Particle fineness of powder coatings

Update:18 Feb,2020

Then the significant difference between powder coatings and solvent-based coatings is that the dispersion medium is different, and if it can be used in solvent-based coatings, then it is used in the presence of powder solvents as a dispersion medium, and it can be used in powder coatings. Medium, then it is to use purified compressed air as a dispersion medium, and it is to be in a dispersed state when the powder coating is sprayed, then it is to not be able to adjust the particle size of the coating, it is to compare to suit static electricity The particle size of the sprayed powder is important, and it can be used in powder coatings suitable for electrostatic spraying, then it is good for particle sizes between 10 microns and 90 microns, and it can be used for powders with particle sizes less than 10 microns. It is called ultra-fine powder, so it comes in that it is easily lost in the atmosphere, and it is because the content of ultra-fine powder cannot be too much, so it is here. It is worth noting that it can come in the powder particles The degree is related to the thickness of the coating film, so it is to have a certain distribution range for the particle size of the powder coating. So that is possible to obtain a uniform thickness in the coating film
