With the continuous development of science and technology, metal meshes are more and more widely used in many fields, such as electronics, optics, precision instruments and so on. As an important material for electronic components, the surface quality of metal mesh has a crucial impact on product performance. Therefore, it is of great significance to study the polishing method of metal mesh to improve its surface quality. In this paper, we will discuss the polishing method of metal mesh, in order to provide certain reference for the field of metal mesh manufacturing.
I. Overview of metal mesh
Metal mesh is a kind of metal wire as the basis, after a certain weaving, arranging, welding and other processes made of mesh structure. Metal mesh has excellent electrical conductivity, thermal conductivity, corrosion resistance and mechanical strength, and is widely used in electronics, optics, precision instruments and other fields. However, in the manufacturing process of metal mesh, its surface often produces certain roughness and defects, so it needs to be treated by polishing methods to improve its surface quality.
Second, the study of metal mesh polishing methods
- Mechanical polishing
Mechanical polishing is the most common metal grid polishing method, mainly using polishing wheels, polishing liquid and polishing cloth and other materials to rub the surface of the metal grid, so that its surface roughness is reduced. Mechanical polishing method has the advantages of simple operation and low cost, but the polishing process is easy to produce scratches and surface damage, and the polishing effect is affected by the quality of the polishing wheel, polishing liquid and polishing cloth.
- Chemical polishing
Chemical polishing is the use of chemical reactions to remove the surface layer of the metal grid, so as to achieve the purpose of polishing. This method has the advantages of fast polishing speed, good surface quality, but the need for different metal materials to choose the appropriate polishing fluid, and may cause pollution to the environment.
- Electrochemical polishing
Electrochemical polishing is in the electrolyte solution, through the role of the current to make the metal grid surface electrochemical reaction, so as to remove the surface roughness layer. Electrochemical polishing method has the advantages of good polishing effect and controllability, which is suitable for mass production. However, electrochemical polishing on the power supply, electrolyte and polishing parameters of the higher requirements, the cost is relatively high.
- Laser polishing
Laser polishing is the use of high-energy laser beams on the surface of the metal grid for instantaneous heating, so that the surface material evaporation, melting or ablation, so as to achieve polishing. Laser polishing method has the advantages of high processing accuracy, speed, controllability, etc., suitable for high-precision requirements of the metal grid polishing. However, the laser polishing equipment cost is higher, the operator’s requirements are also higher.
- ultrasonic polishing
Ultrasonic polishing is the use of ultrasonic vibration on the metal grid surface friction, so as to achieve the effect of polishing. Ultrasonic polishing method has the advantages of fast polishing speed, good surface quality, environmentally friendly and so on. However, the cost of ultrasonic polishing equipment is high, and there are certain requirements for the thickness and strength of the metal grid.
Third, the application of metal grid polishing method
Metal mesh polishing method has a wide range of practical applications, such as in the field of electronics, polished metal mesh can be used in circuit boards, heat sinks, etc.; in the optical field, polished metal mesh can be used for optical instruments, mirrors, etc.; in the field of precision instruments, polished metal mesh can be used for sensors, strain gauges, etc.. Therefore, the research and application of metal grid polishing method is of great significance to promote the development of related fields.
In conclusion, the research and application of metal mesh polishing method is an important topic in the field of metal mesh manufacturing. In the actual production process, suitable polishing methods can be selected according to the application areas and surface quality requirements of metal meshes. With the continuous development of science and technology, it is believed that metal mesh polishing methods will be further optimized to provide more support for the development of related fields.
