The wear resistance of fluorosilicone (fluorosilicone rubber) is relatively general, but its wear resistance can be significantly improved through appropriate surface treatment technology. The following is a detailed analysis of the wear resistance and surface treatment technology of fluorosilicone:


1. Wear resistance of fluorosilicone
The wear resistance of fluorosilicone is affected by many factors such as its molecular structure, hardness, cross-linking density, etc. Although fluorosilicone has excellent oil resistance, solvent resistance, high and low temperature resistance and other properties, its wear resistance is relatively poor. This is mainly because the molecular chain of fluorosilicone has good flexibility and is easily worn by external forces. Therefore, in some occasions where high wear resistance is required, fluorosilicone may not be the best choice.

2. Surface treatment technology of fluorosilicone
In order to improve the wear resistance of fluorosilicone, a variety of surface treatment technologies can be used. These technologies mainly improve its wear resistance, hardness and tear resistance by changing the microstructure and chemical composition of the surface of fluorosilicone.

Sandblasting:
Sandblasting is the process of impacting and cutting the surface of fluorosilicone by high-pressure jetting of sand particles to remove surface dirt, increase surface roughness and improve adhesion. This treatment method can significantly improve the bonding between fluorosilicone and the coating or adhesive, thereby improving wear resistance.
Chemical etching:
Chemical etching is the use of chemical reactions to remove a layer of material on the surface of fluorosilicone to form a specific microstructure. This treatment method can increase the surface roughness and specific surface area, thereby improving wear resistance and wettability. However, chemical etching requires precise control of reaction conditions and time to avoid excessive damage to the fluorosilicone matrix.
Plasma treatment:
Plasma treatment is the use of low-temperature plasma to modify the surface of fluorosilicone. The high-energy particles in the plasma can react chemically with the surface of fluorosilicone to generate active groups and change the surface polarity. This treatment method can significantly improve the hydrophilicity and adhesion of the fluorosilicone surface, thereby improving wear resistance. In addition, plasma treatment can also increase the surface roughness and microporous structure, further improving wear resistance.
Coating treatment:
Coating a wear-resistant coating on the surface of fluorosilicone is also an effective way to improve its wear resistance. Wear-resistant coatings usually have the characteristics of high hardness, high wear resistance and good chemical stability. By selecting appropriate coating materials and coating processes, the wear resistance and service life of fluorosilicone can be significantly improved.

3. The influence of surface treatment technology on the wear resistance of fluorosilicone
After adopting the above surface treatment technology, the wear resistance of fluorosilicone can be significantly improved. Specifically:
Sandblasting can increase the roughness and adhesion of the fluorosilicone surface, thereby improving the wear resistance;
Chemical etching can change the microstructure and chemical composition of the fluorosilicone surface, increase wear resistance and wettability;
Plasma treatment can significantly improve the hydrophilicity and adhesion of the fluorosilicone surface, and increase the surface roughness and microporous structure;
Coating treatment can form a layer of high hardness and high wear resistance on the surface of fluorosilicone, thereby improving wear resistance and service life.

In summary, although the wear resistance of fluorosilicone is relatively poor, its wear resistance can be significantly improved by appropriate surface treatment technology. These treatment technologies include sandblasting, chemical etching, plasma treatment and coating treatment. In practical applications, appropriate treatment methods can be selected according to specific needs and conditions to improve the wear resistance of fluorosilicone.
