Resistance-reducing agent with self-produced pressure

Abstract

The invention discloses a resistance-reducing agent with self-produced pressure. The resistance-reducing agent mainly comprises the following components in part by weight: 1 to 20 parts of conductive salt, 20 to 60 parts of main agent and 20 to 60 parts of auxiliary agent; the main agent is carbonate or hydrocarbonate, and the auxiliary agent is any one of bisulfate, sulphamic acid and methyldisulfonic acid. The resistance-reducing agent has the advantages that: during production and transportation, dust cannot be produced, the construction procedure can be simplified, the resistance-reducingagent is convenient to use, the cost is reduced, the construction progress can be greatly increased, and the resistance-reducing agent can be supplemented at any time; and because the resistance-reducing agent is not solidified and no residue remains after use, an earth electrode can be repetitively used.

Description

technical field [0001] The invention relates to the technical field of conductive materials, in particular to a drag reducing agent with a main classification number of H01B1 / 06. Background technique [0002] Military command vehicles, communication vehicles, radar vehicles, engineering vehicles, and some special vehicles have strong mobility. Since the vehicles move at any time, the grounding environment they are in changes greatly. The grounding system should adapt to various environments, especially the harsh soil conditions with high soil resistivity; some temporary civil buildings and equipment also need temporary grounding. In an environment with low soil resistivity, it is relatively easy to meet the grounding resistance requirements required by the standard, but it is very difficult to meet the requirements in a sandy and dry environment. In this case, a drag reducing agent needs to be added. [0003] The traditional drag reducing agent has no pressure and is in th...

Problems solved by technology

In the case of emergency grounding, the construction time is long, the resistance reduction is slow, and the remedial measures are inconvenient. If the grounding resistance changes, it must be excavated again; due to the solidification of the traditional resistance reducing agent, the grounding electrode cannot be reused and cannot be applied to the vehicle grounding device.

[0004] The Chinese invention patent with the publication number CN101447242A discloses a technology called "the mixture of tailings and bentonite is selected as the drag-reducing agent for the grounding project of the power grid" as the drag-reducing agent for grounding. , using the tailings and bentonite both contain certain mineral components with valence ions, and bentonite has strong water absorption, long-term water retention, and water retention characteristics, adding some microbial bacteria that can metabolize certain elements of minerals to make the minerals in the minerals Valuable ions are released into the solution to increase the conductive active components in the drag reducing agent and improve the drag reducing performance, but the drag reducing agent has no improvement in increasing its self-pressure

[0005] The Chinese invention patent with publication number CN1988053A discloses a drag-reducing agent, which mainly includes the following components in proportion by weight: 45-55 parts of conductive graphite, 5-12 parts of conductive cement, 2-10 parts of sepiolite 0.1-1.5 parts of retarder, 1-3 parts of humectant, 20-35 parts of water, 5-15 parts of other components. Almost no dust is produced during transportation and construction, which can significantly reduce environmental pollution and physical damage to operators; and it does not need to be mixed with water when used, but its self-pressure is still not increased to adapt to the construction time in emergency grounding. Long, slow drag reduction, and inconvenient remedial measures and other technical problems
