METHOD FOR ELECTRIC PROTECTION OF METAL OBJECT, GROUNDING ELECTRODE FOR IMPLEMENTING THE METHOD AND COMPOSITION FOR GROUNDING ELECTRODE |
摘要 |
A method for electric protection of a metal object consists in that an extended grounding electrode is placed into an electrolytic medium at a determined distance from the metal object to be protected, the grounding electrode and the object are connected to an electric power source so as to provide for a protection circuit and the metal object is polarized. The electric connection sections and the geometric dimensions and/or electric parameters of the electrode are chosen so that the value of the current propagation constant in the protection circuit does not exceed 10<-3>m<-1>. The grounding electrode comprises an extended central flexible metal conductor (18), an adhesive layer (20) providing for electric contact and an envelope (19) of a hardly soluble polymer current-conductive material based on a composition including a carbon-containing filler 40-80 % by weight, a rubber-based polymer 10-49 % by weight, a plasticizer 9-10 % by weight and an insecticide 0,2-10 % by weight. |
