Equipment usage:
This experimental equipment simulates the damage caused by solar ultraviolet light, and conducts weather resistance testing on the tested material by exposing it to controlled high temperature light. It uses ultraviolet lamps to simulate the radiation effect of sunlight, and simulates dew and rain through condensation and water spraying. In just a few days or weeks, the ultraviolet irradiation equipment can withstand the damage that takes months or even years to occur outdoors, including fading, color changes, loss of luster, powdering, cracking, wrinkling, foaming, brittleness, strength reduction, oxidation, etc. Its test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations.

IIFunctional Area Introduction:

1Radiation system (simulated sunlight):

llight source8The rated power is40WImported ultraviolet fluorescent lamps from the United States ATLAShaveUVA-340andUVB-313The light source is available for users to choose and configure.

lSolar Eye System:

Changes in light intensity can affect the rate of material aging, while differences in spectra may simultaneously affect both the rate and type of material aging

Generate impact. Accurate and reproducible test results can only be obtained by controlling irradiance through the solar eye system.

The solar eye system is a precise closed-loop control system that can automatically maintain the set light intensity through a feedback loop. control

The device can continuously monitor the intensity of ultraviolet light and compensate for changes in light intensity caused by lamp aging or any other factors by adjusting the output of the lamp. The reproducibility and repeatability of the test results of the solar eye irradiance control system are better than those of manual irradiance control, and can effectively extend the life of the lamp tube.

The sun eye is installed in the distribution cabinetUVIn the loop, the solar eye monitors the light intensity of one (two) set of lamps and transmits the data to the controller. The controller compares the measured irradiance value with the set value, and then instructs the power system to adjust the lamp output to maintain the set light intensity value.

QUVThe condensation system is essentially the evaporation of water vapor confined within the experimental chamber by the sample of the experimental chamber. During the condensation cycle, water is heated by the heating element in the water tray, and the test chamber is filled with steam100%When the humidity reaches equilibrium, water vapor continuously condenses on the sample and finally flows back into the water tray.
