Abstract

The invention discloses a preparation process of an electrolytic saline solution anode, belongs to the technical field of electrolysis, particularly relates to the field of electrolytic saline solutions, and aims to solve the problems of short service life and low chlorine production efficiency of an existing electrolytic saline solution anode electrode. The preparation process comprises the stepsof (1) welding a titanium-based pipe and a titanium-based plate into a semi-finished anode; (2) putting the semi-finished product anode into a vacuum drying oven, and oxidizing the semi-finished product anode; (3) preparing coating paint, and spraying the oxidized semi-finished product anode by using an electrostatic spraying device after sufficient and uniform mixing; (4) soaking in a mixed solution of ethanol and acetone after spraying, and then placing in the vacuum drying oven for dry baking; and (5) repeating the steps (3) and (4) for 12-18 times to obtain a finished anode. The preparedanode electrode has a chlorine production effect 5%-10% higher than that of an existing electrolytic saline solution anode in the same environment of electrolytic saline solution; and the service lifeof the anode is 20000-30000 hours longer than that of the electrolytic saline solution anode in the prior art.

Description

technical field [0001] A preparation process for an anode of electrolytic salt water, the invention belongs to the technical field of electrolysis, in particular to the technical field of electrolytic salt water. Background technique [0002] Sodium chloride (NaCl) and water (H 2 0) Ionization occurs, and hydrogen gas (H 2 ) and chlorine (Cl 2 ). The remaining hydroxide ions combine with sodium ions to form sodium hydroxide (NaOH). [0003] Sodium chloride is completely ionized in salt water, and water molecules are weakly ionized, so there is Na + 、H + , Cl - , OH - four ions. which is: [0004] NaCl=Na + +Cl - [0005] H2O=H++OH - (Reversible) Under the action of an electric field, the negatively charged OH - and Cl - moving towards the anode, the positively charged Na + and H + Move to the cathode. [0006] At the anode, Cl - than OH - It is easy to lose electrons and be oxidized into chlorine atoms, and the chlorine atoms combine in pairs to form chlo...
