4, the technical level of the industry
Since 2008, China's sedimentary silica industry has followed the three concepts of scientific development concept, brand-name product strategy and circular economy proposed by the state, and has determined the direction of product innovation, energy conservation and emission reduction, safety and environmental protection, and formulated with reference to international standards. Industry standards and national standards.

(1) From the perspective of the industry as a whole, there is a certain gap between the overall level and technical level of China's precipitation white carbon black products and the international industry. Foreign well-known white carbon multinational companies, such as Degussa of Germany, Solvay of Belgium and PPG of the United States, have their own research and development institutions, engaged in the development of new products, new technologies and new application fields; More, can meet the different needs of users; the raw materials used, production technology, testing methods, product quality stability, grades and other aspects have considerable advantages. Although domestic enterprises have a certain scale of production, their independent innovation capability is weak. Most enterprises have unreasonable product structure, single varieties, and low added value of products. Although China is a net exporter of white carbon black and the world's first output of white carbon black, high-dispersion white carbon black, nano-level matting agent, high-grade white carbon black for silicon rubber, white carbon black for battery separator and others The use of special-purpose white carbon blacks is still in existence.

(2) From the local field, some advantageous enterprises in China have researched and developed high-tech products with independent intellectual property rights through their own technologies, in terms of technology, technology, production equipment, testing equipment, product quality, selection of raw materials, etc. It has reached the advanced level of the international industry; its high-dispersion white carbon black, nano-scale silica matting agent, high-grade white carbon black special products for silicone rubber have reached the international level of similar products. Highly dispersed white carbon black is used in the tread rubber of tires, which plays a good grip, safe and non-slip, reduces rolling resistance, reduces fuel consumption, reduces exhaust gas emissions, and achieves a relatively high level of quality; In recent years, the technical level of black has been significantly improved, and all or part of the imported white carbon black has been replaced.
