    Cov Lus Nug Feem Ntau

    Kuv xav tau ib qho catalyst muaj zog heev rau CO2 fixation rau hauv cyclic carbonates. DBU puas tsim nyog?

    Yog lawm, DBU yog ib qho ntawm cov hauv paus tsis muaj zog tshaj plaws, zoo tagnrho rau kev ua kom CO2 thiab epoxides ua haujlwm.

    Kuv cov polyurethane elastomer tsis ruaj khov hydrolytic. DBU puas pab tau?

    Tsis yog, DBU yuav txhawb kev hydrolysis; siv cov tin lossis zinc catalyst hloov.

    Yuav siv DBU li cas los ua tus catalyst trimerization rau kev ua haujlwm siab PIR ua npuas ncauj?

    Ntxiv 0.3–0.8 phr DBU ua ke nrog cov tshuaj potassium kom ua tiav cov ntsiab lus isocyanurate siab heev (> 30%).

    DBU puas yaj tau hauv cov polyether polyols uas siv ntau?

    Yog, nws sib xyaw nrog feem ntau cov polyols thiab tsis xav tau kev tuav tshwj xeeb.

    Kuv lub epoxy-amine system muaj sijhawm kho ntev dhau ntawm qhov kub thiab txias. DBU puas tuaj yeem ua kom nws nrawm dua?

    Yog, DBU yog ib qho tshuaj ua kom nrawm dua; siv 0.1–0.5 phr kom txo tau lub neej ntawm cov tshuaj thiab lub sijhawm kho.

    Puas yog DBU ua rau muaj kev hloov pauv xim hauv cov polyurethanes ntshiab?

    Nws tuaj yeem ua rau daj dhau sijhawm vim nws lub hauv paus muaj zog; zam rau cov ntawv thov pom tseeb.

    Puas siv tau DBU los ua kom cov tshuaj tiv thaiv ntawm isocyanate nrog cov cawv hauv qhov chaw kub qis?

    Yog, nws tseem ua haujlwm txawm tias qis dua 0 ° C, ua rau nws muaj txiaj ntsig zoo rau cov txheej txheem PU qib caij ntuj no.

    Qib siv DBU li cas hauv polyurethane casting system rau cov khoom loj?

    0.05–0.15 phr kom tsis txhob muaj exotherm ntau dhau; ib txwm sib xyaw nrog cov tshuaj gel catalyst kom sib npaug.

    Kuv tus neeg siv khoom xav tau cov tshuaj catalyst uas tsis muaj tin lossis mercury. DBU puas yog lwm txoj hauv kev zoo?

    Yog, DBU yog ib qho catalyst muaj zog uas tsis muaj hlau, tsim nyog rau kev siv kho mob thiab kev sib cuag nrog zaub mov tom qab rho tawm kom raug.

    Kuv yuav tsum ua li cas thiaj li kov yeej DBU kom tsis txhob khaus tawv nqaij?

    Siv hnab looj tes thiab tsom iav; DBU yog corrosive. Tshem cov dej nchuav nrog dilute acetic acid.
