pH adjustment of the frozen saline system
Thread Content
The pH of the calcium chloride saline system is slightly acidic, which causes significant corrosion to the equipment and pipes in the system. Can the pH be adjusted by adding calcium hydroxide?
Calcium chloride corrosion is primarily electrochemical corrosion. As the name suggests, calcium chloride solutions have high electrical conductivity, and chloride ions have a strong ability to penetrate materials. Even when such solutions are made alkaline, they will still corrode upon contact with air, as oxygen-mediated corrosion occurs.
