Information

Grinding classifying systems for powder coating manufacturers tell you that powder coating formulations are generally composed of film formers, pigments, fillers and additives. In actual production, it is found that the type of film formers and filler content affect the particle size and distribution of the produced powder. Larger, the type of film-forming material and the content of filler can directly affect the toughness of the melt-extruded tablet at room temperature. When grinding the screening system, the more "difficult to grind" the tablet, the smaller the amount of fine powder (<10μm) in the obtained powder with an average particle size close to:

1. Film-forming materials Currently, the more common film-forming materials are pure polyester type, epoxy polyester type, and pure epoxy type. The sheets after melt extrusion have different flexibility (plasticity) at room temperature. The manufacturer of grinding classifying systems for powder coating tells you that the pure epoxy type is generally more brittle, followed by the epoxy polyester type, and the pure polyester type is the most flexible, and it is also different types of polyester in the pure polyester system cured by TGIC. Esters also vary in flexibility.
2. Filler content The amount of filler also directly affects the brittleness of the tablet. The greater the filler content, the more brittle the tablet, the easier it is to break, and the less likely it is to obtain a powder with a concentrated particle size distribution. As the amount of filler increases, the tablets are more easily broken, and the particle size distribution obtained is less concentrated, and the fine powder content in it also increases significantly with the increase of filler. The manufacturer of grinding classifying systems for powder coating tells you that the analysis is that the addition of fillers reduces the flexibility of the tablet, and the tablet is particularly easy to shatter when stressed.
3. Sheet temperature The sheet temperature also directly affects the grinding efficiency and particle size distribution. Generally, the actual temperature of the sheet is required to be below 30°C during production, which is beneficial to the grinding efficiency and also affects the particle size distribution and the shape of the powder particles. There are benefits to being spherical. Grinding when the temperature is too high will cause "jagged edges", etc., and it is easy to cause current overload.
The manufacturer of grinding classifying systems for powder coating tells you that in terms of formulation, you can choose polyesters with different flexibility and adjust the amount of filler added to achieve a balance between particle size distribution, performance and cost.
