Successful case of composite salt spray test chamber
At present, the test equipment commonly used at home and abroad is the compound salt spray test chamber. The equipment is mainly composed of a composite salt spray test chamber (spray chamber), a salt solution storage tank, a salt solution level controller, a properly treated compressed air system, one or more atomizing nozzles, a central spray tower, and an adjustable baffle. , Sample bracket (satisfying the angle between the vertical line is (20±5° support plate), air saturator, box immersion heating equipment and necessary temperature and humidity control equipment. When the salt solution comes from the solution storage tank When the internal outflow flows through the liquid level controller and enters the bottom of the spray tower, under the action of a certain pressure of airflow (pressure difference), the free suction nozzle sucks people and atomizes to form a dense salt mist, composite salt spray test chamber which is guided by the baffle on the upper part of the spray tower After spraying, it will evenly settle on the test sample plate in the spray chamber.
The structure of the instrument should ensure that the drops accumulated on the roof or the box cover will not drip on the test sample plate.
The drops on the test sample plate will not drip. Re-atomize in the solution tank. In addition to the neutral salt spray test, the equipment can also complete the acetic acid-salt spray test and the copper-accelerated acetic acid-salt spray test (CASS test) as long as the salt solution is added with acetic acid or Copper chloride and acetic acid can be carried out in an ordinary composite salt spray test chamber by changing the corresponding test conditions.
