    katundu katundu & Features

    RFE polyisocyanate ndi njira yabwino kwambiri yolumikizira zomatira zochokera ku polyurethane, mphira wachilengedwe ndi mphira wa Synthesis. RFE polyisocyanate ndiyothandizanso pakuwongolera zomatira pazinthu zopangidwa ndi mphira. Itha kugwiritsidwa ntchito ngati crosslinker m'malo mwa Bayer's Desmodur RFE.

    Kugwiritsa ntchito

    Zomatira zamagulu awiri ziyenera kugwiritsidwa ntchito ndi nthawi yoyenera mutayika RFE.
    Kutalika kwa nthawi yogwira ntchito sikungokhudzana ndi zomatira za polima, komanso zigawo zina zofunikira (monga utomoni, Antioxygen, plasticizer, solvent, etc.
    Pafupi ndi nthawi yoyenera, nthawi zambiri maola angapo kapena tsiku limodzi logwira ntchito, zomatira zimakhala zovuta kugwira ntchito, ndipo kukhuthala kumakwera posachedwa.
    Pomaliza, imakhala yosasinthika odzola. Zomatira zamtundu wa 100, Hydroxyl polyurethane (mbiri ya Polyurethane pafupifupi 20%), RFE imachita 4-7. Chloroprene rabala (Rubber account pafupifupi 20%), RFE amachita 4-7.

    Kulongedza

    Phukusi: 0.75kg / botolo, mabotolo 20 okwana m'katoni imodzi, 180kg / mbiya, KAPENA malinga ndi pempho la makasitomala.

    Kusungirako

    - Sungani mu chidebe chosindikizidwa choyambirira cha Covestro.
    - Kutentha koyenera kosungirako: 10 - 30 °C.
    - Tetezani ku chinyezi, kutentha ndi zinthu zakunja.
    Zambiri: Pamayendedwe ndi kusungirako kutentha pang'ono,crystalline madipoziti akhoza kupanga.
    Izi zimasungunukanso kutentha. Themankhwala ndi tcheru kwambiri chinyezi ndi kuchita ndi madzi kupanga mpweyadioksidi ndi insoluble ureas.
    Zotengerazo ziyenera kusungidwa mwamphamvulosindikizidwa. Kulowetsedwa kwamadzi mwanjira iliyonse (zotengera zonyowa, zopanda madzizosungunulira, mpweya wonyowa) ayenera kupewedwa ngati mwinamwake mapangidwe mpweyadioksidi ikhoza kuyambitsa kuwonjezereka kwamphamvu kwamphamvu muzotengera.
    Kuwonekera kwa mpweya ndi/kapena kuwala kumawonjezera kusinthika koma izi sizimakhudzakatundu processing ambiri.
