Every year millions of people all over the world enjoy themselves in swimming pools. The traditional method is to use chlorinated chemicals to produce hypochlorous acid for disinfection. At present, a new industrial technology of hypochlorous acid production, chlor-alkali process began to be applied. This method is to make the current through the electrolyzer containing sodium chloride (NaCl) solution, the anode to generate chlorine (Cl-) ions, the cathode to generate hydroxide (OH+) ions, like the traditional chlorination products, this method can also generate chlorine gas. The electrolytic cell eventually produces substances including chloride ions, hydrogen ions and hypochlorous acid. The use of this salt-chlorinated system of disinfection system can effectively reduce the corrosion rate of swimming pool equipment and the bleaching and bleaching damage to swimsuits, but also because of the use of soft water, the system can greatly reduce the effect of skin irritation. The insoluble titanium anode coated with ruthenium, iridium and titanium provided by kaida can be used as a chlorine disinfection device for water electrolysis in swimming pools. The biggest advantage of the mixed oxide coating titanium anode (MMO) is that it can greatly improve the efficiency of chlorine production and has excellent stability. The coating is firmly combined with the substrate and the service life is long. Another unique advantage of kader in titanium anode is that the precursors of the coating material completely belong to its own technical achievements, combined with the international standard titanium substrate processing means and advanced coating technology, so that the product has a higher cost performance.
