Fluorescent / Accelerated UV Testing

Application area

The UV lamp weathering test chamber uses fluorescent ultraviolet lamps as the light source, and appropriately controls the temperature and humidity to periodically produce condensation on the samples to fully obtain the results of the damage of sunlight, humidity and temperature on polymer materials (material aging) Including fading, loss of gloss, strength reduction, cracking, peeling, chalking and oxidation, etc.

The fluorescent ultraviolet rays of the ultraviolet lamp can reproduce the influence of sunlight, and the condensation and water spray system can reproduce the influence of rain and dew. During the entire test cycle, the irradiation energy and temperature are controllable. A typical test cycle is usually a dark and humid condensation cycle under high temperature ultraviolet light irradiation and relative humidity at 100%; typical applications are paint coatings, automotive industry, plastic products, wood products, glue, etc.
