What is a UV condensation aging test chamber?

What is the UV condensation aging test box? It uses artificial UV lamps to simulate outdoor UV to test the actual anti-aging effect of plastic or plastic products. The reason for the aging of plastics is mainly due to the weak points in the structure or components that are easy to cause aging, such as unsaturated double bonds, carbonyl groups, branched chains, hydroxyl groups at the end, and so on.

External or environmental factors are mainly sunlight, rain, moisture, oxygen, high heat, radiation, seawater, salt spray, and so on. Ultraviolet condensation aging test chamber It is a weather resistance equipment that mainly evaluates the effects of solar radiation, heat and humidity on plastics. The photodegradation of outdoor plastic products is mainly caused by ultraviolet light. According to different test conditions, Aipei Technology has 2 different UV lamps to choose from.

The fluorescent ultraviolet lamp of the plastic ultraviolet aging test box can simulate the important short-wave ultraviolet light in sunlight and reproduce the aging of the physical properties of plastic materials caused by light. Of course, Aipei also has many aging test equipment suitable for plastics, such as high temperature, high heat and high humidity box, salt spray test box, xenon lamp aging test box and many other equipment for customers to choose to buy or customize.

The UV condensation aging test chamber is equipped with a spray type: the spray type can simulate the effects of rain, such as thermal shock and water erosion. Under certain practical application conditions, such as sunlight, when the accumulated heat is rapidly dissipated by a sudden rain shower, the temperature of the plastic can change dramatically, creating thermal shock, which is a type of thermal shock for many materials. test.

The water spray of the UV weathering chamber can simulate thermal shock and/or stress corrosion. What is a UV condensation aging test chamber Plus condensation method: The condensation method is a suitable method for simulating outdoor moisture erosion, and has many applications. Condensation cycles can be run on all Apex 3-function plastic UV weathering chamber models. In many outdoor environments, plastic can be wet for up to 12 hours a day.

Research has shown that dew, not rain, is the main contributor to this outdoor wetness. Aipei UV aging test chamber simulates outdoor moisture erosion through a unique condensation function. During the condensation cycle, water vapor is generated by heating the water pan at the bottom of the tester. Hot water vapor keeps the chamber at 100% relative humidity at higher temperatures.
