Abstract

The present invention relates to a super-strong water absorbing resin type grounding resistance reducing agent, which is suitable for reducing the grounding resistance of a grounding device of an electric system. The present invention is mainly composed of water-containing super-strong water absorbing resin gelatin, electricity conducting materials (such as strong electrolyte, electricity conducting powder or granules, etc.) or other substances (such as fillers, reinforcing agents, auxiliary agents), etc. The present invention has the advantages of excellent resistance reduction, strong adaptability, long effect, little consumption, low cost, convenient transportation, storage and use, corrosion prevention, good economic benefit of an integrated technique, no toxin or pollution, etc.

Description

Grounded resistance reducing agent
The present invention relates to a kind of grounded resistance reducing agent, belong to a kind of have the macromolecule resin type organic material of super-strong moisture absorbing function and the composite material that inorganic material constitutes, be used to reduce earth resistance.
Earth resistance is the leading indicator of electrical system earthing device, for high resistivity soil layer area, all adopts the method for landfill grounded resistance reducing agent around earth electrode; Existing resistance reducing agent roughly can reduce plain powder of charcoal or metallic particles, inorganic salts and organic salt, the resistance reducing agent that is adopted as Japan Patent JP811467 or easily run off, or the metal earth electrode produced corrosion and influence its effect when long, or material is toxic, and materials are many, the cost height, or needing heating when using at the scene, construction is inconvenient, is difficult to reach the best-of-breed technology economic effect.
The objective of the invention is to overcome the deficiencies in the prior art and a kind of tool long-time stability are provided, be difficult for running off, resistance reducing effect is obvious, the cost of material is low grounded resistance reducing agent.
Grounded resistance reducing agent of the present invention, the water-absorbing resin of 35-99% by weight percentage, the conductive agent of 1-45%, the reinforcing agent of 5-50%, the filler of 5-50% and form less than 10% assistant is characterized in that proportioning is as follows:
Bentonite 5-10%
Cement 5-25%
Graphite 20-45%
Water-absorbing resin 0.4-0.6%
Sodium chloride 0.5-3%
Water 40-60%
Aluminum sulfate 2.5-3%
Polyphosphate 0.5-1%
Zinc powder 0.01-5%
Ammonium chloride 0.05-10%
Water-absorbing resin wherein includes starch based, fiber-like and synthetic resin, especially with polyoxy support class, polyvinyl alcohol, polyacrylate, maleic anhydride class synthetic resin for well, water-absorbing resin mixes the back and forms the aqueous resins gel with water, gel accounts for the part by weight of resistance reducing agent 35-99%; Conductive agent is for improving the conductive material that resistance reducing agent is used, mostly adopt the strong electrolyte material, and electroconductive powder or particle are combined with sodium chloride, aluminum sulfate, ammonium chloride and zinc powder, graphite in this prescription; Reinforcing agent scalable gel time and enhancing colloid intensity, cement in this prescription; Filler can improve resistance reducing agent intensity, is bentonite in this prescription; Assistant then is a rust inhibitor, dispersant, and interfacial agent, polyphosphate has been added in setting expansion agent fast in this prescription; Above proportioning has been formed a typical general curing type prescription of the present invention.
Grounded resistance reducing agent of the present invention has the resistance-reducing performance excellence, and applicability is strong, is difficult for running off, the characteristics of the long timeliness of effect, its consumption also has only the part of conventional resistance reducing agent, and cost is low, transportation, storage and easy to use, anticorrosion, nontoxic, pollution-free, complex art is good in economic efficiency.
A specific embodiment of grounded resistance reducing agent of the present invention is as follows:
Bentonite 7.2%
Cement 7.2%
Graphite 29.2%
Water-absorbing resin 0.5%
Sodium chloride 1.4%
Water 47.5%
Aluminum sulfate 2.9%
Polyphosphate 1.0%
Zinc powder 0.1%
Ammonium chloride 3.0%
