How to prevent material deformation or discoloration during Dalian sandblasting processing?

Dalian sandblasting, as a commonly used surface treatment technology, has a wide range of applications in multiple industries. It can improve the roughness and smoothness of the workpiece surface, remove surface oxides and stains, enhance adhesion, and enhance decorative effects. However, sandblasting processing also requires attention to issues such as dust pollution and subsequent treatment to ensure processing effectiveness and operational safety. However, with the continuous progress of technology and the emergence of new materials, sandblasting processing will continue to be optimized and improved, providing more efficient and environmentally friendly surface treatment solutions for various industries.

The basic steps of sandblasting are as follows: Install the workpiece to be processed on the workbench of the sandblasting machine. Then, load the abrasive into the sandblasting gun of the sandblasting machine and adjust the sandblasting pressure and angle of the sandblasting machine. Next, turn on the power of the sandblasting machine, spray the abrasive onto the surface of the workpiece, and sandblasting with uniform force until satisfactory results are achieved. Turn off the power of the sandblasting machine, remove the processed workpiece, and carry out subsequent cleaning and treatment.

How to prevent material deformation or discoloration during Dalian sandblasting processing?

Choosing the appropriate sandblasting material is very important. Different types of materials have different reactions to sandblasting. Some materials may be relatively fragile and prone to deformation or fracture, while others may be relatively resistant to sandblasting treatment. Therefore, when selecting sandblasting materials, it is necessary to make reasonable choices based on specific material characteristics to prevent deformation and discoloration.

Secondly, controlling the sandblasting pressure and time is also very important. Excessive sandblasting pressure or time may cause excessive surface temperature of the material, resulting in deformation or discoloration issues. Therefore, in the sandblasting process, it is necessary to control the sandblasting pressure and time based on the properties and thickness of the material to prevent problems from occurring due to material overheating.

In addition, special attention should also be paid to the sandblasting materials used during the sandblasting process. The particle size and shape of sandblasting materials have a significant impact on the treatment effect. Sand blasting materials that are too thick or too sharp may cause excessive scratching of the material surface, resulting in deformation or discoloration. Therefore, in sandblasting processing, it is necessary to select appropriate sandblasting materials to ensure that their particles are fine and have a rounded shape, in order to reduce damage to the material surface.

In addition, surface preparation before sandblasting is also very important. Before sandblasting, it is necessary to thoroughly clean and degrease the material to ensure the sandblasting effect and surface quality of the material. If there are substances such as grease, dirt, or oxides on the surface, it may cause discoloration or deformation of the material after sandblasting. Therefore, appropriate surface treatment is required before sandblasting to ensure the cleanliness and smoothness of the material surface.

Sandblasting has the following main advantages. Sand blasting can improve surface roughness and smoothness while maintaining accurate workpiece size, providing a good decorative effect. Secondly, sandblasting can remove oxides, corrosives, and stains on the surface of the workpiece, improving its cleanliness. Once again, sandblasting can enhance the adhesion of the workpiece surface and improve the adhesion between the workpiece and the coating. In addition, sandblasting can also repair damaged workpiece surfaces, remove scratches and dents, and restore the original appearance and function of the workpiece.
