Particle size refers to the size of a particle, and mesh count refers to fineness. For regular spherical particles, we can precisely describe their size by "diameter". In actual production, due to the instability of control, in the vast majority of cases, the shape of the particles is not spherical and cannot be expressed by diameter. Therefore, when representing the size of particles, the concept of "particle size" was introduced. The so-called particle size can be understood as a one-dimensional dimension. For the same particle, due to different application scenarios, the measurement methods often vary, and thus the obtained particle size values are also different. What is seen under the microscope is the projected size of the particles on the plane perpendicular to the line of sight. The particle size obtained by the sieving method is the size of the sieve holes. The diameter of spherical particles with the same sedimentation characteristics is obtained by the sedimentation measurement method. In production practice, what is often involved is not a single particle size, but a collection of several particles with different particle sizes, that is, a particle group. How to describe the particle size characteristics of all particles in a particle group has also become a difficult problem. Nowadays, the average particle size of the particle group is generally calculated by statistical mathematics methods, and then the size and distribution of the particles are described in segments, that is, the particle size distribution, that is, the particle content in different particle size intervals of the pigment powder. The particle size distribution of applications of jotio titanium dioxide is a comprehensive indicator, which seriously affects the performance of applications of jotio titanium dioxide and the application performance of products. Therefore, The discussion on covering power and dispersibility can be analyzed directly from the particle size distribution. The factors influencing the particle size distribution of titanium dioxide are rather complex. Firstly, it is the size of the original particle size after hydrolysis. By controlling and adjusting the hydrolysis process conditions, the original particle size can be kept within a certain range. Secondly, there is the calcination temperature. During the calcination process of Titanic acid, the particles go through a crystal form transformation period and a growth period. By controlling an appropriate temperature, the growth of particles can be kept within a certain range. The last step is the crushing of the product. Usually, the Raymond mill is modified and the speed of the analyzer is adjusted to control the crushing quality. At the same time, other crushing equipment can be adopted. The particle size and distribution of titanium dioxide are one of the very important influencing factors. The particle size of titanium white powder has a significant impact on its scattering coefficient. When its particle size is 200W, the scattering coefficient is the highest. At this time, the tinting power and covering power of titanium dioxide are the best, and the whiteness and gloss are the best.
