(Summary description)There are three main reasons for the discoloration, oxidation and blackening of copper wire: 1. Oxidation. 2. Sulfuration. 3. Chlorination. The color changes from light to dark. Oxygen. Sulfur. Chlorine mainly comes from the ambient atmosphere or other materials. Oxygen. Sulfur. Chlorine reacts to the copper wire as follows. : 1. The copper oxide copper wire reacts with oxygen in the air to first produce brown-red cuprous oxide, which is further oxidized to black copper oxide, and the temperature is high. High humidity accelerates the oxidation of the copper wire. 2. Copper wire and sulfide The reaction of a. Copper reacts with S2- to form purple-red cuprous sulfide, and further reacts to form black copper sulfide. b. Copper reacts with sulfur dioxide and oxygen to form salt-colored copper sulfate. 3. Copper wire reacts with chloride ions It reacts with chloride ions to form a brown-yellow chloride, which is further oxidized and blackened.
