A disperser is a device that forms a uniform mixture of solid materials or fluids under the action of a high-speed rotating rotor. It generates high tangential velocity and high-frequency mechanical effects through the high-speed rotating rotor, subjecting materials to strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact tearing, and turbulence in the narrow gap between the stator and rotor, ultimately achieving uniform dispersion. Dispersants are widely used in various industries such as coatings, inks, pigments, chemicals, pharmaceuticals, and food. For example, its applications in cosmetics mainly include the preparation of lotion, cream, powders and creams. The disperser can efficiently mix and disperse different ingredients, ensuring a uniform and delicate texture of the product, and improving its stability and effectiveness. The laboratory disperser is suitable for testing the performance of a small amount of lotion to pave the way for mass industrial production.
