Electric ultrasonic particle size analysis point ultrasound analysis is the latest in particle size analysis method, the particle size measurement range is 5 ?? m ~ 100 ?? m. It analyzes the principle is more complicated, simply put, when sound waves inside the sample droplets conduction angle, the instrument can analyze the sound wave attenuation in a wide range of ultrasonic frequencies, through the measured acoustic attenuation spectra can be calculated attenuation value and book Relationship between particle size. Analysis required density of the particles and the liquid, the viscosity of the liquid, the mass fraction of the particles and other parameters of the emulsion or colloid particles in a flexible, but also the thermal expansion parameters of particles (including the particle size, ξ electric potential, etc.), no dilution, Avoid the laser particle size analysis method can not analyze the dispersion of high concentration of defect size and high precision, a wider range of particle size analysis. Electrophoresis (electrophoresis) in the electric field force, directed migration of charged particles in the suspension system, the size of the particle mobility and particle size related to its mobility by measuring the particle size can be calculated. Electrophoresis can measure less than 1 ?? m of particle size droplets angle manufacturers, but only an average particle size of the water droplets Shenzhen angle, it is difficult to measure the particle size distribution. Fisher method (fisher? Method) Fisher method first law of the land belonging to the steady flow of gas (laminar) state. Under constant pressure, the air first through the measured particle? Accumulation body, and then flows through an adjustable needle valve atmosphere. According to the air flow resistance and stole particles generated during accumulation body surface area can be obtained and the average size of the particles. Fisher method is a method of measuring the relative angle of water droplets in Guangzhou, size book called the Fibonacci average particle size, can not accurately reflect the true size of the particles, nor other particle sizing methods and the results were compared, not accurately reflect the particles The true particle size, and the results can not be obtained by other method of particle size measurement is compared, only used to control the process and product quality. Typical products are the United States Fisher Number sieve grade powder tester.
