Tin and tinSince the back skin as long as tinplate will rust, so why not replace tin?
Tin, also called galvanized sheet steel, atmospheric corrosion resistance ability is strong, not afraid of the rain and wind, used for building materials, general exposure in the air. Such as color plate, color steel. Because it is hard, so it is not easy to physical erosion. If the galvanized layer off, the same will rust.Can not be used. Instead of using tin tin galvanizing vessel, it is easy to cause zinc poisoning. Zinc soluble in acid, acid resistance is poor, so the tin can not be used for beverage packaging, such as carbonated drinks and fruit juice. In addition some foods, such as aquatic products, or products such as packaging, the requirements are higher, need to use advanced professional tinplate.
Oftinned is actually, tinplate, commonly used in food and beverage packaging, have good anti-corrosion effect, and no harm to human body. We used a lot of tinplate cans, is done. The tinplate back skin, is actually the plate above the tin, is physical effect eroded, so the steel will rust.
Tin and tin, are plated plate, is a low carbon steel sheet, and metal coating. Electroplating and hot plating respectively.The difference between the two plates is that the former tin plated, the latter galvanized, because the two kinds of metals have different chemical properties, so their anti-corrosion ability and use is not the same
