Emulsion pot plays an important role in industrial equipment

Emulsification pot plays an important role in the mixing system of industrial equipment, especially in solid-liquid mixing, liquid-liquid mixing, oil-water emulsification, dispersion and homogenization, shear grinding. The reason why it is called an emulsifying pot is that it should be able to achieve emulsification. Now the application of the emulsifying pot is not limited to "emulsification", because of its unique shearing effect, the crushing impact of the powder particles in the liquid is finally refined to the ideal particle size, so that the solid is fully mixed into the liquid and forms a relatively stable suspension, this process is "dispersion". Of course, as with emulsifiers, the stability of the suspension is increased by the addition of dispersants.

NowEmulsifying potApplications are not limited"Emulsification", due to its unique shearing effect, the crushing impact of the powder particles in the liquid is finally refined to the ideal particle size, so that the solid is fully mixed into the liquid and forms a relatively stable suspension. This process is also "dispersion". Of course, as with emulsifiers, the stability of the suspension can be enhanced by the addition of dispersants. When a solid substance can be completely dissolved by liquid through contact with liquid for a certain period of time, the small particles formed by shear impact will be dissolved by liquid more quickly because its specific surface area increases many times.
When people get used to getting fine particles by high-pressure homogenizer,"Refinement" is equated with "homogenization", thusEmulsifying potThe effect of material refinement and full mixing isThe process of "homogenization. So, we can also putEmulsifying potKnown as a homogenizer, for ease of distinction, it can generally be used as a high-speed or high-shear homogenizer, so that it is right.Emulsifying potThere are many ways to call it:high shearEmulsifying potHigh shear homogenizer, high shear dispersionEmulsifying potHigh shear homogenizationEmulsifying potHigh shear homogeneous dispersionEmulsifying potWait.
Emulsifying potThe strength of the shearing action directly affects the final fineness. After analysis, it is mainly related to the sharpness of the blade, hardness, rotation stator gap, relative movement speed of the two cutting edges and the particle size allowed to pass. Normally, the sharpness of the blade, hardness, rotation stator gap and the particle size allowed to pass are basically fixed or do not want to change, so the relative movement speed of the blade is the most influential factor, this is expressed by the circumferential linear speed of the rotor, which is high, the density of the cutting or impact on the radially flowing fluid is high, and thus the refining effect is strong, and vice versa. However, the line speed is not the greater the better, when reaching a very high value, there is a tendency to form a blocking flow, so the flow becomes very small, and the heat is very high, some materials in turn will gather, so that the result is not ideal.
So usually we say whether the stirring speed is the shear speed? Studied Senior high school physics know, speed is divided into angular velocity and linear velocity, shear speed of course refers to the linear velocity, linear velocity= angular velocity × diameter × π, so why is it used for industrial productionEmulsifying potThe speed is generally only3000rpm or 1500rpm, while the laboratoryEmulsifying potSpeed hasThe height of 10000rpm or 280000rpm is to consider the diameter factor, so that the shearing linear speed of the two is close, and the final effect is close.
