Among metal processing hardware parts, there are significant differences between chemical polishing and mechanical polishing of Brass plate.
Chemical polishing mainly uses chemical solutions to react chemically with the Brass plate surface to achieve the purpose of making the surface smooth and flat. Usually, the solution used in chemical polishing contains acidic or alkaline ingredients, which can dissolve the microscopic raised parts on the surface of the Brass plate and make the surface smoother. The advantage of chemical polishing is that it can quickly process large-area Brass plates, and can obtain very high gloss, showing a mirror-like effect. In addition, for some Brass plate parts with complex shapes, chemical polishing can be applied to various parts evenly without being limited by the shape of the part. However, chemical polishing also has some disadvantages. First of all, chemical polishing requires the use of specific chemical solutions. These solutions are usually corrosive and dangerous to a certain extent, and require strict control of operating conditions and safety protection. Secondly, the chemical polishing process is difficult to control accurately, and over-polishing or uneven polishing is prone to occur, thus affecting the surface quality. Moreover, chemical polishing may have a certain impact on the size of the Brass plate because a small amount of material is removed during the chemical reaction.
In contrast, mechanical polishing removes uneven parts of the Brass plate surface through physical friction. Polishing wheels, sandpaper and other tools are usually used to polish the Brass plate surface under a certain pressure and speed. The advantage of mechanical polishing is that the operation is relatively simple and it is easy to control the degree and effect of polishing. Polishing materials of different particle sizes can be selected according to different needs to gradually improve the smoothness of the surface. At the same time, mechanical polishing has less impact on the size of the Brass plate and can better maintain the original dimensional accuracy of the part. However, mechanical polishing also has its limitations. For Brass plate parts with complex shapes, mechanical polishing may be difficult to reach some narrow parts and corners, resulting in uneven polishing. In addition, the efficiency of mechanical polishing is relatively low, especially for large-area Brass plates, which requires a long time and manpower.
In summary, there are obvious differences between chemical polishing and mechanical polishing of Brass plate in terms of principles, effects and scope of application. In practical applications, it is necessary to select the appropriate polishing method according to the specific processing requirements and part characteristics to obtain the best surface quality and processing effect.
