Detailed implementation manners
[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1 - 3 , the present invention provides the following technical solutions: A corrosion resistance test device for polyetherimide materials, including a reaction tank 10. A fixed block 11 is fixedly installed on the top of the reaction tank 10. A water storage tank 2 is fixedly installed on the top of the fixed block 11. An inlet is fixedly installed on the top of the water storage tank 2. A movable cover 1 is threadedly installed on the top of the inlet. A conveying pipe 4 is fixedly installed at one end of the water storage tank 2. A conveying pipe valve 3 and a spraying head 12 are fixedly installed on the surface of 4. And there are two spraying heads 12, and the spraying heads 12 are linearly arranged on the surface of the conveying pipe. A driving motor 17 is fixedly installed on the back of the reaction tank 10. The driving motor 17 is fixedly installed with a stirring shaft 13 through the rotating shaft at the output end. Stirring blades 16 are fixedly installed on the surface of the stirring shaft 13. And the stirring blades 16 are fixedly installed directly below the spraying heads 12. A placing rod 14 is fixedly installed in the middle of the reaction tank 10. And there are multiple placing rods 14, and the placing rods 14 are linearly arranged inside the reaction tank 10. A collection box 15 is fixedly installed below the placing rod 14. A water tank 24 is fixedly installed at the bottom inside the reaction tank 10.
[0021] First, place the polyetherimide material to be tested above the placement rod 14. Then, open the valve 3 of the delivery pipe, and deliver the brine inside the water storage tank 2 to the spray head 12 through the delivery pipe 4. Finally, spray the salt solution into the interior of the reaction tank 10 through the spray head 12. Drive the stirring shaft 13 and the stirring blades 16 to rotate through the drive motor 17. Since the stirring blades 16 are located below the spray head 12, the rotating stirring blades 16 can spread the salt solution sprayed by the spray head 12 farther, making the device spray the salt solution more evenly and the test results more accurate. For the setting of the water tank 24, it ensures the humidity and temperature inside the reaction tank 10 to meet the reaction conditions during material testing. When it is necessary to drain the salt solution inside the collection tank 15, the drain pipe valve 18 can be opened, so that the salt solution inside the collection tank 15 can flow out through the drain pipe 19. Since the electric heater 21 and the heating plate 20 are fixedly installed at the bottom of the reaction tank, the heating plate 20 can be heated through the electric heater 21, so that the temperature of the distilled water inside the water tank 24 can rise to meet certain chemical reactions that need to be carried out in a high-temperature environment. For the setting of the control box 7, it enables the device to automatically control the switches of the spray head 12 and the drive motor 17, and can also detect the temperature and humidity inside the reaction tank 10, increasing the convenience and automation of the device. Since the support legs 23 are fixedly installed around the bottoms of the reaction tank 10 and the control box 7, and the anti-slip pads 22 are fixedly installed at the bottoms of the support legs 23, the friction between the bottoms of the support legs 23 and the ground can be increased, enabling the device to be stably placed on the ground horizontally on a smooth ground. For the setting of the control box 7, it enables the device to automatically control the switches of the spray head 12 and the drive motor 17, and can also detect the temperature and humidity inside the reaction tank 10, increasing the convenience and automation of the device. Since the support legs 23 are fixedly installed around the bottoms of the reaction tank 10 and the control box 7, and the anti-slip pads 22 are fixedly installed at the bottoms of the support legs 23, the friction between the bottoms of the support legs 23 and the ground can be increased, enabling the device to be stably placed on the ground horizontally on a smooth ground. All the electrical equipment in this device is powered by an external power supply.
[0022] In one aspect of this embodiment, when it is necessary to drain the salt solution inside the collection tank 15, the drain pipe valve 18 can be opened, so that the salt solution inside the collection tank 15 can flow out through the drain pipe 19. Since the electric heater 21 and the heating plate 20 are fixedly installed at the bottom of the reaction tank, the heating plate 20 can be heated through the electric heater 21, so that the temperature of the distilled water inside the water tank 24 can rise to meet certain chemical reactions that need to be carried out in a high-temperature environment.
[0023] In one aspect of this embodiment, the control box 7 is arranged such that the device can automatically control the switches of the spray head 12 and the drive motor 17, and can also detect the temperature and humidity inside the reaction tank 10, which increases the convenience and automation of the device. Since support legs 23 are fixedly installed around the bottoms of the reaction tank 10 and the control box 7, and anti-slip pads 22 are fixedly installed at the bottoms of the support legs 23, the friction between the bottoms of the support legs 23 and the ground can be increased, enabling the device to be stably placed on the ground horizontally on a smooth surface.
[0024] In one aspect of this embodiment, since a movable door 8 is movably installed on the front of the reaction tank 10, and a handle 6 is fixedly installed on the surface of the movable door 8, the movable door can be opened or closed by pulling the handle 6. Since a glass window 9 is provided on the surface of the movable door 8, it is more convenient to observe the corrosion resistance of the materials inside the reaction tank 10, enabling better observation of the reaction condition of the materials to avoid overreaction or insufficient reaction.
[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
