The main purpose of the product of the UV aging test box: It is suitable for the characteristic reliability test of a variety of industrial products. The machine and equipment selected use the fluorescent UV germicidal lamp as the light source. According to the simulation of natural light, the UV spectrum of the raw material Carry out aging test of ultraviolet radiation source. Since it is a simulation to simulate the ultraviolet radiation of sunlight, in the experimental operation process, the actual operation staff of the experiment should try to avoid contact with ultraviolet rays. This product series is suitable for the aging test of non-metallic materials for sunlight resistance and artificial sources.

The UV aging test box simulates the influence of precipitation and dew

The time for outdoor raw materials to touch the moisture in the body can be as long as 12 hours a day. Scientific research has concluded that the key cause of such outdoor dampness and coldness is dew, not precipitation. The UV accelerated weather resistance tester simulates the influence of moisture in the body outside the room based on a series of unique basic principles. In the cold cycle system circle of machinery and equipment, there is a water storage tank at the bottom end of the shell, which is heated to generate water vapor. The hot steam keeps the air humidity in the test chamber at 100% and maintains a relatively high temperature. The design concept of the product ensures that the test sample actually constitutes the outer wall of the test box, and the reverse side of the sample is exposed to the indoor air. The cooling effect of indoor air quality causes the sample ambient temperature to drop to a level less than the steam temperature. The appearance of this temperature difference causes the sample to be converted into liquid from beginning to end during the whole process of the entire cold cycle system. This kind of cold substance is very stable pure pure water. This kind of mineral water improves the reproducibility of the experiment, and in addition prevents the water mark problem.

Because the outdoor exposure to the wet and cold time is as long as 12 hours a day, the wet and cold cycle time of the UV accelerated UV aging test box is generally for several hours. It is suggested that each cold doubt cycle should last at least 4 hours. Note that the anti-ultraviolet exposure and cold exposure in the machinery and equipment are carried out separately, which is consistent with the specific climatic conditions.

In terms of the whole process of some applications, water sprinkling can more effectively simulate the natural environment standards of the final application. Water spouting is extremely effective in simulating the corrosion of mechanical equipment caused by the drastic temperature change and the erosion of precipitation. Flat roofs, automotive materials, and architectural coatings used in metal material engineering buildings or structures often suffer sudden temperature changes. For example, in the hot summer, when the heat is deposited, it suddenly subsides due to heavy rain. The adverse effects of such drastic temperature changes are a challenge for many raw materials. The UV accelerated weathering tester is designed and conceived to reproduce such standards.

Because it is often scoured from precipitation, the architectural coating layer of wood, including paint and additives, will appear relatively corrosive. Recent scientific studies have shown that this type of precipitation scouring posture can wash away the anti-dissolving architectural coating layer on the surface of the raw material, and the ultraviolet aging test box then immediately exposes the raw material itself to the destructive effects of ultraviolet rays and moisture. This whole process can be repeated several times, resulting in a decline of raw materials, which cannot be reproduced only by cautious methods.
