金属部件加工出来后需要防锈油防锈,在仓库封存中要用油脂封装等也都与油脂接触。这些油污与金属表面的结合度各不相同,有些油污较稀薄则结合度中等,要清洗洁净较为简单容易,有些稠厚的油污比较复杂,它和表面的浮锈、铁屑、沙尘等结合对金属表面的附着力很强,很难清理,必须考虑多种方法,甚至多次清洗工序才能达到需要的清洁度。所以金属表面油污的清洗时金属表面处理中一道必经的工序,也是表面洁净的一道关键性的工序。
金属表面的锈层主要是指钢铁表面的铁锈,包括浮锈和厚锈层。铁锈来源于加工和放置过程中。钢铁材料是活泼的金属材料,很容易和空气及环境介质中的氢气结合产生氧化物。在机械的冷热加工的过程中,钢铁表面不断和氧气接触,特别是在高温的情况下很快生成氧化铁,即为铁锈。铁锈随钢铁材料的种类不同,接触的环境介质以及铁锈生成的时间不同而有较大的差别,有灰暗色,黄褐色,棕色,甚至灰黑色多种,惩罚可能是氧化铁,三氧化二铁,氢氧化铁或者是它们的混合物。
Need of rust-preventive oils after processing of metal parts, in the warehouse storage to have contact with the grease grease package etc.. These oil and metal surface binding degree each are not identical, some thin oil with medium, is simple and easy to clean, some thick oil is more complex, and its surface rust, dust, iron filings with the surface of the metal adhesion is strong, it is difficult to clean, must consider various methods, even repeated cleaning process to achieve cleanliness required. So a necessary metal surface treatment process for cleaning metal surface greasy dirt, a key step is the clean surface.
The rust layer on metal surface mainly refers to the steel surface rust, including rust and thick rust layer. Rust from processing and placed in the process of. Iron and steel material is a metal material and lively, easy and the air and the environment medium hydrogen combine to produce oxide. In the process of hot and cold processing
