The salt spray corrosion test chamber is a commonly used test chamber product that uses salt spray corrosion to test the corrosion resistance of the tested samples. It is suitable for salt spray corrosion testing of materials such as components, electronic components, and metal materials. Today, the editor will mainly introduce the testing principle and structural characteristics of the salt spray corrosion test chamber, hoping to help everyone.
Testing principle of salt spray corrosion test chamber
The corrosive solution is sprayed into mist by compressed air, which surrounds the test sample in the testing chamber.
Testing can be continuous or cyclic.
The corrosion resistance of each sample is defined as the time during which corrosion occurs, and the longer the time, the better the corrosion resistance.
Technical data of salt spray corrosion test chamber
Structural characteristics of salt spray corrosion test chamber
1. Both the inner and outer bile ducts are molded with epoxy fiberglass, which has the characteristics of light weight, corrosion resistance, high strength, no leakage, smooth surface, and easy cleaning.
2. The water sealed form prevents salt spray from overflowing, and the jacket air duct heats up quickly and evenly in the working room.
3. The top cover of the salt spray box is designed with a top angle of 110-112 ℃ to prevent condensed water inside the box from directly dripping onto the test sample.
4. The spray mode is tower spray, and the spray tower is placed in the middle of the bottom of the studio. The material of the nozzle is fired from quartz glass, and the sprayed mist is fine, with salt spray naturally settling and evenly distributed.
5. The control system of the equipment is placed on the top right of the box, which is convenient for users to operate. The panel is equipped with a power switch, a fog exhaust switch, a spray transfer switch, two PID self-tuning digital display instruments, a device running time timer and a gap spray timer. An overtemperature protector is also provided on the circuit board of the box.
