How to explain the origin of the name "sacrificial anode"?

Answer: According to the electrochemical principle, the magnesium alloy anode material provides cathodic current to the protected object such as a steel structure through electrolytes like soil or water, so that the protected steel structure is cathodized to achieve cathodic protection. As the current keeps flowing, the anode material is continuously consumed. This is the origin of the name "sacrificial anode".

The complete set of magnesium sacrificial anodes of Jiaozuo Libo Light Alloy Co., Ltd. consists of 1 magnesium sacrificial anode ingot, 1 piece of 3 - meter VV - 10㎜ cable, 50kg of backfill material, 1 cotton cloth bag and 1 plastic woven bag. That is, there is 1 magnesium sacrificial anode ingot in the cotton cloth bag, with 1 piece of 3 - meter VV - 10㎜ cable welded to its iron core. The welding part is insulated and covered with a heat - shrinkable tube. 50kg of backfill material is evenly distributed around the magnesium sacrificial anode ingot. The cotton cloth bag is covered with 1 plastic woven bag. Magnesium anodes are suitable for the cathodic protection of steel facilities working in media such as soil, fresh water and seawater.

Specifications and Models   Long - strip Anodes

The sacrificial anode materials in the soil include magnesium and magnesium alloys, zinc and zinc alloys. Aluminum alloy sacrificial anodes are generally not used in the soil. Anode composition, electrochemical performance and application technology. When the resistivity is less than 15 ohms during application, zinc anodes can be selected; when the resistivity is less than 100 ohms, magnesium block anodes can be selected; sacrificial anodes are generally not suitable, and strip magnesium anodes can be used when particularly needed.

For buried cables, the spacing of sacrificial anodes can be determined according to the soil environment. In peat or swamp soil, the anode spacing is 60 - 80m; in black soil or clay, it is 80 - 100m; in sandy soil, it is 120 - 150m. When arranging anodes, it is necessary to consider that the current generated by a group of anodes can meet the protection current required by this section of the cable with a margin.

     A complete set of magnesium sacrificial anodes consists of 1 magnesium sacrificial anode ingot, 1 piece of VV-10㎜2 cable with a length of 3 meters, 50kg of backfill material, 1 cotton cloth bag and 1 plastic woven bag. That is, there is 1 magnesium sacrificial anode ingot in the cotton cloth bag, and a 3 - meter - long VV-10㎜2 cable is welded to its iron core. The welding part is insulated and covered with a heat - shrinkable tube. 50kg of backfill material is evenly distributed around the magnesium sacrificial anode ingot. The cotton cloth bag is covered with 1 plastic woven bag.

The output voltage and current of the base magnesium rod to the steel liner can be adjusted by replacing resistors with different resistances. The adjustment range can be from zero to several hundred ohms, and the magnesium rod can serve in different water quality environments without life attenuation. That is, this anode material can adjust the output voltage and current only by using a magnesium rod in combination with resistors of different resistances, completely replacing the change of the base material of traditional anode rods and achieving the effects of different base anode materials. The resistor is installed in the slot on the top surface of the insulating sleeve, and the insulation from the steel cap is achieved through the sealing sleeve. Moreover, the sealing sleeve and the insulating sleeve are completely sealed by adhesive or hot - melt welding, which can prevent water or water vapor from being introduced along the gap between the two to the top of the magnesium rod and causing corrosion and breakage of the resistor lead solder joints. Magnesium alloy sacrificial anodes are widely used in the anti - corrosion industries of zinc spraying and aluminum spraying in casting, water conservancy, wind power, electric power, transportation, electronics, communication, etc.
