加强废5052合金铝板板的预处理5052合金铝板板及其合金在加工制造过程 中，企业往往会对金属表面进行处理，喷涂各种涂料或包覆各种有机（无机）材料等，其中可能会加入酸、碱、盐和油等物质。因此，5052合金5052合金铝板板及其制品在使用或消费之后 进入报废领域，其本身就带有污染物。
Strengthen the 5052 aluminium alloy plate waste pretreatment of 5052 aluminium alloy plate and its alloy in the manufacturing process, companies often for metal surface treatment, spray coating or coating of various organic materials (inorganic), which may be added to acid and alkali, salt and oil and other substances. Therefore, the 5052 alloy 5052 alloy aluminum plate and its products enter the waste field after use or consumption, and they have pollutants in themselves.
此外，废5052合金5052合金铝板板来自社会各个角落，种类繁多，在回收和拆解过程中受到过不同程度污染，会夹杂各种非5052合金5052合金铝板板物质，这些夹杂物也会 在熔炼过程中发生物理和化学反应，对环境产生一定的影响。因此，应该重视废5052合金5052合金铝板板的预处理，使夹杂的污染物消灭在熔炼之前。

In addition, the waste of 5052 alloy 5052 alloy aluminum plate from every corner of the society, variety, have varying degrees of pollution in the recycling and dismantling process, will be mixed with a variety of non alloy 5052 alloy 5052 aluminum plate material, these inclusions also occur in the physical and chemical reaction in the smelting process, have a certain impact on the environment. Therefore, we should pay attention to the pretreatment of the waste 5052 alloy 5052 alloy aluminum plate, so that the contaminants of the inclusions should be eliminated before melting.
预处理技术主要包括：分选，即分选出塑料、橡胶等非5052合金5052合金铝板板物质；洗涤，即洗掉废5052合金5052合金铝板板中的油污等物质；脱漆，为减少废5052合金5052合金铝板板表面涂层不完全燃烧产生的污染，应注重涂层废5052合金5052合金铝板板在入炉之前的脱漆处理。
The pretreatment technology mainly includes: sorting, namely choose plastic and rubber non alloy 5052 alloy 5052 aluminum plate material; washing, wash the waste of 5052 alloy 5052 aluminium alloy plate in the grease paint, to reduce waste; 5052 alloy 5052 alloy surface coating of aluminum plate produced by incomplete combustion of pollution, should pay attention to the coating waste 5052 alloy 5052 alloy aluminum plate in the paint into the furnace before treatment.
预处理的同时，也分离出了各种非5052合金5052合金铝板板物质，得到了纯净的废5052合金5052合金铝板板，这亦是熔炼高质量5052合金苏州5052合金铝板板合金的必要保障。由于大量的夹杂物已经在熔炼之前去掉，因此减少了添加剂的用量，缩短了熔炼周期，生产成本相应下降，这就显示了环境管理的优势。
At the same time, various kinds of non 5052 alloy 5052 alloy aluminum plate material were also separated, and pure waste 5052 alloy 5052 alloy aluminum plate was obtained. This is also the necessary guarantee for smelting high quality 5052 alloy Suzhou 5052 alloy aluminum plate alloy. Because a large number of inclusions have been removed before smelting, the amount of additives is reduced, the smelting cycle is shortened, and the production cost decreases accordingly, which shows the advantages of environmental management.
