Resistance to artificial accelerated aging

Right!

Accelerated artificial aging resistance is a method of artificially simulating climate in the laboratory to study the aging resistance of coatings.

characteristic

Artificial accelerated aging resistance a: tificia. Accelerated weathering is ^[1] based on the results of a large number of natural exposure tests, artificially simulated climate damage in the laboratory, and given certain enhancements to overcome the need for natural exposure tests Insufficient strengthening over time includes light sources (lights are replaced by ultraviolet lamps, and the ultraviolet rays are the most destructive to the material). Temperature (temperature} f also promotes accelerated aging of the paint film), and humidity 'destructive effects of ultraviolet radiation Enhancement), oxygen (oxidation promotes cracking of the paint film caused by aging, paint film loss of light) and other aspects. Strengthening includes replacing sunlight with ultraviolet light; replacing normal temperature and humidity with high temperature and humidity, and replacing air with oxygen. These can accelerate the damage to the paint film and get the results in a short time, but people _L. Force Lf rapid aging tests often It is not completely consistent with the results of the natural exposure test, but until there is no better way, this is still a shortcut to study the aging resistance of the coating film.
