Katundu
White ufa. Osanunkhiza koma kukoma kowawa. Kachulukidwe ndi 1.42. Kusungunuka mu mowa, acetone, ethyl acetate, kusungunuka pang'ono mu petroleum ether, CH2Cl2, osasungunuka mu CCl4, benzene ndi madzi. Kukhoza bwino kukhazikika kosungirako. Monga antioxidant yachiwiri popanda posion.
Kugwiritsa ntchito
Antioxidant yachiwiri yosadetsa kwa NR, CR, SBR, NBR ndi EPR etc. Zothandiza kwambiri polimbana ndi kutentha kwa okosijeni pamodzi ndi amine.
Phukusi
25kg kraft paper bag.
Kusungirako
Zopangirazo ziyenera kusungidwa pamalo owuma ndi ozizira ndi mpweya wabwino, kupewa kukhudzana ndi zomwe zapakidwa ndi dzuwa. Zovomerezeka ndi zaka 2.
Zowonjezera zokhudzana
1.Mainly amagwiritsidwa ntchito mu mphira wopangidwa, cis-1,4-polybutadiene rabara, mphira wa styrene butadiene, mphira wa nitrile, latex, etc.
2.Antioxidant MB ndi yaikulu yosaipitsa antioxidant mu mphira makampani, amene angathe kuchepetsa kusinthika kwa mphira pa vulcanization, Kuthandiza kupewa mpweya kukalamba labala. Izi ndizoyenera kupanga zinthu zowonekera, zoyera komanso zokongola, zosagwira kutentha komanso thovu. Sichimasintha mtundu ndipo sichiipitsidwa. Amagwiritsidwa ntchito mu mawaya, zingwe, mandala kuwala akuda mankhwala, komanso monga kutentha stabilizer kwa polyethylene ndi polypropylene.
3.Monga kuwala kwa plating yamkuwa, kungapangitse kuti plating ikhale yowala komanso yosalala, komanso imatha kusintha kachulukidwe kameneka kakugwira ntchito. Nthawi zambiri amagwiritsidwa ntchito molumikizana ndi zowunikira zamkuwa za N, SP, etc.
4.Antioxidant MB imatha kuteteza bwino kuwonongeka kwa mkuwa ndikugonjetsa zovuta zomwe zimachitika chifukwa cha sulfure wochuluka. Zili ndi zotsatira zochedwetsa pa ma accelerators monga MBT ndi MBTS, ndipo zimakhala ndi mgwirizano wa amine ndi phenolic antioxidants.
