Abstract

The invention discloses an electrochemical antiseptic device using a latticed titanium anode and a protection device. A protection cover is arranged on the upper surface of a reinforced concrete member; an electrolyte solution is placed in the protection cover; a metal net is arranged on the inner side of the protection cover; an anode of a direct-current power supply is connected with the metal net through a wire penetrating through a first open hole, and a cathode of the direct-current power supply is connected with a reinforcing steel bar through the wire penetrating through a second open hole, so that an electrical circuit is formed. The protection cover with adjustable area is adopted to place the electrolyte solution, and can be adjusted aiming at different conditions, so that the application range is wide, and meanwhile, the defects of small single working range and low efficiency in existing chloride ion dissociation are overcome; the lithium hydroxide electrolyte are adopted, so that the possibility of alkali-aggregate reaction is less than the possibility by adopting a calcium hydroxide solution; the metal net at the sacrificial anode part adopts the titanium metal net, which cannot be corroded, can also be recycled, and cannot produce pollution on the concrete surface.

Description

technical field [0001] The invention relates to an anti-corrosion device, in particular to an electrochemical anti-corrosion device and a protection method using grid-like titanium anodes. Background technique [0002] Coastal reinforced concrete structures are located in harsh corrosive environments such as seawater and marine climates, and there are a large number of chloride ions that are corrosive to steel bars. Therefore, their engineering life has not been able to meet the requirements that people expect when designing. Anti-corrosion problems, especially chlorine in the structure The extraction of ions is a rather serious problem to be solved. Due to the serious damage caused by chloride ion corrosion to concrete structures, the annual investment in the prevention and treatment of steel bar corrosion in reinforced concrete structures in various countries is very large. Beijing Xizhimen Overpass was completed and put into use in 1979. Less than 20 years ago, the corro...
