The full name of the salt spray test machine is a salt spray test machine, which is mainly used to test the corrosion resistance of samples. At present, it is widely used in aerospace industry, automotive electronics, electronic electrician, mobile phone digital, plastic products, metal materials and other industries to test its corrosion resistance. It is also to simulate extreme conditions under natural conditions or working conditions to understand the properties of each sample. performance temperature.

The working principle of the salt spray testing machine is relatively simple. It mainly uses corrosive gas and liquid to spray the sample. By spraying the corrosive gas and liquid until the corrosion of the sample occurs, the longer the time is as the corrosion resistance of the sample, the It means that the corrosion resistance of the sample is better.

The working principle of the salt spray test is to compress the corrosive solution into an air spray, and then wrap the spray on all sides of the sample as much as possible. This test can be carried out continuously or cyclically until the expected corrosion phenomenon appears on the sample. The corrosion time is then recorded to indicate the corrosion resistance of the sample.

Generally, the corrosion solution in the salt spray testing machine is mainly 5% sodium chloride solution or adding 0.26 grams of copper chloride per liter to the sodium chloride solution as a salt spray corrosion solution. In addition, the salt spray testing machine can independently adjust the settlement and spraying volume of salt spray to ensure constant test temperature, convenient operation and stable test environment. Therefore, it is often used to test the corrosion resistance of daily necessities or industrial products.
