Problems solved by technology
[0004] In order to solve the above-mentioned technical problem, the present invention provides a kind of salt spray corrosion test device for material metal experiment, to solve the existing similar material metal test salt spray corrosion test device when in use, the metal material of required experiment is rotated The adjustment effect is poor. The metal material is usually in a static state and corrodes with the salt spray contained in the air. It is difficult for the bottom end surface of the metal material to contact with the salt spray contained in the air, which easily affects the salt spray corrosion test of the bottom end surface of the metal material. problem of effect

The invention provides a salt-spray corrosion experimental device for material metal experiments. The device comprises an atomizing nozzle and a sealing cover; the inside of a main body is hollow; a salt solution storage bucket is installed inside the main body; a liquid filling port is arranged at the left side end surface of the main body; a water pump is installed inside the main body; and thewater incoming end of the water pump is communicated with the inside of the salt solution storage tank through a pipeline. A metal material can be conveniently arranged in a metal block fixing opening; a fixing sheet is pushed through a threaded rod so as to move into the metal block fixing opening; the metal material is fixed inside a rotating shaft, so that fixing operation on the metal materialis realized, and therefore, a salt-spray corrosion experiment in a later stage can be facilitated; the atomizing nozzle and the water pump are adopted, a salt solution can be atomized and sprayed into a glass test box, so that salt spray is adhered to the metal material, and therefore, the corrosiveness of an external salt spray environment to the metal material can be simulated, and metal corrosion results more in line with real conditions can be obtained.
Description
technical field [0001] The invention belongs to the technical field of material metals, and more specifically relates to a salt spray corrosion test device for material metal experiments. Background technique [0002] The metal corrosion experiment is used to test the corrosion resistance of the metal and measure the service life of the metal. The salt spray corrosion test device is to simulate the corrosion of the metal in the natural environment. Because the corrosion time of metal in the atmospheric environment under natural conditions is relatively long, and in order to obtain the results of metal corrosion resistance and service life relatively quickly, it is necessary to conduct tests in the salt spray corrosion experimental device, which requires salt spray corrosion. The devices in the experimental device are closer to the environmental conditions of nature. [0003] Based on the above, when the existing salt spray corrosion test device for similar material metal ex...
