Different Types of Anode Rods
Magnesium
Magnesium anode rods are the most common type of anode rod. They
are used in places where water is softer. They do not last very
long when you have hard water, a couple years at best. This is the
main reason water heaters don't last long after the anode rod is
eaten up.
Aluminum
Aluminum anode rods are best for places with hard water. The
aluminum rod will withstand harder water than any other type.
Aluminum may be a health problem, so to be safe you may not want to
drink hot water and make sure to run some cold water through the
faucet spout before drinking the water. Keep in mind, our sodas
come in aluminum cans too.
Zinc
Zinc anode rods are really just aluminum anode rods with a small
portion being zinc. The ratio of zinc to aluminum is 1:10. The
reason zinc is added is to combat any sulfur smell coming from the
water. A new water heater is never installed with a zinc anode rod
already in it, but it is a good upgrade if you experience rotten
egg smell coming from your hot water.
The role of the sacrificial anode rod
The anode rod is the most important factor in determining the life
of your water heater. An anode rod is a steel core wire surrounded
with one of three different metals. These metals include aluminum,
magnesium, and zinc. The rod is screwed into the top of your water
heater and protects your water heater from rusting. When the tank
is filled with water the anode rod sacrifices itself to protect the
exposed steel of the water heater, through a method called
electrolysis. Electrolysis happens when there are two pieces of
metal connected inside of water, the process makes the anode rod
corrode in place of the exposed steel in your water heater. During
this process the more noble (less reactive) metal will corrode over
the less (more reactive) noble metal. Aluminum, magnesium, and zinc
are all much less noble than steel, meaning they will corrode
before the steel, which is why they are used for anode rods.
Magnesium Rod Anode are produced in a variety of shapes and sizes
for use in water ,water container,boiler ,pre-polarization of steel
structure in seawater.Gas pipe,Anti-corrosion of steel and iron
structure where high resistant and electrolyte existed.
1.Technology :
Extruded Magnesium Anode
Cast Magnesium Anode
2.Standard: ASTM B 843-1995
3.Features :
Magnesium anode is used in technical method of electrochemistry
cathode protection. theory is from that connect with the protected
metal body ,with the exhausting and dissolving of negative metal
material or alloy ,protective curer body will be protected from
corrosion . Mg anode can produce higher quality potential power, is
ideal sacrificial anode materials.
