The use of high shear dispersing emulsifier
Date: 2024-08-20Read: 8
The development of high shear dispersing emulsifier technology has formed a new discipline that is different from traditional mixing, and is constantly expanding its application fields and technological updates. It is praised by users as the "industrial revolution of mixers".
The main structure of the current high shear dispersing emulsifier is the stator and rotor system, and its structural form has also undergone updates, from blade structure to the current claw structure, from single piece shearing to multi-layer dual bite shearing, from single piece suction to bidirectional suction, efficiently, quickly, and uniformly distributing one or more phases into another continuous phase; Under normal circumstances, the various phases are immiscible with each other. Due to the high tangential velocity generated by the high-speed rotation of the rotor and the strong kinetic energy brought by high-frequency mechanical effects, the material is subjected to strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact tearing, and turbulence in the narrow gap between the stator and rotor. As a result, the immiscible solid, liquid, and gas phases are instantly uniformly and finely dispersed and emulsified under the joint action of corresponding mature processes and appropriate additives. After high-frequency cycling, relatively stable and high-quality products are finally obtained.
The high shear dispersing emulsifier is mainly used in any process that requires stirring, homogenization, crushing, suspension, and dissolution, such as cosmetic emulsions and emulsions. as shown below
Mixing: syrup, shampoo, detergent, fruit juice concentrate, yogurt, dessert, mixed dairy products, ink, porcelain glaze.
Dispersion mixing: dissolution of methyl cellulose, dissolution of colloids, dissolution of carbides, oil-water emulsification, pre mixing, seasoning production, stabilizer dissolution, smoke, salt, alumina, pesticides.
Dispersion: suspension, pill coating, drug depolymerization, paint dispersion, lipstick, vegetable soup, mustard mixture, catalyst, matting agent, metal, pigment, modified asphalt, preparation and depolymerization of nano materials.
Emulsification: lotion, ointment, cream, facial mask, face cream, emulsified essence, oil-water emulsification, emulsified asphalt, resin emulsification, wax emulsification, water-based polyurethane emulsification, pesticide.
Homogenization: medical lotion, ointment, cream, facial mask, face cream, tissue homogenate, dairy homogenization, juice, printing ink, jam
