Due to this special physical and chemical structure, the common silica particles are prone to produce a large number of adsorbed water molecules on the surface, secondary aggregation between molecules and excessive specific surface area when forming aggregates, which affect the effect of its industrial application. The specific performance is as follows: the surface is hydrophilic
Because the surface of white carbon black aggregate contains a large number of polar hydroxyl groups, it will have a strong adsorption effect on the outside water molecules, so that a large number of water molecules are adsorbed on its surface. During the processing of rubber products, a large number of water molecules adsorbed on the surface of white carbon black particles will make the mixture colloid appear bubbles and holes in the vulcanization of the mixture, thus affecting the performance of the colloid. At the same time, the surface of rubber products generally does not have polarity, while the surface of silica contains a large number of polar hydroxyl groups, resulting in poor compatibility between the two, thus affecting the reinforcing effect of silica.
