The salt spray test chamber is mainly used for hardware electroplating, hardware, electronic parts, chemical coatings, baking varnishes, automobiles, motorcycles, hardware sanitary ware, screws, springs, magnetic materials, organic and inorganic coatings, anode treatment, anti-rust oil Quality inspection in other industries, testing the corrosion resistance of its products, and assessing the salt spray corrosion resistance of materials and their protective layers.

The salt spray test chamber is a necessary test equipment in the fields of aviation, automobiles, home appliances, scientific research and other fields. It is used to test and determine the temperature of electrical, electronic and other products and materials for high temperature, low temperature, alternating humidity and heat or constant test The parameters and performance after the environment changes, or the parameters and performance after the temperature environment changes in the constant damp heat test. It is mainly suitable for schools, factories, military industries, research positions, and other units.

There are four types of tests that the salt spray test chamber can do: neutral salt spray test (NSS), copper accelerated acetic acid salt spray test (CASS), alternating salt spray test, and acetic acid salt spray test (ASS test). Of course, different tests not only require different solutions, but also the design and structure of the cabinet. The temperature of the neutral salt spray test (NSS) test chamber is required to be (35±2)℃, the humidity is greater than 95%, and the amount of mist reduction is 1～2mL/80cm*h. The nozzle pressure is 78.5～137.3kPa (0.8～1.4kgf/ cm2). In the salt spray test box, the salt water containing (5±0.5)% sodium chloride and the pH value of 6.5 to 7.2 is sprayed through the spray device, and the salt spray is allowed to settle on the test piece to be tested. After a certain period of time Observe the corrosion state of the surface.
