Zogulitsa & Zida

RE yathu ndi yolumikizira yolumikizana kwambiri, Yogwiritsidwa ntchito pazomatira zopangidwa ndi hydroxyl polyurethane, mphira wachilengedwe kapena wopangira, ili ndi mphamvu yolumikizana kwambiri mu raba ndi kabati yogwiritsidwa ntchito mu utomoni, antioxidant, wothandizila kupangira pulasitiki, wovuta kukakamiza etc. itha kugwiritsidwa ntchito ngati cholumikizira m'malo mwa BAYER's Desmodur RE.

Kugwiritsa ntchito

Zomatira ziwiri ziyenera kugwiritsidwa ntchito munthawi yomwe mungagwiritse ntchito mutayika RE. Kutalika kwa nthawi yogwiritsidwa ntchito sikukhudzana kokha ndi zomata za polima, komanso zinthu zina zofunikira (monga utomoni, antioxygen, plasticizer, zosungunulira, ndi zina. Mukakhala pafupi ndi nthawi yofunikira, nthawi zambiri maola ochepa kapena tsiku limodzi logwira ntchito, zomatira Zimakhala zovuta kuyigwiritsa ntchito, ndipo mamasukidwe akayendedwe amakula posachedwa. , RE wathu amachita 4-7.

Zolemba Zina Zofananira

Yosungirako:

Chonde chosungidwa mumtsuko woyambirira wosindikizidwa pansi pa 23 ℃, malonda atha kusungidwa okhazikika kwa miyezi 12. Ndizovuta kwambiri ku the mosture; idzakhala yopanga carbon dioxide ndi insoluble urea poyankha ndi madzi. Ngati kuwonetsedwa ndi mpweya wa teh kapena kuwala, kumathandizira kuti mitundu isinthe, koma magwiridwe antchito sadzakhudzidwa.
