Information

The manufacturer of Twin Screw Extruders for Powder Coatings tells you that at present, in powder equipment, if the thickness of the coating film is thicker, the surface tends to be flatter. The main factors affecting the smoothness of the powder coating film of powder equipment are the particle size and its distribution, melt viscosity, and the dispersion state of pigments and curing agents.

Factors affecting the efficiency of powder equipment:
1. Distribution of coating film thickness: The manufacturer of Twin Screw Extruders for Powder Coatings tells you that in powder equipment coating, due to the unevenness of the sprayed powder, the unevenness of the coating film thickness is about twice that of solvent coating. Correctly grasp the effective spray pattern of the coating equipment, control the indirect time of spraying, and prevent the unevenness of spraying.
2. Coating efficiency: The main factors affecting the coating efficiency of powder mechanical powder coatings are the charging method of the coating equipment, the particle size distribution of the powder, and the temperature and humidity of the coating environment. For this purpose, suitable powder coatings are in the range of 10-80 μm.
The manufacturer of Twin Screw Extruders for Powder Coatings tells you that because the fine particles in the powder coating are easy to accumulate in the spray gun head or the part where the airflow direction changes in the pipeline after the coating equipment, when the accumulation reaches a certain level, it will be sprayed out in a coagulated state and adhered to the surface. Above the object to be coated, in the construction of electrostatic spraying, the problem of environmental dust should also be paid enough attention. Twin Screw Extruders for Powder Coatings manufacturers tell you that dust comes from the air, fibers on the operator's powder equipment and flaking on the baking equipment, etc. These dusts can also cause contamination of the coating film and carry particles during the electrostatic powder coating process.
