Nail surface treatment process
1. Rust removal
Rust is easy to appear on the surface of nails, which affects the quality and service life of nails. Therefore, rust removal is the first step in the surface treatment of nails. Generally, mechanical rust removal, chemical rust removal and electrochemical rust removal are used. The corresponding rust removal method is selected according to the material and degree of rust of the nails.
2. Cleaning
After removing the rust, there are still some grease, dust and other dirt on the surface of the nail, which needs to be cleaned. The purpose of cleaning is to remove impurities on the surface of the nail and make the surface smoother.
3. Pickling
After cleaning the surface of the nail, some oxide scale and rust are not completely removed. At this time, pickling treatment is required, and the corrosive effect of acid can be used to dissolve the oxide scale and rust on the surface of the nail.
4. Phosphating
After pickling, the surface of the nail becomes very clean, but lacks a protective layer. Phosphating is to form a phosphating film on the surface of the nail, the purpose of which is to improve the corrosion resistance and coating of the nail. Phosphating is generally carried out with phosphate solution.
5. Electroplating
After the surface of the iron nail is phosphated, it can be plated to enhance the corrosion resistance and aesthetics of the iron nail. Electroplating is divided into zinc plating, nickel plating, chrome plating and other types. Choose the appropriate electroplating method according to different uses and requirements.
6. Painting
After the electroplating treatment is completed, the iron nail can be painted to make its surface more beautiful and durable. Painting is mainly divided into two methods: spraying and dipping. Choose the appropriate painting method according to actual needs.
The surface treatment process of iron nails includes rust removal, cleaning, pickling, phosphating, electroplating and painting, and each link is very important.
