The electrolytic aluminum industry is relatively weak in environmental supervision

The environmental supervision of the electrolytic aluminum industry is relatively weak. It is reported that in recent years, China’s electrolytic aluminum production capacity has increased rapidly, and the level of technology and equipment has been continuously improved. However, environmental protection technology research has lagged behind and environmental supervision is relatively weak. In accordance with the spirit and requirements of the State to stop blind investment in the steel electrolysis aluminum cement industry, the State Environmental Protection Administration issued a "Circular on Further Strengthening the Environmental Management of the Electrolytic Aluminum Industry" and requested that the environmental management of the electrolytic aluminum industry be further strengthened. The "Notice" proposed that local environmental protection departments at all levels must increase the environmental supervision of the existing electrolytic aluminum enterprises, strictly follow the time limit requirements of the state, and supervise the electrolytic aluminum enterprises within the jurisdiction to achieve the elimination of self-baked cells, and the eliminated production equipment must not be For any reason, transfer to other areas may not be changed from self-baked tanks to small pre-baked tanks. The “Notice” requires that the electrolytic aluminum construction project be further improved in environmental impact assessment. The construction project for the construction and expansion of the electrolytic aluminum production capacity must strictly implement the national industrial policy. After the country establishes the project, it submits the Environmental Impact Statement to the State Environmental Protection Administration in accordance with prescribed procedures.

Nickel Coating

Nickel coating is a type of metal coating that is applied to a variety of substrates, including stainless steel, copper, and aluminum, to enhance their properties for specific industrial applications. This process involves the electroplating of a thin layer of nickel onto the surface of the substrate, providing it with excellent corrosion resistance, wear resistance, and surface smoothness.

Nickel coating is widely used in industries where materials require protection from corrosion, such as in the automotive, aerospace, and manufacturing industries. It is particularly effective in environments where exposure to harsh chemicals or high temperatures can cause metal parts to degrade over time. The nickel coating acts as a barrier layer, preventing the substrate from coming into contact with these harmful agents.

In addition to its protective properties, nickel coating also improves the mechanical and physical qualities of the substrate. The smoothness of the nickel surface reduces friction, which can extend the lifespan of the substrate. Nickel coating also enhances the substrate's electrical conductivity, making it an ideal choice for electronic components and circuit boards.

Nickel coating can be customized to suit specific applications. For example, the thickness of the nickel layer can be increased to increase corrosion resistance and hardness. Other variations of nickel coating include nickel-cobalt alloy and nickel-phosphorous, which offer even greater protection and superior chemical and heat resistance.

In conclusion, nickel coating is a highly effective solution for protecting substrates from corrosion, wear, and tear. Its versatility and customizability make it an attractive choice for a wide range of industries and applications. By providing superior protection and enhancing the performance of substrates, nickel coating plays an important role in ensuring the longevity and reliability of industrial systems and components.
