    Cov Lus Nug Feem Ntau

    Kuv xav tsim cov ua npuas ncauj PIR uas tsis yooj yim tawg. TMR-2 puas zoo dua TMR-30?

    Yog, TMR-2 (ntses quaternary ammonium) muab qhov qis dua friability thaum tseem muab kev ua haujlwm hluav taws zoo heev.

    Kuv cov ua npuas ncauj tawv tsis lo rau cov ntawv ci txhuas. TMR-2 yuav pab tau li cas?

    Nws qhov xwm txheej polar txhim kho kev nplaum rau cov hlau, txo qhov delamination.

    Qib kev siv TMR-2 li cas hauv PIR laminate tas mus li?

    0.4–1.2 phr nyob ntawm seb cov ntsiab lus ntawm lub tshuab trimer thiab qhov ceev ntawm kab xav tau.

    Puas siv tau TMR-2 ua ke nrog potassium octoate?

    Yog, lawv yog synergistic. Kev sib xyaw ntawm TMR-2 (0.5 phr) thiab potassium octoate (0.5 phr) muab trimerization zoo heev nrog qis brittleness.

    Kuv lub PIR ua npuas ncauj muaj cov qauv cell tsis sib npaug thiab tsis sib luag. Yuav ua li cas thiaj txhim kho tau?

    Ua kom TMR-2 nce me ntsis thiab txo cov tshuaj catalyst gel kom muaj peev xwm tswj tau cov npuas ntau dua.

    TMR-2 puas yaj tau hauv dej? Qhov ntawd cuam tshuam li cas rau kev ua cov txheej txheem?

    Yog, nws yaj tau hauv dej, tab sis tsis txhob muab dej tso rau hauv cov mis vim nws yuav ua rau isocyanate tawm tsam.

    TMR-2 puas ua rau xeb ntawm cov taub hau sib tov?

    Tsis yog, nws tsis muaj zog corrosive ntau dua li alkali hlau catalysts.

    Kuv lub vaj huam sib luag ua npuas dej tsis dhau qhov kev sim laus ntawm qhov kub thiab txias hauv chav (kev hloov pauv ntawm qhov loj >1%). TMR-2 puas kho tau nws?

    Yog lawm, cov ntsiab lus trimer siab dua los ntawm TMR-2 txhim kho qhov ruaj khov ntawm qhov ntev.

    Cov polyol sib xyaw uas muaj TMR-2 yuav siv tau ntev npaum li cas?

    3–6 lub hlis, tab sis tsis txhob khaws cov dej noo vim TMR-2 yog hygroscopic.

    Puas siv tau TMR-2 rau hauv cov kav dej rwb thaiv tsev uas muab nchuav rau hauv qhov chaw?

    Yog, nws muab kev ntws zoo thiab tsis yooj yim tawg, tsim nyog rau cov kav dej loj.
