Description
Technical field
The utility model belongs to the marine anti corrosion technology field, specifically relates to a kind of for the etch-proof protector of marine structure.
Background technology
Because ionogen characteristic, the marine life of seawater adhere to and the factor such as seawater scouring, so that the marine structure of metallic substance very easily is corroded in ocean environment.According to statistics, the direct economic loss that China suffers because of corrosion every year accounts for 4% of GDP, and wherein, the direct economic loss that the corrosion under the ocean environment causes is the most serious, is about 1/3 of all corrosion financial losses.2011, China GDP is about 7,000,000,000,000 dollars, can calculate this year China by these data and reach 1,000 hundred million dollars because of the direct economic loss that ocean environment corrosion causes, and this year 7000 hundred million dollars of China's marine economy insufficient total amounts, that is to say that the direct economic loss that corrosion causes under the ocean environment accounts for more than 10% of marine economy total amount.In fact, if the expense that the indirect economic loss that corrosion is caused such as maintenance prevention produce, because maintenance causes the loss of stopping work and causes the expense such as accident all to be taken into account because corrosion causes the facility structure undercapacity, total financial loss can be larger.
In order to reduce the impact of marine corrosion; prolong offshore drilling platform; the work-ing life of the marine structures such as oil-gas mining platform; need to take certain anti-corrosion measure; and in numerous marine anti corrosion technologies; impressed current protection cathode method technology comparative maturity; the method principle of work is: in electrolyte environment; connect external dc power supply; a large amount of electronics are forced to flow on the protected metallic substance marine structure after the energising; the accumulation that makes the protected object surface produce negative charge; as long as external dc power supply voltage is enough, metallic corrosion and the galvanic current that produces just can not be transferred, thereby prevented corrosion of metal.The method has advantages of that protection period is long, protection domain greatly, is not subjected to the restriction of environment resistivity, is applicable to be positioned at for a long time facility under water.The shortcoming of the method is: the DC power-supply system that needs a cover to continue; but because expensive by the undersea cable power supply; the output electric weight is limited, and implementing method that the impressed current protection cathode method protects marine structure to avoid corroding by cable power supply, to be difficult to establishing afloat be not that too important facility and the facility of some marine no supervisions are promoted.
