　　Spray gun painting

　　1. Preparation and commissioning of spray guns

　　Before using a spray gun, make sure it is clean. Check whether the various parts of the spray gun are working properly, such as whether the spray gun nozzle is blocked. For different types of spray guns, such as gravity spray guns and siphon spray guns, they should be commissioned accordingly according to the type of paint and the desired painting effect. For gravity spray guns, since the paint cup is at the top, the paint flows into the spray gun nozzle by gravity. Pay attention to the firmness of the paint cup to avoid shaking or falling off during the painting process. For siphon spray guns, check whether the siphon device is working properly to ensure that the paint can be stably sucked into the spray gun nozzle.

　　Adjust the air pressure of the spray gun according to the viscosity of the paint. Generally speaking, if the paint is thin, the air pressure can be set at 2-3 bar; if the paint is thick, the air pressure may need to be increased to 3-4 bar. At the same time, adjust the spray width, the size of the spray width determines the coverage area of the paint. For large areas of aluminum, the spray width can be set at 15-20 cm; for small areas or areas that require precise painting, the spray width can be reduced to 10-15 cm.

　　2. Painting operation

　　When starting to paint, keep the spray gun perpendicular to the aluminum surface and the distance controlled between 15-20 cm. This distance is the key to ensuring a uniform paint layer. If the distance is too close, it is easy to cause the paint layer to be too thick and produce sagging; if the distance is too far, the paint mist will disperse, resulting in a thin and uneven paint layer.

　　When moving the spray gun, keep a constant speed, which is generally controlled between 30-60 cm/second. You can use a horizontal or vertical movement method, such as starting from one end of the aluminum surface, moving the spray gun horizontally at a constant speed to the other end, and then moving it vertically in the next line, so that the entire aluminum surface can be painted evenly.

　　When spraying multiple layers of paint, the drying time between each layer of paint must be strictly controlled. This depends on the type of paint and environmental conditions. For example, in an environment with a temperature of 20-25°C and a humidity of 40%-60%, the drying time between each layer of acrylic paint is about 15-30 minutes; polyurethane paint may take 30-60 minutes. While waiting for drying, make sure that the painted surface is in a well-ventilated environment to prevent dust and other impurities from falling on the undried paint layer.
