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 kukalamba ndipo uli ndi zotsatira za kuwonongeka kwa peroxides.Mankhwalawa ali ndi kutentha kwambiri.Ikasakanikirana ndi imidazole ndi ma antioxidants ena, imakhala ndi chitetezo ku kuwonongeka 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 ℃.
