Description

1. Technical field [0001] The invention relates to a grounding conductive material, which is used for reducing the grounding resistance of various grounding devices. 2. Background technology [0002] In order to protect the safe operation of buildings and electrical and electronic equipment, lightning protection, anti-static and anti-interference grounding resistance reduction devices are generally installed. Before the 1980s, metal materials and chemical resistance reduction methods were mainly used as grounding resistance reduction methods, which not only cost high but also have unstable chemical properties, causing certain pollution to the environment. After the 1990s, electrode graphite with stable chemical properties and less pollution was mainly used as a physical resistance reducing agent for non-metallic conductive materials. At present, domestic manufacturers mainly use electrode graphite as a non-metallic conductive material, mix it with alkaline gel to form a res...

AI Technical Summary

Problems solved by technology

Before the 1980s, metal materials and chemical resistance reduction methods were mainly used as grounding resistance reduction methods, which not only cost high but also have unstable chemical properties, and have certain pollution to the environment.

Its advantage is that the electrode graphite has high carbon content, stable chemical properties, and strong electrical conductivity, but its obvious shortcomings: First, the cost of electrode graphite is too high, the price of a ton of electrodes is tens of thousands of yuan, and the price of electrode graphite fragments is also low. About 4,000 yuan per ton; second, the discharge of pollutants is relatively large in the process of producing electrode graphite; third, the cost of processing electrode graphite into graphite powder is relatively high, and dust is also generated to pollute the environment

Therefore, the resistance-reducing agent and the resistance-reducing module processed and produced with electrode graphite as the main component have high cost and great pollution to the environment, and the product has certain limitations in the application process.
