    Kev piav qhia

    MOFAN B2010 yog cov kua daj organic bismuth catalyst. Nws tuaj yeem hloov dibutyltin dilaurate hauv qee qhov kev lag luam polyurethane, xws li PU tawv resin, polyurethane elastomer, polyurethane prepolymer, thiab PU track. Nws yooj yim yaj hauv ntau yam polyurethane systems uas muaj kuab tshuaj.
    ● Nws tuaj yeem txhawb nqa qhov kev ua haujlwm ntawm -NCO-OH thiab zam kev ua haujlwm ntawm pawg NCO. Nws tuaj yeem txo qhov cuam tshuam ntawm dej thiab pawg -NCO (tshwj xeeb tshaj yog hauv ib kauj ruam, nws tuaj yeem txo qhov kev tsim CO2).
    ● Cov organic acids xws li oleic acid (los yog ua ke nrog cov organic bismuth catalyst) tuaj yeem txhawb kev ua haujlwm ntawm (theem nrab) amine-NCO pawg.
    ● Hauv cov dej-raws li PU dispersion, nws pab txo cov tshuaj tiv thaiv sab ntawm dej thiab NCO pawg.
    ●Hauv ib lub tshuab uas muaj ib feem xwb, cov amines uas dej tiv thaiv raug tso tawm los txo cov kev cuam tshuam ntawm dej thiab NCO pawg.

    Daim Ntawv Thov

    MOFAN B2010 yog siv rau PU tawv resin, polyurethane elastomer, polyurethane prepolymer, thiab PU khiav thiab lwm yam.

    Kev tuav thiab kev cia khoom

    Cov lus qhia txog kev tuav pov hwm kom muaj kev nyab xeeb:Ua raws li kev cai huv thiab kev nyab xeeb hauv kev lag luam. Tsis txhob cia kov daim tawv nqaij thiab qhov muag. Muab cua thiab/lossis pa tawm kom txaus hauv chav ua haujlwm. Cov poj niam cev xeeb tub thiab cov poj niam pub niam mis yuav tsis raug cov khoom no. Xav txog txoj cai hauv tebchaws.

    Kev Ntsuas Kev Huv Si:Yuav tsum tsis pub haus luam yeeb, noj mov thiab haus dej hauv thaj chaw thov. Ntxuav tes ua ntej so thiab thaum kawg ntawm hnub ua haujlwm.

    Cov Kev Cai rau cov chaw cia khoom thiab cov thawv:Khaws cia kom deb ntawm qhov kub thiab qhov chaw uas ua rau hluav taws kub. Tiv thaiv kom tsis txhob muaj lub teeb. Khaws lub thawv kom kaw ruaj rau hauv qhov chaw qhuav thiab muaj cua nkag tau zoo.

    Cov lus qhia txog kev tiv thaiv hluav taws thiab kev tawg:Khaws cia kom deb ntawm cov chaw uas ua rau kub hnyiab. Tsis txhob haus luam yeeb.

    Cov lus qhia txog kev khaws cia rau sawv daws:Tsis sib haum nrog cov neeg sawv cev oxidizing.

    Cov Lus Nug Feem Ntau

    Kuv xav tau cov tshuaj catalyst uas tsis muaj tshuaj lom, tsis muaj lead thiab tsis muaj tin rau polyurethane. Puas yog B2010 yog lwm txoj hauv kev zoo?

    Yog, cov tshuaj catalysts organic bismuth muaj kev nyab xeeb, tsis muaj tshuaj lom, thiab muab kev tiv thaiv hydrolysis zoo; zoo tagnrho rau kev sib cuag zaub mov thiab kev siv kho mob.

    Kuv cov polyurethane elastomer rau kev sib cuag dej haus tsis xav tau cov hlau hnyav. B2010 ntau npaum li cas ua haujlwm?

    0.05–0.2 phr; nws muab cov haujlwm sib piv rau DBTDL tab sis muaj cov tshuaj lom tsawg dua.

    Puas yog bismuth catalyst ceev npaum li tin catalyst hauv polyurethane coatings?

    Qis me ntsis; koj tuaj yeem nce mus txog 0.3–0.5 phr lossis ua ke nrog zinc catalyst (piv txwv li, MOFAN Z1910) rau kev sib koom ua ke.

    Kuv cov sealant ob yam khoom muaj lub sijhawm luv luv nrog DBTDL. B2010 puas tuaj yeem ntev nws?

    Yog lawm, cov tshuaj bismuth feem ntau muab lub sijhawm ntev dua 30–50% thaum tswj qhov ceev ntawm kev kho zaum kawg.

    Puas siv tau MOFAN B2010 rau hauv polyurethane ua npuas ncauj rau kev rwb thaiv tsev khoom siv?

    Yog, tab sis nws tsis yog ib qho trimer catalyst; ua ke nrog potassium trimer catalysts rau cov ua npuas dej tua hluav taws.

    Puas yog bismuth catalyst ua rau muaj kev hloov pauv xim hauv cov txheej PU meej?

    Tsis yog, cov tshuaj bismuth tsis ua rau daj, tsis zoo li ntau cov catalysts tin.

    Cov ntsiab lus hlau ib txwm muaj ntawm B2010 yog dab tsi?

    Kwv yees li ntawm 20–22% bismuth; nws yog cov kua carboxylate.

    Kuv cov nplaum polyurethane rau kev ntim khoom noj yuav tsum tau hloov pauv tsawg. Puas tau pom zoo los ntawm B2010?
