The use method and operation elements of air spray gun

1 use method
1.1 according to the process requirements to adjust the air pressure (generally about 0.5MPa) coating pressure (generally 0.15 to 0.25MPa)1.2 the air pipe is connected to the compressed air supply station1.3 the paint delivery hose is attached to the paint supply station1.4 Attach the compressed air access tube to the spray gun air tube connector1.5 the paint delivery hose is attached to the spray gun coating tube interface1.6 Open the valves of the paint supply station and the compressed air supply station and adjust the spray fan by adjusting the component rod2 operating elements
2.1 spray distance fromspray distance refers to the spray gun's nozzle to the distance from the coatingStandard spray distance is: large spray gun 20 to 30cm, small spray gun 15 to 25cm, air atomized portable electrostatic gun 25 to 30cmAt present, Chery Automobile Co., Ltdcoating using air spray distance of 15 to 25 cmSpraying distance is too close, the unit time formed the coating film thick, easy to produce flow hanging, spraying distance is too far, thin coating film, paint loss increases, serious film will not have luster2.2 Gun operation mode
the operating status of the spray gun includes the angle of the spray gun and the surface of the coating and the speed of the spray gunThe spray gun should be kept at right angles and parallel running on the surface of the coated object, and the speed of the gun's movement is generally adjusted in the range of 30 to 60cm/s, and is constant If the spray gun is tilted and the arc trajectory runs or the running speed is variable, the coating film with uniform thickness can not be given, which can easily lead to the abuse of the film to produce flowering, orange peel and hanging and other ills 2.3 spray pattern of the tower width spray pattern of the tie width should be maintained a certain (generally 1/4 to 1/3 of the effective spray pattern range) If the connection width is variable, the film thickness is not uniform, the coating film is prone to defects
