Sunfactant-D009 is a viscosity-reducing wetting dispersant that helps lower the viscosity of the precursor slurry and significantly improves grinding efficiency
Increases the precursor solid content by 10%~15%, reducing spray-drying energy consumption |
Lowers the viscosity of high-solid-content slurry, improving grinding efficiency while enhancing slurry pumpability |
Reduces grinding time and increases grinding efficiency |
Facilitates the nanonization of precursor particles, enabling material particle size reduction to the nanoscale |
