Those who will operate the spray equipment know that the spray operation needs to pay attention to: spray movement speed, trigger control, gun distance and gun position.
The distance between the nozzle discharge opening and the object to be coated is called the spray gun distance. The smaller the spray gun distance, the greater the spray pressure, the greater the impact of the product on the air pressure, the unevenness of the coating, and the problem of excessive film thickness. The larger the spray gun distance, the smaller the spray pressure, the easier the paint is lost, and the part of the object to be coated is sprayed too little, and the coating film does not reach the specified thickness.
The spray fan surface is perpendicular to the surface of the object to be coated. When the spray gun is manually operated, the spray width cannot be excessively large, otherwise the average coating problem may occur. The purpose of the spray gun operation is always parallel to the surface of the coated object, perpendicular to the spray fan surface, the running speed is unstable, the coating thickness is not uniform, the running speed is too fast, the coating is too thin, and the running speed is too slow.
All in all, when using the spraying equipment, it is necessary to make the moderate force and the distance suitable, so that the desired coating effect can be obtained. After the construction, some of the tailing things need to be perfected, and the paint and the helping utensils are packed up. The residual paint after use should be blocked and retained, which is a problem that needs attention.
The above is the precautions for the operation of the electrostatic spray gun. Later, if you want to know more about the spray equipment, please pay more attention to us.
