Roller Surface Sandblasting Further Strengthened

As a key component in conveying system, the performance of rollers directly affects the efficiency and stability of the whole conveying system. In the long-term use process, the surface of the roller is prone to wear and corrosion, which affects its normal function. In order to improve the wear resistance of rollers and prolong their service life, sandblasting technology has become an effective surface treatment method.

Sandblasting is a kind of surface treatment technology that spraying abrasive (such as steel sand, ceramic beads, emery, etc.) to the surface of the workpiece at a high speed to remove the surface corrosion, oxidation layer, paint layer, etc., while forming a rough and clean surface and improving the hardness and wear resistance of the material surface. Sandblasting can not only provide a good foundation for subsequent surface treatment such as coating and electroplating, but also improve its fatigue resistance and corrosion resistance by changing the microstructure of the material surface. The main features of sandblasting on the surface of the roller are as follows:

1. Improve surface hardness and wear resistance: In the process of sandblasting, the impact of abrasive can produce cold hardening effect on the surface of the roller, thereby improving surface hardness and enhancing wear resistance.

2. Enhance the adhesion of the coating: the surface after sandblasting is rougher, which can significantly improve the adhesion of the subsequent coating and extend the service life of the coating.

3. Improve fatigue resistance: Through sandblasting, residual compressive stress can be generated on the surface of the roller, thereby improving its fatigue resistance and prolonging its service life.

4. Remove surface defects: sand blasting can effectively remove the rust, oxide layer and other defects on the surface of the roller, providing a clean and smooth surface for subsequent processing and use.

5. Environmental protection: Compared with traditional chemical cleaning methods, sandblasting enhancement technology is more environmentally friendly, reducing the use of chemical substances and emissions.

Sand blasting technology provides an effective method for surface treatment of idlers, which can significantly extend the service life of idlers and improve the operating efficiency and stability of conveying system by improving wear resistance, corrosion resistance and coating adhesion. With the continuous progress of technology, the application prospect of sandblasting in roller surface treatment will be more broad.
