In the process of plastic production, due to the influence of raw materials and processing technology, the plastic surface will show different glosses. In order to measure the gloss of the plastic surface and control the appearance gloss quality of the plastic, a gloss meter can be used. Take measurements. This article introduces the method of Tri gloss meter to measure the gloss of plastics. Interested users can learn about it!

The gloss of plastic refers to the specular reflection ability of the plastic surface to light. Due to differences in raw materials and processing techniques, plastics will cause different plastic surfaces to show different luster. Under normal circumstances, there are two methods for evaluating the gloss of plastics: visual method and instrument measurement method.

The visual method is to directly observe the surface gloss of the plastic through a specific angle under a stable light source environment. This method can accurately compare the gloss difference between the sample and the standard sample, but there is no way to evaluate the specific gloss level. , and the measurement results are easily affected by the light source, the observation angle, and the observer's own conditions.

The instrumental measurement method refers to the direct measurement of the gloss of the plastic surface through a gloss meter. Users can quickly detect the gloss of plastic by following the operation and use process of the gloss meter.

During the test, the user can quickly assess the gloss of the plastic by attaching the measuring aperture of the Tri gloss meter to the surface of the plastic product, and the display screen will directly display the gloss value. However, this measurement method is a relative measurement of the specular reflectance of plastics. If there are many pores on the surface of the plastic, it will have a great impact on the measurement results.
