MG-22 Magnesium Anode | 22kg Magnesium Alloy Sacrificial Anode | GB Standard Production

Jiaozuo Libo Cathodic Protection Materials Co., Ltd. is a professional anti-corrosion materials company engaged in services, production, sales, and comprehensive anti-corrosion design, construction, installation, and technical services. The construction requirements for magnesium alloy sacrificial anodes first involve the burial requirements for the anodes: Prepare the backfill material, mix it in proportion and stir evenly, then fill it into a cotton cloth bag measuring 30 cm in diameter and 1 meter in length. Clean the anode surface as required, then insert it into the center of the prepared backfill material and compact it. The outer layer of the backfill material should be tightly bound and laid flat or vertically, buried at the same depth, 2 to 3 meters away from the protected pipeline. Finally, fill the anode pit with prepared fine soil mixed with salt. When connecting cables to other devices, soldering must be used, except for connections inside the junction box. Before soldering, remove the anti-corrosion insulation layer and clean the surface. After soldering, the soldered points must be treated with insulation and anti-corrosion. The burial depth of the cables should be the same as that of the pipeline. Cables must have sufficient slack, approximately 0.8 meters, not including the protective pipe, to facilitate future maintenance and allow the junction box to be lifted to the ground for testing. The junction box must be firmly buried and waterproofed. Cable colors should be distinguishable, and permanent markers should be placed around the burial location of the anode.

The sacrificial anode kit assembly is designed by our company to meet the high-paced and efficient construction requirements of engineering projects. Based on the traditional single sacrificial anode, it includes matching accessories to make customer construction more convenient, time-saving, and labor-saving.

MG-22 Magnesium Anode | 22kg Magnesium Alloy Sacrificial Anode | GB Standard Production Kit configuration: One sacrificial anode of any specification, one cable, several kilograms of backfill material, one cotton cloth bag, and one plastic woven bag. The composition of the backfill material is: (1) Gypsum powder: 75%, (2) Bentonite: 20%, (3) Anhydrous sodium sulfate: 5%. The sacrificial anode kit assembly is a new concept anode product developed by our company to meet the high-paced and efficient construction requirements of engineering projects. Based on the traditional single sacrificial anode, it includes matching accessories to make customer construction more convenient, time-saving, and better meet customer needs. Kit configuration: One sacrificial anode of any model. One cable conductor: Welded to the sacrificial anode according to the customer's design requirements for length and specifications, and sealed with epoxy resin and dibutyl phthalate in proportion using glass fiber cloth or polyethylene heat-shrink tubing. One package of specialized backfill material. One set of thermite welding agent. One anode cloth bag. Product specifications: Include D-shaped, S-shaped, C-shaped, various special shapes, and extruded embedded anodes. Magnesium alloy sacrificial anode - pre-packaged anode: (including high-potential and low-potential) is the final product of cast anodes and can be directly applied in engineering construction.

MG-22 Magnesium Anode | 22kg Magnesium Alloy Sacrificial Anode | GB Standard Production features high driving voltage, low current efficiency, and high cost. Depending on the shape and electrode potential (open-circuit potential), magnesium anodes can be used in soil or freshwater environments with resistivity ranging from 15 ohm-meters to 150 ohm-meters. They are generally not used in environments with soil resistivity below 10 ohm-meters. The potential of high-potential magnesium anodes is -1.75V CSE, with a driving voltage of 0.85V; the potential of low-potential magnesium anodes is -1.55V CSE, with a driving voltage of 0.7V. The operating temperature can reach 100°C. When the remaining weight of the sacrificial anode is 15% of the initial weight, the anode is considered失效. Therefore, the utilization rate of the anode is generally 85%. Based on the traditional anode, the new concept anode product includes matching accessories to make customer construction more convenient, time-saving, and better meet customer needs.

Backfill material: 75% gypsum, 20% bentonite, 5% sodium sulfate, thoroughly mixed in a mixing tank. Using backfill material can improve the output current efficiency of the anode, retain moisture, reduce the anode's grounding resistance, and ensure uniform corrosion on the anode surface, thereby enhancing anode efficiency. The weight of the backfill material can be adjusted according to customer requirements. The size, weight, and shape of the packaged anode can be customized based on customer needs.
Water heater anodes are mainly used in water heaters, heat exchangers, evaporators, boilers, and other equipment. They soften water quality, remove scale and impurities, and extend the service life of the main unit. With Libo's mature technology, we can produce high-quality magnesium alloy sacrificial anodes for water heaters of various types. The products are divided into two categories: cast (AZ63) and extruded (AZ31), widely used for anti-corrosion in water heaters and boilers.
