Aluminum alloy sacrificial anode has the advantages of light weight, large current, negative potential and low price. It is used in the cathodic protection of metals in marine media, such as ships, harbor engineering and marine engineering facilities, seawater cooling water system and storage tank deposition water parts, offshore oil production system, petrochemical processing pipeline, high temperature sea mud, submarine pipeline and other industrial fields.
Through the control of alloy composition and casting conditions, Guangyu controls the selection of raw materials, charging sequence, melting equipment, casting process and quality inspection of Al - Zn - In alloy sacrificial anode The sacrificial anode materials with uniform surface dissolution, non passivation, high temperature resistance (50 ℃), good electrochemical performance and reduce environmental pollution.
Anti-corrosion products are available both in land and in the sea. In recent years, with the increasing saturation of terrestrial anti-corrosion areas, product orders have increasingly turned to "maritime anti-corrosion" phenomenon, in addition to the traditional aluminum anode, zinc anodes occupy more and more The "additional current yin and anti-corrosion scheme" with better green defense for the marine environment has also become a popular fried chicken!
The density of aluminum is 2.7g/cm3, the open circuit potential is about -1.05V, the current efficiency is more than 70%, △E=0.25V, and it is usually applied in water with a resistivity of less than 150Ω NaN. The aluminum anode is usually not used in the soil.
