In order to obtain the correct data of the primary particle size, it is often necessary to open the agglomerated particles in the particle size test to form a particle monomer and keep it uniformly dispersed in the medium. This operation is called "dispersion". The requirement of the laser particle size analyzer for the dispersion system is "dispersion without segregation". Dispersion techniques a...

Fisher's method is a relatively simple particle size measurement method, which is based on measuring the speed of air passing through the powder accumulation, and then obtaining the average particle size of the powder according to the Kozeny-Carman formula. However, the Fisher method is a relative measurement method, which cannot accurately determine the true particle size of the powder, and is on...

1. Mechanical properties Due to the fact that nanomaterials are composed of nanoparticles, and when the particles are at the nanoscale, the strength, hardness, and other mechanical properties of the material will increase as the particle size decreases. It is precisely because of this property of nanomaterials that they can be used for certain packaging that requires strength and hardness, solving...

(1) Particle size characterization Particles disperse in liquid to form a suspension system. The smaller the particle size and the more stable it becomes over time, the better its dispersion and less likely it is to agglomerate. Particle size characterization is commonly used to characterize the particle dispersion before and after surface modification. The better the dispersion of particles, the ...
