The impact of aluminium alloy die-casting on the environment and countermeasures
2025-01-03
Aluminium alloy die-casting products are highly favoured in modern industrial production, and their lightweight and durable characteristics are widely used in automobiles, electronics, aviation and other fields. However, the production and use of aluminium alloy products also brought some negative impact on the environment and human health. This article will be introduced from the aluminium alloy die casting on the environment and countermeasures in two aspects.
Aluminium alloy die casting on the environment
The impact of aluminium alloy die casting on the environment mainly includes the following aspects.
Energy consumption
Aluminium alloy die-casting needs a lot of energy, especially electricity and gas, which is a burden for the environment. Moreover, the electricity used in the production process of aluminium alloy often comes from coal-fired or oil-fired power plants, which will produce a large amount of carbon dioxide and other greenhouse gases, exacerbating global climate change.
Water Consumption
Aluminium alloys also require a large amount of water in the production process. Particularly in the casting process, large amounts of cooling water are used. However, due to regional and seasonal water shortages, many casting companies use cooling water that is repeatedly used rather than purified water, which affects water quality and the surrounding environment to a certain extent.
Chemical pollution
Aluminium alloy die casting production need to add additives, additives and surface treatment agent contains a variety of chemical composition, which harmful substances, such as heavy metals, organic matter will be polluted through the emission of the atmosphere, water and other environments, resulting in environmental chemical pollution, ecological environment damage.
Aluminium alloy die casting on the environment response measures
At present, the increasing depletion of fossil energy resources, the reduction of water resources and other issues, there is an urgent need for aluminium alloy industry to strengthen energy saving and emission reduction, reduce the harm to the environment, the following are some countermeasures:
Energy saving and emission reduction
Aluminium alloy industry should actively explore new energy saving and emission reduction technology and application, such as the use of oxygen violence combustion, nitrogen protection melting and other technologies, reduce electricity consumption, reduce fossil energy extraction and combustion and other emission reduction measures.
Governance of water resources
Aluminium alloy products manufacturing enterprises should establish water resources management system, implement rational use of water resources, and improve the reuse and saving of water resources, such as adopting advanced tap water purification technology and recycling cooling water.
Environmental protection technology
Aluminium alloy production should be combined with the development of advanced science and technology and the introduction of foreign advanced technology, for example, the surface treatment method is changed to environmentally friendly technology, for example, the electroplating process is changed to environmentally friendly methods such as silk screen printing and spraying.
