    Inkcazo

    I-MOFAN B2010 yi-catalyst ye-organic bismuth engamanzi emthubi. Ingathatha indawo ye-dibutyltin dilaurate kwamanye amashishini e-polyurethane, njenge-PU leather resin, i-polyurethane elastomer, i-polyurethane prepolymer, kunye ne-PU track. Inyibilika lula kwiinkqubo ezahlukeneyo ze-polyurethane ezisekwe kwi-solvent.
    ● Ingakhuthaza impendulo ye--NCO-OH kwaye iphephe impendulo esecaleni yeqela le-NCO. Inganciphisa isiphumo samanzi kunye nempendulo yeqela le--NCO (ingakumbi kwinkqubo yenyathelo elinye, inokunciphisa ukuveliswa kwe-CO2).
    ● Ii-asidi ze-organic ezifana ne-oleic acid (okanye zidityaniswe ne-organic bismuth catalyst) zinokukhuthaza ukusabela kweqela le-amine-NCO (lesibini).
    ● Kwi-PU dispersion esekwe emanzini, inceda ukunciphisa impendulo ecaleni kwamanzi kunye neqela le-NCO.
    ●Kwinkqubo enecandelo elinye, ii-amine ezikhuselwe ngamanzi ziyakhutshwa ukunciphisa iimpembelelo ezimbi phakathi kwamanzi kunye namaqela e-NCO.

    Isicelo

    I-MOFAN B2010 isetyenziselwa i-PU leather resin, i-polyurethane elastomer, i-polyurethane prepolymer, kunye ne-PU track njl.

    Ukuphatha kunye nokugcina

    Ingcebiso malunga nokuphathwa ngokukhuselekileyo:Phatha ngokuhambelana nococeko nokhuseleko lwemizi-mveliso. Kuphephe ukudibana nolusu namehlo. Nika umoya owaneleyo kunye/okanye umsi wokukhupha umoya kumagumbi okusebenzela. Abafazi abakhulelweyo nabancancisayo abanako ukuchatshazelwa yimveliso. Cinga ngommiselo wesizwe.

    Amanyathelo oCoceko:Ukutshaya, ukutya nokusela akufanelekanga kwindawo efakelwe kuyo. Hlamba izandla ngaphambi kwekhefu nasekupheleni kosuku lomsebenzi.

    Iimfuneko zeendawo zokugcina izinto kunye nezikhongozeli:Gcina kude nobushushu kunye nemithombo yokutsha. Khusela ekukhanyeni. Gcina isitya sivaliwe kakuhle kwindawo eyomileyo nengena umoya.

    Ingcebiso malunga nokukhusela umlilo kunye nokuqhuma:Gcina kude nemithombo yokutshaya. Akuvumelekanga ukutshaya.

    Ingcebiso malunga nokugcinwa kwezinto eziqhelekileyo:Ayihambelani nee-oxidizing agents.

    FAQ

    Ndifuna i-catalyst engenatyhefu, engenalo ilothe kwaye engenazinti kwi-polyurethane. Ngaba i-B2010 yindlela elungileyo?

    Ewe, ii-organic bismuth catalysts zikhuselekile, azinatyhefu, kwaye zibonelela ngokumelana okuhle kwe-hydrolysis; zilungele ukusetyenziswa kokutya kunye nokusetyenziswa kwezonyango.

    I-polyurethane elastomer yam yokunxibelelana namanzi okusela ayifuni zinyithi zinzima. Yeyiphi idosi ye-B2010 esebenzayo?

    0.05–0.2 phr; inika umsebenzi ofanayo neDBTDL kodwa inetyhefu ephantsi kakhulu.

    Ingaba i-bismuth catalyst ikhawuleza njenge-tin catalyst kwiingubo ze-polyurethane?

    Icotha kancinci; ungayandisa ukuya kwi-0.3–0.5 phr okanye udibanise ne-zinc catalyst (umz., MOFAN Z1910) ukuze kubekho intsebenziswano.

    I-sealant yam enamacandelo amabini inobomi obufutshane xa isetyenziswa yi-DBTDL. Ngaba i-B2010 ingayindisa?

    Ewe, ii-bismuth catalysts zihlala zinika ubomi obude obuyi-30-50% ngelixa zigcina isantya sokugqibela sokuphiliswa.

    Ngaba i-MOFAN B2010 ingasetyenziswa kwi-polyurethane rigid foam ukuze ifakelwe izixhobo?

    Ewe, kodwa ayisiyonto yokulungisa i-trimer; dibanisa ne-potassium trimer catalysts ukuze ufumane i-foam ethintela umlilo.

    Ngaba i-bismuth catalyst ibangela ukutshintsha kombala kwiingubo ze-PU ezicacileyo?

    Hayi, iikhompawundi zebismuth azibangeli tyheli, ngokungafaniyo nezinye iikhatalyst ezininzi zetin.

    Ingakanani i-metal content eqhelekileyo ye-B2010?

    Malunga ne-20–22% ye-bismuth; yi-carboxylate engamanzi.

    Isincamathelisi sam se-polyurethane sokupakisha ukutya asidingi kutshintshwa kakhulu. Ngaba i-B2010 iyavunywa?

    Ewe, ii-bismuth catalysts zivumelekile kwimigaqo emininzi yokunxibelelana kokutya enemida ethile yokufuduka.

    I-B2010 ithelekiswa njani nee-catalysts ze-zinc okanye ze-zirconium?

    I-Bismuth isebenza ngakumbi kune-zinc kodwa ayisebenzi kangako kune-tin; ibonelela ngokulinganisela okuhle kwexesha lokuvula kunye nesantya sokuphiliswa.

    Ingakanani ixesha lokuphelelwa kwe-B2010?

    Ihlala iinyanga ezili-12 kwisikhongozeli esivaliweyo nesomileyo; ayichukumisi kangako kumswakama kunee-catalysts zetin.
