Regarding the recycled aluminum, since the popularity of electronic products, there have been countless pollutions in this area. Today, the harm caused by electronic waste to our lives has reached a level that cannot be ignored, not only causing resource consumption, but also causing huge Environmental pollution.
Although the environmentally friendly aluminum smelting method reduces greenhouse gas emissions, it cannot reduce the exploitation of natural resources.
Aluminum resources are mineral resources, and mineral resources are non-renewable resources, that is to say, we use a little less; aluminum smelting belongs to a high energy consumption and high pollution industry, and its adverse effects on the environment are obvious. Therefore, recycling aluminum is a very meaningful job, whether it is from an economic or environmental perspective. Because of this, aluminum recycling has become an industry. Whether it is cans or aluminum sheets, a huge recycling industry chain has been formed.
Although the proportion of aluminum recycling is quite high overall, the global aluminum recycling industry has developed unevenly.
The cost of aluminum from ore to metal to finished product is extremely high and consumes huge energy. It takes 1,3000-15,000 watts of electricity per hour to produce one ton of metal aluminum in one electrolysis process. The regeneration and reuse of waste metal aluminum and aluminum scraps can greatly reduce energy consumption and auxiliary material consumption, saving resources and costs. Therefore, the recovery and reuse of waste aluminum scraps are of great significance in terms of saving resources on the earth, saving energy, cost, shortening the production process cycle, or environmental protection and improving the human ecological environment.
Civil, military, construction, transportation, transportation, electronic telecommunications, household appliances, electricity, machinery... Aluminum alloy is almost ubiquitous in all walks of life. With the increase in output and usage, the amount of waste aluminum products is also increasing. Moreover, many aluminum products are secondary use, and the time from the finished product to the product loss of use value is relatively short. Therefore, these waste miscellaneous materials have become a source of pollution. The issue of how to use recycled aluminum is very urgent.
Secondary aluminum has an increasingly prominent position in aluminum production in major developed countries. The ratio of primary aluminum to secondary aluminum in developed countries has approached or exceeded 1:1. Because of this, the recycling of waste aluminum has become an important work in the world and has become an important industry.
The recovery and regeneration of aluminum is a very complex technical task. Various aluminum products have a wide range of use, scattered use, how to recycle, concentrate, sort, and then realize regeneration processing are all very complicated and huge projects. Secondly, there are hundreds of alloys with different alloy compositions and different properties in the world, and the constituent elements in many alloys are mutually exclusive and incompatible with each other. How to use the easiest method, the lowest cost, and the most effective process to make the waste A1 regenerated composition meet the ideal alloy requirements, the performance meets the use, and the quality can reach or be close to the level of the original material.
