The working principle and application fields of the composite salt spray test chamber are as follows:
1. Working principle
The working principle of the composite salt spray test chamber is based on spraying and constant temperature and humidity control. Specifically, its working principle mainly includes the following steps:
Dissolve water and corresponding salts (such as sodium chloride) in water to form a salt solution. Heat the salt solution to a certain temperature through a heating device to evaporate it into a saturated salt solution. Spray the saturated salt solution onto the surface of the specimen through a pressure device to form a uniform salt spray environment. During the specimen exposure process, the concentration and spraying speed of the salt spray can be controlled by controlling the working state of the heating device and the pressure device, so as to meet the requirements of simulating different corrosive salt spray environments. At the same time, the temperature and humidity in the test chamber are maintained within the preset range through a precise control system to ensure the stability and repeatability of the test conditions. 2. Application fields
The composite salt spray test chamber is widely used in many fields because it can simulate highly corrosive environments, as follows:
Electronic field: The composite salt spray test chamber can be used to test the corrosion resistance of electronic components and circuit boards in marine environments to ensure the normal operation of products in harsh marine environments.
