Aluminium scrap recovery

Tianjin scrap aluminum recyclingThe meaning of

Among the structural metals used in industry, aluminum has high recyclability and great recovery efficiency。Due to the high corrosion resistance of aluminum, in addition to some aluminum chemical containers and devices, aluminum products will almost not be corroded during use, such as aluminum doors and Windows of buildings, high-voltage transmission and distribution lines, aluminum structures and parts of transport vehicles, aluminum cans, etc。They suffer only a small amount of corrosion loss during "use" and can be almost completely recycled。

Although aluminum has strong corrosion resistance, it will also be subjected to a certain degree of corrosion in the atmosphere。When it comes into contact with some chemicals such as alkali, seawater, soil, etc。Strong or violent chemical reactions can occur, causing environmental pollution。The pollutants discharged in the process of waste aluminum recycling are far less than the pollutants discharged in the whole process of primary aluminum production, and the degree of environmental pollution is much lighter, only about 10% of the latter。It can be seen that the recycling of waste aluminum is a "green project" that benefits present and future generations.。

Starting in the 1950s, China began to recycle scrap aluminum。However, for a long time, the recycled aluminum recycling industry is only a marginal industry in China's aluminum industry, and the statistical analysis data in this aspect is less, which brings great difficulties to the research of the recycled aluminum industry。The secondary aluminum industry is gradually developed with the birth of the aluminum industry, but only after the accumulation of a certain amount of aluminum products in society, it really forms an independent industry。
