibutyltin dilaurate mu nganda zimwe na zimwe za polyurethane, nka PU leather resin, polyurethane elastomer, polyurethane prepolymer, na PU track. Irashongesha byoroshye mu buryo butandukanye bwa polyurethane bushingiye ku bismuth.
    ● Bishobora guteza imbere reaction ya -NCO-OH no kwirinda reaction y’itsinda rya NCO. Bishobora kugabanya ingaruka z’amazi n’itsinda rya -NCO (cyane cyane muri sisitemu imwe, bishobora kugabanya ikorwa rya CO2).
    ● Aside organic nka aside oleic (cyangwa ivanze na bismuth catalyst organic) ishobora guteza imbere uburyo itsinda rya amine-NCO (rya kabiri) rikora.
    ● Mu gukwirakwira kwa PU bishingiye ku mazi, bifasha kugabanya ingaruka z’amazi n’itsinda rya NCO.
    ●Mu buryo bw'igice kimwe, amine zirinzwe n'amazi zirarekurwa kugira ngo bigabanye ingaruka mbi hagati y'amazi n'amatsinda ya NCO.

    Porogaramu

    MOFAN B2010 ikoreshwa mu gukora resin y'uruhu ya PU, elastomer ya polyurethane, prepolymer ya polyurethane, na PU track n'ibindi.

    Gufata no kubika

    Inama ku bijyanye no gucunga neza:Gufata ibintu hakurikijwe isuku n'umutekano by'inganda. Irinde ko byagera ku ruhu no mu maso. Tanga umwuka uhagije cyangwa imyotsi ihagije mu byumba by'akazi. Abagore batwite n'abonsa bashobora kutagerwaho n'icyo gicuruzwa. Hitamo amabwiriza y'igihugu.

    Ibipimo by'isuku:Kunywa itabi, kurya no kunywa bigomba kubujijwe aho umuntu asuzumirwa. Karaba intoki mbere yo kuruhuka no mu mpera z'umunsi w'akazi.

    Ibibazo Bikunze Kubazwa

    Nkeneye kaseti idafite uburozi, idafite lisansi kandi idafite amabati yo gukoresha polyurethane. Ese B2010 ni ubundi buryo bwiza?

    Yego, katalogeri za bismuth zikomoka ku bimera ni nziza, ntizihumanya, kandi zitanga ubudahangarwa bwiza bwo kwangirika kw'amazi; ni nziza cyane mu gukoresha mu kurya no mu buvuzi.

    Elastomer yanjye ya polyurethane yo gukoresha amazi yo kunywa ntabwo isaba ibyuma biremereye. Ni iyihe ngano ya B2010 ikora?

    0.05–0.2 phr; itanga imikorere isa na DBTDL ariko ifite uburozi buke cyane.

    Ese katalyst ya bismuth yihuta nk'ikatalyst ya tin mu irangi rya polyurethane?

    Bigenda buhoro gato; ushobora kongera kugeza kuri 0.3–0.5 phr cyangwa ukavanga na catalyst ya zinc (urugero, MOFAN Z1910) kugira ngo bihuze.

    Ifu yanjye ifite ibice bibiri iramba igihe gito hamwe na DBTDL. Ese B2010 ishobora kongera igihe cyayo?

    Yego, bismuth catalysts ubusanzwe zimara igihe kirekire hagati ya 30–50% mu gihe zigumana umuvuduko wo gukira burundu.

    Ese MOFAN B2010 ishobora gukoreshwa mu ifuro rikomeye rya polyurethane mu gukingira ibikoresho by'ikoranabuhanga?

    Yego, ariko si katalyst yo gukata; shyira hamwe na katalyst yo gukata potasiyumu kugira ngo ubone ifuro ritangiza umuriro.

    Ese bismuth catalyst itera ibara ry'uruhu mu bipfuko bya PU bisobanutse neza?

    Oya, ibinyabutabire bya bismuth ntibitera umuhondo, bitandukanye n'ibindi binyabutabire byinshi bya tin.

    Ubusanzwe ingano y'icyuma cya B2010 ni iyihe?

    Bismuth iri hagati ya 20–22%; ni karuboksilate y'amazi.

    Kole yanjye ya polyurethane yo gupfunyika ibiryo ikeneye kwimuka gake. Ese B2010 yemewe?

    Yego, bismuth catalysts yemerewe mu mategeko menshi agenga imikorere y'ibiryo hamwe n'imipaka mike yihariye yo kwimuka.

    Ni gute B2010 igereranywa na zinc cyangwa zirconium catalysts?

    Bismuth ikora cyane kurusha zinc ariko ntikora cyane kurusha tin; itanga uburinganire bwiza mu gihe cyo gufungura no kwihuta mu kuvura.

    Igihe cyo kubika B2010 ni ikihe?

    Amezi 12 mu gikoresho gifunze kandi cyumye; ntabwo cyorohera cyane ubushuhe nk'ibikoreshwa mu gukaraba ibiti.
