生锈是由于金属周围媒介物的影响,而引起的破坏,金属防锈是极为细致和困难的工作,由于金属产品在加工过程中的特点,特别是轴承工业,在许多工序中,有手汗和产品接触,因而在其表面上常带有手汗指纹.汗水的化学成份是食盐和一系列有机酸的水溶液,因此由于人们的汗手与金属接触的结果,在金属的表面留有指纹这会加速金属腐蚀,即是涂上一层很好的防锈剂,亦不能得到很好的防锈效果.要消除金属上指纹的印痕,通常用水溶液是不能清除干净的.假使用甲醇来洗涤或擦洗,由于这些方法对操作者的健康有影响,而且容易引起火灾,处理后又不能再用手与金属接触,这是很不方便的,因此有必要研究用中和置换性溶液来清除加工后接触的腐蚀生成物.
Rust is due to the impact of the surrounding metal media, which caused the destruction of metal rust is a very detailed and difficult work, due to the characteristics of metal products in the processing process, especially the bearing industry, in many processes, hand sweat And the product, and therefore often hand sweat fingerprints on its surface.Chemical composition of sweat salt and a series of organic acid aqueous solution, so as a result of the human sweat hand and metal contact, there is a finger on the metal surface which Will accelerate the metal corrosion, that is coated with a good anti-rust agent, also can not get a good anti-rust effect.To eliminate the fingerprints on the metal, usually with an aqueous solution can not be cleaned.If the use of methanol to wash Or scrubbing, as these methods have an impact on the health of the operator and can easily cause a fire, it is inconvenient to dispose of the metal by hand after the treatment. Therefore, it is necessary to study the method of neutralizing the solution with a neutralizing solution After contact with the corrosion products.
