What is the aluminum anode?
When used as part of a technique called Cathodic protection (CP), an aluminum anode is a conductive rod that is connected to metal structures or installed in metal devices. This part is used to reduce the corrosion of metal objects, including buildings, structures and household appliances such as water heaters. Since the anode is a contact point for lighting the current in the electrical system, this term can also be used to indicate the negative end of some types of non -proechargable batteries.
Corrosion is a chemical process that slowly degrades metal. This process occurs due to the reaction between the metal object and its surrounding environment and becomes more serious underwater or in wet environment. Over time, corrosion can damage the structure sufficiently to endanger its stability, so that engineers often carry out anti -corrosion steps to prevent metal structures from being degraded. One is the location of one or more aluminum anode rods in areas susceptible to corrosion or in JehAbout the proximity, which makes the aluminum anode Vacurifficial anode for a metal structure, in a process called cathodic protection. It works because a more corrosive metal is placed next to a less corrosive metal, it will corrode instead. This technology is often used for ships, bridges and other metal structures that have water contact because it increases the life of the structure by ensuring that the metal remains strong for a longer period of time.
Usually cathodic protection is used in combination with other anti -corrosive techniques such as galvanization. In addition to aluminum, other materials used for cathodic protection in the zinc and graphite or carbon industry are among the materials. The closer the sacrificial rod is placed in the protected metal, the more effective it will reduce corrosion in the area surrounding the sacrificial rod.
Though aninum anode is often used as cathodic protection in production and industrial applications, most often in the homeHe perceives as a sacrificial anode for a conventional water heater. The aluminum anode in the water heater extends the life of the water heater from preventing corrosion. Over time, the sacrificial aluminum anode is corroded and should be replaced to continue to protect the water heater from corrosive damage.
Less often, the anode end can be called an aluminum anode on an aluminum battery. On a conventional battery, the anode is the end that sends the current to the device. Visually, the anode end of the battery seems slightly indented, unlike the positive cathode end of the battery that slightly protrudes, such as the rubber nubby.
