    Incazelo

    I-MOFAN A1 iyi-amine yesithathu enethonya elinamandla ekusabeleni kwe-urea (water-isocyanate) kuma-foam e-polyurethane aguquguqukayo futhi aqinile. Iqukethe i-70% bis(2-Dimethylaminoethyl) ether exutshwe ne-30% dipropylene glycol.

    Isicelo

    I-MOFAN A1 catalyst ingasetshenziswa kuzo zonke izinhlobo zefomula ze-foam. Umphumela onamandla we-catalytic ekusabeleni kokuvunguza ungalinganiswa ngokungeza i-catalyst enamandla ye-gelling. Uma ukukhishwa kwama-amine kuyinkinga, kunezinye izindlela zokukhishwa okuphansi ezitholakalayo ezisetshenziswa kakhulu ekugcineni.

    Ukuphatha
    Iseluleko ngokuphatha okuphephile: Unganambithi noma ugwinye. Gwema ukuthinta amehlo, isikhumba, nezingubo. Gwema ukuphefumula inkungu noma umhwamuko. Geza izandla ngemva kokuphatha.
    Iseluleko ngokuvikela umlilo nokuqhuma: Yonke imishini esetshenziswa lapho kuphathwa umkhiqizo kumele ibekwe phansi.

    Isitoreji
    Izidingo zezindawo zokugcina kanye nezitsha: Gcina isitsha sivaliwe kahle. Gcina kude nokushisa kanye nelangabi. Gcina kude nama-asidi.

    Imibuzo Evame Ukubuzwa

    Ngifuna i-catalyst elula ukuyiphatha ye-slabstock eqhubekayo. Kungani usebenzisa i-MOFAN A1 esikhundleni se-BDMAEE emsulwa?

    I-A1 ixutshwe ku-DPG, okwenza ingabi nokuguquguquka okukhulu, iphephe kakhulu ukuyiphatha, futhi kube lula ukuyilinganisa ngamaphampu ashibhile.

    Igwebu lami eliguquguqukayo livame ukusha ehlobo elishisayo. Ingabe i-A1 ingasiza?

    Yebo, ngoba incishisiwe, uthola umphumela ofanayo wokuvunguza nge-exotherm encane yendawo, okunciphisa ingozi yokusha.

    Iyini isilinganiso esijwayelekile sokuxuba ukuze kuthathelwe indawo i-BDMAEE emsulwa?

    I-1.43 kg ye-A1 (70%) inikeza i-BDMAEE esebenzayo efanayo ne-1 kg yomkhiqizo omsulwa.

    Ingabe i-A1 ingasetshenziswa ku-foam ebunjiwe kuma-matrasi ukuthuthukisa ukuphefumula?

    Yebo, isenzo sayo esinamandla sokushaywa sivula amaseli, sandisa ukuhamba komoya ngo-30–40%.

    Ifomu lami eliqinile elipheshulwa ngamanzi linokuqina okungekuhle. Ingabe i-A1 izolilungisa?

    Cha, igwebu eliqinile lidinga ijeli noma i-trimer catalyst enamandla. I-A1 izokwenza kube kubi kakhulu.

    Ngingayigcina kanjani i-A1 ebusika?

    I-A1 ingaqandisa ngaphansi kuka-10°C; gcina endaweni yokugcina impahla efudumele noma ufudumale isigubhu ku-20°C ngaphambi kokusebenzisa.

    Ingabe i-A1 iyahambisana nama-neutralizer e-amine kuma-polyurethane coating?

    Yebo, kodwa ukuhlola ukuhambisana njenge-DPG kungathinta ubulukhuni befilimu.

    I-foam yami ye-slabstock ine-density gradient (ephezulu ilula, engezansi inzima). Ngingakulungisa kanjani?

    Khulisa i-A1 ngo-0.02–0.04 phr ukuze ukhuthaze ukukhuphuka okusheshayo kanye nobuningi obufanayo.

    Ingabe i-A1 ingasetshenziswa ekwakhiweni kwe-foam okunamandla okuqina?

    Yebo, kodwa ngesilinganiso esiphansi (0.05–0.1 phr) ukuze kugwenywe ukukhukhumala ngokweqile kanye nokuwa kwamaseli.

    Iyiphi i-co-catalyst engcono kakhulu ye-A1 ekwakhiweni okungabizi kakhulu?

    Isixazululo se-MOFAN 33LV (TEDA) sinikeza ibhalansi engcono kakhulu yezindleko/yokusebenza.
