dispersion composition, flowability, hygroscopicity, saturation density, and pseudo-dilution ability.<\/p>\n
Large particle size is observed after particle size powder paints. Permissible size is from 5 to 350 mkm. Depending on the method of application of the paint, the permissible particle size varies.<\/p>\n
Requirements for all powder coating paints – good flowability. If there is insufficient fluidity, it is difficult to overcoat the paint. Criterion for assessing fluidity – the rate of internal friction angle of the powder. At normal flow, the natural angle curvature is usually between 36 and 45 degrees<\/p>\n
Powder coating has moisture absorption properties. As a result, the flowability of the powder is reduced. The electrical parameters of the paint may change and this may be reflected in the film formation.<\/p>\n
It is one of the most characteristic and the most characteristic properties of powder color. The density density of the industrial powder paint is from 200 to 800 kg \/ m2.Sis indicator depends on the color composition, shape and degree of polydisperse particle size.<\/p>\n
– the formation of a boiling particle layer, which is required by the technology to form the coating depends on the structure and properties of the powder. Pseudo-liquefaction is not able to form strong, wet, dispersible powder with a natural angle of 43 degrees. It is especially good for powders that consist of larger particles that are more ball-shaped.
