Recently, a green production process for silica matting agents has been fully put into operation. Jointly developed by domestic research institutions and industrial players, the core of this process is to build a closed-loop system of "raw materials - production - waste - reuse". In the traditional precipitation method for producing silica matting agents, a large amount of silicon-containing wastewater and exhaust gas are generated. The new process adopts membrane separation technology to recover silicon resources from wastewater, with the recovery rate increased to over 95%. Meanwhile, it is equipped with exhaust gas purification and waste heat recovery devices, reducing production energy consumption by 30% and carbon emission intensity by 28%, which is far superior to the industry average.

In terms of product quality, the silica matting agents prepared by the new process have a more uniform particle size distribution, with matting efficiency 10%-15% higher than that of traditional products. Moreover, they have higher surface activity and significantly enhanced compatibility with water-based coatings and solvent-free coatings, perfectly meeting the requirements of downstream environmentally friendly coating systems. At present, the process has been verified on multiple production lines, and the products have been successfully supplied to fields with strict environmental requirements such as exterior wall coatings and children's toy coatings.

Industry data shows that the domestic silica matting agent industry currently faces problems such as a high proportion of small and medium-sized production capacity and backward environmental protection facilities. The implementation of this green process provides a replicable model for the upgrading of backward production capacity in the industry. At the policy level, with the advancement of the "dual carbon" goals and the increase in the intensity of environmental tax collection, green production capacity has become the core competitiveness of enterprises. Industry insiders predict that in the next three years, the market share of silica matting agents adopting green processes will exceed 60%, driving the overall carbon footprint of the industry down by more than 15%.

Experts said that the breakthrough of green production processes is not only a technological upgrade, but also a transformation of the industry's development concept. In the future, combined with intelligent production control and biomass raw material substitution technology, the silica matting agent industry will further achieve the dual goals of "low carbon" and "high efficiency", providing material support for the green transformation of downstream manufacturing industries.
