Introduction:
The effect of ultrasound on solid particle suspensions in liquids or emulsions, that is, the suspension of two liquid substances without mixing them, deserves our attention. The action of ultrasonic dispersion system in these suspensions will produce high-intensity micro jet, but there is no cavitation phenomenon, which will produce interesting results. We will detect a suspension composed of solid particles of different sizes, which will be divided into several parts, and particles of the same size will be evenly distributed in the liquid. And compared with the particles without ultrasonic treatment, these particles will remain suspended for a longer time.
Principle:
Ultrasonic dispersion system will change the liquid into a dispersed state, that is, fine or ultra-fine ultrasonic grinding of solid or fluid due to ultrasonic vibration effect. Grinding solid particles suspended in the liquid or simply destroying metal or stone type solids and viscous substances immersed in the liquid requires a way, because destroying strong substances requires shock waves due to the rupture of cavitation bubbles. Due to the particularity of ultrasonic field generated in liquid medium, ultrasonic dispersion provides a highly dispersed, uniform and chemically pure suspension (particle size less than 1) μ m)
Advantages:
Compared with some traditional dispersion methods, ultrasonic dispersion is an effective dispersion method, which has lower cost and is easy to operate and maintain.
Application:
Ultrasonic dispersion equipment ultrasonic polymer dispersion equipment can be used for dispersion and homogenization of graphene, ink and coating; It is also widely used in petroleum emulsification, extraction and processing of traditional Chinese medicine, crushing of cells and ballast water, disinfection treatment, accelerated reaction of chemical raw materials and so on.
