Corrosion Inhibitors
Chemical compounds wage war against metal decay in everyday and industrial battles
9 days ago
0
Why does the effectiveness of a corrosion inhibitor depend on the fluid's composition and dynamics?
Because corrosion inhibitors only work at high temperatures regardless of fluid properties.
Because the chemical interactions and flow conditions influence how well the inhibitor can protect the metal surface.
Because corrosion inhibitors permanently bond to metals, making fluid properties irrelevant.
