Katundu
White ufa. Osanunkhiza koma kukoma kowawa. Kusungunuka mu acetone, mowa, osasungunuka mu benzene, petulo ndi madzi.
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.Zofanana ndi antioxidant MB, ndi mchere wa zinki womwe ungagwiritsidwe ntchito mwachindunji popanda ukalamba ndipo uli ndi zotsatira za kuwonongeka kwa peroxides. Mankhwalawa ali ndi kutentha kwambiri. Ikasakanikirana ndi imidazole ndi ma antioxidants ena, imakhala ndi chitetezo pakuwonongeka kwa mkuwa. Itha kugwiritsidwa ntchito ngati chothandizira thermosensitizer ya latex thovu pawiri kupeza zinthu thovu ngakhale thovu, komanso ngati gelling wothandizila latex dongosolo.
2.Amapangidwa bwanji:
(1) Kuwonjezera madzi sungunuka nthaka mchere njira yothetsera amadzimadzi a mchere zitsulo zamchere wa 2-mercaptobenzimidazole kuchita;
(2) Pogwiritsa ntchito o-nitroaniline monga zopangira, o-phenylenediamine amapangidwa mwa kuchepetsa, ndiyeno anachita ndi carbon disulfide mu sodium hydroxide njira kupanga 2-mercaptobenzimidazole sodium. Pambuyo pakuyenga, mchere wa sodium umasungunuka m'madzi, ndipo zinc aluminide imawonjezeredwa ku njira yake yamadzi.
3. Malo owonongeka ndi apamwamba kuposa 270 ℃.
