Water Injection System: A water pump injects prepared brine into the brine tank within the test chamber. The brine is typically prepared according to a specific ratio (e.g., 5% sodium chloride solution) to ensure the accuracy and repeatability of the test.
Heating System: After entering the brine tank, the brine is heated by an electric heater, causing it to evaporate and generate water vapor. The heating temperature is set according to the test requirements, typically around 35°C.
Airflow Regulation System: After passing through the heater, the water vapor is regulated by an airflow regulator to ensure a uniform flow rate and velocity of the water vapor entering the test chamber. This ensures the stability and consistency of the salt spray environment within the test chamber.
Salt Spray Generation and Spraying: After the regulated water vapor enters the test chamber, it mixes with compressed air and is converted into fine salt spray particles through nozzles or atomizers. These salt spray particles are evenly sprayed onto the test samples, simulating salt spray corrosion in a marine environment.
Test Procedure: The test samples are placed inside the test chamber and exposed to the salt spray environment for testing. Test time, temperature, humidity, and other parameters are set according to test requirements to ensure the accuracy and comparability of test results.
Exhaust System: After the test, the salt spray gas in the test chamber is discharged through the exhaust system to facilitate the next test or to clean the test chamber.
