钢铁零件经过发兰处理以后,生成一层黑色氧化膜,为了提高其耐腐蚀性能,一般氧化以后,再涂锭子油或机油作为提高耐腐性的补充处理。我车间采用这一工艺已有十多年。在生产实践中发现锭子油或机油本身防腐性较差,经过发兰涂油后的零件长期存放或在霉雨季节时表面仍会生锈,而且涂油工艺需要加温,温度控制在105℃—115℃,消耗大量电能,在大批量生产中,油污染环境,影响车间的文明生产和安全生产,也影响操作工人的健康。为了克服以上弊病,改进目前的涂油工艺。武汉材料保护研究所最近研制成功新型的P—2乳化
Iron and steel parts after the treatment of blue hair, the formation of a layer of black oxide film, in order to improve its corrosion resistance, the general oxidation, then coated spindle oil or oil as a supplementary treatment to improve corrosion resistance. I have been using this process for more than a decade in my workshop. Spindle oil or oil found in production practice itself poor corrosion resistance, after the long hair blue oil coated parts or in the moldy season when the surface will rust, and oiling process requires heating, temperature control at 105 ℃ -115 ℃, consume a large amount of electricity, in mass production, the oil pollution of the environment, affecting the plant’s civilized production and safety in production, but also affect the health of workers. In order to overcome the above defects, improve the current oiled process. Wuhan Institute of Materials Protection recently developed a new type of P-2 emulsification
