The inspection of the surface gloss of the coating layer has mainly used the application of the Metal gloss meter in recent years. However, due to the different effects of the different geometric shapes of the coated parts on the reflectivity, and the different interference of the coating color, it is often difficult to obtain good results. , so the user also needs to perform supplementary inspection through the visual inspection method and the sample comparison method.

The visual assessment method is an empirical assessment method. It is based on the experience accumulated by the inspectors in practice, and is evaluated by visual inspection. It is often affected by factors such as environmental illumination, the inspector's vision and experience, and it is easy to interfere and cause errors in the evaluation results.

In order to avoid various influences as much as possible, the experience gained from long-term practice: the light source of the inspection environment is specified as natural light or a fluorescent light source close to natural light, and its illuminance is 300lx (equivalent to the illuminance of a 40W fluorescent lamp at 500mm) to prevent the color of the light source. and illuminance inconsistency.

The above is the relevant content about the Metal gloss meter to detect the surface gloss of the coating, I hope it can help everyone!
