[0002] In the coastal environment, building coatings will face special environmental conditions, such as high humidity, salt spray, strong wind and changing temperature, etc. These factors may accelerate the aging process of the coatings and reduce their protective performance. Therefore, through systematic durability testing to evaluate the performance of coatings in the coastal environment, not only can the coating formula be optimized to improve its protection effect, but also scientific basis can be provided for the long-term use and maintenance of buildings.

[0003] When testing the durability of coastal building coatings, it is usually necessary to use a salt spray test machine to simulate the marine climate of the coastal environment, which is used to evaluate the corrosion resistance of materials and products in the salt spray environment. The salt spray equipment generates salt spray by heating sodium chloride solution to simulate the corrosion conditions in the actual use environment, so as to accelerate the corrosion process of the materials and evaluate their corrosion resistance in a short time. During the test, the salt spray test machine will generate waste gas containing acidic components, such as hydrochloric acid. These acidic components have potential hazards to the environment and human health. Therefore, a device for simulating the construction changes of coastal environment of durable coatings is proposed.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 , a device for simulating the changes in the construction of a building with a durable coating in a coastal environment in this embodiment, includes a control box 1 and a test box 2. The control box 1 is arranged on one side of the test box 2. An atomization assembly is arranged inside the test box 2. A box cover 7 is hinged on the top of the test box 2. A purification assembly is arranged on the side wall of the test box 2.

[0022] Among them, the box cover 7 is made of a transparent material, so as to facilitate observing the changes of the specimens in the test box 2. The side surface of the box cover 7 is a trapezoidal structure.

[0023] The purification assembly includes a purification box 9. The purification box 9 is fixed on the side wall of the test box 2. An air pump 10 is fixed on the top of the purification box 9. An air outlet pipe 11 is fixedly connected to the air pump 10. The air outlet pipe 11 penetrates through the purification box 9 and extends to the inner lower part. A gas collection box 13 is fixedly penetrated through the top of the box cover 7. An air extraction hose 12 is fixedly connected between the gas collection box 13 and the air pump 10. A plurality of air inlet holes 131 are opened at the bottom of the gas collection box 13. A drain pipe is fixedly penetrated through one side of the purification box 9. A first valve is installed on the drain pipe. An exhaust pipe is fixedly penetrated through the top of the purification box 9.

[0024] Please refer to Figure 1 , Figure 2 , in this embodiment, a sealing member for blocking the air inlet holes 131 is arranged on the inner top wall of the box cover 7. The sealing member includes two sealing plates 14. A moving block 18 is fixedly connected to the top of the sealing plate 14. A threaded rod 17 is threadedly connected inside the moving block 18. The threaded rod 17 is rotatably connected in an installation groove 16 opened on the inner wall of the control box 1. A servo motor 15 is fixed on the inner wall of the installation groove 16. The output shaft of the servo motor 15 is fixedly connected to one end of the threaded rod 17. The moving block 18 is slidably connected inside the installation groove 16. Both sealing plates 14 are attached to the bottom of the gas collection box 13.

[0025] By setting up a purification mechanism, after placing the test block on the object placing rod 19 and closing the box cover 7 for a salt spray test, before opening the box cover 7, the control box 1 controls the servo motor 15 to drive the threaded rod 17 to rotate, so that the moving block 18 drives the sealing plate 14 to translate, exposing the air inlet hole 131 at the bottom of the air collecting box 13. Then, the air pump 10 sucks the waste gas containing acidic components generated inside the box cover 7 into the purification box 9, neutralizing the acidic waste gas with the alkaline solution in the purification box 9, thus achieving a purification effect.

[0026] It should be noted that the air inlet hole 131 on the air collecting box 13 can be blocked by two abutting sealing plates 14, thereby preventing salt mist from entering the interior of the air collecting box 13 during the test.

[0027] In this embodiment, the atomization assembly includes a solution tank 3, the solution tank 3 is installed on the inner bottom wall of the test chamber 2, an electric heating rod 4 is arranged inside the solution tank 3, a spray tower 5 is fixedly penetrated through the top of the solution tank 3, a fog volume regulator 6 is arranged at one end of the spray tower 5 away from the solution tank 3, a liquid inlet pipe 8 is fixedly penetrated through one side of the solution tank 3, one end of the liquid inlet pipe 8 away from the solution tank 3 penetrates through the test chamber 2 and extends to the outside, and a second valve is arranged on the liquid inlet pipe 8.

[0028] It should be noted that through the setting of the atomization assembly, the salt solution is added into the interior of the solution tank 3 through the liquid inlet pipe 8 and stored. During the test, the salt solution can be heated by the electric heating rod 4 to generate salt mist. The salt mist continuously settles in the test chamber 2 and contacts the surface of the specimen, forming a corrosion environment, so as to simulate the conditions of salt spray corrosion in the marine environment, thereby testing the durability of the coating.

[0029] Among them, a plurality of object placing rods 19 are arranged at equal intervals in the front and rear inside the test chamber 2, and the spray tower 5 is located at the gap between two of the object placing rods 19.

[0030] It should be noted that through the setting of the plurality of object placing rods 19, it is convenient to place the specimen on the object placing rods 19, and the gap between the object placing rods 19 facilitates the full contact of the salt mist with the surface of the specimen.

[0031] The working principle of the above embodiment is as follows: When in use, place the specimen coated with the coating on the storage rod 19, close the box cover 7, heat the salt solution in the solution tank 3 through the electric heating rod 4 to form salt mist, which is ejected from the spray tower 5 through the fog volume regulator 6. The salt mist continuously settles in the test chamber 2 and contacts the surface of the specimen to form a corrosion environment, thus simulating the conditions of salt spray corrosion in the marine environment, and then testing the durability of the coating. After the test, control the box 1 to control the two servo motors 15 to drive the threaded rod 17 to rotate. Under the limiting action that the moving block 18 is slidably connected to the installation groove 16, the two sealing plates 14 can be moved in opposite directions to open. Then, the air pump 10 is used to suck the waste gas containing acidic components generated in the test chamber 2 into the purification box 9 through the air collecting box 13, so that the acidic waste gas is neutralized with the alkaline solution in the purification box 9, thereby achieving the purification effect.
