Salt spray cyclic corrosion test chamber, titanium plate material, dry wet high and low temperature function

The salt spray test chamber can detect various performance aspects of automotive components, accurately reproduce the atmospheric salt spray corrosion environment, and is widely used in automotive inspection work. At present, the salt spray test mainly adopts cyclic corrosion salt spray test, which can alternately change different corrosion environments to improve the accuracy of detection. In the process of salt spray corrosion, the testing method should be selected in combination with automotive parts to achieve twice the result with half the effort. It is also important to introduce advanced testing equipment to make the testing results more authentic and effective.

heating system

Mixing chamber: titanium alloy heater is used, and the circulating fan is used for strong air supply and circulation. P.I.D controls the heating amount to achieve temperature balance. Laboratory: titanium alloy heating pipe is used, and air is directly heated. P.I.D controls the heating amount to achieve temperature balance. Pressure bucket: titanium alloy heating pipe is used, and water is heated. Compressed air enters the hot water and overflows in the form of bubbles. P.I.D controls the heating amount to achieve constant temperature and pure spray gas.
