Working Principle of a Salt Spray Test Chamber

What is a Salt Spray Test Machine? A salt spray test chamber

, often called a salt spray test machine, is used to evaluate a material's ability to withstand corrosion by subjecting it to a saline, hazy environment. This synthetic scenario simulates the kind of real-world environments that a product might encounter, such as an industrial environment with chemical exposure or a humid coastal location. This test assists manufacturers in determining how long their products can endure exposure to harsh substances. Working Principle of a Salt Spray Test Machine So, how does a salt spray test machine work? It essentially simulates an accelerated corrosive environment by atomizing a saline solution into the chamber. Saline Solution: A mixture of water and sodium chloride (NaCl) is heated and sprayed into the chamber to create a salty mist. Compressed Air Atomization: Compressed air passes through nozzles to create fine mist particles, which settle on the product, replicating the corrosive atmosphere found in coastal or industrial environments. Temperature and Humidity Control: The machine maintains a controlled temperature—usually between 35°C to 48°C—and regulates humidity levels to simulate various environmental conditions. Continuous Monitoring: Our advanced machines have sensors and controls that continuously monitor conditions within the chamber to ensure that the test is consistent and accurate.
