VORRICHTUNG ZUM SCHUTZ GEGEN DIE BIOLOGISCHE VERUNREINIGUNG VON IM MEERWASSER SCHWIMMENDEN OBJEKTEN.

摘要

The current invention relates to an anti-fouling system for objects in contact with seawater which is constituted of the first conductive membrane that is coated on the outer side of the electric insulator mounted at the surface of the object such as ships, marine structures, in contact with seawater, and is composed of thin sheets of metals having low specific resistance or metal oxide, spray-coated membrane, evaporated membrane or fused membrane, and the second conductive anti-fouling membrane having higher electric resistance than the first conductive membrane which is coated on the outer side of the above first conductive membrane and which is composed of the oxidation-resistant insoluble substance and the organic binder, and the power supply equipment that supplies direct currents flowing from the first conductive membrane through the second conductive membrane toward the electric conductor made of iron, copper or carbon located in seawater and opposite the second conductive membrane, owing to the constitution of which the prevention of rise in resistance because of consumption of the conductive membrane, the uniforming of current distribution and a high anti-fouling performance by using the low-resistant conductive membrane are achieved.
