    Kufotokozera

    MOFAN DBU ndi amine yachitatu yomwe imalimbikitsa kwambiri urethane (polyol-isocyanate) reaction mu thovu losinthasintha pang'ono, komanso mu ntchito zophimba, zomatira, zotsekera, ndi elastomer. Imakhala ndi mphamvu yamphamvu kwambiri yopangira gelation, imapereka fungo lochepa ndipo imagwiritsidwa ntchito mu mapangidwe okhala ndi aliphatic isocyanates chifukwa amafunikira ma catalyst amphamvu kwambiri chifukwa sagwira ntchito kwambiri kuposa aromatic isocyanates.

    FAQ

    Ndikufuna chothandizira champhamvu kwambiri kuti CO2 ikhazikike mu cyclic carbonates. Kodi DBU ndi yoyenera?

    Inde, DBU ndi imodzi mwa maziko amphamvu kwambiri omwe si a nucleophilic, abwino kwambiri poyambitsa CO2 ndi epoxides.

    Elastomer yanga ya polyurethane ili ndi kukhazikika koipa kwa hydrolytic. Kodi DBU ingathandize?

    Ayi, DBU ingathandize kuti hydrolysis ichitike; gwiritsani ntchito tin kapena zinc catalyst m'malo mwake.

    Kodi DBU ingagwiritsidwe ntchito bwanji ngati chothandizira kuyeretsa thovu la PIR logwira ntchito bwino?

    Onjezani 0.3–0.8 phr DBU pamodzi ndi potaziyamu catalyst kuti mupeze kuchuluka kwa isocyanurate (>30%).

    Kodi DBU imasungunuka mu polyols wamba wa polyether?

    Inde, imasakanizidwa ndi ma polyol ambiri ndipo sifunikira kuisamalira mwapadera.

    Dongosolo langa la epoxy-amine lili ndi nthawi yayitali kwambiri yochira kutentha kwa mlengalenga. Kodi DBU ingalifulumizitse?

    Inde, DBU ndi chida champhamvu chofulumizitsa; gwiritsani ntchito 0.1–0.5 phr kuti muchepetse kwambiri moyo wa mphika ndi nthawi yochira.

    Kodi DBU imayambitsa kusintha kwa mtundu wa polyurethanes yowonekera?

    Zingayambitse chikasu pakapita nthawi chifukwa cha kulimba kwake; pewani kugwiritsa ntchito ngati kuwala kwa dzuwa.

    Kodi DBU ingagwiritsidwe ntchito poyambitsa zomwe isocyanate imachita ndi mowa m'malo otentha kwambiri?

    Inde, imakhalabe yogwira ntchito ngakhale pansi pa 0°C, zomwe zimapangitsa kuti ikhale yothandiza pamakina a PU a m'nyengo yozizira.

    Kodi DBU imagwiritsidwa ntchito bwanji mu dongosolo lopangira polyurethane pazinthu zazikulu?

    0.05–0.15 phr kuti mupewe exotherm yambiri; nthawi zonse sakanizani ndi gel catalyst kuti mukhale ndi thanzi labwino.

    Kasitomala wanga amafuna chothandizira chomwe chilibe tin kapena mercury. Kodi DBU ndi njira ina yabwino?

    Inde, DBU ndi chothandizira cholimba chopanda zitsulo, choyenera kugwiritsidwa ntchito kuchipatala komanso pokhudzana ndi chakudya mutachotsa bwino.

    Kodi ndiyenera kuchita bwanji ndi DBU kuti ndipewe kuyabwa pakhungu?

    Gwiritsani ntchito magolovesi ndi magalasi oteteza maso; DBU imawononga zinthu. Chepetsani kutayikira kwa madzi ndi acetic acid wochepa.
