    Kufotokozera

    MOFAN B2010 ndi chothandizira chamadzimadzi chachikasu cha organic bismuth. Chingathe kulowa m'malo mwa dibutyltin dilaurate m'mafakitale ena a polyurethane, monga PU leather resin, polyurethane elastomer, polyurethane prepolymer, ndi PU track. Chimasungunuka mosavuta m'machitidwe osiyanasiyana a polyurethane okhala ndi zosungunulira.
    ● Ikhoza kulimbikitsa reaction ya -NCO-OH ndikupewa reaction ya mbali ya gulu la NCO. Ikhoza kuchepetsa mphamvu ya reaction ya madzi ndi gulu la -NCO (makamaka mu dongosolo la sitepe imodzi, ikhoza kuchepetsa kupanga kwa CO2).
    ● Ma asidi achilengedwe monga oleic acid (kapena kuphatikiza ndi organic bismuth catalyst) amatha kulimbikitsa momwe gulu la amine-NCO (lachiwiri) limagwirira ntchito.
    ● Mu kufalikira kwa PU pogwiritsa ntchito madzi, zimathandiza kuchepetsa momwe madzi ndi gulu la NCO zimagwirira ntchito.
    ●Mu dongosolo la chinthu chimodzi, ma amine omwe amatetezedwa ndi madzi amatulutsidwa kuti achepetse zotsatira zoyipa pakati pa madzi ndi magulu a NCO.

    Kugwiritsa ntchito

    MOFAN B2010 imagwiritsidwa ntchito pa utomoni wa chikopa cha PU, polyurethane elastomer, polyurethane prepolymer, ndi PU track etc.

    Kusamalira ndi kusunga

    Malangizo okhudza kugwiritsa ntchito bwino:Gwirani motsatira malamulo a Mulungu okhudza ukhondo ndi chitetezo m'mafakitale. Pewani kukhudza khungu ndi maso. Perekani mpweya wokwanira komanso/kapena utsi wokwanira m'zipinda zogwirira ntchito. Azimayi oyembekezera ndi oyamwitsa sangakumane ndi mankhwalawa. Ganizirani malamulo a dziko lonse.

    Njira Zoyezera Ukhondo:Kusuta fodya, kudya ndi kumwa kuyenera kuletsedwa pamalo opaka mankhwala. Sambani m'manja musanayambe nthawi yopuma komanso kumapeto kwa tsiku logwira ntchito.

    Zofunikira pa malo osungiramo zinthu ndi zotengera:Sungani kutali ndi kutentha ndi magwero oyatsira moto. Tetezani ku kuwala. Sungani chidebecho motseka bwino pamalo ouma komanso opumira bwino.

    Malangizo okhudza chitetezo ku moto ndi kuphulika:Sungani kutali ndi zinthu zomwe zimayambitsa moto. Osasuta fodya.

    Malangizo okhudza kusungira zinthu zambiri:Sizigwirizana ndi zinthu zophera oxidants.

    FAQ

    Ndikufuna chothandizira cha polyurethane chopanda poizoni, chopanda lead komanso chopanda zitini. Kodi B2010 ndi njira ina yabwino?

    Inde, zinthu zoyambitsa bismuth zachilengedwe ndi zotetezeka, zopanda poizoni, ndipo zimapereka kukana kwabwino kwa hydrolysis; ndizoyenera kugwiritsidwa ntchito pokhudzana ndi chakudya komanso kuchipatala.

    Elastomer yanga ya polyurethane yolumikizira madzi akumwa siifuna zitsulo zolemera. Kodi mlingo wa B2010 umagwira ntchito bwanji?

    0.05–0.2 phr; imapereka ntchito yofanana ndi ya DBTDL koma ndi poizoni wochepa kwambiri.

    Kodi chothandizira cha bismuth chimathamanga ngati chothandizira cha tin mu zokutira za polyurethane?

    Pang'onopang'ono; mutha kuwonjezera mpaka 0.3–0.5 phr kapena kuphatikiza ndi zinc catalyst (monga, MOFAN Z1910) kuti mugwirizane.

    Chotsekera changa cha zigawo ziwiri chimakhala ndi nthawi yochepa yokhala ndi DBTDL. Kodi B2010 ingachiwonjezere?

    Inde, zinthu zoyambitsa matenda a bismuth nthawi zambiri zimakhala ndi moyo wautali wa 30-50% pamene zimasunga mphamvu yochira.

    Kodi MOFAN B2010 ingagwiritsidwe ntchito mu thovu lolimba la polyurethane poteteza zida zamagetsi?

    Inde, koma si chothandizira kupukuta; phatikizani ndi zothandizira kupukuta za potaziyamu kuti mupange thovu loletsa moto.

    Kodi bismuth catalyst imayambitsa kusintha kwa mtundu mu zophimba za PU zowonekera?

    Ayi, mankhwala a bismuth samayambitsa chikasu, mosiyana ndi ma catalyst ambiri a tin.

    Kodi kuchuluka kwa chitsulo komwe kumachitika mu B2010 ndi kotani?

    Pafupifupi 20–22% ya bismuth; ndi madzi otchedwa carboxylate.

    Chomatira changa cha polyurethane chopangira chakudya sichiyenera kusunthidwa kwambiri. Kodi B2010 yavomerezedwa?

    Inde, ma bismuth catalysts amaloledwa m'malamulo ambiri okhudzana ndi chakudya omwe ali ndi malire ochepa osamukira.

    Kodi B2010 imafanana bwanji ndi zinc kapena zirconium catalysts?

    Bismuth imagwira ntchito kwambiri kuposa zinc koma sigwira ntchito kwambiri kuposa tin; imapereka nthawi yotseguka komanso liwiro lochira.

    Kodi nthawi yosungiramo zinthu ya B2010 ndi yotani?

    Miyezi 12 m'chidebe chotsekedwa komanso chouma; sichimakhudzidwa kwambiri ndi chinyezi kuposa zinthu zoyambitsa chidebe.
