The surface roughness of rubber products has an effect on the sealing property, friction property, wear resistance and appearance quality. Here are the specific impacts:
1. Sealing performance: The smaller the surface roughness of rubber products, the larger the contact area between rubber products and sealing surface, the better the sealing performance. Conversely, the greater the surface roughness, the smaller the contact area, and the worse the sealing performance.
2. Frictional properties: The surface roughness of rubber products has an impact on the frictional properties. The smaller the surface roughness, the smaller the friction coefficient, and the greater the vice versa. Therefore, in some cases where friction needs to be reduced, rubber products with smaller surface roughness need to be selected.
3. Wear resistance: The surface roughness of rubber products also has an impact on wear resistance. The smaller the surface roughness, the better the wear resistance of rubber products, and the worse the vice versa. Therefore, in some occasions that require better wear resistance, rubber products with smaller surface roughness need to be selected.
4. Appearance quality: The rubber products with rough surface may have problems such as mantle, incomplete surface, damage, protruding, cracking of the mold line, spitting white, spitting colorful, etc., which affects its beauty and quality. The smaller the surface roughness, the better the appearance quality of rubber products, and the worse the vice versa. Therefore, in some cases with higher requirements for appearance quality, rubber products with smaller surface roughness need to be selected.
In summary, the roughness of rubber products has an important impact on the performance and appearance, and it is necessary to choose the appropriate roughness according to the actual use needs.
