Description

Technical Field

[0001] The utility model belongs to the field of testing devices, in particular to an anti-corrosion coating testing device. Background Art

[0002] Anti-corrosion coatings are widely used in modern industry, transportation, energy, marine engineering, and other sectors. They are applied to metal surfaces to prevent and mitigate corrosion. Outdoors, anti-corrosion coatings are subject to the combined effects of solar radiation (UV light), temperature, humidity, and oxidation. This combined effect causes the coating to slowly degrade. Over time, the coating can lose its gloss, discolor, chalk, and crack.

[0003] Aging testing is a part of reliability testing. It is a process of simulating the various factors involved in the actual use conditions of the product to cause aging of the product and conducting corresponding conditions to strengthen the experiment.

[0004] Currently, salt spray spraying and UV exposure are mainly used to test anti-corrosion coatings. However, in fact, under natural conditions, materials will continue to undergo a process of corrosion-exposure-drying outdoors. Salt spray aging-UV aging-drying cycle testing can better simulate the real situation. There are many models of salt spray aging testers and UV ray testers on the market. The current anti-corrosion coating testing method has the following disadvantages: the test items are single, and the test results are quite different from the actual situation; the test instrument needs to be manually replaced for the test sample, which is time-consuming and labor-intensive. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-corrosion coating testing device, comprising a housing, a sample chamber, a sample rack, a servo motor and an electronic control component;

[0006] The shell consists of a first cylinder and a second cylinder, and the first cylinder and the second cylinder are evenly divided into a first test chamber, a second test chamber and a third test chamber by a partition. The second cylinder is evenly distributed with three first openings that are connected to the first test chamber, the second test chamber and the third test chamber.

[0007] Furthermore, a UV lamp tube assembly is obliquely provided on the inner wall of the first test chamber for ultraviolet light aging testing, and a ventilation fan with an air heating function is obliquely provided in the second test chamber, which can discharge water vapor in the chamber to create a dry and stable testing environment. A salt spray nozzle and a salt spray device assembly are vertically provided in the third test chamber. The salt spray nozzle is used to spray the salt solution for testing. The salt spray device assembly contains a water pump, a solenoid valve and a liquid tank. The salt spray nozzle and the salt spray device assembly are both prior art and will not be described in detail here. A collection tank is provided at the bottom of the salt spray nozzle and the salt spray device assembly to collect the salt solution and prevent overflow.

[0008] The back of the housing is closed by a circular sealing plate, a servo motor is provided in the center of the back of the housing, an openable and closable closed door is provided on the front of the housing, a set of supporting legs are connected to the bottom of the housing, and an electric control component is provided on the left side of the housing;

[0009] The UV lamp assembly, the ventilation fan and the salt spray device assembly are all electrically connected to the electronic control assembly and are controlled uniformly by it;

[0010] The sample chamber is a single-sided closed cylindrical structure that is rotatably placed within the second cylinder and connected to the rotating shaft of the servo motor. A second opening is provided on the sample chamber, and the sample chamber can be rotated so that the second opening coincides with the first opening. A set of opposing mounting protrusions are provided on the inner side of the sample chamber. When switching to a different test environment, the sample chamber is rotated by the servo motor until the second opening coincides with the first opening of a different test chamber and communicates with the sample chamber.

[0011] Furthermore, the mounting protrusion is semicircular;

[0012] The sample holder is a rectangular flat plate structure with mounting grooves corresponding to the mounting protrusions on its sides. The sample holder is slidably placed in the sample compartment and can be easily taken in and out.

[0013] Furthermore, a push-pull handle is provided at the front end of the sample holder for easy pushing and pulling. The sample holder is provided with a rectangular opening, and a group of threaded holes are relatively provided on two sides of the rectangular opening. The outer end of the threaded hole is rotatably connected to a handwheel, and a screw is screwed to the threaded hole, and the screw is screwed to the handwheel. A group of clip guide rails are relatively provided on the other two sides of the rectangular opening, and a clip is slidably provided on the clip guide rail. The bottom surface of the clip is rotatably connected to the screw. The extension and shortening of the screw is controlled by rotating the handwheel, thereby controlling the spacing of the clips to achieve clamping of the paint sample.

[0014] Furthermore, the clip is provided with a clip groove, which can make the paint sample placed more firmly and avoid slipping.

[0015] The utility model provides an anti-corrosion coating testing device, which has the advantages of: having three independent test chambers at the same time, which can carry out salt spray aging-ultraviolet aging-drying cycle tests, and more accurately simulate the corrosion conditions under natural conditions; it can automatically switch between different test environments, and there is no need for staff to take out the coating samples and manually put them into different test instruments, which saves a lot of manpower and shortens the test time.
