The back cover of the flat light is usually made of a sprayed plate by stamping, which has the effect of reflecting the light. The production process of sprayed plate originally evolved from the process of spraying powder after metal forming. Although the production line of powder spraying adopts continuous production, the coating process is still arranged in the form of spray guns. The sprayed board has problems such as low production efficiency, high labor intensity, large waste of paint, and uneven thickness of the coating film. Therefore, the sprayed board has basically been replaced by the film-coated board production line. Therefore, the back cover of the flat panel lamp now chooses the film-coated steel plate.
The laminated plate is a laminated steel plate formed by processing various color films onto the substrate. The performance of the laminated plate is good. Even after various experiments, the color film and the steel plate will not fall off, and the processing performance is good. Compared with color-coated boards, it is better to make a reflective board with a film-coated board, and the reflective effect is better. It can be continuously produced and has a large production volume.
The reflector made of the film-coated board not only has the characteristics of being easy to process and form, and easy to produce, but also has a high reflectivity, which is beneficial to be applied to the lampshade.
