mit Xenon-Bogenlampe

Artificial weathering of coatings or exposure of coatings to filtered xenon-arc radiation is carried out in order to obtain the degree of change in as elected property after a certain radiant exposure H, and/or the radiant exposure which is required to produce a certain degree of ageing. The properties selected for monitoring should preferably be those which are important for the practical use of the coatings. The properties of the coatings exposed are compared which those of unexposed coating prepared from the same coating materials at the same time and in the same way (control specimens)or with those of coatings exposed at the same time whose behavior during testingin exposure apparatus is already known (reference specimens). Xenon Lamp light can emulate the effect of sunshine,while water spray system can emulate the effects of rain and dew. During the test, radiation energy and temperature are controllable. A typical test cycle generally carries out under strong irradiation of Xenon light and periodic precipitation. These tests generally appliedin the fields of paint and coatings,automotive industry, plastic, wood, glue,etc… SANWOOD Xenon lamp aging test chamber（here in after referred as B-SUN）use Xenon lamps as artificial light source, and canmodify the full spectrum sun light. Controlling the temperature, humidity .It sinner temperature and humidity can be properly controlled to obtain the periodic precipitation on the sample for fully evaluating the damaged factor caused by sunlight, moisture and temperature (materials aging phenomenon includes fading, disluster, intensity reduction, racking, flaking, chalking, and oxidation).
