Salt spray corrosion test chamber experimental principle

The salt spray corrosion test chamber is mainly aimed at the adaptability of electrical and electronic products, their original components, various metal materials, and their protective layers for use or storage in a salty and humid environment. It can be used for corrosion tests, as well as to test the degradation of non-metallic materials caused by salt spray, and it can also be used to assess the performance changes of components and equipment in a salt spray environment. This test equipment is mainly used to test products by national standards or user-defined requirements.

Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. was established in 2012, focusing on the research and development, design, and production of textile testing instruments, providing textile testing instruments and services for academic research units and testing institutions. Shanghai Qianshi is currently one of the most competitive and R&D-capable textile testing instrument manufacturers in China. The R&D team is composed of a group of experienced engineers. We are committed to serving customers wholeheartedly and striving to promote technological innovation in textile testing instruments.

Experimental parameters:

1. Temperature range: room temperature +10℃～+55℃

   
   

2. Salt spray precipitation: 1-2ml/h.80cm2

   
   

3. Spray mode: continuous spray, periodic spray, optional

   
   

4. Timing range: 0-99H99M

Experimental principle:

It can be divided into two categories: one is the natural environment exposure test, and the other is the artificially accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a salt spray test box with a certain volume space to create a salt spray environment in its volume space that assesses the salt spray corrosion resistance quality of the product. Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several times or dozens of times that of the general natural environment salt spray content, which greatly increases the corrosion rate and greatly shortens the time to obtain the results of the salt spray test on the product. If a product sample is tested in a natural exposure environment, it may take a year for corrosion to occur, but if it is tested in an artificially simulated salt spray environment, similar results can be obtained in just 24 hours.
