Sculpture Surface Gloss Requirements and Measurement
1. What does the surface gloss of a sculpture mean?
It is often said that the surface gloss of a sculpture is the reflection under the condition that its surface is rough. The reflected light has a clear directionality, which is generally called specular reflection. Use this property in optical materials to achieve a variety of applications. However, the surface of most materials is not completely smooth, so when the light hits the rough sculpture surface, a considerable diffuse reflection occurs.
2. Sculpture surface gloss requirements
Different sculpture products have different requirements for their surface gloss. Manufacturers need to strictly control the gloss quality of products according to customer requirements.
For urban sculpture, it is an art exhibition that records the history and culture of the city. In order to obtain a better appearance, strict requirements are required for its surface gloss and color. Whether the gloss is too high or too low, it will affect the overall display effect. To accurately evaluate the surface gloss of a sculpture, a special instrument is needed for measurement.
3. Gloss tester measures the surface gloss of sculptures
To measure the surface gloss of a sculpture, a gloss tester is used. Most gloss testers measure the specular reflectance of the object surface, that is, the specular gloss.
Linshang LS192 gloss tester has real-time temperature compensation function. No matter what temperature environment, it can ensure the stability of the instrument, making the measurement results stable and reliable.
When using a gloss tester to control the surface gloss quality of a sculpture, users need to specify the measurement angle used by the instrument. Customers use the same instrument to measure and then compare the measurement results. The general angle on the market is a 60-degree angle. Like the general-purpose 60-degree gloss tester LS192 from Linshang Technology, the measurement range reaches 1000GU. High-gloss and low-gloss materials can be tested because gloss is a relative value. When there is no uniform standard in the industry, the LS192 gloss tester can be used for testing. If the industry has a uniform standard, it is best to use the same angle gloss tester for testing. Therefore, when selecting the measurement angle, you should choose differently according to different situations.
