Fluorescent Brightener Anti-Yellowing Test Machine

The fluorescent whitening agent yellowing resistance tester evaluates the ability of fluorescent whitening agents to resist yellowing under light by simulating sunlight or ultraviolet radiation on samples. Its principle involves using a light source box to generate specific wavelengths of light, which are then directed onto materials coated with whitening agents to measure color difference changes. This equipment is used to assess the durability of whitening agents in materials such as paper, plastics, and textiles, aiding in quality control.
Selection
When selecting a fluorescent whitening agent yellowing resistance tester, consider the light source type and compatibility with standards, such as xenon or UV lamps; ensure the temperature and humidity control range meets testing requirements; check the sample holder size and material adaptability; verify the colorimeter accuracy and calibration methods; confirm the ease of operation and maintenance costs of the equipment; refer to common industry testing standards such as ISO or ASTM specifications.
