Recently, Fujian Yuanxiang New Materials Co., Ltd. obtained a patent for a precipitation method silica reaction cooling device, marking an important breakthrough in the production technology of precipitated silica in China. This patent effectively solves the problems of particle aggregation and uneven particle size distribution in traditional processes by optimizing temperature control and crystal structure regulation during the reaction process, providing higher quality raw materials for the high-end rubber, coating, and cosmetics industries.
As a key inorganic material, precipitated silica is widely used in fields such as tire reinforcement, toothpaste friction agents, and coating thickeners. However, in traditional production processes, fluctuations in reaction temperature can easily lead to unstable particle structure, affecting product performance. The patented device of Yuanxiang New Materials introduces gas into the reaction system to form microbubbles through the synergistic effect of high-pressure Roots blower and aeration device, which not only achieves efficient cooling, but also suppresses particle aggregation through the physical separation effect of bubbles, making the product particle size distribution more uniform and the specific surface area more controllable. Experimental data shows that the use of this technology to produce silica improves rubber reinforcement performance by more than 15%, while significantly improving the rheological properties of coatings and the friction effect of toothpaste.
This technological breakthrough has profound implications for the industry. On the one hand, China's production capacity of precipitated silica accounts for over 90% of the global total, but high-end products have long relied on imports. The innovative device of Yuanxiang New Materials provides technical support for domestic silicon dioxide to enter the high-end market, which is expected to break the monopoly of international giants in the field of gas-phase silicon dioxide. On the other hand, with the rapid development of industries such as green tires and environmentally friendly coatings, the demand for high-performance silica in the market continues to grow. The application of this patented technology will promote the upgrading of the industrial chain towards high added value and help enterprises seize market opportunities.
Industry experts point out that the patent of Yuanxiang New Materials is not only a single technological breakthrough, but also reflects China's strategic transformation from "scale expansion" to "quality improvement" in the field of inorganic materials. In the future, as more companies increase their R&D investment, the precipitated silica industry is expected to achieve wider applications in emerging fields such as new energy vehicles and 5G materials.
