Description

Technical Field

[0001] This utility model relates to the field of corrosion testing technology, specifically to a corrosion testing machine. Background Technology

[0002] Many items corrode during use, and corrosion refers to the process by which an item is worn away and damaged by the surrounding medium. For example, cookware is a common and frequently used cooking utensil in daily life. During the design and finalization testing of cookware, it is necessary to use boiled acidic liquid, neutral liquid, alkaline liquid or their vapor to test the corrosion resistance of the anti-corrosion coating on the cookware material. The existing anti-corrosion testing machine consists of a machine body, a heating platform, a test cup and a cooling unit. The heating platform is located on the machine body. After the test solution is prepared and the sample is placed, the test cup is placed directly on the heating platform for heating to start the corrosion resistance test.

[0003] The existing corrosion resistance testing machine has the following disadvantages in actual use: 1. It lacks a fixing device to secure the test cup, making it prone to tipping over due to accidental collisions, resulting in poor stability and safety; 2. It lacks heat insulation protection measures, requiring the use of heat-resistant gloves to remove the test cup from the heating platform, which is inconvenient after heating and testing, and can easily cause burns during misoperation; 3. The heating platform is located at the bottom of the test cup, resulting in uneven heating of the test solvent and prolonged heating time.
