What are the considerations for selecting sandblasting materials in Dalian?

Dalian sandblasting is an efficient method for rust removal and scaling. For steel products, whether it is the oxide scale generated during the production process or the rust that appears during use, sandblasting can quickly and effectively remove it. For example, in the processing of materials such as steel bars and steel plates used in construction, sandblasting can clean the surface rust and oxide scale, improving the quality and service life of the steel.

Sandblasting processing has a wide range of applications in metal surface treatment. It can remove oxides, dirt, and scratches from metal surfaces, resulting in a clean and smooth treatment of the metal surface. Secondly, sandblasting can increase the roughness and surface adhesion of metal surfaces, improving their corrosion resistance and wear resistance. In addition, sandblasting can also achieve different processing effects by changing the spraying speed and angle of sand particles, such as surface mirror treatment, carving processing, etc.

What are the considerations for selecting sandblasting materials in Dalian?

What needs to be considered is the hardness of the material. Materials with higher hardness can better resist the impact and wear caused by sandblasting, so when choosing sandblasting materials, materials with higher hardness should be prioritized. The commonly used sandblasting materials include alumina, fiberglass, ceramics, etc.

Secondly, the density of the material needs to be considered. Materials with higher density can obtain higher impact energy during sandblasting, thereby better removing surface dirt and oxide layers. Therefore, materials with higher density are more suitable as sandblasting materials. Common sandblasting materials with high density include diamond, alloys, etc.

In addition, the corrosion resistance of the material should also be considered. In sandblasting, materials may come into contact with media with strong chemical properties. If the material does not have sufficient corrosion resistance, it may be damaged during the sandblasting process. Therefore, when selecting sandblasting materials, the corrosion resistance of the materials should be considered.

Consider the cost and availability of materials. Although some high-performance materials perform very well in sandblasting, their cost may also be high and their usability may be low. When selecting sandblasting materials in practice, it is necessary to comprehensively consider the performance, cost, and availability of the materials.

Sandblasting processing is a widely used method in metal surface treatment and carving processing. It uses high-speed jet airflow with sand particles to impact the metal surface, forming a certain shape and texture on the metal surface, achieving the effect of removing surface oxides, dirt, and scratches, while also improving the roughness of the metal surface and increasing surface adhesion.

Surface roughness is an important quality indicator for sandblasting processing. By selecting appropriate parameters such as abrasive particle size, sandblasting pressure, distance, and angle, the surface roughness of the workpiece can be controlled. In practical operation, a surface roughness meter can be used to measure the surface of the workpiece. For different application scenarios, there are different requirements for surface roughness. For example, in sandblasting preparation for subsequent coatings, the surface roughness is generally required to be between Ra1.6-Ra6.3 μ m.
