แผ่นเหล็ก Tinplate

Tinplate steel sheet is a steel product with a stampable thin steel plate as the base, tin-plated on its surface, and multiple layers of protective film (layers). It is corrosion-resistant, non-toxic, odorless, glossy, light, high strength (relative to paper, wood, and composite materials), easy to print, weld and process, and has strong adaptability to ambient temperature. Therefore, more than 70% of the total output of tinplate is used for food and beverage packaging. In addition, it is also the packaging and raw material for chemical, pharmaceutical, electromechanical, hardware, telecommunications and instrumentation industries.

Main Features

The main feature of tinplate steel sheet is that the tin-plated layer has the dual properties of electrochemical cathode and anode protection, that is, the potential of the inner wall of a food can filled with a complex mixture (or in a weak acid solution) and with a certain vacuum is lower than that of the matrix material iron. Tin is the anode, and its dissolution protects the iron. During the shelf life of the food can, the amount of tin dissolved is basically harmless to the human body; while its outer wall is in the atmospheric solution, the tin-plated layer is in a cathodic protection state, and has sufficient chemical stability, which is unmatched by other canning materials.
