技能大赛（Skills contest） Iii. Noun interpretation 1. Metallic coating: the coating on the surface of the object is coated with the metallic pigment such as aluminum powder, and the coating of the coating with metallic luster coating is obtained. 2, air spray: compressed air is to rely on air export to produce negative pressure, make the paint coating automatic outflow and under the impact of the compressed air flow mixing is fully atomized, paint mist in the air helped toward the workpiece surface and deposition coating method. 3, electrostatic spraying, electrostatic spraying, coating particle impact of ionized air and take charge, due to the atomized sufficiently, surrounded by electric field, the priming paint fog will effectively, high adhesion and is deposited on the surface evenly. 4. Flow hanging: the phenomenon of vertical or oblique surface coating on the surface of vertical or oblique curve during spraying and drying is referred to as the flow hanging. 5. Poor leakage: due to thin coating, insufficient film thickness or poor covering of paint, the background can be seen. 6. Sandpaper grain: after finishing and drying the surface paint, it will be able to clearly see the abrasive print of the sandpaper and affect the appearance of the coating. 7. Powder: the coating surface is affected by the sunlight, oxygen and moisture in the atmosphere, and it is aged in powder form, and the appearance of colored powder can be seen on the surface. 8. Granule: on the coated surface of the drying, a relatively hard particle or small heat rash that can be seen by the naked eye. 9. Color difference: the color phase of the coated film after coating, the brightness, the color degree and the standard with the difference of the occasion or with the surrounding. 10. Bad glue coating: during the process of coating, it produces leakage, fracture, crack, irregular, stain and other defects. Loss of light: due to the bad coating, the gloss of the coating and the changing luster of the ti
