Factors affecting the spraying effect of powder coatings

Influence of spraying workers' proficiency on powder coating spraying effect

The proficiency of operators is also an important factor affecting the appearance quality and spraying area of powder coating.

The thickness of coating should not be controlled under the condition of 80-90 μ M. During spraying operation, the spray gun should always be vertical to the workpiece. The spray gun should be translated from left to right with uniform speed, and the distance between the upper and lower parts should be moderate. Do not spray powder coating too much and there should be no leakage of spraying.

Workers do not align the spraying parts one to two seconds after the spray gun is turned on, and then start spraying after the powder coating is evenly distributed (because there are a few spray guns that spit powder when they just shoot).

When spraying iron wire, thin strip and tubular workpieces, workers should adjust the spray gun so that the powder coating output of the spray gun is smaller and the gun moving speed is slower. Generally, the translation speed is 80-120mm / s. However, these measures can be used to increase the powder rate of the spray gun and ensure the high powder recovery rate
