Powder coatings (including nano-materials) dispersed mainly by the action of shear forces. Nanomaterials dispersion coating system generally adopts a decentralized approach to achieve dispersion.

High shear dispersing machine: the core components of high shear dispersing machine stator / rotor structure, high tangential speed and high frequency mechanical effect high speed rotation of the rotor are generated from the strong momentum, so that the material in the stator and rotor narrow gap subject to strong mechanical shear, hydraulic shear, centrifugal extrusion, liquid layer friction, impact and tear combined effects of turbulence, so that immiscible solid, liquid and gas in the corresponding process conditions are ripe, the moment uniformly finely dispersed through high-frequency circulation, stable high-quality final product. Compared with the three-roll mill, a ball mill, a sand mill, high-shear dispersing machines high efficiency, low energy consumption significant advantages, is the preferred dispersion process.

High shear dispersing machine works

◆ under the centrifugal force generated by high speed rotation of the rotor, the material from the working head of the upper and lower feed zone, while the suction working chamber from the axial direction.
◆ strong centrifugal force the material thrown from the radial meditation, precision narrow gap between the rotor while being centrifugal extrusion, hydraulic friction, impact and other integrated hydraulic force, the initial material is dispersed.
◆ High-speed rotation of the rotor to generate at least 15m / s or more linear velocity, the material is sufficiently dispersed crushed under intense hydraulic shear, the liquid layer friction, tearing collision effects, through the stator slot high speed.
◆ material continuously emitted from the radial speed, change the flow in the material itself and the container wall of resistance, at the same time under the action of the rotor region generated lower axial suction force, and the formation of upper and lower stocks strong flip turbulence. After several cycles of materials, the final completion of the dispersion process.

High shear dispersing machine with conventional mixing equipment has the following advantages:

◆ large capacity, suitable for industrial continuous production
◆ narrow particle size distribution, uniform high
◆ saving, high efficiency, energy saving
◆ low noise, smooth operation
◆ no dead ends, material 100% cut by dispersing
◆ novel design, simple operation, easy maintenance
◆ can achieve automatic control
