Copper process breakthrough and auxiliary materials collaborative innovation road

In the development process of copper industry, the collaborative innovation of

process breakthrough and auxiliary materials is like the wings of a bird and the two wheels of a car, which jointly promote the performance improvement and application expansion of copper. In the face of the growing market demand and fierce industry competition, exploring the path of copper process breakthrough and the mode of collaborative innovation between auxiliary materials and it has become the key to the development of the industry.

Smelting process: precise control and optimization of auxiliary materials

Smelting is the starting link of copper production, and its technological level directly affects the purity and quality of copper. The traditional smelting method has some limitations in impurity removal and composition uniformity control.

Nowadays, advanced melting technology is moving towards precise control. For example, the use of vacuum melting technology, by melting in an extremely low pressure environment, can effectively reduce gas mixing, greatly reduce the porosity, inclusion and other defects in copper. At the same time, the use of advanced spectral analysis, mass spectrometry and other real-time monitoring

 

means, precisely adjust the content of alloying elements in copper liquid, so that the composition deviation is controlled in a very small range.

In this process, the role of excipients is crucial. As a key auxiliary material, the refining agent can chemically react with the impurities in the copper liquid to form the furnace slag that is easy to separate, thus improving the purity of the copper. In the process of research and development of the new refining agent, attention is paid to improving its reactivity and selectivity, to ensure that the loss of beneficial alloying elements in the copper liquid is minimized while removing impurities. For example, refining agents containing specific rare earth elements can more efficiently remove impurities such as sulfur and oxygen in copper liquid, while refining grains, improving the microstructure of copper, and enhancing its comprehensive performance.

 

Molding process: multiple innovation and auxiliary material adaptation

The molding process determines the final shape and dimensional accuracy of the copper material. In extrusion molding, copper profiles with complex cross-section shapes can be produced by optimizing die design and accurately adjusting extrusion parameters. In order to meet the needs of this process, lubricant as an important auxiliary material, plays an irreplaceable role. High-quality lubricant can form a uniform lubricating film on the surface of copper and mold, reduce the friction coefficient, reduce extrusion pressure, prevent scratches on the surface of copper and improve the surface quality of profiles. The research and development of lubricants with high temperature stability and high lubrication performance has

 

become a hot spot in the industry. For example, the lubricant with synthetic ester as the base oil and special additives can maintain good lubrication effect under high temperature and high pressure extrusion environment to ensure the smooth extrusion of complex copper profiles.

The forging process is also constantly innovating. By precisely controlling the forging temperature, pressure and deformation amount, the hot die forging technology makes the internal structure of copper more dense, the grain fine, and significantly improve the strength and toughness of parts. In the forging process, release agent is an essential auxiliary material. The new release agent should not only have good release performance, but also keep stable in high temperature environment and do not react with copper. Water-based release agent has gradually become the mainstream because of its environmental protection characteristics and good release effect. By optimizing the formula, it can quickly form a layer of isolation film during high temperature forging, which helps the forging release smoothly and reduces the pollution to the environment at the same time.

 

Surface treatment process: performance improvement and auxiliary materials

cooperate

Surface treatment process is the key link to improve the added value and comprehensive performance of copper. In the electroplating process, in order to form a uniform and dense metal coating on the copper surface, the formula of the electroplating solution is very important. New electroplating solutions continue to

 

emerge, such as adding specific organic additives to the copper plating solution, which can change the deposition mode of copper ions, make the coating more flat and bright, and improve the corrosion resistance and binding force of the coating. These additives and copper ions in the electric field synergistic action, control the crystal growth direction, so as to obtain the ideal coating performance. The chemical conversion film treatment process provides an environmentally friendly and efficient protection method for copper. In the process of forming the chemical conversion film, the composition of the treatment liquid determines the quality and performance of the film. Research and development of new treatment liquid, so that it can quickly form dense and stable chemical conversion film on the surface of different copper materials, has become a research focus. For example, the treatment liquid containing zirconium, titanium and other elements can chemically react with the surface of copper to generate a composite conversion film with good corrosion resistance and wear resistance, effectively improving the service life of copper in harsh environments.

 

Future outlook: Continuous innovation and deep collaboration

With the continuous progress of science and technology, copper technology will develop in the direction of more intelligent, green and high performance. In terms of process breakthrough, digital simulation technology will be widely used in melting, molding and other links, through the simulation to predict the change of various parameters in the process, optimize the process plan in advance, and improve production efficiency and product quality. In the innovation of excipients,

 

the research and development of excipients with multi-functional characteristics and environmental friendliness will become a trend. For example, excipients with lubrication, rust prevention, antibacterial and other functions can reduce the processes in the production process, reduce costs, and meet environmental protection requirements.

Copper process breakthrough and auxiliary materials collaborative innovation is a mutually reinforcing process. Only by constantly promoting process innovation, can the research and development direction of excipients be clear; And the continuous optimization of auxiliary materials provides a strong support for the process breakthrough. In the future, the copper industry needs to strengthen the cooperation between industry, university and research, integrate the resources of all parties, jointly explore a new model of collaborative development of process and auxiliary materials, inject new vitality into the high-quality development of the copper industry, expand the application boundary of copper in more fields, and create greater value.
