Problems solved by technology

[0003] Traditional drag reducing agents are all in powder state, and because the fineness requirements are all above 200 mesh, the dust pollution at the production site is serious, and at the same time, dust is generated during transportation and construction, which may easily cause environmental pollution. If there is no corresponding Protective measures and correct construction methods will also cause harm to the human body, and water should be added and stirred on site during construction, which is very complicated and inconvenient

Abstract

This invention discloses a resistance-reducing agent including the following components in weight portions: conductive graphite 45-55, conductive cement: 5-12, sea-foam: 2-10, retarder: 0.1-1.5, moisture agent: 1-3, moisture: 20-35 and others: 5-15. This invention applies a new formula to prepare a grease resistance agent, which can reduce environment pollution and harm to operating persons.

Description

technical field [0001] The invention belongs to the technical field of conductive materials, in particular to a material for reducing the grounding resistance of various grounding devices. Background technique [0002] The resistance reducing agent is a composite material used for grounding devices to wrap around the horizontal and vertical grounding electrodes and has the function of reducing grounding resistance. Its own resistivity is very low, which can reduce the contact resistance between the electrode and the soil, prolong the service life of the grounding device, can withstand the erosion of rainwater and groundwater, can resist high current impact, does not contain toxic components and has good water absorption properties water retention. It is widely used in the grounding devices of substations and distribution stations, power plants and industrial and civil facilities, especially in areas with high soil resistivity. [0003] Traditional drag reducing agents are ...
