Ultrasonic comminution principle of liquid crystal ultrasonic cell grinder

Liquid crystal ultrasonic cell crusher is a kind of multifunctional and multi-purpose instrument which uses strong ultrasound to produce cavitation effect in liquid and ultrasonic treatment of substances It can be used for breaking many kinds of animal and plant cells, bacteria, spores, emulsifying, separating, dispersing, homogenizing, extracting, degassing, cleaning and accelerating chemical reaction Liquid crystal ultrasonic cell grinder is widely used in biochemistry, microbiology, pharmaceutical chemistry, surface chemistry, physics, zoology and other fields The crusher is suitable for the industrialization requirements of biological, pharmaceutical, nano material preparation and other projects It is used for batch crushing of various kinds of animal and plant cells, dispersion, homogenization, emulsification of certain specific pharmaceutical materials Principle of ultrasonic comminution of liquid crystal ultrasonic cell crusher: under the action of ultrasonic, the solid particles or biological tissues in the liquid are broken This process is called ultrasonic comminution Ultrasonic comminution is mainly realized by the combination of ultrasonic cavitation effect and mechanical action The main performance is that when ultrasonic propagates in liquid medium, there are dense vegetable areas, and negative pressure can produce many cavities in the medium These cavities expand and explode with the change of high frequency pressure of vibration When the vacuum cavity explodes, the instantaneous pressure can reach thousands or even tens of thousands of atmospheric pressure Such a large impact force can bring the surrounding material particles into the local explosion of the vacuum cavity Shatter On the other hand, due to the violent vibration caused by the ultrasonic wave in the liquid, the substances move at a high speed, so that they collide with each other or with the wall of the instrument and break up.
