Marine Anti-corrosion Magnesium Anode
Magnesium alloy sacrificial anode is a method to protect the metal structure from corrosion by using the electrochemical reaction between metals to sacrifice itself to prevent being corroded. This method through the conductive contact, the magnesium alloy will touch the metal components that need to be protected, so that the magnesium alloy corrodes itself, generating electric current, thus forming a layer of protection, to achieve the effect of anticorrosion.
Overview
Applications
1. Anti-corrosion of ships: Magnesium alloy sacrificial anode is widely used in seawater system of ships, such as radiator, cooling water pan, cooling water pipe, etc., to avoid corrosion of metal structure of ships by marine environment.
2. Anti-corrosion of marine platform: magnesium alloy sacrificial anode is also widely used in anti-corrosion of metal structure of marine platform, such as offshore oil platform, submarine pipeline and so on.
3. anti-corrosion of oil field drilling rigs: oil field drilling rigs are usually corroded by water, and the common method is to use magnesium alloy sacrificial anode to protect the sodium equipment exposed from the ocean and prolong its service life.
4. Boiler anti-corrosion: in the production process, often need to use chlorine-containing raw materials, these raw materials after oxidation reaction will form the boiler metal components have corrosive effect on the acidic gas. Through the anti-corrosion method of magnesium alloy sacrificial anode, it can effectively improve the service life of the boiler.
How to Select and Use Magnesium Alloy Anode
1. selection of magnesium alloy: when choosing magnesium alloy sacrificial anode, it is necessary to consider the conductivity of water, water hardness and other factors to ensure that the magnesium alloy can produce sufficient current density to ensure the protective effect.
2. Installation of magnesium alloy: for the overhead facilities such as ships and marine platforms, it is necessary to use messy magnesium alloy strips for fixing; for the horizontal facilities such as boilers and other facilities, it is necessary to use heavy-duty magnesium alloy blocks for fixing.
3. Replacement of magnesium alloy: when the magnesium alloy sacrificial anode is corroded to a certain degree, it needs to be replaced in time to ensure that the metal structure is always protected.
