Zinc alloy sacrificial anodeThe cathodic protection method of zinc anode is to connect a metal or alloy that is more likely to lose electrons to protect steel equipment. For example: the protection of steel gates, some use this method. It is a more active metal, such as zinc, which is attached to the steel gate. In this way, when galvanic corrosion occurs, the metal that is more active than iron is corroded, and iron is protected. Usually, a certain amount of zinc blocks are installed at the stern of the ship and below the waterline of the hull to prevent the hull from corroding. This is the method used.Product features: low self-solubility, high current efficiency, wide application range. At present, electrochemical protection is not only used to protect steel equipment in sea water or rivers, but also to prevent corrosion of cables, petroleum pipelines, underground equipment, and chemical equipment. Aluminum alloy sacrificial anodes are suitable for cathodic protection of metal corrosion protection for ships, mechanical equipment, marine engineering and seaport facilities in seawater media, pipelines, cables and other facilities in sea mud, and soil media with low resistivity.Precautions for use: 1. Keep the surface clean. 2. When using in the soil, the soil resistivity should be less than 15 ohm·m, and it is recommended to use it with a special packing packageSacrificial zinc anode chemical compositions : elementAlCdothersZnFeCuPbSi%0.3-0.60.05-0.12≤ 0.005≤ 0.005≤ 0.006≤ 0.125The balance Aluminum alloy sacrificial anodeProduct features: light weight, high current efficiency, and low cost.Scope of application: suitable for ships, marine engineering, seaport facilities, steel pile wharfs, submarine pipelines and circulating water in power plants in seawater media System, crude oil storage tank, water deposits, etc.Precautions for use: 1.

The replenishment of chromium in the chromium plating process is achieved by directly adding chromate to the plating solution. Unlike zinc plating, which requires anode dissolution to provide zinc ions, chromium plating does not require anode dissolution, which means that chromium plating requires insoluble anodes. Lead-tin alloy is used, and some antimony is sometimes added.Lead tin alloy rod anode/ lead stibium antimony alloy anode/ Pb Sn Sb alloy anode/electrode application: Chrome plating; Electro-polishingLead tin alloy rod anode/ lead stibium antimony alloy anode/ Pb Sn Sb alloy anode/electrode features:1. Dense internal structure, no cold barrier, shrinkage cavity, shrinkage porosity. 2. It has been extruded many times by special calendering equipment, which has high strength, is not easy to bend and deform, and at the same time improves the conductivity of the anode. 3. Due to the use of rolling production technology and the increase of tin content, its corrosion resistance has been improved, the surface is not easy to generate lead chromate and passivation, and the anode slag is less, making the plating solution cleaner. 4. The alloy composition is uniform and there is no segregation phenomenon, and the conductivity is uniform, which improves the uniformity of the chromium plating layer thickness.5. The connection between the copper hook and the lead-tin rod is coated with glue, so the copper hook will not be corroded. 6.

Pb alloy rolling plate, with uniform crystal structure, is better in anti-corrosion and mechanical performance stability. The hanger bar which is certain mm thickness Pb cladding around Sn electro-plating on copper bar, has better anti-corrosion to acid mist during electro-winning. Pb plate connects to hanger bar through two-side welding with Pb cladding, or plate plug-in welding. we also have the Ti-MMO anode. It has better mechanical strength, lower solubleness in the acid, lower resistance, high current with no deformation, maintainability and long-life. It's used to apply in the harsh working environment.

In the past years, Elegant stainless steel/ titanium cathodes are widely used in domestic and overseas Copper&Nickel electrowinning plant for its excellent performance as below: 1. The connection area between Copper and S.S is considerable, thus contribute to a less lose of electric power.2. High mechanical strength design of hanger bar to prevent scratching, sinking mark and bending.3. Hanger bar designed with good heat resistance to avoid deformation or degenerate, hanger bar can resistance high temperature up to 700°C cause by short circuit.4. The laser welding between S.S blank/ Titanium plate and hanger bar can help avoiding the welding gap, thus can maximum prevent welding corrosion. The average service lifetime of cathode is 10-15 years. 5. By powerful extrusion, the edge strip is deformation free with long lifetime and easy for maintenance.6. The performance of edge clip bar was stable which can decrease the cost.Cathode is widely used in Zinc, Copper, Nickel, Cobalt and Manganese EW/ER industry .Copper can be easily deposit on the stainless steel cathode surface and be stripped by auto-stripping machine. The use of stainless steel cathode can save a lot of time and human cost compared to starting sheet. It's an obbligato part in large scale and modernization Copper electro-refinning and Copper electro-winning plant.MaterialBlank:material - 316L stainless steel plate, Gr 1 or Gr 2 Titanium plate; Hanger bar:Stainless steel cladding around copper bar(Cu-SS)Copper electro-plating stainless steel bar(SS-Cu)Triple layer (CS-Cu-SS)Al cladding Copper ingot, welding to Al barTitanium clad copper bar (Ti- Cu)Edge strip:PP by mechanical process or extrusionAdvantagesHigh strength and anti-corrosion hanger barAdvanced edge strip with round bar for fasteningSpecial surface polishing treatment to form a passive film90° "v" shape groove at bottom of blank, Copper cathodecan be more easily stripped in the bottom10~15 years service lifetime of blank, 1.5year of edgestrip (If Cl- < 40mg/L)Double side full welding technologyWeldingPerfect welding technology (Double-side full laser welding) is used to connect stainless steel blank / Titanium plate with hanger bar. It does not use flux to connect, which is successful to avoid the weld seam defects and maximize preventing corrosion. A hanger bar for a cathode plate and a method of producing a cathode for electrolytic recovery of metal. The hanger bar comprises a support element which is preferably stainless steel and hollow. An electrically conductive metal cladding is affixed the stainless steel bar by any appropriate mechanism, eg interference fit, welding, chemical or mechanical fastening or coextrusion or roll forming. Affixing the cladding to the stainless steel support element has significant advantages over conventional electroplating techniques including that a more precise engineering specification can be applied to the cladding thickness. This is important to maintain vertical alignment of the cathode plate in the electrolytic cell.Permanent Stainless Steel/titanium Cathode Plates
