The invention discloses a
salt spray test device for simulating a salt spray environment, and relates to the technical field of
material analysis equipment. The device comprises a main box body, a box cover, an ultrasonic salt mist generating device, an axial flow fan, an
airflow distributor, an
airflow guide device, a salt mist metering device, a control
device panel and the like, wherein the main box body is provided with an inner cavity and a top sealing water tank; an auxiliary box body is arranged on one side of the main box body, and the auxiliary box body is provided with an inner cavity and is communicated with the inner cavity of the main box body; the upper end of the auxiliary box body is provided with a sunken
saline water tank for storing
saline water; the bottom of the ultrasonic salt mist generating device is communicated with the
salt water tank through a conduit. Through the innovative structure, many problems of a traditional test are solved, salt mist distribution is optimized, and uniformity is ensured; temperature and
humidity are accurately controlled, and
simulation is more real; an
ultraviolet light source is introduced, the illumination period is precisely regulated and controlled, and the device fits the
natural environment; the
corrosion resistance of the material can be comprehensively and accurately evaluated, reliable test support is provided for research, development and application of the material, and product quality and reliability are improved.
