Operation Of The Spray Gun

Operation of the spray gun

During the spraying operation, improper operation of the spray gun will affect the spraying effect of the product. The good spraying effect is shown in: 1. The coating is evenly distributed. 2. The coating should not be too thick or too thin. A few things to pay attention to when spraying:

The distance between the nozzle outlet and the object to be coated is called the gun distance. The smaller the gun distance, the greater the spray pressure, the greater the impact of the air pressure on the product, and the unevenness of the coating, resulting in the problem of overly thick application. The larger the gun distance is, the smaller the spraying pressure is, and the paint is easily lost, so that the sprayed part of the object to be coated is too small, and the coating cannot reach the specified thickness. The spraying fan surface is vertical to the surface to be coated. When manually operating the spray gun, the spray width should not be too large, otherwise there will be a problem of even coating. The purpose of spray gun operation should always be parallel to the surface of the object to be coated and perpendicular to the spraying fan surface. All in all, when using spraying equipment, it is necessary to achieve moderate strength and appropriate distance, so that the desired coating effect can be obtained. After construction, some finishing things also need to be improved, and paint and help appliances are cleaned up. , the residual paint after use should be blocked and retained. This is a problem that needs attention.

The essentials that need to be paid attention to in the operation of the spray gun include: the moving speed of the spray gun, the control of the trigger, the distance between the gun and the position of holding the gun, etc. The following is an explanation for you:

1. The moving speed of the spray gun.

During the spraying operation, the moving speed of the spray gun has a great influence on the coating effect.

1. If the manual spray gun moves too fast, the surface coating of the object to be coated will be thin, which will appear dry, poor leveling and rough;

2. If the moving speed of the manual spray gun is slow, the coating film on the surface of the object to be coated must be very late, and it is easy to cause sagging.

3. The ideal moving speed of the spray gun is that after the spraying is finished, the surface coating of the object to be coated is full, uniform and wet. This requires operators with certain spraying experience to control.
