Spraying is an important measure to improve the surface quality of workpiece, but there are still many irregular practices in the actual operation process, which have a negative impact on the spraying processing quality to varying degrees. Here are some examples of how to solve these problems.
In the process of painting, it is very important to process the workpiece surface. Once the surface treatment is improper, not only the surface quality is poor, but also the spraying effect is affected. In order to avoid this situation, the traditional wet grinding process is usually used for the surface treatment of workpieces.
Unexpectedly, the surface treatment process has brought many hidden quality problems in the spraying process, and gradually appeared. In this case, it is recommended to use the full dry grinding method for surface treatment. The actual operation is to grind the surface with pneumatic tools or electric tools, which can not only effectively absorb the dust generated in the operation process, but also improve the work efficiency and better effect.
In order not to affect other parts that do not need spraying, operators usually cover them with newspapers. However, it is important to know that the lead ink in the newspaper may penetrate into the coating surface during high-temperature spraying, resulting in defects on the coating surface and reducing the overall beauty.
In order to prevent this non-standard operation, the painting processing personnel must use anti-static shielding paper to shield the non operating part of the vehicle body, so that the painting processing not only leaves traces on the surface, but also the clean and tidy working environment is one of the effective measures for painting quality.
