適用しても効果がない。On the other hand, in order to prevent mussels from adhering to the bottom of the ship, a conductive coating film is applied to the bottom of the ship, and this is used as a positive electrode. A method of energizing as is known. However, this method
It is effective for small vessels, but not enough for large vessels. The reason for this is that it is necessary to supply a current with a sufficient current density to the entire conductive coating film for the antifouling effect, but this is possible because the conductive coating stays within a few ten meters from the conducting end.
(S & T, July 1990, Vol. 3, No. 3, 39-44). Therefore, even if this method is applied to an intake pipe having a length of several hundred meters as it is, there is no effect.
