Maintenance and upkeep of high shear emulsifier
The high shear emulsification technology has functions such as mixing, crushing, dispersion, and emulsification, which have a particularly significant crushing effect on polymer materials. It can effectively solve the crushing and emulsification problems of various materials, replacing traditional colloid grinding equipment. Compared with traditional production processes, it has four major advantages: low energy consumption, low production costs, high product quality, and ultra refinement. Suitable for working under normal pressure, vacuum, and positive pressure conditions. It has stable operation, low noise, convenient cleaning, flexible mobility, and can be continuously used for ultrafine dispersion and emulsification of materials.
Maintenance work of high shear emulsifier:
1. During installation or use, emulsifying equipment should be handled with care to avoid violent vibrations.
2. Maintenance personnel should regularly check the fastening connection bolts, especially bolts and nuts that are prone to loosening, as well as whether each foot plate is loose.
3. During the maintenance and replacement of the rotor, it is recommended to use specialized tools and avoid forceful strikes that may cause deformation and damage to the components.
4. The shaft sleeve of the high shear emulsifier is a vulnerable part, and its material can vary according to the nature of the user's material. However, the wear of the shaft sleeve needs to be regularly checked by maintenance personnel to ensure that the rotor and stator do not collide.
The characteristics of high shear dispersion emulsifier
The high shear dispersion emulsifier has a wide range of applications, with six major characteristics: high-speed mixing, dispersion, rapid refinement, dissolution, homogenization, and emulsification. The high shear dispersing emulsifier is suitable for processes with high linear speed, which can enhance the processing of materials, making dispersion, homogenization, emulsification, and mixing faster and more effective.
Working principle of high shear dispersion emulsifier
The high shear dispersing emulsifier has six major characteristics: high-speed mixing, dispersion, rapid refinement, dissolution, homogenization, and emulsification. The mechanical and hydraulic high-speed shear force is the key to the operation of the high shear dispersion emulsifier. The high-speed rotating rotor and stator are precisely matched, resulting in high shear tangent speed and the mechanical and hydraulic shear force caused by high-frequency mechanical effects, ensuring that the material can withstand hundreds of thousands of shearing times per minute. The material is subjected to strong centrifugal compression, shearing, spraying, liquid layer friction, collision in the precise gap between the fixed and rotor of the high shear dispersion emulsifier Under the combined action of tearing refinement and complex liquid flows such as turbulence, turbulence, and eddy currents, the immiscible liquid phase, liquid gas phase, and liquid solid phase are instantly uniformly refined, mixed, dispersed, homogenized, and emulsified under corresponding mature process conditions. In this way, they cycle back and forth, ultimately obtaining high-quality products.
The shearing process of the high shear dispersing emulsifier:
Under the centrifugal force generated by the high-speed rotating rotor, the material in the figure is simultaneously sucked into the working chamber axially from the upper and lower feeding areas of the working head.
2. The strong centrifugal force throws the material radially into the narrow and precise gap between the stator and rotor. Simultaneously subjected to centrifugal compression, impact and other forces, the material is initially dispersed and emulsified.
3. Generate a linear velocity of at least 15m/s at the outer end of the high-speed rotating rotor, up to 40m/s, and form strong mechanical and hydraulic shear, liquid layer friction, impact tearing to fully disperse, emulsify, homogenize, crush, and shoot out through the stator slot.
4. The material is continuously ejected from the radial direction at high speed, changing its flow direction under the resistance of the material itself and the container wall. At the same time, under the action of the upper and lower axial suction forces generated in the rotor area, strong turbulent turbulence is formed in the upper and lower directions. The material undergoes several cycles and ultimately completes the processes of dispersion, emulsification, and homogenization.
