1. Preparation process of titanium anode
1.1 Coating and firing
According to different application requirements, the halides of Ru, Ir, Sn, Ti, Pd, Ta, Co, Ni, etc. are made into alcohol solutions in different proportions → coating → drying → oxidation firing, and repeated many times to make Required anode → quality inspection → delivery.
1.2 Surface treatment of titanium substrate
In order to increase the effective area of the substrate and enhance the bonding force between the coating and the titanium substrate, it is usually boiled with 10% to 15% alkali or washing powder to remove oil, and then boiled and etched with 10% to 15% oxalic acid.
2. History of titanium metal anodes
my country started the research on metal anode electric cells in 1972. In 1974, mercury electric cells passed the appraisal in Tianjin. In 1975, they passed the appraisal of 20 m2 metal anode electric cells in Shanghai. By the first half of 1987, 30-type industrial electric cells It has reached more than 1,600 units, and the production capacity has accounted for 1/3 of the world, making my country's caustic soda production rank fifth in the world. By 1996, my country's caustic soda output reached 5.32 million tons, ranking third in the world. The output produced by metal anode cells has accounted for more than 80% of the total output.
The electrolysis industry has used graphite as an anode for 100 years. With the development of the industry, titanium anode companies believe that the limitations of graphite anodes, such as high energy consumption and short life, are becoming more and more obvious. People always want to develop a more Ideal anode material to replace it. As early as 1901, a patent for platinum plating on Pb was published, and in 1909, a patent for platinum plating on graphite was published. In 1950, the Dutchman Henry Bill published the article on titanium-based coating titanium-noble metal film a few weeks before D.B Cotton and C.H Angell of the British Ici company. The American Olin company started the laboratory in 1957 for the purpose of industrial production. research, and cooperated with Ici in 1960 to apply its research results to mercury electrolyzers. In 1965, Bill obtained the patent right of RuO2 coated anode. In 1968, the research results of Bill's RuO2-TiO2 coating were industrialized in the chlor-alkali plant of de Nora company in Italy. This oxide coating anode was commercially called D.S.A. (Dimensonally Stable Anode). By 1980, the whole 50% of the world's chlor-alkali industry has replaced graphite anodes with DSA, and currently 70% of the cells have been changed to metal anode cells [1-3].
Titanium Anode Company learned that DSA has the advantages of energy saving (>23%), high productivity, maintenance cost saving, labor intensity reduction and obvious environmental benefits in the chlor-alkali industry, which has aroused the interest of other electrochemical workers. A large number of new anode coating materials and application development research have been carried out, and so far they have been obtained in various fields such as water treatment, metal foil preparation, chlorate preparation, metal surface treatment, cathodic protection, electroplating, seawater decontamination, etc. application. Electrochemical and materials workers in our country have also done a lot of work.
