The CRS-XD xenon lamp weather resistance test chamber
Xenon lamp weather resistance test chamber basic principles:
The weathering test screening in the research and production process formulations to optimize product composition, is also an important element of product quality inspection Applied Materials such as paints, plastics, aluminum panels, as well as automotive safety glass and other product standards are required to do the weathering test.
The main factor is the cause of material aging sunlight, temperature and humidity. Weathering test chamber can simulate the harm caused by the sun, rain and dew. Weathering test chamber with xenon lamp to simulate the effects of sunlight, rain and dew condensed moisture simulation to test the material being tested is placed in a certain temperature cycle of alternating light and moisture program, with a few days or a few weeks time to reproduce harm Outdoor months or even years. Artificial accelerated aging test data can assist in the selection of new materials, transformation of existing materials, as well as how the evaluation formula changes affect the durability of the product.
Xenon lamp weather resistance test chamber main features:
1. Ventilation cooling device: test chamber temperature ventilation cooling system automatically by temperature control.
Rain system: the rain system pumps, time relay nozzle part adjustable spray cycle.
Control blackboard thermometer wireless transmission technology, improve control accuracy.
4 fiber transmission measuring the radiation intensity of the xenon lamp to avoid problems lead to measurement error due to temperature reasons.
Xenon lamp cooling water refrigeration units, water recycling, reduce the costs of operation and maintenance of equipment.
The 6 sample frame sample frame to 1r/min speed rotating around the light source installed in the sample holder blackboard thermometer the BPT or black standard thermometer BST.
Timing device: To record the time of each test, the device has a timer on the operation panel, control equipment time, timing device that automatically shut down.
Protection device: in order to make the xenon arc lamp can work normally, without damage, by the equipment in addition to the xenon arc lamp is lit on the circuit does not work (i.e., cooling water and cooling water chain xenon arc lamp is not lit) and not normal cooling water failures occurred during operation, the xenon lamp automatically turns off, the whole machine stops working protection facilities.
