| titleOfInvention | Anti-oxidation treatment method for graphite anode for chlor-alkali industry |
| abstract | The invention relates to an anti-oxidation treatment method for a graphite anode for chlor-alkali industry. The method comprises the following steps of: dissolving 60 to 75 weight percent of sodium metaphosphate, 10 to 20 percent of sodium borate, 10 to 20 weight percent of sodium silicate and 5 to 10 weight percent of sodium carbonate in water to prepare an antioxidant; putting the graphite anode and the antioxidant into a high pressure impregnation tank, ensuring that the graphite anode is immersed in the antioxidant, controlling pressure in the high pressure impregnation tank to be 0.8-1.0MPa, and performing pressure impregnation for 2 to 3 hours; and taking the impregnated graphite anode out, airing at room temperature, and drying in a drying oven at the temperature of between 300 and 350 DEG C to obtain the graphite anode subjected to anti-oxidation treatment. Compared with the prior art, the method is simple; and the service life of the graphite anode treated by the method is 2 to 3 times the original service life, production cost is greatly reduced, and good economic and social benefits are achieved. |
