The UV xenon lamp weather resistance composite testing machine can simulate the hazards caused by sunlight, rain, and dew. It uses xenon lamps to simulate the effect of sunlight exposure and condensed moisture to simulate rain and dew. The tested material is placed in a cyclic program of alternating light and moisture at a certain temperature for testing. It takes several days or weeks to reproduce the hazards that occur outdoors for months or even years. Artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formulation affect product durability.

Natural environments such as light, humidity, temperature, and rain are all factors that cause material aging. In order to evaluate the weather aging resistance of materials, a UV xenon lamp weather resistant composite testing machine was developed. The device can reproduce the hazards that occur outdoors for months or even years in a matter of days or weeks. Using condensed moisture to simulate rainwater and dew, using xenon lamps to simulate the effect of sunlight exposure, the tested material is placed in a cyclic program of alternating light and moisture at a certain temperature for testing. Test conditions applicable to continuous illumination testing:

One Spray cycle of UV xenon lamp weather resistant composite testing machine:

The spraying cycle used in the experiment should be agreed upon by the relevant parties. But it is better to choose the following water spraying cycle: each spraying time: 18m in ± 0.5min, and the water free time between two sprays: 102m in ± 0.5min.

II Blackboard temperature of UV xenon lamp weather resistant composite testing machine:

Choose the following two black standard temperatures as reference for testing: 65 ° C ± 3 ° C or 100 ° C ± 3 ° C. If water spray is used, the temperature should be kept constant during the waterless cycle. If the thermometer cannot reach the specified temperature, the high temperature reached during the anhydrous period should be stated in the test report. Even if the device operates in an alternating manner, the black standard thermometer should measure continuously. If a blackboard thermometer is used, the type, placement method, and selected operating temperature of the thermometer should be specified in the test report.

III Relative humidity of UV xenon lamp weather resistant composite testing machine:

The relative humidity used in the experiment should be agreed upon by relevant parties But it is better to choose either of the following conditions: (50 ± 5)% or (65 ± 5)% (note: because the temperature of samples of different colors and thicknesses is different, the relative humidity inside the test chamber may not necessarily be equal to the relative humidity of the air adjacent to the surface of the sample)

The UV xenon lamp weather resistance composite testing machine, also known as the "xenon lamp aging test chamber", is divided into three types according to testing standards and methods: air-cooled xenon lamp, water-cooled xenon lamp, and desktop xenon lamp. The difference lies in the temperature, humidity, accuracy, time, etc. of the test. It is a testing instrument in the aging test chamber series. It is a comprehensive environmental testing equipment that can simulate xenon arc lamps with full sunlight spectrum to reproduce destructive light waves in different environments. It is suitable for simulating sunlight accelerated aging tests on samples of electrical and electronic products, plastics, rubber, and colored building materials. The test chamber is divided into two working structural forms: water-cooled and air-cooled.
