What are the differences in applicability of Dalian sandblasting processing to different materials?

Dalian sandblasting is a very common and effective surface treatment process. It can change the surface morphology and performance of the workpiece, making it more beautiful and durable. In order to achieve good processing results, we need to pay attention to the selection of sand particles and the safety of operation. We hope that through our efforts, sandblasting processing technology can be further developed and applied.

Sandblasting has many advantages. Sandblasting can clean the surface, remove dirt and deposits such as rust, paint, etc., and give the surface a brand new look. Secondly, sandblasting can improve surface quality, remove surface defects, burrs, etc., and enhance product quality and service life. Again, sandblasting can increase the roughness of materials, provide better adhesion, and facilitate painting and coating construction. In addition, sandblasting can also repair and repair the surface of components, restoring their functionality and aesthetics.

What are the differences in applicability of Dalian sandblasting processing to different materials?

Workpieces of different materials will experience different impact forces during sandblasting processing. For example, metal materials generally have high hardness and strength, so when undergoing sandblasting processing, the impact force of abrasives needs to be relatively large to play a grinding role. For some softer materials, such as plastics, due to their lower hardness, the required impact force is relatively small. Therefore, when carrying out sandblasting processing, it is necessary to choose the working pressure of the sandblasting machine and the type of abrasive based on the hardness of the material to ensure that the workpiece can obtain appropriate grinding effects.

Secondly, the degree of damage to workpieces made of different materials during sandblasting may also vary. Some brittle materials, such as ceramics, are prone to cracking and fracture when subjected to excessive impact force, leading to the failure of the workpiece. Therefore, when conducting sandblasting, it is necessary to evaluate the brittleness of the workpiece and choose appropriate sandblasting conditions to avoid irreparable damage to the workpiece. In addition, some materials that are prone to corrosion, such as iron, aluminum, and other metals, are prone to oxidation and corrosion due to their potential exposure to air during sandblasting. Therefore, during sandblasting, it is necessary to perform anti-corrosion treatment on these materials to extend the service life of the workpiece.

Again, the surface quality of workpieces made of different materials will also vary after sandblasting. During sandblasting, the grinding effect of abrasives on the surface of the workpiece can lead to an increase in surface roughness. For some workpieces that require a smooth surface, such as mirrors and optical components, sandblasting may make their surfaces rough, thereby affecting their optical performance. Therefore, for these materials, sandblasting usually requires subsequent polishing and polishing treatments to achieve the desired surface quality.

The main function of sandblasting is to change the surface morphology and properties of the workpiece. On metal materials, sandblasting can remove oxide skin at welding points, evenly distribute surface color differences, increase surface smoothness and accuracy. On plastic products, sandblasting can increase their surface roughness, making them easy to apply and adhere. On ceramic products, sandblasting can polish the surface, increase smoothness and tactile sensation. In addition, sandblasting can also change the color of materials, making them more personalized and aesthetically pleasing.
