1. The influence on the dispersion of the filler The finely divided filler can be evenly distributed in the plastic material, and the dispersion is better, so that the color uniformity of the rubber compound, the strength, toughness, fatigue resistance and other comprehensive machinery of the rubber compound Performance has been improved.
2. Effect on oil absorption value The fineness of the filler is high, the specific surface area is large, and the oil absorption value will increase accordingly. The greater the oil absorption value, the greater the light absorption of the compound, and the surface of the product will appear sub-surface or matte. If the oil absorption is small, the light absorption is small, and the surface of the product will appear bright.
3. The impact on the production of rubber compound The fineness of the filler is high, the friction coefficient in the rubber compound granulation process will be small, making the plastic granulation ability strong, and the plastic product surface is smooth, the molding ability will also be strengthened. However, due to the adsorption force between molecules, high-fineness fillers are prone to agglomeration, and the reverse side will reduce the uniformity of the fillers and the overall mechanical properties.
