Gloss meter to test the optical properties of the film - gloss gloss gloss

The surface of the object is oriented to select the nature of the reflection. The apparent perception of the surface of the object produced by the agitator in the spatial distribution of the reflected light. It is related to the size of the surface-directed reflection component and the sharpness of the reflected light distribution curve.

Glossiness

Use data to express the degree of gloss on the surface of the object

GB1743-79 specifies a triangular gloss meter to measure the gloss of the coating film. ISO 2813 specifies three angles (20°, 60° and 8 bend testers 5°) to suit different objects.
As we all know, the same model, from different angles, the gloss is obviously different. If you only observe the gloss of the coating from one angle, I am afraid that the gloss of all the coating samples cannot be correctly reflected. It seems that it should be closer to international standards in the future. By definition, gloss has two meanings:
First, the brightness of the reflected light,
The second is the clarity of the image of the object that can be seen from the reflected light.
In the projection gloss meter (such as the previously used coating type 1-5 type gloss meter), the two aspects of the grinding machine can be faithfully reflected. The gloss reading of the photoelectric gloss meter is a comprehensive reflection of these two aspects. In addition, the sample is slightly deformed and the test data is obviously unstable. Since the natural exposure sample is large and easy to warp, data instability is likely to occur. In the future, whether the natural exposure sample can be tested with a projection gloss meter is worth studying.
