How is the particle size distribution of colored pigments measured?

Pigment is a colored fine-grained powdery substance that is generally insoluble in water and can be dispersed in various media such as oils, solvents, and resins. It has hiding power, tinting power, and is relatively stable to light. It is often used in the preparation of coatings, inks, and colored plastics and rubber, so it can also be called a colorant. The particle size of the pigment not only affects the coloring strength, transparency, shading, weather fastness, and solvent resistance, but also has a certain impact on the gloss of the colored coating film. Of course, it is also related to the film-forming gloss of the application medium. degree has an important relationship. When the pigment particles are spherical and the particle size is in the range of 0.01 to 1 μm, a smoother surface coating will be formed, which is related to the shape of the pigment particles, especially the length/width ratio of needle-shaped or rod-shaped particles. important role. Use winner2000E to control the particle size of pigments. Through product testing and analysis, we provide technical basis for quality inspection and optimization, and achieve very good results.
