SINA launches ultra-high speed three-stage high shear disperser
Date: 2019-09-04Read: 2

Product Introduction:

High rotational speed and shear rate are important for obtaining ultrafine suspensions. According to some industry specific requirements, Sina Corporation has developed the CRS200 based on the CR2000 series0Ultra high speed three-stage high shear disperserIts shear rate can exceed 100.00 rpm, and the rotor speed can reach 40m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower. Due to its high energy density, it can achieve the particle size of a regular high-pressure homogenizer at a pressure of 400BAR without the need for other auxiliary dispersing equipment

Working Principle:

Ultra high speed three-stage high shear disperserIt is a device used to quickly and uniformly transfer one or more phases (liquid, solid) into another immiscible continuous phase (usually liquid). When the fineness of one or more materials reaches the micrometer or even nanometer level, the system can be considered homogeneous. When external energy is input, the two materials recombine into a homogeneous phase. The high shear homogenizer, due to the strong kinetic energy brought by the high tangent speed and high-frequency mechanical effect generated by the high-speed rotation of the rotor, makes the materials subject to intense mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tear and turbulence in the narrow gap between the stator and rotor, forming suspension (solid/liquid), lotion (liquid/liquid) and foam (gas/liquid). The high shear homogenizer instantly disperses and emulsifies immiscible solid, liquid, and gas phases uniformly and finely under the combined action of corresponding processes and appropriate additives. Through the cyclic operation of the high-frequency pipeline high shear dispersion homogenizer, stable high-quality products are finally obtained.

Calculation of linear velocity

The definition of shear rate is the relative velocity of the liquid layer between two surfaces.

- Shear rate (s-1)=v rate (m/s)
G distance between stator and rotor (m)

As can be seen from the above, the shear rate depends on the following factors:

- Linear velocity of the rotor

In this case, the distance between the two surfaces is the rotor stator spacing.
The spacing range between Sina stator and rotor is 0.2~0.4 mm

The upper limit processing capacity in Table 1 refers to the measurement data of the medium being "water".

The processing capacity depends on the viscosity, consistency, and requirements of the final product of the material.

The flow rates of various models within the 3 parameters mainly depend on the precision of the configured emulsifying head.

The data in this table may vary due to technical changes and customization. The correct parameters are based on the actual product provided
