Reciprocating spraying equipment is also called painting equipment, which is a special tool for spraying and processing the surface to cover the protective layer or the decoration layer. At present, industrial technology is undergoing continuous development. Pure craftsmanship can no longer meet the needs of the market. Spraying has developed from craftsmanship to industrial automation, and the degree of automation is getting higher and higher, so spraying production lines are becoming more and more widely used. , And deepen into multiple areas of the national economy.
It has become a trend to use spray equipment for spray processing. Today, we understand what problems the sprayer should pay attention to during the spraying process?
During spray processing, the appearance of the sprayer should be perpendicular to the surface of the coating. When setting the program to operate the spray gun, the width between the spray gun and the spray gun should not be too large. Otherwise, uneven coating of processed products may be formed. The direction of the spray gun is always parallel to the coating surface of the product to ensure the uniformity of the coating. The spray gun works at a stable speed, and the running speed is adjusted well to prevent uneven coating thickness, running speed too fast, coating too thin or too thick.
The coating is too thin; the main performance is that the coating cannot reach the required thickness after conventional spraying.
The coating is too thick, mainly due to the sagging phenomenon, the dry appearance of the coating and the deeper layer and the phenomenon of the coating shell.
The spray processing operations are mainly the operation and use of spray equipment. Improper operation of spraying equipment can cause defects in product coatings. Coating defects are mainly reflected in three aspects: uneven coating, inconsistent coating color, poor coating smoothness, etc.
The distance between the spray gun and the coating surface is called the gun distance. The gun distance is too small, the eruption pressure is too large, and the reaction force is large. The coating simply appears uneven and the coating width is too small and the coating is too thick. If the gun distance is too large, the spraying pressure will lose too much, the coating will simply drop, and the spraying size will be too large, resulting in the partial spraying volume of the coating being too small, and the coating cannot meet the thickness requirements.
Through the above study, I hope we have some understanding of spraying. In the later stage, if you want to know more about spraying equipment, please pay attention to us.
