Abstract: This article mainly conducts a comparative analysis of the effects of chrome plating polishing and magnetic polishing machines on metal surface treatment, discusses the advantages and disadvantages of the two polishing methods, and provides reference for enterprises when choosing polishing processes.
1. Introduction
In the production process of metal products, surface treatment is an important process link. As a method of surface treatment, polishing can make the metal surface smooth and beautiful, and improve the quality and grade of the product. Currently, common polishing methods on the market include chrome plating polishing and magnetic polishing machine polishing. This article will conduct a comparative analysis of the effects of these two polishing methods to help companies choose the appropriate polishing process.
2. Chrome plating and polishing
1. Principle: Chromium plating polishing uses the principle of electroplating to deposit a layer of chromium on the metal surface, thereby improving the hardness and wear resistance of the metal surface. The chromium plating layer has excellent corrosion resistance, wear resistance and smooth finish.
2. Advantages:
(1) High surface finish: The chrome plating layer has a smooth surface and good gloss, which can significantly improve the appearance quality of the product.
(2) Wear resistance and corrosion resistance: The chromium layer has high hardness and wear resistance and can effectively resist corrosion from the external environment.
(3) Mature technology: Chromium plating and polishing technology has been developed in my country for many years. The technology is mature and easy to operate.
3. Shortcomings:
(1) Environmental pollution: The waste water and exhaust gas generated during the chromium plating process contain harmful substances and cause pollution to the environment.
(2) Higher cost: chrome plating equipment requires large investments and high operating costs.
(3) The problem of chromium layer peeling off: Under certain conditions, the chromium layer is prone to peeling off, affecting product quality.
3. Magnetic polishing machine
1. Principle: The magnetic polishing machine uses a magnetic field to guide the magnetic abrasives, causing the abrasives to rub against the metal surface at high speed to achieve the polishing effect.
2. Advantages:
(1) Environmental protection: The magnetic polishing machine uses water-based abrasives, which is pollution-free and complies with the national environmental protection policy.
(2) High efficiency: The magnetic polishing machine has fast polishing speed, high efficiency and saves labor costs.
(3) Strong adaptability: suitable for polishing metal products of various shapes and sizes.
(4) Uniform polishing: The abrasives under the action of the magnetic field can be evenly distributed on the metal surface, and the polishing effect is consistent.
3. Shortcomings:
(1) Low polishing accuracy: Compared with chrome plating polishing, the magnetic polishing machine is slightly insufficient in polishing accuracy.
(2) Abrasive loss: Magnetic abrasives are lost during use and need to be replaced regularly.
4. Comparative analysis
1. Environmental protection: The magnetic polishing machine is obviously better than chrome plating polishing and complies with my country’s environmental protection policy.
2. Cost: The initial investment of magnetic polishing machine is low, and the operating cost is relatively low.
3. Polishing effect: Chrome polishing is better than magnetic polishing machine in terms of smoothness and wear resistance, but it is slightly inferior in terms of adaptability and uniformity.
4. Application scope: Magnetic polishing machine is suitable for polishing various metal products, while chrome plating polishing is mainly used for specific occasions.
5. Conclusion
To sum up, chrome plating polishing and magnetic polishing machines each have their own advantages and disadvantages. When companies choose polishing processes, they should comprehensively consider their own product characteristics, production costs and environmental protection requirements. In the context of increasingly strict environmental protection policies, magnetic polishing machines have broader development prospects.
