The UV aging test mainly simulates the deterioration effect of ultraviolet light in sunlight on the product. It also reproduces the damage caused by rain and dew; tests are conducted by exposing the material to be tested to controlled alternating cycles of sunlight and moisture while increasing the temperature; UV fluorescent lamps are used to simulate sunlight, while also Moisture effects are simulated by condensation or spraying.
Why do UV aging test?
Ultraviolet rays are not only harmful to the human body, but also the harm to products should not be underestimated. During the processing, storage or use of materials or products, due to the influence of external factors such as heat, light, oxygen, mechanical stress, ozone, harmful metal ions, radiation, etc., physical or chemical changes occur inside the material, and the performance deteriorates. gradually lose its use value.
Types of damage caused by UV rays include fading, loss of gloss, chalking, cracking, cracking, hazing, blistering, embrittlement, loss of strength, and oxidation.
Which products need to do aging UV test?
The range of products involved is also very wide, such as: rubber, plastics and their products, coatings, paints, dyes, fabrics, printing and packaging, adhesives, metals, electronics, electroplating, cosmetics, etc.
