    Tsananguro

    MOFAN B2010 imhando ye bismuth ine ruvara rweyero uye inonyunguduka. Inogona kutsiva dibutyltin dilaurate mune mamwe maindasitiri e polyurethane, akadai sePU dehwe resin, polyurethane elastomer, polyurethane prepolymer, uye PU track. Inonyungudika nyore nyore mumhando dzakasiyana dze polyurethane dzine solvent-based solvent.
    ● Inogona kukurudzira reaction ye -NCO-OH uye kudzivirira reaction yedivi reNCO group. Inogona kuderedza mhedzisiro ye reaction yemvura uye ye -NCO group (kunyanya mu one-step system, inogona kuderedza kugadzirwa kweCO2).
    ● Maasidhi eorganic akadai se oleic acid (kana kuti pamwe chete ne organic bismuth catalyst) anogona kukurudzira kuita kweboka re (secondary) re amine-NCO.
    ● Mukupararira kwePU kwakavakirwa mumvura, zvinobatsira kuderedza mativi emvura neboka reNCO.
    ●Mune imwe chete ine chikamu chimwe chete, maamine akadzivirirwa nemvura anoburitswa kuderedza mafambiro ekunze pakati pemvura nemapoka eNCO.

    Kushandiswa

    MOFAN B2010 inoshandiswa paPU dehwe resin, polyurethane elastomer, polyurethane prepolymer, uye PU track nezvimwewo.

    Mibvunzo Inowanzo bvunzwa

    Ndinoda chinhu chinobatsira chepolyurethane chisina chepfu, chisina mutobvu uye chisina tin. B2010 ndiyo imwe nzira yakanaka here?

    Ehe, organic bismuth catalysts dzakachengeteka, hadzina chepfu, uye dzinopa simba rakanaka rekudzivirira hydrolysis; dzakanakira kushandiswa mukudya uye mukurapa.

    Elastomer yangu yepolyurethane yekushandisa mvura inonwiwa haidi simbi dzinorema. Chipimo cheB2010 chinoshanda sei?

    0.05–0.2 phr; inoita basa rakafanana neDBTDL asi ine chepfu shoma.

    Ko bismuth catalyst inokurumidza sei tin catalyst mu polyurethane coatings?

    Zvishoma nezvishoma; unogona kuwedzera kusvika pa 0.3–0.5 phr kana kusanganisa ne zinc catalyst (semuenzaniso, MOFAN Z1910) kuti pave nekubatana.

    Chivharo changu chine zvikamu zviviri chinogara kwenguva pfupi neDBTDL. B2010 inogona kuchiwedzera simba rayo here?

    Ehe, bismuth catalysts inowanzoita kuti mvura igare kwenguva refu ne30-50% uku ichiramba ichikurumidza kupora.

    MOFAN B2010 inogona kushandiswa mu polyurethane rigid foam here kuti ivhare zvishandiso?

    Ehe, asi haisi trimer catalyst; shandisa pamwe chete ne potassium trimer catalysts kuti uwane furo rinodzivirira moto.

    Ko bismuth catalyst inokonzera kuchinja kweruvara muPU coatings yakajeka here?

    Kwete, macompound ebismuth haakonzeri kutsvuka kwebvudzi, kusiyana nemamwe matin catalysts.

    Chii chinowanzo shandiswa musimbi yeB2010?

    Inenge 20–22% yebismuth; imhando ye liquid carboxylate.

    Chinonamira changu chepolyurethane chekurongedza chikafu hachidi kutamiswa zvakanyanya. B2010 inotenderwa here?

    Ehe, bismuth catalysts inotenderwa mumitemo yakawanda yekubata chikafu ine miganhu yakaderera yekutama.

    B2010 inoenzaniswa sei ne zinc kana zirconium catalysts?

    Bismuth inoshanda zvakanyanya kupfuura zinc asi haishande zvakanyanya kupfuura tin; inopa nguva yakakwana yekuvhura uye kukurumidza kuporesa.

    Nguva yekushanda kweB2010 ndeyei?

    Mwedzi gumi nemiviri mumudziyo wakavharwa, wakaoma; haunyanyi kubatwa nehunyoro pane zvinokonzeresa simbi.
