High-Shear Disperser

The high-shear disperser generates shear force through the high-speed rotation of the rotor, subjecting materials to intense mechanical action in narrow gaps, achieving particle fragmentation and uniform mixing. It is used for powder wetting, agglomerate dispersion, and emulsion preparation in industries such as coatings and inks.
Selection
Select the power range based on material viscosity, determine the volume specification according to processing capacity, choose the corresponding motor considering explosion-proof requirements, confirm the cooling method based on process temperature, and select corrosion-resistant material structures for corrosive media.

Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
