Technical Field
[0001] This utility model relates to the technical field of coating testing equipment, and in particular to an ultraviolet accelerated weathering tester for powder coating testing. Background Technology
[0002] Powder coating is a solvent-free, 100% solid powder coating. It features solvent-free, pollution-free, recyclable, environmentally friendly, energy and resource saving, reduced labor intensity, and high mechanical strength of the coating film. The ultraviolet weathering tester uses fluorescent ultraviolet lamps as the light source to conduct accelerated weathering tests on materials by simulating ultraviolet radiation and condensation in natural sunlight to obtain the results of the material's weather resistance. After the powder coating is applied, it needs to undergo an aging resistance test in an ultraviolet accelerated weathering tester.
[0003] In existing technologies, such as the ultraviolet accelerated weathering tester disclosed in patent publication number CN214251955U, a machine body is included. The machine body includes a test chamber and a filter chamber. The test chamber is installed above the filter chamber. The filter chamber is equipped with a dust removal chamber I and a dust removal chamber II. Dust-laden air is introduced into dust removal chamber I by an exhaust fan, and large dust particles are intercepted by a screen. Air with a small amount of dust is introduced into dust removal chamber II. Water spray nozzles spray the test samples. While conducting the water spray test, it also serves the function of dust removal. Clean air is discharged to the outside through an exhaust duct. Wastewater after dust collection is guided to the filter assembly for filtration and flows into the water tank, achieving the purpose of fundamental dust removal. Dust removal chamber I and dust removal chamber II work together to improve dust removal efficiency, reduce dust left inside, prevent dust from entering the machine's critical parts and damaging the machine structure, and also allow the test water to flow back to the water tank after the test, realizing water recycling and saving water resources.
[0004] When powder coatings are subjected to aging resistance tests after painting, they are subjected to ultraviolet irradiation and condensation using an ultraviolet accelerated weathering tester to achieve anti-aging purposes. During the condensation process, the internal structure of the tester is cooled by a refrigeration mechanism, causing the powder coating to react upon cooling. Furthermore, the internal structure of the tester needs to be sprayed to carry out the anti-aging reaction. Therefore, how to achieve cooling during the spraying process to reduce test costs is an urgent problem to be solved. Utility Model Content
