Reactive corrosion protection systems and methods for making and using the same
This disclosed technology includes a cathodic protection system for protection of metal components. The cathodic protection system can include a non-solid anodic composition, such as an anodic paste. The non-solid anodic composition can include zinc and/or magnesium. The cathodic protection system can include a barrier protection system that can include one or more layers. The barrier protection system can include an outer moisture barrier.
1. A cathodic protection system comprising:
a non-solid anodic composition configured to directly contact a metal component and configured to be non-curably applied to the metal component in paste form; and
a barrier protection system configured to hold at least some of the non-solid anodic composition in direct contact with the metal component, the barrier protection system comprising:
an innermost layer comprising an impregnable substrate impregnated with an amount of the non-solid anodic composition; and
an outermost layer configured to prevent moisture from moving from an external side of the outermost layer to an internal side of the outermost layer.
2. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises zinc.
3. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises zinc having a concentration greater than or equal to about 65 wt %, by weight of the non-solid anodic composition.
4. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises zinc having a concentration greater than or equal to about 90 wt %, by weight of the non-solid anodic composition.
5. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises magnesium.
6. The cathodic protection system of claim 5 , wherein the non-solid anodic composition comprises magnesium having a concentration greater than or equal to about 65 wt % by weight of the non-solid anodic composition.
7. The cathodic protection system of claim 5 , wherein the non-solid anodic composition comprises magnesium having a concentration greater than or equal to about 90 wt % by weight of the non-solid anodic composition.
8. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises zinc and/or magnesium, the zinc and/or magnesium combining to have a concentration greater than or equal to about 65 wt % by weight of the non-solid anodic composition.
9. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises copper carbonate, solubilized copper, or a combination thereof.
10. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises an electrochemically-activated pigment configured to provide a visual indication of a voltage differential current.
11. The cathodic protection system of claim 1 , wherein the barrier protection system is flexible.
12. The cathodic protection system of claim 1 , wherein the impregnable substrate comprises bonded zinc wool or unbonded zinc wool.
13. The cathodic protection system of claim 1 , wherein the outermost layer comprises a hydrophobic material.
14. The cathodic protection system of claim 1 , wherein the outermost layer comprises an impermeable material.
15. The cathodic protection system of claim 1 , wherein the outermost layer comprises an ultraviolet-protectant material.
16. The cathodic protection system of claim 1 , wherein the barrier protection system comprises an electrochemically-activated indicator.
17. The cathodic protection system of claim 1 , wherein the barrier protection system further comprises a zinc sheet located between the innermost layer and the outermost layer.
18. The cathodic protection system of claim 1 , wherein the non-solid anodic composition comprises a petroleum thickening agent.
19. A reactive anodic coating system for protection of a metal structure, the reactive anodic coating system comprising:
an anodic paste configured to directly contact the metal structure and configured to be non-curably applied to the metal structure in paste form; and
a multi-layer protection system configured to hold at least some of the anodic paste in direct contact with the metal structure, the multi-layer protection system comprising:
an innermost layer comprising an impregnable substrate impregnated with an amount of the anodic paste; and
an outermost layer configured to prevent moisture from moving from an external side of the outermost layer to an internal side of the outermost layer.
20. The reactive anodic coating system of claim 19 , wherein the anodic paste comprises zinc and/or magnesium, the zinc and/or magnesium combining to have a concentration greater than or equal to about 65 wt % by weight of the anodic paste.
