From Laboratory to Industry: Breakthrough in Large Scale Production Technology of Precipitation Method White Carbon Black

As an important material in the industrial field, the large-scale production technology of precipitated white carbon black directly affects cost and performance. This article focuses on the process bottlenecks of the traditional water glass sulfuric acid precipitation method, such as reaction temperature control, particle size uniformity, and high energy consumption. By introducing the technology of high gravity reactor, the traditional sedimentation time was shortened from several hours to minutes, and the pore structure was optimized by the sol-gel method, so that the specific surface area was increased to more than 400m ²/g. The case analysis shows that an enterprise has successfully applied to high-end tire manufacturing by transforming the production line and adopting the continuous neutralization reaction and spray drying process, with single line capacity increased by 300%, energy consumption reduced by 45%, and product purity reached 95%. Technological breakthroughs not only reduce production costs, but also promote the application of white carbon black in emerging fields such as new energy battery separators and environmentally friendly adsorbents.
