Cathodic protection material zinc anode

Zinc alloy sacrifice anode implementation standard: GB/T4950-2002, also known as zinc alloy anode, zinc alloy sacrifice anode

Main uses: Zinc sacrificial anode is suitable for cathodic protection against corrosion of metals in ships, machinery and equipment, Marine engineering and harbor facilities in seawater and fresh seawater medium, as well as pipes, cables and other facilities in low resistivity soil.

Specifications of zinc anodes are divided into: 1. Welded sacrificial anodes for hull (single iron foot) 2. Welded sacrificial anode for hull (double iron foot) 3. Bolted sacrificial anode for hull 4. Sacrifical anodes for common use in ballast tanks sacrifical anodes for use in port and Marine engineering installations 6. Oblong sacrificial anode for seawater cooling water system 7. Disc sacrificial anode for seawater cooling water system 8. Sacrificial anodes for buried pipelines

Brief introduction:

Zinc sacrificial anode is used for soil resistivity less than 20 ohms? Meters of soil or sea water. The electrode potential is -1.10VCSE and the driving voltage is 0.25V. When the temperature is higher than 49℃, intercrystalline corrosion occurs. When the temperature is higher than 54℃, the electrode potential of the zinc anode becomes positive. The polarity of the zinc anode and the steel is reversed, and the cathode is protected, while the steel becomes the anode to be corroded. Therefore, zinc anode is generally used for temperature below 49℃ environment. Zinc anodes must use return packing.

Zinc grounding battery is made up of two or four 1.5 m long zinc bar, separated by insulating pad, then tape tied together, and fills in the conductive filling package material together, applications, the pins are connected to the steel core cable is on both sides of the insulation parts, respectively, to by-pass insulation parts provide a low voltage circuit, usually under the condition of water saturation its resistance is 0.2-0.6 euro, If the resistance of the 2 type does not meet the requirement, 4 type batteries can be used.

The zinc ground battery is made of the same material as the zinc anode. The packing formula is 75% gypsum powder, 20% bentonite, and 5% sodium sulfate. Connection wire section for copper cable, domestic use of vV-1KV /1 *16m㎡ copper cable.
