The development process of white carbon black
The development process of white carbon black can be traced back to a long time ago. With the advancement of technology and the deepening of people's understanding of the properties of white carbon black, its preparation methods are constantly improved and optimized. Initially, white carbon black was mainly prepared by traditional precipitation method, using sulfuric acid, hydrochloric acid, CO2, and water glass as the basic raw materials to produce silicon dioxide. Later, with the rise of nanotechnology, gas-phase white carbon black gradually emerged. The preparation process of gas-phase white carbon black is complex, but the product has high purity, small particle size, and excellent performance. In recent years, with the increasing awareness of environmental protection and the demand for sustainable development, people have begun to explore new methods for preparing white carbon black using non-metallic minerals and their extensions as silicon sources, in order to reduce production costs and minimize environmental pollution. This development process demonstrates the continuous progress and innovation of white carbon black preparation technology.

The specific application of white carbon black in the rubber industry
White carbon black plays an important role as a reinforcing agent in the rubber industry. It can greatly improve the strength, wear resistance and aging resistance of rubber products. Meanwhile, white carbon black can also improve the processing performance of rubber and reduce production costs. White carbon black is particularly widely used in tire manufacturing. It can increase tire grip and improve driving safety. In addition, white carbon black can reduce the hysteresis of the rubber material, lower the rolling resistance of the tire, and thus save fuel consumption. White carbon black is widely used as the main reinforcing filler in the sole production materials of high-end leather shoes and sports shoes, which can improve the wear resistance, hardness, tensile strength, and tear strength of the sole.
