Spray painting is a surface treatment technology commonly used in industries such as automobiles, furniture, and machinery. The measurement of its gloss can effectively control the appearance quality and optical properties of painted products. The glossiness of spray paint has an important impact on the aesthetics, visual effect and quality control of the product. On the one hand, high-gloss spray paint can improve the appearance quality and visual effect of the product, making it more glossy and three-dimensional; on the other hand, the gloss of spray paint can also reflect its surface smoothness and coating adhesion. , thus contributing to its durability and quality stability. Therefore, measuring the glossiness of spray paint can provide an important reference for product production and quality control, help to ensure product quality and stability, and improve product market competitiveness.
Measurement steps
Preparation: Place the gloss meter on a horizontal platform and calibrate the instrument. According to the color and type of coating, select the corresponding measurement angle and light source.
Sample preparation: place the sample to be tested on a horizontal platform, and ensure that its surface is flat, dry, clean, and free from obvious damage and impurities. The size and shape of the sample should meet the measurement requirements of the gloss meter.
Measurement: Aim the test head of the gloss meter at the sample surface, touch the sample surface and press the measurement button, the instrument will send out a measurement signal and record the gloss value. Each sample was measured at least three times and the average value was calculated.
Analysis: According to the obtained gloss value, combined with coating type, thickness, surface treatment and other factors, evaluate the quality and gloss of the coating surface.
NBCHAO reminds you: During the measurement process, you should pay attention to the calibration and maintenance of the instrument to ensure its accuracy and stability, and at the same time avoid contamination and damage on the sample surface, which will affect the measurement results.
