Emulsifier is also known as high shear mixer, homogeneous emulsifier, high shear mixing tank, etc. Emulsifier is also divided into: intermittent emulsifier, pipeline emulsifier (emulsification pump), is through the high-speed rotation of the emulsification head connected to the motor, the material is sheared, dispersed, impact. This way the material becomes more delicate, prompting oil-water, gas-liquid, solid-liquid, fusion. Widely used in cosmetics, pharmaceuticals, food, ink fine chemicals, petrochemicals and other products to be used in the emulsifier.

High-shear emulsifier is through the rotor high-speed smooth rotation, the formation of high-frequency, strong circumferential tangential speed, angular velocity and other comprehensive kinetic energy efficiency, in the role of the stator, the stator, rotor reasonable narrow gap in the formation of strong, reciprocal hydraulic shear, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects, so that the material in the container cycle of the above work process, so as to obtain the required products.

Intermittent high-shear emulsifier working process.

1, in the high-speed rotor generated by the centrifugal force, the material from the work head of the upper and lower feed (two-way suction) area at the same time from the axial suction work cavity or from the bottom of the work head suction material (one-way suction).

2、The strong centrifugal force will throw the material from the radial direction into the narrow and precise gap between the stator and rotor. At the same time by the centrifugal extrusion, impact and other forces, so that the material initially dispersed emulsification.

3, in the high-speed rotation of the outer end of the rotor to produce at least 15m / s above the linear speed, high can be up to 40m / s, and the formation of strong mechanical and hydraulic shear, liquid layer friction, impact tear, so that the material fully dispersed, emulsified, homogeneous, broken, while shooting through the stator slot hole.

4、Materials are continuously shot out from the radial direction at high speed, and change the flow direction under the resistance of the material itself and the wall of the container, and at the same time, under the action of the upper and lower axial suction force generated in the rotor area, and form the upper and lower two strong turning turbulent flow. The material goes through several cycles, thus completing the process of dispersion, emulsification and homogenization.

The emulsifier has a wide range of applications, such as adhesives, paints and coatings, cosmetics, food, pharmaceuticals, plastic resins, printing and dyeing, ink, asphalt and other industries.

Fine chemicals: plastics, fillers, adhesives, resins, silicone oil, sealants, pastes, surfactants, carbon black, defoamers, brighteners, leather auxiliaries, coagulants, etc.

Petrochemicals: heavy oil emulsification, diesel emulsification, lubricating oil, etc.

Daily-use chemicals: laundry powder, concentrated laundry powder, liquid detergent, all kinds of cosmetics, skin care products, etc.

Coating and ink: emulsion paint, interior and exterior wall paint, water-based oil-based paint, nano paint, coating additives, printing ink, printing ink, textile dyes, pigments, etc.

Biological medicine: sugar coating, injection, antibacterial agent, protein dispersant, pharmaceutical cream, health care products, etc.

Pesticide and fertilizer: insecticide, herbicide, drug emulsion, pesticide auxiliaries, fertilizer, etc.

Food industry: chocolate shell, fruit pulp, mustard, crumb cake, salad dressing, soft drink, mango juice, tomato pulp, sugar solution, edible flavor, additive, etc.

Nano materials: nano calcium carbonate, nano coatings, all kinds of nano materials additives, etc.
