盐雾箱试验是目前在实验室内评定防锈油性能优劣的一种重要试验方法。但是盐雾箱是一种专用设备,价格较贵,使用时常要人值班看管,而且在进行防锈油配方的筛选工作时,实验周期也显得太长。我们探索并试用了一种“显色试验”方法。从试验结果看,它可作为防锈油的一种简单而快速的评 Salt spray box test is currently in the laboratory to assess the pros and cons of anti-rust oil performance is an important test method. However, salt spray box is a special equipment, the price is more expensive, people often use duty custody, and in the screening of anti-rust oil formulations, the experimental period also appears to be too long. We explored and experimented with a “colorimetric test” approach. From the test results, it can be used as a simple and quick assessment of anti-rust oil
