Recently, with the continuous advancement of normalized environmental protection supervision in the domestic chemical industry and the continuous upgrading of refined production emission standards, the silica industry has ushered in a new round of supply-side adjustment. In the past, there were many small and medium-sized workshop-style production lines in the industry, the energy consumption of traditional wet processes was high, the treatment of wastewater and waste gas was difficult, and the extensive production mode was difficult to adapt to the current requirements of green chemical development.
Under the constraints of strict environmental protection policies, many silica production enterprises have accelerated the technical transformation and upgrading of production lines, carried out technological transformation around water recycling, exhaust gas desulfurization and purification, and comprehensive utilization of solid waste, optimized the production process, and reduced pollutant emissions in the production process. At the same time, the company gradually improves the raw material ratio and reaction process, reduces the consumption of chemical auxiliary materials under the premise of ensuring the basic performance of products, realizes low-carbon and clean production, and greatly improves the overall production standardization.
The internal pattern of the industry has also changed significantly, with weak anti-risk capabilities, substandard environmental protection, and old equipment gradually withdrawing from the market, and industry resources continuing to be concentrated in leading enterprises with large-scale production, improving environmental protection support, and stable quality control capabilities, and the phenomenon of homogeneous and low-price competition in the market has been effectively alleviated.
In addition to the optimization of the production side, the downstream fine chemical field has become more and more stringent on the purity, dispersion, impurity content and other indicators of silica products, promoting enterprises to continuously refine product classification, develop special specification products for coatings, inks, adhesives, daily chemical fillers and other subdivisions, and get rid of the dependence on a single low-end general product. Relying on quality upgrading and supply structure optimization, the overall development quality of the domestic silica industry continues to improve, and the development of the industrial chain is more healthy and stable.
Industry experts said that the follow-up environmental protection standards will remain strict for a long time, and the integration of industry capacity will continue. Relying on process upgrading, green production, and refined product development will become the core competitiveness of silica enterprises, and the industry as a whole will bid farewell to the era of extensive expansion and develop steadily towards standardization, refinement and high quality.
