Description

Technical Field

[0001] The utility model relates to the technical field of salt spray corrosion test, in particular to a salt solution automatic proportioning test device for salt spray corrosion test. Background Art

[0002] Neutral salt spray test (NSS) is to spray salt water containing (5±0.5)% sodium chloride and pH value of 6.5-7.2 through a spray device in a specific test chamber, let the salt spray settle on the test piece to be tested, and observe its surface corrosion state after a certain period of time. Neutral salt spray test is suitable for determining the quality and uniformity of protective coatings and for comparing the ability of samples with similar structures to resist salt spray corrosion. Traditional salt solution ratio is mostly artificially added to the solution barrel with a corresponding proportion of pure water and analytical pure sodium chloride, stirred evenly with a stirring paddle, and then the solution pH is measured. After meeting the requirements, it is divided into small buckets and filled into the salt spray chamber salt water barrel. Salt spray test is an environmental test that mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials. It is divided into two categories, one is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a test equipment with a certain volume space - the salt spray test chamber, which uses artificial methods to create a salt spray environment in its volume space to assess the salt spray corrosion resistance quality of the product.

[0003] Although the existing salt spray test can assess the salt spray corrosion resistance of the product, the following problems may occur during actual use: 1. The traditional salt solution proportioning operation method is complicated, labor-intensive, physically demanding and time-consuming, and has certain errors. Each person has subjective errors in judging the uniformity of stirring and the amount of water added. When proportioning the solution, it is inevitable that the solution will spill onto the ground, which is not conducive to the 5S control of the laboratory. Therefore, an automatic salt solution proportioning test device for salt spray corrosion test is needed to solve the above problems. Utility Model Content
