​Tinplate ( SPTE ) is a common name for electroplatedtinsteel sheets, which refers to cold-rolled low-carbon steel sheets orstrips coated with commercial pure tin on both sides. Tin mainly acts to prevent corrosion and rust. It combines the strength and formability ofsteel with the corrosion resistance, solderability and aesthetic appearance of tin in a material with corrosion resistance, non-toxicity, high strength and good ductility.

1. Low pollution: tinplate, the main raw material in tin can containers, is in fact environmentally harmless and can be decomposed naturally. Because when tin can exist in the environment, it can be oxidized naturally and returned to the original state of iron oxide, thus returning to nature, so the stacking of scrap iron can be decomposed by time and will not cause environmental pollution. Dyed. At the same time, making iron can not cut down trees, and do not damage the ecological balance.

2. Recyclable: The iron can itself has a characteristic that other packaging materials do not have - can be adsorbed by magnets, so that the iron can can be separated from the waste by magnetic force by magnetic separator, using this characteristic can easily achieve the effect of recycling 80% of the iron can in waste. The invention of environmental protection cover not only makes the use of iron cans safer and healthier, but also effectively reduces the amount of garbage, and has direct and obvious benefits for recycling operations.

3. Provide resources: In the removal of other contaminated residues on iron cans, the shredder equipment has been developed, which can effectively remove more than 98% of the pollutants and provide scrap iron with good quality.
