    Incazelo

    I-MOFAN B2010 iyi-catalyst ye-bismuth ephuzi ewuketshezi. Ingathatha indawo ye-dibutyltin dilaurate kwezinye izimboni ze-polyurethane, njenge-PU leather resin, i-polyurethane elastomer, i-polyurethane prepolymer, kanye ne-PU track. Incibilika kalula ezinhlelweni ezahlukene ze-polyurethane ezisekelwe ku-solvent.
    ● Kungakhuthaza ukusabela kwe--NCO-OH futhi kugweme ukusabela okungekuhle kweqembu le-NCO. Kunganciphisa umphumela wamanzi kanye nokusabela kweqembu le--NCO (ikakhulukazi ohlelweni lwesinyathelo esisodwa, kunganciphisa ukukhiqizwa kwe-CO2).
    ● Ama-asidi e-organic njenge-oleic acid (noma ehlanganiswe ne-organic bismuth catalyst) angakhuthaza ukusabela kweqembu (lesibili) le-amine-NCO.
    ● Ekusabalaleni kwe-PU okusekelwe emanzini, kusiza ukunciphisa ukusabela okuseceleni kwamanzi kanye neqembu le-NCO.
    ●Esimisweni esinengxenye eyodwa, ama-amine avikelwe ngamanzi ayakhishwa ukuze kuncishiswe ukusabela okungekuhle phakathi kwamanzi namaqembu e-NCO.

    Isicelo

    Ukuphatha nokugcina

    Iseluleko ngokuphathwa okuphephile:Phatha ngokuhambisana nemithetho yezempilo kanye nokuphepha kwezimboni. Gwema ukuthintana nesikhumba namehlo. Nikeza ukushintshana komoya okwanele kanye/noma ukukhishwa komoya emakamelweni okusebenzela. Abesifazane abakhulelwe nabancelisayo kungenzeka bangadalulwa kumkhiqizo. Cabangela umthethonqubo kazwelonke.

    Izinyathelo Zokuhlanzeka:Ukubhema, ukudla nokuphuza kufanele kuvinjelwe endaweni yokufaka isicelo. Geza izandla ngaphambi kwekhefu kanye nasekupheleni kosuku lomsebenzi.

    Izidingo zezindawo zokugcina kanye nezitsha:Gcina kude nokushisa kanye nemithombo yokushisa. Vikela ekukhanyeni. Gcina isitsha sivaliwe kahle endaweni eyomile futhi enomoya omuhle.

    Iseluleko ngokuvikelwa emlilweni nasekuqhumeni:Gcina kude nemithombo yokushisa. Akuvunyelwe ukubhema.

    Iseluleko mayelana nokugcinwa okuvamile:Akuhambisani nama-oxidizing agents.

    Imibuzo Evame Ukubuzwa

    Ngidinga i-catalyst engenabo ubuthi, engenalo i-lead futhi engena-tin ye-polyurethane. Ingabe i-B2010 iyindlela engcono?

    Yebo, ama-catalyst e-bismuth e-organic aphephile, awanobuthi, futhi ahlinzeka ngokumelana okuhle kwe-hydrolysis; alungele ukusetshenziswa kokudla kanye nokwelashwa.

    I-polyurethane elastomer yami yokuxhumana namanzi aphuzwayo ayidingi izinsimbi ezisindayo. Yisiphi isilinganiso se-B2010 esisebenzayo?

    0.05–0.2 phr; inikeza umsebenzi ofanayo ne-DBTDL kodwa inobuthi obuphansi kakhulu.

    Ingabe i-catalyst ye-bismuth ishesha njenge-catalyst ye-tin ezimbozweni ze-polyurethane?

    Kancane kancane; ungandisa ube ngu-0.3–0.5 phr noma uhlanganise ne-zinc catalyst (isb., MOFAN Z1910) ukuze kuhlanganiswe.

    I-sealant yami enezingxenye ezimbili ihlala isikhathi esifushane uma isetshenziswa yi-DBTDL. Ingabe i-B2010 ingayandisa?

    Yebo, ama-catalyst e-bismuth ngokuvamile anika impilo ende engu-30-50% ngenkathi egcina isivinini sokugcina sokwelapha.

    Ingabe i-MOFAN B2010 ingasetshenziswa ku-polyurethane rigid foam ukuze kufakwe izinto ezivikela ugesi?

    Yebo, kodwa akuyona into ebangela ukuqhuma kwe-trimer; hlanganisa ne-potassium trimer catalysts ukuze uthole i-foam evimbela umlilo.

    Ingabe i-bismuth catalyst ibangela ukushintsha kombala ezimbozweni ze-PU ezicacile?

    Cha, ama-compound e-bismuth awabangeli ukuphuzi, ngokungafani nama-catalyst amaningi e-tin.

    Kungakanani okuqukethwe kwensimbi okuvamile kwe-B2010?

    Cishe i-bismuth engu-20–22%; iyi-carboxylate ewuketshezi.

    Isinamathelisi sami se-polyurethane sokupakisha ukudla sidinga ukufuduka okuncane. Ingabe i-B2010 iyavunyelwa?

    Yebo, ama-catalyst e-bismuth avunyelwe emithethweni eminingi yokuxhumana kokudla enemikhawulo ephansi yokufuduka.

    I-B2010 iqhathaniswa kanjani nama-catalyst e-zinc noma e-zirconium?

    I-Bismuth isebenza kakhulu kune-zinc kodwa ayisebenzi kakhulu kune-tin; inikeza ibhalansi enhle yesikhathi sokuvula kanye nesivinini sokwelapha.

    Ingakanani isikhathi sokuphelelwa yisikhathi se-B2010?

    Izinyanga ezingu-12 esitsheni esivaliwe, esomile; ayizweli kakhulu kumswakama kunezikhuthazi zethini.
