How can we prevent iron barrels from rusting? Everyone knows that iron barrels are particularly prone to rust after a period of use, but in fact, there are ways to prevent iron barrels from rusting. The following editor will introduce you to several commonly used methods.
1. The composition of the alloy changes the internal structure of iron. metals such as chromium and nickel can be added to ordinary steel to make stainless steel, which can greatly increase the rust resistance of steel products.
2. A more common and commonly used method is to cover the surface of iron products with a protective layer to prevent iron products from rusting. According to the composition of the protective layer, it can be divided into the following types:
①Apply mineral oil, paint or enamel, plastic spray, etc. on the surface of iron products, such as paint the car compartment, bucket, etc., and the machine often paints mineral oil
②镀一层我tal罗斯并不容易t on the steel surface by electroplating or hot-dip plating. These metals will form a protective film to prevent the iron barrel from contacting with water, air and other substances to rust.
③ Using chemical methods, a dense and stable oxide film can be formed on the surface of iron drums to prevent iron products from rusting.
