UV accelerated aging testing machine with humid condensation environment and water spray system

In many outdoor environments, materials can be kept moist for up to 12 hours per day. Research has shown that the main factor causing outdoor humidity is dew, not rainwater. GUV simulates outdoor moisture erosion through its unique condensation function. In the condensation cycle during the experiment, the water in the reservoir at the bottom of the testing chamber is heated to generate hot steam, which fills the entire testing chamber. The hot steam maintains the relative humidity in the testing chamber at 100% and maintains a relatively high temperature. The sample is fixed on the side wall of the testing chamber, so that the testing surface of the sample is exposed to the ambient air inside the testing chamber. The outward side of the sample exposed to the natural environment has a cooling effect, resulting in a temperature difference between the inner and outer surfaces of the sample. The occurrence of this temperature difference causes the sample to always have liquid water generated by condensation on its testing surface throughout the entire condensation cycle.

Due to outdoor exposure to moisture for up to ten hours a day, a typical condensation cycle typically lasts for several hours. GUV provides two methods for simulating humidity. The most commonly used method is condensation, which is the best way to simulate outdoor moisture erosion. All GUV models are capable of running condensation cycles. Because some application conditions also require the use of water spray to achieve practical results, some GUV models can operate both condensation cycle and water spray cycle.

For certain applications, water spray can better simulate the environmental conditions of final use. Water spraying is very effective in simulating thermal shock or mechanical erosion caused by temperature fluctuations and rainwater erosion. Under certain practical application conditions, such as sunlight, when the accumulated heat rapidly dissipates due to sudden showers, the temperature of the material will undergo a sharp change, resulting in thermal shock, which is a test for many materials. GUV's water spray can simulate thermal shock and/or stress corrosion. The spray system has 12 nozzles, with 6 on each side of the testing room; The sprinkler system can run for a few minutes and then shut down. This short-term water spray can quickly cool the sample and create conditions for thermal shock.
