Offer Description - ZINC / ALUMINIUM ANODE



Place of Origin: Propinsi Jawa Timur Indonesia Brand Name: CP Model Number: CZ - 8



ZINC AND ALUMINIUM CP ANODE IS DEFINED AS REDUCTION OR ELIMINATION OF CORROSION.

If two different metals are physically or electrically and i mm ersed in electrolyte then some amount of current flows between the two metals.

This current is supplied by one of the metals by e mm iting metal ions to the conductive environment. This is known as galvanic corrosion which destroys base metals rapidly. Aluminium was considered to be the best candidate for such an anode because of its theoretically high ampere- hour capacity per kilogram. Aluminium CP? anode is one of the most effective ways of reducing or eliminating the corrosion damage that invariably affects metals (iron particular) that are in contact with sea water. Paint provides only limited protection for ships hull, so an effective cathodic protection system must be employed using sacrificial anodes, impressed currents, or a combination of both. CP? anode has the right products to protect one of these ! CP? anode produces a vast range of high quality sacrificial zinc and aluminium anodes are designed to offer a constant and measurable protection on ships of all size. Why Aluminium CP? anodeOffshore ??

Properties of aluminium CP? anode that make them stand out from other seawater anodes : 1. Highcurrent capacity under variable conditions. 2. Currentcapacity maintenance with time. 3. Desirableoperating potential. 4. Constantpotential with time (no polarisation) . Current capacity characteristics : The current capacity of an anode is a very important consideration in anode selection because it is ampere hours per unit currency that the corrosion engineer is buying for any cathodic protection system. Field testing of the aluminium CP? anode has proved its reproducible current capacity under the full range environmental and operational variables encountered in sea water.
