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 、模拟酸雨中腐蚀研究结果表明,在不同ph值的模拟酸雨中,全裸钢绞在ph = 4时腐蚀最慢, ph = 2时腐蚀最快, ph = 6时腐蚀速度居中;环氧钢绞线腐蚀电流密度随ph值的减小而减小;镀锌钢绞与环氧钢绞线刚好相反,腐蚀电流密度随ph值的减小而增加, ph值越小,腐蚀电流密度越大,越容易遭受腐蚀。
