Marine aluminum alloy sacrificial anode Aluminium alloy sacrificial anode wholesale

Most of them are used for cathodic protection of metal structures or the bottom plate of crude oil storage tanks in seawater environments, and cannot be used in soil environments with low chloride ion content (for indium-containing anodes, chloride ion content is greater than 1000ppm; Mercury anode 10000ppm). The electrode potential is -1.05V CSE. When the temperature is higher than 49℃, the capacitance decreases with the temperature, which can be referred to the formula: Z=2500-27 (T-20), (T anode operating temperature ℃). In salt water, the current capacity may be reduced by half. The aluminum anode is fixed directly to the protected structure without filler.

High electrochemical performance, the unit weight of the anode material power generation is large, about 3 times that of zinc anode, magnesium anode 2 times. In seawater and other media containing chloride ions, it has good performance and strong self-regulating ability of sending current.

Aluminum alloy sacrificial anode is suitable for cathodic protection against metal corrosion of ships, machinery and equipment, Marine engineering and port facilities in seawater medium, and pipelines, cables and other facilities in sea mud.
