Pali mabotolo a 30000 RFE omwe ali m'gulu. Amatha kubereka mwachangu. Kuchuluka kochulukira ndi kuchotsera. Ndikukhulupirira kuti simuziphonya.
Ngati mukufuna, talandiridwa kuti mutilankhule nthawi iliyonse

Kuphatikiza apo:Kampaniyo imatha kufufuza ndikupanga zinthu zatsopano malinga ndi zomwe makasitomala athu amafuna.
Mawonekedwe: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.
Kagwiritsidwe: 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 kwambiri
ntchito, ndipo mamasukidwe akayendedwe amawuka posachedwapa. 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.
Posungira: Chonde sungani mumtsuko wosindikizidwa woyambirira wosachepera zaka 23℃, mankhwalawo akhoza kusungidwa mokhazikika kwa miyezi isanu ndi umodzi. Zogulitsa zonse za Crosslinker zimakhudzidwa kwambiri ndi chinyezi; idzatulutsa mpweya woipa ndi urea wosasungunuka mumadzi. Ngati kukhudzana ndi mpweya kapena kuwala, izo kufulumizitsa kusintha mtundu wa mankhwala, Koma ntchito zothandiza sizidzakhudzidwa.
