For the professional who is doing the instrument, the principle of the Xenon weathering test box is not difficult, it is simply entry-level content, but for those who have just entered the line, this is not easy to instill knowledge.
Xenon lamp aging weathering test chamber uses artificially weathered or artificially exposed radiation to the coating by a filter-filtered xenon arc lamp. The purpose is to enable the selected properties to be produced after the coating is subjected to a certain exposure radiant energy. A certain degree of change, or the exposure radiation energy required to bring the coating to a certain level of talent. The performance selected for monitoring should be an important performance of the coating in practical applications. The performance of the exposed coating can be compared to the performance of an unexposed coating (comparative sample) that is also prepared, or to a coating (reference) of known properties that are simultaneously exposed.
In the natural climate, the sunlight exposure of the Xenon weathering test chamber is considered to be the main reason for the aging of the coating, and the principle of exposure radiation under the window glass is the same. Therefore, for artificial climate aging and artificial exposure radiation, simulating solar radiation is crucial.
