Description

Technical Field

[0001] This application relates to the technical field of salt spray test equipment, and particularly relates to a salt spray test chamber. Background Art

[0002] Salt spray test is an accelerated corrosion test method that simulates the conditions of the ocean or a saline environment, and is used to evaluate the corrosion resistance of the surface of materials or products. By spraying a certain concentration of sodium chloride solution in a salt spray test chamber, it simulates harsh environmental conditions such as high salinity, humidity, and temperature, so as to quickly observe the corrosion situation of the sample under test under these conditions, and to detect the reliability of the sample under test.

[0003] Generally, a salt spray test chamber is used to conduct salt spray tests on samples. The salt spray test chamber includes a box body, a box cover, a containing box, a control console, a spray tower, an exhaust pipe, a drain pipe, and a water seal trough body. The box cover is hinged to the box body, and the sample is placed inside the box body. The spray tower is connected inside the box body, the containing box is communicated with the spray tower, a solution is loaded into the containing box, the spray tower can spray the solution into the box body to form salt spray inside the box body, and the control console controls the spray time and spray volume of the spray tower. The water seal trough body is connected to the top side of the box body. When the box cover closes the top side of the box body, the edge of the box cover is located inside the water seal trough body. Water is added to the water seal trough body so that the water submerges the edge of the box cover, which can prevent the salt spray inside the box body from leaking to the outside. Both the exhaust pipe and the drain pipe are communicated with the box body. After the salt spray test is completed, the exhaust pipe can discharge the gas inside the box body, and the drain pipe can discharge the waste liquid inside the box body.

[0004] During the operation of the salt spray test chamber, the salt spray will fill the entire box body, and the salt spray will enter the water seal trough body from between the box cover and the box body. When the salt spray comes into contact with the water in the water seal trough body, the salt will gradually dissolve and accumulate, forming salt residues on the inner wall of the water seal trough body. And after water is injected into the water seal trough body, in order to prevent the water in the water seal trough body from overflowing, there is a certain distance between the water in the water seal trough body and the top side of the water seal trough body, and the salt will remain on the side wall of the water seal trough body that is not submerged by water. After the salt spray test is completed, generally the water in the water seal trough body will be drained, and the remaining water in the water seal trough body will gradually evaporate, leaving salt residues on the inner wall of the water seal trough body, making it difficult to remove the remaining salt in the water seal trough body.

[0005] After the salt spray test is completed, the box cover will be closed to seal the box body, and it is difficult for the moisture in the outside air to enter the box body. Therefore, the box body generally will not be corroded by salt. However, the water seal trough body is exposed to the air, and the remaining salt absorbs the moisture in the air, which will cause corrosion of the water seal trough body, resulting in damage to the water seal trough body, thereby affecting the water seal effect.

The containing chamber 12 communicates with the spray tower 3. The inside of the containing chamber 12 is used for storing a solution. The solution enters the spray tower 3, enabling the spray tower 3 to spray salt spray inside the chamber body 11. The filling pipe orifice 13 is fixedly connected to the chamber body 11 and communicates with the spray tower 3. The filling pipe orifice 13 facilitates manual filling of the solution.

For this application, since the salt spray test generally lasts for a long time, the inlet pipe 6 and the outlet pipe 7 are not opened simultaneously during the salt spray test, thereby reducing the waste of water resources. After the salt spray test is completed, open the inlet pipe 6 and the outlet pipe 7 simultaneously, so that a water flow is formed in the water seal tank body 5, which can dissolve and carry away most of the remaining salts.

[0039] The implementation principle of Embodiment 1 of this application for a salt spray test chamber is as follows: Place the sample on the support frame 17. The water inlet pipe 6 injects water into the water seal tank body 5, and the water submerges the edge of the tank cover 2. The spray tower 3 sprays salt spray inside the tank body 11, thereby conducting a salt spray test on the sample.
