Pali mabotolo 20000Desmodur REzilipo. Titha kutumiza katunduyo nthawi yomweyo tikalandira dongosolo.
Ngati mukufuna, kulandiridwa kuti mutiuze nthawi iliyonse, More kuchuluka ndi kuchotsera zambiri. Musati muphonye izo.

Mawonekedwe:RE ndi cholumikizira cholumikizira kwambiri, Chogwiritsidwa ntchito pazomatira zopangidwa ndi hydroxyl polyurethane, mphira wachilengedwe kapena wopangidwa,
Ili ndi mphamvu yolumikizana kwambiri mu rabara ndi kabati yomwe imagwiritsidwa ntchito mu resin, antioxidant, plasticizing agent, pressure-sensitive etc.
Itha kugwiritsidwa ntchito ngati crosslinker m'malo mwa BAYER's Desmodur RE.
Kagwiritsidwe: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.
Kuphatikiza apo: Kampaniyo imatha kufufuza ndikupanga zinthu zatsopano malinga ndi zomwe makasitomala athu amafuna.
