Multifunctional composite environment test device

Abstract

A multifunctional composite environment test device is composed of a main box body, a function box and a control system. The main box body and the function box are provided with a salt spray test system, a dampness-heat test system, an ultraviolet test system, a spray test system and a wetting test system. The device can provide a nine-factor composite environment of salt spray, dampness-heat, dryness, high temperature, low temperature, spray, ultraviolet, wet and dry alternating, and baking. Through the coupling design and the coupling control of the test box, the composite test of the abovevarious functions and the superimposed cycle test can be carried out. The device can comprise a mobile rain matrix, a telescopic humidity measurement system, a transmission type dry-wet alternating system and the like to achieve a variety of composite environments, thereby effectively avoiding the mutual interference and cross contamination problems between various combinations of factors.

Description

technical field [0001] The invention relates to a multifunctional composite environmental test device, which belongs to the field of service performance testing of new materials. Background technique [0002] The environmental test chamber is an accelerated test device used to realize the indoor simulated environment, and is used to study the corrosion aging behavior and mechanism of materials and products in use and storage environments. Compared with natural environment experiments, a large amount of data can be obtained in a short time, so it has been widely used. The main environmental test chambers include salt spray test chambers, temperature and humidity test chambers, weekly immersion test chambers, weather resistance test chambers, etc. [0003] However, the above-mentioned environmental chamber can only meet the accelerated test of a single corrosion aging factor. Compared with the ever-changing natural environment, the investigation of a single factor is not enou...

Problems solved by technology

At the same time, the existing composite environmental test chamber does not avoid the cross-contamination problem between the combinations of various factors, such as the influence of salt spray on temperature and humidity measurement, the pollution of salt spray on the surrounding immersion solution, the pollution of spray water droplets between combination switching, and the pollution of Corrosion of the medium to the evaporator, etc.
