Prevention of organic growth in the underwater region on steel structures and ships - uses an electric anticorrosion installation where the application of the DC voltage produced is timed

摘要

Method for prevention of organic growth in the underwater region on steel structures and ships, with the use of an electric anti-corrosion installation, is characterised by the fact that application of the d.c. voltage produced by means of a rectifier is timed. The electrical anti-corrosion installation contains a rectifier and at least one external current anode, and respectively a measuring electrode. The rectifier (2) is connected with the external current anod (3) via an adjustable timer (7). It is also connected with a measuring electrode (5) via a measurement result evaluator (6) and a regulator (8). USE/ADVANTAGE -Can be used with ships and steel structures partly or fully submerged. In comparison with the traditional anti-corrosion installations, it is more effective in preventing the formation and hindering the development of organic growths.
