ADHESION-PREVENTING METHOD FOR OCEANIC CREATURE

摘要

PURPOSE:To strengthen pollution-preventive function by installing a metal plate made of copper or coppery alloy on the surface that touches the seawater and is subjected to protection, and by regularly removing, with a rotary brush or the like, hydroxide or chloride formed on the surface of the metal plate. CONSTITUTION:A plate made of copper or alloyed copper such as cupronickel is installed on the surface that touches the seawater and is subjected to protection. Hydroxide, chloride and others formed on the surface of the metal plate are removed at regular intervals with a rotary brush or the like. Thereby pollution-preventive function of the plate can be maintained for a long period of time.
