The fineness of PA11 powder used for wire basket coating is usually selected according to the specific coating process:
Micro-coating process: If the micro-coating process is adopted, the powder diameter is generally about 55μm, which is more suitable. Such fineness can control the coating thickness at 100-150μm, and can form a relatively uniform and moderately thick coating on the surface of the wire basket, providing good protection and appearance.
Electrostatic spraying: For electrostatic spraying process, a powder diameter of 30-50μm is a better choice. Powders of this fineness can be better adsorbed on the surface of the wire basket under the action of static electricity, and can make the coating thickness reach 80-200μm, which not only ensures the adhesion of the coating, but also can adjust the coating thickness as needed to meet different usage requirements.
In addition, the choice of powder fineness may also be affected by factors such as the use environment of the wire basket and the specific requirements for coating performance. For example, if the wire basket needs to be used in a highly corrosive environment, a thicker coating may be required. At this time, if the process permits, a slightly coarser or finer powder can be selected to adjust the coating thickness and density; if the surface smoothness of the coating is very high, a finer powder may be required to obtain a finer surface.
