Manufacturer of JXII-40 Nano Carbon Anti Corrosion Galvanized Grounding Device for Petrochemical Composite Anti Corrosion Grounding Electrode

Description :

　　Composite nano anti-corrosion long-lasting grounding electrode, also known as nano anti-corrosion grounding wire, composite anti-corrosion grounding device.

　　The main characteristics of the composite nano anti-corrosion long-lasting grounding electrode are as follows:

　　1. Nano carbon has very strong electrical conductivity, with a resistivity close to that of ordinary metals. As a medium between metal grounding and soil, nano carbon does not affect the diffusion of impulse current.

　　2. Nano carbon has super high temperature resistance and will not detach when subjected to strong current shocks.

　　3. Composite nano anti-corrosion long-term grounding has excellent anti-corrosion performance: for acidic grounding environments, nano carbon grounding bodies use cyclic amines as curing agents, greatly improving the acid resistance of coatings. For alkaline soils, the curing of resins undergoes chemical reactions such as condensation, ring closure, addition, or catalysis, causing irreversible changes in thermosetting resins. Therefore, nano carbon grounding bodies have superior anti-corrosion performance.

　　4. Excellent surface adhesion performance: Epoxy and other materials are used as the base material in the nanocarbon grounding body coating. Due to its molecular structure containing epoxy and ether groups, it has an inherent high degree of adhesion performance, so the nanocarbon will not peel off from the grounding body.

　　Construction technology of composite nano anti-corrosion long-term grounding electrode

　　1. The burial depth of the composite nano anti-corrosion long-term grounding electrode should not be less than 0.8m at the top

　　2. The buried position of the grounding body should not be less than 1.5m away from the building. When encountering buried grounding bodies such as garbage and ash, the soil should be replaced and compacted layer by layer.

　　3. When welding is used for connection, the weld seam at the welding point should be full and have sufficient mechanical strength, without defects such as impurities, undercutting, cracks, virtual welding, pores, etc. After knocking and cleaning the coating at the welding point, apply anti-corrosion coating for anti-corrosion treatment.

　　4. Drill holes at the location of the grounding body according to the design and insert the grounding body. The installation of the grounding body is strictly prohibited from using the tapping installation method. After the grounding body is installed into the installation hole (well), the backfill soil should not contain stones or construction waste, and should be compacted layer by layer during backfilling.

　　5. Fill and compact with soil to ensure close contact between the grounding body and the soil, leaving about 20cm at the upper end for connection with the horizontal grounding wire, and conduct inspection.

　　6. Laying of horizontal grounding wires connecting grounding bodies; Before laying, it should be straightened, and then the grounding wire should be placed in the trench. The horizontal wiring should be connected to the grounding electrode using the designed connection method in sequence. The flat grounding wire should be placed on the side rather than flat. When connecting by welding, the welding slag should be removed after welding, and the surface anti-corrosion coating should be applied to the welded and damaged parts using the process method specified by the factory. Leave sufficient connection length for use at the location where the grounding wire needs to be led out.

　　7. The exposed grounding wire should be painted black, and the paint should be uniform without any omissions, but the terminal clamps and grounding terminals should not be painted.

　　8. After the connection of the composite nano anti-corrosion long-term grounding electrode is completed, the quality supervision department should be promptly requested to conduct a hidden inspection (material, position, welding quality, section specifications, etc.), which should meet the design and construction acceptance requirements. Backfilling can only be carried out after passing the inspection, and the grounding resistance shake test value should be recorded on the hidden inspection record sheet.
