Nest with primary anode

Abstract

An anode system for a cathodic corrosion prevention, comprising a biaxial or multiaxial nest with a number of threads, wherein at least a partial number of the threads comprise carbon multifilaments, shall be provided with a particularly simple and constant primary-anode connection. For that purpose, at least one thread comprises a primary anode.

1 . An anode system for a cathodic corrosion prevention, comprising a biaxial or multiaxial nest with a number of threads, wherein at least a partial number of the threads comprise carbon multifilaments and wherein at least one thread comprises a primary anode. 
     
     
         2 . The anode system of  claim 1 , wherein the primary anode is sewn into a thread, sewn onto a thread, or wound around a thread. 
     
     
         3 . The anode system of  claim 1 , wherein threads of adjacent layers are sewn together at their crossing points. 
     
     
         4 . The anode system of  claim 1 , wherein in the partial number of the threads with carbon multifilaments, these carbon multifilaments are glued together into a thread or are sewn together with a circumferential positioning thread. 
     
     
         5 . The anode system of  claim 1 , wherein the carbon multifilaments or the threads or the nest are provided with an impregnation or coating. 
     
     
         6 . The anode system of  claim 1 , wherein the threads of a layer are arranged spaced from each other. 
     
     
         7 . The anode system of  claim 6 , wherein the spacing of the threads spaced from each other lies in the range of 5-100 mm. 
     
     
         8 . The anode system of  claim 1 , wherein the nest has an area weight per layer of 100-1000 g/m 2 . 
     
     
         9 . The anode system of  claim 8 , wherein the nest has an area weight per layer of 350-650 g/m 2 .
