Titanium anode for chlor-alkali industry / titanium anode for chlorate industrial / coated titanium anode

The electrolyzed salt solution is used to produce caustic soda, the anode is made into chlorine gas, and the cathode is reacted to produce hydrogen and caustic soda. According to the product separation method, the chlor-alkali industry forms two different production processes: ion-exchange membrane electrolysis (diaphragm electrolysis cell) and mercury electrolysis The anode reaction of the two electrolysis methods is basically the same, but the cathode reaction is different. The mercury electrolysis method uses mercury with a high hydrogen evolution potential as the cathode material. Before the hydrogen evolution electrode potential is reached, the NA+ in the solution has a sodium discharge in the cathode and sodium is formed in the mercury. Amalgam. Compared with the graphite electrode, the diaphragm method produces caustic soda, the working voltage of the graphite anode is 8A/DM2, and the coated anode can be multiplied by up to 17A/DM2. In this way, the product can be multiplied in the same electrolytic environment and the quality of the produced product is high, and the purity of the chlorine gas is high.
