Galvanic anode provides cathodic protection current
by means of self-dissolving in the corrosive medium when it
is electrically connected to the protected object. A galvanic
anode material should possesses following conditions:
1. Enough
negative and steady potential.
2. Low
anode polarization in work, dissolving uniformly, the corrosion
product may detach on its own.
3. High
current efficiency.
4. High
electrochemical equivalent
5. The
corrosion products is nonpoisonous, no pollution to the environment.
6. Cheap,
convenient sources.
The commonly used galvanic anode materials are zinc based, aluminium
based and magnesium based alloys. Their chemical compositions
and electrochemical performance are different, and then their
applicable environments are different.
QRIMC has been engaged in the research and production of galvanic
anode for a long time and is able to produce all commonly used
galvanic anodes. QRIMC has developed bracelet type galvanic
anode specially for pipelines; high efficiency aluminium alloy
galvanic anode for diluted sea water, soil and sea mud; special
aluminium alloy galvanic anode for high temperature environment;
galvanic anode for small pipeline and high potential magnesium
anode for high electric resistant soil.
Our galvanic anode products are widely
applied to fields of harbor, port, ship, ocean artesian well
facility and plantform, power plant, refinery, chemical plant,
and civicism burying pipeline, long distance buring pipeline,
etc. Besides, it is sold to Singapore, Japan, America, Austrilia,
Iraq, Pakistan, etc. ĄŁ
