    Inkcazo

    I-MOFAN DBU yi-tertiary amine ekhuthaza kakhulu i-urethane (polyol-isocyanate) reaction kwi-semi-flexible microcellular foam, nakwi-coating, adhesive, sealant kunye ne-elastomer applications. Ibonisa amandla amakhulu e-gelation, inika ivumba eliphantsi kwaye isetyenziswa kwi-formulations ezine-aliphatic isocyanates njengoko zifuna ii-catalysts ezinamandla kakhulu kuba azisebenzi kangako kune-aromatic isocyanates.

    Isicelo

    I-MOFAN DBU ikwifoam encinci eguquguqukayo kancinci, kwaye ikwizicelo zokugquma, zokuncamathisela, zokutywina kunye ne-elastomer

    Ukuphatha kunye nokugcina

    Amanyathelo okuzikhusela xa uphatha izinto ngokukhuselekileyo
    Qinisekisa ukuba umoya ungena kakuhle kwiindawo zokusebenzela nakwiindawo zokusebenzela. Phatha ngokuhambelana nococeko olufanelekileyo lwemizi-mveliso kunye neendlela zokhuseleko. Xa usebenzisa musa ukutya, ukusela okanye ukutshaya. Izandla kunye/okanye ubuso kufuneka buhlanjwe ngaphambi kokuba kuphunywe kwaye ekupheleni kweshifti.

    Ukhuseleko kumlilo nokuqhuma
    Thintela ukutshaja ngombane - imithombo yokutsha kufuneka igcinwe icocekile - izicimi-mlilo kufuneka zigcinwe zikufutshane.

    Imiqathango yokugcina ngokukhuselekileyo, kuquka naziphi na izinto ezingahambelaniyo
    Hlukanisa kwizinto ezifana nee-asidi kunye nezinto ezenza i-asidi.
    Ulwazi oluthe vetshe malunga neemeko zokugcina: Gcina isitya sivaliwe kakuhle kwindawo epholileyo, enomoya owaneleyo.

    FAQ

    Ndifuna isiseko esiqinileyo kakhulu sokuqiniswa kwe-CO2 kwii-carbonates ezijikelezayo. Ngaba i-DBU ifanelekile?

    Ewe, i-DBU yenye yezona ziseko zinamandla ezingezizo ze-nucleophilic, ezifanelekileyo ekusebenziseni i-CO2 kunye ne-epoxides.

    I-polyurethane elastomer yam ayina-hydrolytic stability. Ngaba i-DBU inokunceda?

    Hayi, i-DBU ingakhuthaza i-hydrolysis; sebenzisa i-tin okanye i-zinc catalyst endaweni yoko.

    Ingasetyenziswa njani i-DBU njengesixhobo sokulungisa i-trimerization kwi-PIR foam esebenza kakuhle?

    Yongeza i-0.3–0.8 phr DBU kunye ne-potassium catalyst ukuze ufumane umxholo ophezulu kakhulu we-isocyanurate (>30%).

    Ngaba i-DBU iyanyibilika kwi-polyols eziqhelekileyo ze-polyether?

    Ewe, iyaxutywa kwiipolyol ezininzi kwaye ayifuni ukuphathwa ngendlela ekhethekileyo.

    Inkqubo yam ye-epoxy-amine inexesha elide kakhulu lokunyanga xa ishushu. Ngaba i-DBU ingayikhawulezisa?

    Ewe, i-DBU yi-accelerator enamandla; sebenzisa i-0.1–0.5 phr ukunciphisa kakhulu ubomi bembiza kunye nexesha lokunyanga.

    Ngaba i-DBU ibangela ukutshintsha kombala kwi-polyurethanes ecacileyo?

    Ingabangela ukuba umbala ube tyheli ngokuhamba kwexesha ngenxa yokuba ilula kakhulu; kuphephe ukusetyenziswa kwayo xa ingabonakali kakuhle.

    Ngaba i-DBU ingasetyenziselwa ukushukumisa ukusabela kwe-isocyanate kunye nee-alcohols kwiindawo ezishushu kakhulu?

    Ewe, ihlala isebenza nangaphantsi kwe-0°C, nto leyo eyenza ukuba ibe luncedo kwiinkqubo ze-PU zasebusika.

    Ingakanani inqanaba eliqhelekileyo lokusetyenziswa kwe-DBU kwinkqubo yokuphosa i-polyurethane kwiindawo ezinkulu?

    0.05–0.15 phr ukuze kuthintelwe i-exotherm egqithisileyo; soloko udibanisa ne-gel catalyst ukuze kubekho ibhalansi.

    Umthengi wam ufuna i-catalyst engenazo i-tin okanye i-mercury. Ngaba i-DBU yindlela efanelekileyo yokukhetha?

    Ewe, i-DBU sisincedisi esiqinileyo esingenasinyithi, esifanelekileyo ukusetyenziswa kwezonyango kunye nokutya emva kokukhupha ngokufanelekileyo.

    Ndingayisebenzisa njani i-DBU ukuze ndiphephe ukurhawuzelelwa lusu?

    Sebenzisa iiglavu kunye neeglasi zeglasi; i-DBU iyakonakalisa. Nciphisa ukuchitheka kwenkunkuma nge-acetic acid enyibilikisiweyo.
