The equipment of the salt spray corrosion test chamber is composed of chamber, chamber heating, humidification system, saturation system, electrical control system, air supply system, protection system and so on. The outer box is mainly composed of a salt spray box (spray chamber), a salt solution storage tank, a salt solution level controller, a properly processed compressed air system, one or more atomizing nozzle central spray towers, an adjustable baffle , Model bracket (satisfying the angle with the vertical line is (20 ± 5 ° support plate), air saturator, box immersion heating equipment and necessary temperature and humidity control equipment, etc. When the salt solution is led out of the solution storage tank and flows through the liquid level controller into the bottom of the spray tower, under the action of a certain pressure of air flow (pressure difference), the free-suction nozzle sucks people and atomizes to form a dense salt mist. The baffle plate in the upper part of the tower guides and evenly settles on the test sample plate in the spray chamber. The structure of the instrument should ensure that the drip accumulated on the top or the lid will not drip on the test panel. The drops on the test sample plate will not drop into the solution storage tank and be re-atomized. In addition to the neutral salt spray test, for the acetic acid-salt spray test and the copper-accelerated acetic acid-salt spray test (CASS test), the equipment only needs to add acetic acid or copper chloride and acetic acid to the salt solution according to the standard The test conditions can be carried out in an ordinary salt spray test box. The circulating salt spray test chamber is designed to meet the wet (salt spray) / dry / humidity-cyclic corrosion environment test. In addition to all the components of the ordinary salt spray test box, the equipment also needs to increase the temperature control of dry hot air blower and dry air (provide a relative humidity of 20% to 30% and a relative humidity of (50 ± 20)% Deoiling and dedusting air) feeder, and a programmable program controller. In order to set up and complete the circulation procedures such as spraying salt spray, sending dry hot air, sending near-saturated humid air or semi-saturated humid air respectively in the test box.
