Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a sensor-based sustained-release anti-corrosion coating permeability detection device. Background Art

[0002] As the requirements for anti-corrosion coatings in the industrial field continue to increase, especially in the petrochemical, marine engineering, automobile manufacturing and other industries, the demand for testing the permeability and long-term anti-corrosion performance of coatings is increasing.

[0003] The patent with publication number CN221993284U relates to a device for detecting the permeability of an anti-corrosion coating under high temperature and high pressure, comprising a detection box, an internal fixed rod of the detection box being connected to a partition, a fixed rod inside the detection box and located at the top of the partition being connected to a collection bin, a connecting pipe having one end penetrating the detection box and extending into the interior thereof being fixedly connected to the top surface of the detection box, a solenoid valve being fixedly installed on the outer peripheral wall of the connecting pipe, an anti-corrosion coating being placed on the top surface of the partition, and a plurality of connecting holes being opened on the bottom surface of the partition, the device for detecting the permeability of an anti-corrosion coating under high temperature and high pressure, which conveniently transfers external high-pressure gas through the action of the connecting pipe. It is transported into the interior of the test box, and then the permeability of the anti-corrosion coating is tested under the action of the first pressure test gauge and the second pressure test gauge, which is convenient for the staff to operate.

At the same time, the air pump 3 can be started, and the steam generated by the heating pool 4 is extracted and enters the bottom of the heating pool 4 through the vent pipe 2. In this way, the test board 8 coated with the anti-corrosion coating can be tested for water vapor, thereby simulating the temperature changes and humidity environment encountered by the coating in actual use, helping to evaluate the permeability of the coating under high temperature and humid conditions. At this time, the visual observer 6 can be used to observe whether there are water droplets on the bottom of the test board 8, so that the visual observer can provide feedback to the inspector.

When placing the test board 8 into the interior of the shell 1, first open the sealed door at the rear of the shell 1 with the handle. At this time, the test board 8 is gradually pushed into the top of the hollow table 5. During the pushing process, the test board 8 will contact the curved surface at the bottom of the curved splint 15, so that the curved splint 15 moves upward through the extrusion force, and the upward movement of the curved splint 15 drives the elastic rod 14 to move upward.

At this time, the water will be heated to generate steam. At the same time, the air pump 3 can be started, and the steam generated by the heating pool 4 will be extracted and enter the bottom of the heating pool 4 through the vent pipe 2, so that the test board 8 coated with the anti-corrosion coating can be tested for water vapor. During the testing process, the motor starts and drives the threaded rod 7 to rotate. The threaded rod 7 rotates through the reciprocating thread groove on the surface to drive the T-shaped plate 9 to move backward. The rotating shaft 11 moves upward to drive the test rod 10 to move upward, so that the test board 8 can be further tested and the integrity of the coating can be quickly identified. When the test board 8 is placed in the interior of the shell 1, the sealed door at the rear of the shell 1 is first opened by the handle.

[0019] Working principle: After the water vapor detection is completed, the T-shaped plate 9 moves backward and contacts the Y-shaped frame 164, and pushes the Y-shaped frame 164 to rotate. The rotation of the Y-shaped frame 164 drives the rotating rod 162 to rotate, thereby increasing the irradiation range of the ultraviolet light of the ultraviolet lamp 163, thereby simulating the scene of the anti-corrosion coating being exposed to sunlight in an actual environment. After the T-shaped plate 9 passes over the Y-shaped frame 164, the Y-shaped frame 164 rotates in the opposite direction due to gravity, so as to further increase the irradiation range.
