Overview of the working process of paint and coating equipment
◆Under the high-speed drive of the motor, the processed material is sucked into the working chamber.
◆The strong centrifugal force throws the material radially into the narrow and precise gap between the stator and rotor. Simultaneously subjected to centrifugal compression, impact and other forces, the material is initially dispersed and emulsified.
◆Under the action of a large linear velocity of 15m/s generated at the outer end of the high-speed rotating rotor, strong hydraulic shear, centrifugal friction, tearing and collision are formed, allowing the material to be fully dispersed, emulsified, homogenized, and broken, while being ejected through the stator slot.
◆The material is continuously ejected from the radial direction at high speed, changing its flow direction under the resistance of the material itself and the container wall. At the same time, under the action of the upper and lower axial suction forces generated in the rotor area, a three-dimensional turbulent flow is formed. The material undergoes several cycles and ultimately completes the dispersion and emulsification process.
Overview of the working principle of paint and coating equipment
High shear dispersion emulsification refers to the efficient, fast, and uniform distribution of one or more phases into another continuous phase, where the phases are usually incompatible with each other. Due to the strong kinetic energy generated by the high tangential speed and high-frequency mechanical effects of the high-speed rotation of the rotor, the material is subjected to strong hydraulic shear, centrifugal compression, liquid layer friction, impact tearing, and turbulence in the narrow gap between the stator and rotor, resulting in the immiscible solid, liquid, and gas phases being uniformly and finely dispersed and emulsified in an instant under the combined action of corresponding mature processes and appropriate additives, After high-frequency cycling, stable and high-quality products are ultimately obtained.
