Problems solved by technology

[0003] At present, the detection method of particles in the solution in the scientific research and production process usually adopts the off-line sampling method, which cannot detect the particle size in the production process in a timely and dynamic manner, which has a certain impact on the actual scientific research and production benefits

At present, the commonly used detection methods mainly include ultrasonic method, photoelectric method, conductivity method, high-speed camera method, laser method, resistance method and other detection methods. The existing detection technology methods can only give the overall content of solid particles in the solution. Technical methods can give the statistical quantity of particles, but cannot give the size of individual particles
