When the epoxy powder automatic electrostatic spraying equipment is sprayed, the liquid electrostatic spray gun is often used to spray the surface of the workpiece, and the phenomenon of poor atomization often occurs. The external factors have a great influence. The daily maintenance work is not done well. It will also add to our work. problem.
Using low-purity compressed air, the impurities in the compressed air cause major mistakes in spraying and cannot achieve the desired effect. Optimum air purification is an absolute must to achieve the best spray results. It is necessary to install a filter. Compressed air inlet adjustment of air pressure is also a feasible method.
Second, liquid electrostatic spray guns are often soaked in dirty old thinner. The atomization holes and air passages of the spray gun are often blocked by the residue of the paint. These solid particles slowly accumulate and eventually block the entire air passage. Therefore, when cleaning by hand, use a brush or towel dipped in solvent to clean carefully, and do not allow solid particles to pass through the air intake atomizing holes or enter the interior of the spray gun.
Often the wrong tools (eg paper clips and wire brushes) are used when cleaning nozzles. As a result, the spray type and atomization effect are destroyed, and the nozzle can only be replaced to continue to use. In order to achieve careful cleaning, especially the air cap and other parts, the cleaning tool (small brush) that comes with the spray gun should be used to ensure that the quality of the spray gun can be maintained for a longer time.
The front and rear gasket surfaces of the gun are often damaged by tools. In order to ensure the tightness of the spray gun, the special tools included in the box should be used for disassembly and assembly operations. The matching nozzle assembly is the decisive factor in achieving the best spray results. Spray guns purchased are stocked with spare nozzle parts and are precisely adjusted and tested to ensure optimum accuracy. Mixing different types of nozzle assemblies can affect spraying results and cause poor atomization.
