company news about Electrostatic spray gun maintenance and use matters

The use of electrostatic spray gun in electrostatic spraying equipment: the structure of electrostatic spray gun is simple and easy to use, but the correct use method is required; There are many factors that affect the use of electrostatic spray guns, such as the object of painting, the coating material, and even the season. The key to the use of electrostatic spray gun is mainly: the control of the adjustment knob, the grasp of the spray distance and the spray gun moving speed, and the overlap of the adjacent coating, among which the spray distance, the spray gun operation mode and the spray pattern overlap are the three principles of spraying, and the basis of spraying technology, must be familiar with and strictly abide by.

Electrostatic spray gun is a very important equipment in the automobile painting, its structure is precise, the investment cost is also large, but if the spray gun is used and maintained properly, the painting quality and service life will be much longer. The proper use and maintenance of the spray gun is a basic skill that every painter must have. 1, spray gun use and maintenance points: (1), often check the needle valve, gasket, air valve gasket seal book whether there is leakage, leakage should be replaced in time; Oil should often be applied to the sealing gasket to make it soft and conducive to sliding. (2) The screw thread of the gun's gas cap, the adjustment knob of the amount of paint and the adjustment knob of the gas, etc., should be often oiled to ensure flexible activity; The spring of the gun thimble and air valve should also be lubricated to prevent rust and facilitate sliding. (3) Do not disassemble the spray gun at will, it should be noted that the rectangular parts should not be stuck with garbage and paint, the gas cap and nozzle should not have any damage, adjust to the initial appearance after assembly, pull the trigger to test the effect of air and paint ejection. (4) The spray gun should be comprehensively checked before use to ensure that the spray gun is in good condition before use. (5) The use of the spray gun should avoid colliding with the object being painted or falling on the ground, otherwise it will cause permanent damage and cannot be used. (6) When suspending work, the spray gun head should be immersed in solvent to prevent the paint from drying and blocking the nozzle; However, the entire spray gun should not be completely soaked in solvent, which will damage the sealing gaskets in various parts, resulting in air leakage and paint leakage.
(7), the spray gun should be cleaned in time after use, otherwise the paint channel will be blocked (especially 2K paint), it will be difficult to clean, or even can not be used again. After cleaning the spray gun, connect the paint tube and compressed air tube for test spraying, adjust the fan surface of the spray gun, and the fan Angle of the manual air spray gun is 70-80 degrees. If there is any problem, report it for maintenance in time. The most important thing to maintain the electrostatic spray gun is to clean it in time after use, which is the best preventive measure to prevent the failure of the spray gun.
