Description

A UV fluorescent aging test chamber

technical field

The utility model relates to the technical field of test equipment, in particular to an ultraviolet fluorescence aging test box.

Background technique

The working principle of the UV fluorescent aging test chamber is to simulate the outdoor environment through ultraviolet light irradiation, water spray and water vapor condensation. After the sample is put into the testing machine for a certain period of time, the aging phenomenon of the product after a long period of time in the outdoor environment can be simulated.

However, the output light energy of the ultraviolet lamp will gradually attenuate during use, making the radiation intensity lower than the specified range of the test standard, which will have a great impact on the test results, and the unstable working power will shorten the working life of the ultraviolet lamp . However, the existing ultraviolet fluorescent aging test chamber cannot automatically adjust the power of the ultraviolet lamp. Moreover, most of the UV aging systems currently on the market conduct aging experiments directly under the irradiation of light sources. The wavelength range of the radiated light is not very specific, and the operation is complicated and cannot meet the requirements of special experiments. For example, the photocatalysis experiment under different ultraviolet radiation power densities requires that the radiation power density of the sample be adjustable during the experiment; another example is the aging test of vulcanized silicone rubber in a specific spectral range, which requires the use of ultraviolet light with a certain wavelength range to accelerate silicon vulcanization. Rubber aging, and the UV aging test chamber of the prior art cannot meet the requirements of special experiments because the power density and spectral composition of the light source cannot be adjusted.

In addition, most of the ultraviolet fluorescence aging test chambers are not equipped with observation windows. When users need to observe the situation in the test chamber, they need to open the chamber door, which is quite inconvenient, and the strong light in the test will hurt the user's eyes.

Therefore, there is an urgent need to provide an ultraviolet fluorescence aging test chamber to solve the deficiencies in the prior art.
