In June 2025, Anhui Xinna Zhengsheng New Materials Co., Ltd. sparked a wave of technological innovation in the industry with its independently developed patent for "white carbon black preparation device and preparation process". This patent solves the technical bottleneck of low purification efficiency and substandard purity in traditional processes by optimizing the three core processes of magnetic separation, chemical cleaning, and separation.
The innovative design of this device is reflected in three major modules: the magnetic separation section adopts a real-time monitoring system, which automatically adjusts the powder conveying structure through the magnetic separation area status monitoring module, ensuring that the impurity separation rate reaches over 99%; The chemical cleaning department introduces a particle mixing structure and a cleaning status monitoring module to dynamically control the concentration and temperature of the cleaning solution, significantly reducing chemical residues; The separation section improves the particle size uniformity of the product to within ± 0.5 microns by combining a circular sieve and a filter screen. According to experimental data, the white carbon black prepared by the new process improves key indicators such as rubber reinforcement performance and coating coverage by 15% -20% compared to traditional products, and reduces production costs by about 12%.
Industry experts point out that as a key reinforcing agent in the fields of tires, silicone rubber, coatings, etc., the purity and dispersibility of white carbon black directly affect the performance of end products. Taking green tires as an example, highly dispersed white carbon black can reduce rolling resistance by 10% -15% and significantly improve fuel economy. This technological breakthrough not only meets the demand for high-end materials in the "14th Five Year Plan" for the rubber industry, but also provides a path for domestic enterprises to break through international technological barriers.
Anhui Xinna Zhengsheng New Materials Co., Ltd. was established in 2009 with a registered capital of 50 million yuan, specializing in the field of non-metallic mineral products. The company has applied for a total of 71 patents and participated in the formulation of 3 industry standards. Its products are widely used in enterprises such as Shandong Linglong Tire and Fujian Zhengxin Tire. With the promotion of new technology mass production, it is expected that an annual production capacity of 20000 tons will be added in the second half of 2025, driving the coordinated upgrading of the regional industrial chain.
