1. The structure of tinplate products
tinplate products, also known as tin plate, is made by plating tin on a thin steel plate substrate. tinplate products is composed of oil film, iron oxide, tin layer, alloy layer, and substrate. It combines the strength and formability of steel with that of tin. Corrosion resistance, solderability and beautiful appearance are combined in one material, which has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.
2. The characteristics of tinplate products
①Opacity: tinplate products have good opacity, can effectively prevent visible light and ultraviolet radiation, can protect food from corrosion and deterioration, and extend the shelf life.
②Good airtightness: The good airtightness of metal tin plates makes it protect canned products, especially food, by blocking air and other gases when making packaging containers.
③Good environmental protection: tin plate sheet is a material that can be completely recycled, which helps protect our living environment. In addition, metal tin plates can decompose naturally in the environment and will not remain and cause environmental pollution.
④ Energy saving: using metal tin plates scraps to produce steel is more energy-efficient than using iron ore to produce steel. Each ton of scrap iron scraps can save about 230m3 of natural gas.
