How does a laser particle size analyzer detect the particle size distribution of toner?

Toner is a fine, particulate substance made from carbon or carbonaceous materials. It has high blackness and coverage performance, and is widely used in printing, copying, photography and other fields. Carbon powder is usually composed of carbon black, resin, additives, etc., and can be prepared by grinding, mixing and processing. It has good adhesion, color stability and durability and is suitable for a variety of substrates such as paper, plastic, metal, etc. The particle size and distribution of toner directly affect the performance of toner, which is related to the manufacturer's process equipment. Small particles can increase the resolution of the copy, are easily charged in the developing unit, and make the copy high-density, while large particles improve the fluidity of the toner, thus ensuring good transportation in the developing unit. However, They carry only a relatively small amount of charge, so they tend to remain and accumulate in the developing unit. This time, Winner3003 was used to detect the particle size distribution and size of toner. Manufacturers can further improve production supervision and improve product quality through particle size measurement.
