tinplate

          Thin steel plate that Wuxi, China since been extended to 80 years, has been in a wandering state, until after 2000, only to be universally applied, even in this year there will be tin-plated iron ferrochrome expensive than the price situation, the reason is plated with chromium in Indian iron coating process is superior to tinned iron. With the widespread use of iron paint, especially in the cap, the more chromium-plated by the people's attention, and chromium plating is characterized by: (1) processing and canning substrate corrosion resistance of the substrate with the same tin; (2) coating process, the need to consider issues such as tin tin melting, higher baking temperature can be used to improve the efficiency of printed and coated production; (3) the adhesion of the coating, superior to tin; (4) the surface is a layer of thin layer of chromium and hydrated chromium oxide layer, the thickness of tin layer of about 1% tin. So easy to rust. So, without coating process, there is no chrome-plated practical value. (5) because it is Wuxi sheet, so save the tin resources in line with the development direction of tinplate.
