    RE ndi wothandizira kwambiri wolumikizirana, Amagwiritsidwa ntchito mu zomatira zopangidwa ndi hydroxyl polyurethane, mphira wachilengedwe kapena wopangidwa,

    Ili ndi mgwirizano wabwino kwambiri mphamvu mu rabara ndi kabati ntchito mu utomoni, antioxidant, plasticizing agent, pressure-sensitive etc.

    Itha kugwiritsidwa ntchito ngati crosslinker m'malo mwa BAYER's Desmodur RE

    RE 1

    Kugwiritsa ntchito

    Zomatira zamagulu awiri ziyenera kugwiritsidwa ntchito mkati mwa nthawi yomwe ingagwiritsidwe ntchito mutayika RE.

    Kutalika kwa nthawi yogwira ntchito sikungokhudzana ndi zomatira za polima, komanso zigawo zina zofunikira (monga utomoni, antioxygen, plasticizer, solvent, etc.

    Ikayandikira nthawi yoyenera, nthawi zambiri maola angapo kapena tsiku limodzi logwira ntchito, zomatira zimakhala zovuta kugwira ntchito, ndipo kukhuthala kumakwera posachedwa.

    Pomaliza, Imakhala yosasinthika odzola. 100 zomatira zabwino, Hydroxyl polyurethane (Polyurethane account pafupifupi 20%), RE mlingo 4-7. Chloroprene rabara (Rubber account pafupifupi 20%), RE imapanga 4-7.

    Kusungirako

    Chonde kusungidwa mumtsuko wosindikizidwa woyambirira pansi pa 23 ℃, zinthuzo zitha kusungidwa mokhazikika kwa miyezi 12.

    Imakhudzidwa kwambiri ndi ambiri; adzakhala kupanga mpweya woipa ndi insoluble urea mu anachita ndi madzi.

    Ngati kukhudzana ndi mpweya wa teh kapena kuwala, zidzafulumizitsa kusintha kwa mtundu, koma ntchito yothandiza sidzakhudzidwa.

    Phukusi

    750 g/botolo kapena 50 kg/ng'oma kapena 180 kg/ng'oma kapena kutengera zofuna za kasitomala.
