5.5补漆施工
(1)补金属底漆。缺陷处漏中涂的补漆方法。首先对缺陷处80%的部位喷涂底漆,晾干1~2min,然后从多角度对缺陷部位100%喷涂,从多方向消除发花。补金属底漆是最关键的一道工序,喷涂过厚,漆膜颜色易发暗;喷涂太薄,漆膜易发花。为此,应首先将喷枪调节好:喷涂压力为0.05MPa、喷幅为5~15cm、距离为30~40cm,喷涂角度为90°。雾 相似文献

Because of the importance of metallic paints particularly in the automobile industry, there is a need for colour measurement techniques which show a high correlation with visual judgments. The present study uses recently developed spectrophotometers with variable geometries to optimize this correlation. Visual and instrumental data have been analyzed by means of statistical techniques. The investigations have led to the conclusion that three different geometries are sufficient to describe the optical behaviour of metallic paint films, provided that the geometries are well distributed with respect to the angle between the direction of observation and the direction of the specular component. In addition to this measurement technique a calculation procedure has been developed that yields judgments that highly correlate with visual judgments. 相似文献

The gonioapparent lightness of a metallic paint system depends strongly on the 3D microstructure of the platelet-containing basecoat layer, and on the platelet roughness. Current optical models which are used to simulate the paint’s appearance, however, ignore the multi-scale and multi-dimensional microstructural features, which limits their predictive power. Here, we describe a hybrid, ray-wave optics model for metallic paints. This model incorporates the ray-optics of the 3D platelet microstructure and the wave effects that result from the surface roughness of the platelets. This model is used to link the roughness to the reflection lobes of the aluminum platelets, and to the gonioapparent lightness of the paint system. Predicted lightness values from our model matched, at most viewing angles, measurements from physical paint samples. This model can be used to explore the effect of platelet surface roughness on the lightness of the complete paint system and predict the appearance of paints with different platelet microstructures. 相似文献
