为了对铬锰合金钢的防锈包装设计提供基本参数,通过实验研究了铬锰合金钢锈蚀与环境相对湿度及时间的关系,对几种典型的防锈包装技术的防锈效果进行了对比分析。 结果表明:在自然环境下,铬锰合金钢自身的防锈性能可以保证至少 35 d 的防锈期,35 d 后锈蚀就会出现并随着相对湿度的增加而加速;防锈包装以防锈剂和防锈膜组合为最佳。 将研究结果应用到某铬锰合金钢制品的防锈包装,并通过加速试验进行了防锈效果验证。 结果表明,该防锈包装至少可保证被包装产品 1 年内不出现锈蚀现象。

In order to provide basic parameters for rustproof packaging of Cr-Mn alloy steel, the relationship of corrosion rate with environmental humidity and time was studied by experiment. The effects of several typical rust-proof packaging technologies were compared. The results showed that the antirust period of Cr-Mn alloy steel in natural environment is about 35 days; after the antirust period, the rust will appear and accelerate with increasing of temperature and humidity; the composition of rust inhibitor and antirust film is the best antirust packaging method. The research results were applied to the rust-proof packaging of a Cr-Mn alloy steel products, and the rust-proof effect was verified through acceleration test. The results showed that the rust-proof packaging can ensure product to have no corrosion phenomenon at least one year.
