1. The structure of tinplate
Tin Plate (Tin Plate) is also called tin-plated steel plate. It is made of tin plated on a thin steel plate substrate. It is composed of oil film, iron oxide, tin layer, alloy layer, and substrate. It combines the strength and formability of steel with tin. Corrosion resistance, solderability and beautiful appearance are combined into one material, which has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.
2. Characteristics of tinplate
â‘ Opacity: Tinplate has good opacity, which can effectively prevent the radiation of visible light and ultraviolet rays, protect the food from corrosion and deterioration, and extend the shelf life.
â‘¡Good sealing: The good sealing of tinplate makes it block the effect of air and other gases on the protection of canned products, especially food, when making packaging containers.
â‘¢Good environmental protection: Tinplate is a material that can be completely recycled, which is conducive to protecting our living environment. In addition, tinplate can decompose naturally in the environment, and will not cause residual pollution.
â‘£Energy saving: The production of steel with tinplate scraps saves energy compared to the production of steel with iron ore. Each ton of scrap iron scrap can save about 230 m3 of natural gas.
