The determination of fineness is to check the size or uniformity of dispersion of particles such as color method or paint paste inner pigment (filler), expressed in µm. It is the quality inspection index of paint factory products. The fineness of the coating
The particle size of the pigment (filler), the higher the degree of dispersion in the paint, the finer its fineness, and the smoother the paint film. However, due to different types of coatings and different uses, the requirements for the fineness of the material removal are different. Generally, in the coating system composed of primer, middle coat and top coat, the top coat is the thinnest, the middle coat is the second deepest, and the primer is the thinnest.
At present, the scraper Fineness Meter is commonly used to measure the composition of paint. There are GB/T1724 standard Fineness Meter and IS0 1524 standard Fineness Meter. In container manufacturing plants, the fineness index of paint is generally not determined.
