Different from the conventional aluminum veneer, the shape of the profiled aluminum veneer has a high degree of irregularity and complexity, such as curved aluminum curtain wall veneer, lacquered aluminum curtain wall veneer, etc., curved column aluminum veneer spraying When some places may not be sprayed or the effect is not as expected, what are the precautions when spraying the profiled aluminum veneer?
In the curtain wall aluminum veneer industry, electrostatic spraying is basically used in the spraying process. This is because the electrostatically sprayed outer wall aluminum veneer steel skeleton content is much better than the air gun painting, and has many advantages, such as high spraying efficiency and cost saving. The quality of the paint film is very high, almost reaching no dead angle coverage. However, during the spraying process, it is especially important to pay attention to the changes in the temperature and humidity of the paint booth, otherwise the quality of the paint film will be affected.
When spraying a profiled aluminum veneer, first spray it as usual. Although electrostatic spraying can theoretically achieve no dead angle spraying, the curtain wall shaped aluminum veneer has an irregular shape due to its irregular shape. In the actual operation process, the actual effect of the paint on the board surface is difficult to achieve the expected result, so after the completion of the spray, it is necessary to carry out a careful inspection, and the appropriate artificial touch paint should be carried out in the insufficient place to achieve better results.
Because it is a special-shaped plate, this requires the technical workers of the aluminum veneer manufacturer's sheet metal line to understand the drawing carefully, because the position of the hole may change after the bending, so it is easy to make mistakes if you are not careful.
In addition, in the spraying process of the shaped punched aluminum veneer, it is also necessary to take care of it. It is impossible to use electrostatic paint spraying on the special-shaped plate. The main use is manual spraying, so the skilled workers are required to be experienced and skilled. Only in this way can the color of the shaped punched aluminum veneer and the related quality of the paint film and the like be guaranteed.
