Product Description: Hull Commonly Used Sacrificial Anode Zinc Block ZH-1Zinc-aluminum-cadmium alloy sacrificial anodes are suitable for the cathodic protection of metals against corrosion in seawater, brackish water media for ships, mechanical equipment, marine engineering, and port facilities, as well as for pipelines, cables, and other installations in low-resistivity soil.Jiaozuo Libo Anti-Corrosion Materials Co., Ltd. is a professional company integrating the development, production, and sales of anti-corrosion materials for cathodic protection, along with comprehensive anti-corrosion design, construction, installation, and technical services. With excellent service quality and a smile, we offer现货供应 installation guidance. Choose Libo products with confidence for放心选购.The corrosion of steel in near-neutral humid air属于吸氧腐蚀 (the same applies in seawater):Negative electrode (Fe): 2Fe - 4e = 2Fe2+Positive electrode (C): 2H2O + O2 + 4e = 4OH-Overall reaction equation: 2Fe + O2 + 2H2O = 2Fe(OH)2The role of attaching anti-corrosion zinc blocks is to protect by sacrificing the zinc block. Since zinc is more reactive than iron, zinc优先失去电子 and reacts first. However, zinc blocks need to be replaced regularly. Proper installation ensures good electrical contact with the hull. When installing zinc blocks, the outer hull is usually already painted.Hull Commonly Used Sacrificial Anode Zinc Block ZH-1 Our company has long been producing and selling zinc blocks, zinc anodes, sacrificial anodes, magnesium anodes, aluminum anodes, zinc alloy anodes, etc. Welcome your patronage! Our products are widely used for the cathodic protection of ships, port facilities, marine engineering, buried metal pipelines, storage tanks, seawater cooling water systems, and other steel structures (Due to fluctuating metal prices, please inquire for the current price). We welcome both new and existing customers to call for咨询!Jiaozuo Libo Light Alloy Co., Ltd. has years of experience in producing zinc blocks, zinc sacrificial anodes, and various other materials of sacrificial anodes, with considerable expertise in anti-corrosion.

Feel free to call for咨询 and orders. Marine zinc anodes are available with single iron foot, double iron foot welded, and bolt-type connections.Hull Commonly Used Sacrificial Anode Zinc Block ZH-1 We produce external hull anti-corrosion zinc-aluminum-cadmium alloys, fixed zinc-aluminum-cadmium alloys, ballast tank zinc-aluminum-cadmium alloys, oil field anti-corrosion zinc-aluminum-cadmium alloys, aluminum-zinc-indium series alloys, zinc-aluminum-cadmium alloy sacrificial anodes, aluminum ingots, zinc blocks, sacrificial anodes, anti-corrosion zinc blocks, anti-corrosion aluminum blocks, aluminum alloy anodes, zinc alloys, die-cast zinc alloys, zinc anodes, aluminum anodes, zinc rods, die-cast sacrificial anodes, sacrificial anodes for yachts, zinc alloy rods, etc.The use of zinc as an anti-corrosion metal has a long history. It is well-known for protecting ship hulls, boilers, and the outer walls of internal combustion engine cylinders. However, further exploration into materials and installation has only occurred in the last 20 years. During this time, technologically advanced countries like the United States have made improvements in materials and dimensions, while China has also continuously achieved results in research on zinc for impressed current anodes. The performance of anti-corrosion zinc with微量添加镉 and aluminum has become increasingly effective, with these studies based on high-purity zinc. The principle is sound: zinc corrodes before iron, and ships in the ocean also附带锌块. However, this is feasible during use for your own vehicle, but it would be more complicated for manufacturers to implement this approach. more>

Product Description: How much does the RBX HK-1050 Home Theater Karaoke Sound System cost?The HK Series 2.1/5.1 Home Theater K System is a product designed to resemble traditional bookshelf speakers. Why did we retain the appearance of classic bookshelf speakers? The reason is simple: bookshelf speakers blend more seamlessly with rosewood furniture. Through careful market analysis, we found that some villas lack dedicated home theater or karaoke rooms, forcing homeowners to use the living room as a multipurpose family space. Professional speakers often clash with the interior decor and furniture style in such settings. This is why some homeowners prefer to forgo such speakers rather than compromise their interior design. The HK Series Bookshelf-style Theater K Audio System meets the needs of these customers.How much does the RBX HK-1050 Home Theater Karaoke Sound System cost? more>

Product Description: High-Quality Double Iron Foot Marine Zinc Block | Anti-Corrosion Zinc Block ZH-8Supply marine zinc alloy sacrificial anodes in accordance with the standard: GB/T4950-2002, also known as zinc alloy anodes or zinc alloy sacrificial anodes. Main applications: Zinc sacrificial anodes are suitable for the cathodic protection of metals against corrosion in ships, mechanical equipment, offshore engineering, and port facilities in seawater and brackish water environments, as well as for pipelines, cables, and other facilities in low-resistivity soil. Implementation standards: Zinc anode specifications are categorized by use: 1. Welded sacrificial anodes for ship hulls (single iron foot) 2. Welded sacrificial anodes for ship hulls (double iron foot) 3. Bolted sacrificial anodes for ship hulls 4. Common sacrificial anodes for ballast water tanks 5. Sacrificial anodes for port and offshore engineering facilities 6. Long strip sacrificial anodes for seawater cooling systems 7. Disc-shaped sacrificial anodes for seawater cooling systems 8. Sacrificial anodes for buried pipelines r139391915High-Quality Double Iron Foot Marine Zinc Block | Anti-Corrosion Zinc Block ZH-8IntroductionZinc sacrificial anodes are commonly used in soil environments with resistivity less than 20 ohm·meters or in seawater environments. The electrode potential is -1.10V CSE, with a driving voltage of 0.25V. When the temperature exceeds 49°C, intergranular corrosion occurs. Above 54°C, the electrode potential of zinc anodes becomes positive, reversing polarity with steel: the zinc becomes the cathode and is protected, while the steel becomes the anode and corrodes. Therefore, zinc anodes are generally used in environments below 49°C. Zinc anodes must be used with backfill material.A zinc grounding battery consists of two or four 1.5m long zinc rods, separated by insulating spacers and bound together with tape, all embedded in conductive backfill material. During application, the cable leads connected to the steel core are attached to both sides of the insulated component to provide a low-voltage bypass circuit. Typically, its resistance in water-saturated conditions is 0.2-0.6 ohms. If the resistance of the two-rod type does not meet requirements, a four-rod type battery can be used.The materials for zinc grounding batteries are the same as the composition of zinc anodes. The backfill material formula is: 75% gypsum powder, 20% bentonite, and 5% sodium sulfate. The connecting wire cross-section is copper-core cable, with VV-1KV/1*16mm² copper-core cable commonly used domestically.High-Quality Double Iron Foot Marine Zinc Block | Anti-Corrosion Zinc Block ZH-8Implementation Standard: Standard: GB/T4950-2002Zinc-aluminum-cadmium alloy sacrificial anodes are suitable for the cathodic protection of metals against corrosion in ships, mechanical equipment, offshore engineering, and port facilities in seawater and brackish water environments, as well as for pipelines, cables, and other facilities in low-resistivity soil.Jiaozuo Libo Light Alloy Co., Ltd. more>
