Gloss is one of the important indicators to evaluate the surface quality of marble, granite and other stone materials. Gloss meter is widely used in marble and granite gloss testing.
Application meaning
The glossiness of marble refers to the reflective ability of its surface, that is, the degree of brightness of the surface. Measuring the gloss of marble can help determine the quality and appearance of the marble surface. If the glossiness of the marble surface is uneven or does not meet the requirements, it will cause problems such as the marble surface is not smooth enough, not bright enough, and difficult to clean, which will affect the service life and aesthetics of the marble. Therefore, measuring the gloss of marble can check the uniformity and quality of the marble surface, ensure that the marble meets the requirements, and improve the appearance and service life of the marble. In addition, gloss is also an important indicator of marble surface treatment process. For some marble products processed by special processes, such as polishing and grinding, it is more necessary to measure the influence of gloss.
experiment procedure
The measurement steps are described below:
Sample treatment: Clean the surface of the stone sample to be tested, remove surface impurities, and then let the surface dry.
Instrument preheating: Turn on the power of the gloss meter and perform preheating. Preheat according to the specified time of different instruments.
Instrument Calibration: Perform instrument calibration according to the instrument instructions. Generally, the instrument is measured and calibrated on a clean glass standard to ensure accurate measurement results.
Measurement operation: Place the sample on the instrument smoothly to avoid sample movement and scratching the surface. Select the measurement mode and perform the measurement. Generally, the triangulation method is used to align the probe head of the instrument with the sample surface so that the light is incident and reflected perpendicularly. At this point, the instrument can output the gloss value of the sample surface.
Data processing: According to the data output by the instrument, statistics and analysis are carried out. In general, the average gloss value of the sample, as well as the standard deviation and deviation of the gloss value can be calculated.
NBCHAO reminds you: During the measurement process, the interference of external light should be avoided as much as possible to ensure that the measurement environment light is relatively stable. In addition, the operation instructions of the instrument should be followed to ensure the accuracy and reliability of the measurement results.
