What is the corrosive effect of chloride ions on copper or copper alloys?
Thread Content
In the gypsum slurry resulting from desulfurization in power plants, the chloride ion concentration is generally between 20,000 and 4,000 ppm. For certain components that are exposed to this solution for extended periods of time, is it possible to use copper material? Is there a suitable copper alloy that can resist chloride corrosion? What is the degree of corrosion for ordinary copper alloys? I seek advice from experts!
Copper material should not be used, as chloride ions are acidic anions with high reactivity, which accelerates the corrosion of copper. Consider anti-corrosion treatment for the fasteners and adding a coating.
Tank equipment is generally made of fiberglass; using copper would result in much higher costs.
