Gold plating is a commonly used surface treatment with a wide range of uses, but the measurement of its gloss is very important. Measuring gloss ensures that gold-plated surfaces are smooth, uniform and highly reflective, improving their appearance and quality. Gloss measurement can be realized by the intensity of reflected light, and its unit is GU (Gloss Units). Before measurement, it is necessary to ensure that the test environment is not disturbed by external light sources, and an appropriate measurement angle and light source should be used. By measuring the gloss of a gold-plated surface, it is possible to assess its quality and, if required, take appropriate measures to improve its surface quality.
Detection method
Gloss meters can also be used to measure the surface gloss of gold-plated surfaces. The following are the steps for testing the glossiness of gold-plated surfaces with a gloss meter:
Prepare the sample: Take a flat sample from the gold-plated side to be tested and make sure there are no scratches or stains on the surface of the sample.
Adjust the gloss meter: According to the operating instructions of the gloss meter, adjust the instrument to the appropriate test mode and light source.
Place the sample: put the gold-plated surface sample on the gloss meter test bench, and calibrate the sample according to the instrument instructions.
Run the test: Start the gloss meter and follow the instructions in its operating instructions to run the test. During the test, it should be ensured that the instrument and the sample are in a stable state without moving or shaking.
Record the results: After the test is completed, the measurement results are recorded and analyzed. Generally, a gloss meter will provide a digital readout that represents the gloss value of the sample. Higher numbers indicate higher gloss.
Repeat the test: To verify the accuracy of the results, the test can be repeated several times until consistent results are obtained.
NBCHAO reminds you: the glossiness of the gold-plated surface is greatly affected by environmental factors, oxidation and other factors, so the freshness and dryness of the sample should be kept as far as possible before the test, and the test conditions should be strictly controlled to ensure the test accuracy of results
