Working Principle Of Salt Spray Test Chamber

A salt spray test chamber assesses the corrosion resistance of materials by simulating a salty and humid environment (such as a 5% sodium chloride solution). Its core process includes: preparing the salt spray solution (glacial acetic acid can be added to enhance the acidic environment), generating uniform salt spray using an atomization device (droplet size is controllable), and precisely controlling the temperature and humidity inside the chamber (e.g., 35±2℃) and the salt spray deposition rate (1-2 ml/80cm²·h). After sample exposure, the degree of corrosion is quantified by measuring weight loss or electrochemical testing (e.g., coating corrosion resistance time ≥96h), providing data support for improving anti-corrosion processes for industrial products such as automotive parts and electronic components.
