Working principle of salt spray test chamber

The purpose of the salt spray test chamber is that the salt spray test is a test that artificially simulates the salt spray environment. Compared with exposure tests under atmospheric conditions, it has significant advantages: the corrosive environment can be controlled, and the environmental reproducibility is good; The experimental time has been significantly shortened; It has saved a lot of manpower, financial resources, and material resources. Structural characteristics of salt spray test chamber The equipment is mainly composed of box, spray system, heating system and control system.

Appearance of the box: The appearance design of this salt spray corrosion test box is beautiful, the structure is reasonable, and the lines are smooth and natural. The outer shell of the box is made of imported PVC plastic sheet, which is smooth, bright, scratch free, corrosion-resistant, easy to clean, and leak free. The inner liner is made of the same PVC plastic sheet, with a maximum temperature resistance of 60 degrees. Various auxiliary accessories are corrosion-resistant and have a reasonable structural design. Spray system: tower spray system, equipped with salt liquid filtration system, without crystallization nozzle, with uniform distribution of salt spray and free adjustment of sedimentation.

Intelligent high-precision digital display microcomputer controller, temperature control adopts P I D+S S R. Coordinated control of the same channel in the system can improve the stability and lifespan of control components and interface usage; Thin film button, touch setting, digital and direct display, temperature control output power is calculated by microcomputer to achieve high precision and efficiency in electricity consumption;.
