The production process of white carbon black is mainly divided into precipitation method and gas-phase method, and environmental pressure drives technological iteration:
Optimization of precipitation method: Using biomass materials such as rice husk ash and diatomaceous earth to replace sulfuric acid and reduce waste acid emissions.
Gas phase method innovation: By recycling the by-product hydrogen chloride, closed-loop production is achieved.
Nano modification: Surface grafting of polymer chains to enhance dispersibility and functionality.
Trend: The integration of green chemistry and intelligent manufacturing, such as continuous reactors and AI process optimization systems, will reduce energy consumption by more than 30%.
