Xenon Test Chamber Supplier and Dealer in India

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 a selected property after a certain radiant exposure H, and/or the radiant exposure required to produce a certain degree of ageing. The properties selected for monitoring should preferably be those important for the practical use of the coatings. The properties of the coatings exposed are compared with those of unexposed coating prepared from the same 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 exposure apparatus is already known (reference specimens).

Xenon lamp is full of xenon and sends out light because of xenon discharge. The energy distribution of spectrum through this way is very close to sunshine, and its color temperature is near 6,000 K. Furthermore, xenon lamp has a stable character; its spectrum energy distribution won't change at all within the limited lifetime. This is because its energy distribution among continuous spectrum part doesn't have any relation to input power of lamp. As a special light source, xenon lamp has a good consistency for electric parameters, and it is easy to light; once light on, it can output a steady light energy at once. Furthermore, during working, the electric parameter won't be influenced by any external conditions.

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 are generally applied in the fields of paint and coatings, automotive industry, plastic, wood, glue, etc.

BGD series Xenon Light Accelerated Aging Test Chambers (hereinafter referred to as B-SUN) use Xenon lamps as artificial light source and can modify the full spectrum sunlight. Controlling the temperature and humidity, its inner 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, cracking, flaking, chalking, and oxidation).

Based on sample holder type, B-SUNs are divided into flatbed type and rotating drum type.

BGD 860 is a powerful, highly cost-effective, easy to use and convenient to maintain xenon test chamber. It uses an imported air-cooled xenon lamp and relevant daylight filter to simulate a more realistic and better full spectrum sunlight. This ensures that the test results obtained from the laboratory have a perfect correlation with outdoor applications. Furthermore, the sample holder is designed with a special rotating drum to ensure each sample can obtain the same and uniform irradiance during the whole test.

BGD 860 Xenon Test Chamber can meet all standards requirements from different fields; it can hold 22 pieces of samples, not only has spray function, but also can control the relative humidity of the working room.
