High shear emulsifying machine is a kind of material can be fully refined and uniform machine, its name source should be able to promote oily material (oil phase) and water-based material (water phase) mixing and forming a uniform emulsion machine. And refined uniform machine and there are a variety of, such as ball mill, sand (bead) mill, grinder, colloid mill, dispersing machine, high pressure homogenizing machine, these can refine the scope of application of the material machine, refining homogenizing ability is not the same. And the high shear emulsifier has the function of refining, dispersing and homogenizing. It is mainly used for liquid-liquid emulsification and homogenization, liquid-solid (powder, small particles) refinement and dispersion.
High shear emulsifier overview
From the rotor structure is divided into slotted ring type, closed groove ring type, four straight blade rotor, three curved blade rotor, multi-layer open (closed) groove ring type;
From the stator structure is divided into straight groove open type, straight groove closed, chute open type, chute closed, mesh, round hole, multi-layer various;
From the work sealing requirements are divided into open (suspension, kettle installed) type, with sealing emulsifying machine (machine seal, water seal, oil seal, magnetic transmission seal);
Closed stator adopts precision fit, slotted stator general fit gap is slightly larger.
The rotor and stator of the working head of emulsifier are usually made of forging, so they have good comprehensive mechanical properties. And has high shear, dispersion, homogenization, emulsification efficiency. Shear head is composed of rotor and stator, in which the rotor with its high linear speed and high frequency mechanical effect to the strong kinetic energy, so that the material in the rotor, stator precision clearance by shear, centrifugal extrusion, liquid layer friction, impact tearing and turbulence, so as to achieve the effect of dispersion, grinding, emulsification.
The working principle of A high shear emulsifier
is an efficient, rapid and uniform distribution of one or more phases into another continuous phase, which is normally insoluble. Due to their high rotor generated by high speed rotating tangential velocity and high frequency mechanical effect, the strong momentum of the material in the narrow gap, rotor by strong mechanical and hydraulic shear, centrifugal extrusion, liquid such as friction, impact and tear turbulent layer combination, so that the miscibility of the solid phase, liquid phase and gas phase in the corresponding mature technology and a moderate amount of additives, The emulsion is dispersed evenly and finely in an instant, and the stable and high-quality products are finally obtained through high frequency cycle.
The performance characteristics of.
Main performance characteristics of high shear emulsifier
1. Also known as centrifugal homogenizer, especially suitable for the pre-treatment section of materials;
