Technical Field

[0001] This utility model relates to the field of corrosiveness testing of acidic degreasing agents, and in particular to a device for testing the corrosiveness of acidic degreasing agents. Background Technology

[0002] In industrial production and laboratory testing, acidic degreasers are widely used in metal surface treatment, rust removal, and degreasing processes. However, acidic degreasers are usually highly corrosive, and their performance stability, concentration variation, and corrosion effect need to be rigorously tested and evaluated to ensure their safety and effectiveness in practical applications.

[0003] Existing corrosive tests for acidic degreasers typically require the experimenter to place the test cup under a dripping device to allow the acidic degreaser to drip into the test cup, and then place the metal part to be tested into the test cup, immersing it in the acidic degreaser for testing. However, when conducting comparative tests, the experimenter needs to manually collect the liquid using the test cup, which is cumbersome and inefficient.

[0004] Therefore, it is necessary to design an acid degreasing agent corrosion testing device that can quickly and automatically switch test cups, facilitate the addition of acid degreasing agents to the test cups, and is easy to use. Utility Model Content

[0022] When using this device, first place the base 1 in the acidic degreasing agent corrosive testing area, then place the test cup 6 on the heating plate 5. Next, connect the acidic degreasing agent delivery pipe to the external delivery sleeve 15. The processor starts the servo motor 2 through the control module, driving the gear to rotate.
