    Cov Lus Nug Feem Ntau

    Kuv tsim cov tshuaj polyurethane uas tsis muaj ntxhiab tsw qab hauv dej. DPA pab tau li cas?

    DPA yog ib qho tshuaj amine uas tsis muaj ntxhiab tsw, uas txo cov ntxhiab tsw ntawm amine thaum lub sijhawm siv thiab tom qab tsim cov zaj duab xis.

    Kuv cov polyurethane elastomer tsis muaj zog tear. DPA puas tuaj yeem txhim kho nws?

    Yog lawm, nws cov qauv diisopropanolamine tuaj yeem ua rau kom muaj qhov sib txuas ntawm qhov sib txuas thiab kev tiv thaiv kev tsim kua muag thaum siv ntawm 0.2–0.5 phr.

    Cov tshuaj DPA uas siv rau hauv cov polyurethane sealant kom lo rau cov pob zeb ua vaj tse zoo dua yog pes tsawg?

    0.3–0.6 phr; nws ua kom cov dej ntub thiab cov tshuaj sib txuas rau cov pob zeb hauv av zoo dua.

    Puas siv tau DPA ua tus co-catalyst hauv polyurethane spray foams kom txo tau cov ntxhiab tsw?

    Yog, nws pab txo qhov kev hloov pauv ntawm amine tag nrho; feem ntau sib xyaw nrog MOFAN 33LV.

    Kuv cov nplaum polyurethane rau PVC tsis tiv taus cua sov. Yuav ua li cas kom zoo dua?

    Ntxiv DPA (0.4 phr) kom nce qhov ceev ntawm kev sib txuas, ua kom qhov kub ntawm qhov cua sov nce siab.

    DPA puas sib xws nrog cov txheej txheem kho dej noo?

    Nws siv tau, tab sis vim nws muaj OH pawg, nws yuav ua rau isocyanate tshwm sim. Siv rau hauv ob lub tshuab xwb.

    DPA piv rau triethanolamine (TEOA) li cas ua tus crosslinker?

    DPA yog ib qho catalyst zoo dua thiab milder crosslinker; TEOA feem ntau yog ib qho crosslinker nrog cov catalytic ua haujlwm tsis muaj zog.

    Kuv cov ua npuas polyurethane rau kev ntim khoom qeeb qeeb rov qab los tom qab nias. DPA puas kho tau qhov no?

    Yog, nce DPA mus rau 0.2–0.3 phr los txhim kho kev tsim cov network elastic.

    Puas siv tau DPA hauv cov txheej txheem epoxy los txhim kho kev ywj pheej?

    Yog, ua ib qho kev hloov kho nws tuaj yeem txo qhov brittleness yam tsis tau qeeb qhov kev kho.

    Lub txee lub neej ntawm cov polyol sib xyaw uas muaj DPA yog dab tsi?

    Yam tsawg kawg yog 6 lub hlis thaum khaws cia rau hauv lub thawv qhuav thiab kaw.
