| Summary: | 碩士 === 東南科技大學 === 機械工程研究所 === 106 === The phenomenon of paint film formation on the surface of the paint will occur when the baking equipment of car sprayers reaches the operating temperature. This article is to compare the characteristics of car spray pieces by the flow field structure and effects of new/old spray chamber, as also to discuss and study the quality improvement of products quality. It examines the parameters such as brightness, hue, chroma, and film thickness. And compare the differences of the parameters in the brightness, hue, chroma and film thickness between the old and new spray chamber. The experimental data show that for the economic effect, the data of pearl-white color (070) in the old/new furnaces (lightness, hue, chroma) are quite different, and the data in the new spray chamber has excellent data. The pieces should be used as much as possible in the new spray chamber. The new furnace is unable to achieve the intended effect in dark-colored painted parts. At this time, the dark-colored painted pieces should be used as much as possible in the old spray chamber to reduce the load on the new spray chamber.
