Compared to bare steel strand, galvanized steel strand ’ s anti - corrosion is worse in 3 % nacl solution. 3. the result of corrosion research in different ph value simulation acid rain show that bare steel strand has a low corrosion rate at ph = 4, corrosion rate at ph = 2 and ph = 6 is larger ; epoxy coating steel strand ’ s corrosion current intensity decrease with ph value ’ s minish ; reverse to epoxy coating steel strand, galvanized steel
3 、模擬酸雨中腐蝕研究結果表明,在不同ph值的模擬酸雨中,全裸鋼絞在ph = 4時腐蝕最慢, ph = 2時腐蝕最快, ph = 6時腐蝕速度居中;環氧鋼絞線腐蝕電流密度隨ph值的減小而減小;鍍鋅鋼絞與環氧鋼絞線剛好相反,腐蝕電流密度隨ph值的減小而增加, ph值越小,腐蝕電流密度越大,越容易遭受腐蝕。
