Grounding resistance reduction agent and method for lowering corrosion on grounding body due to grounding resistance reduction agent

Abstract

The invention relates to the technology of grounding for lightening, in particular to a grounding resistance reduction agent and a method for lowering corrosion on a grounding body due to the grounding resistance reduction agent. The method includes preparation of a long-acting anticorrosive agent, preparation of the grounding resistance reduction agent and mixing of the long-acting anticorrosive agent in the grounding resistance reduction agent. The preparation of the long-acting anticorrosive agent includes the steps: firstly, selecting, by weight, 20-30 parts of ammonium carbonate, 50-60 parts of powdered activated carbon and 50-60 parts of bentonite not less than 400 meshes; secondly, feeding the ammonium carbonate, the powdered activated carbon and the bentonite in the proportion into a mixer for blending and mixing, adsorbing the ammonium carbonate with the powdered activated carbon and coating the ammonium carbonate with the bentonite to obtain the long-acting anticorrosive agent. The long-acting anticorrosive agent has two major features of alkalescence and slow release and can keep long-acting anticorrosive effect, thereby being initiative. The grounding resistance reduction agent is remarkable in resistance reduction effect, environment friendly, convenient to use and low in cost.

Description

technical field [0001] The invention relates to lightning protection and grounding technology, in particular to a method for reducing the corrosion of a grounding body by a grounding resistance reducing agent and the grounding resistance reducing agent. Background technique [0002] The grounding system is an important part of the entire lightning protection system. It connects the sky net and the ground grid to improve the leakage rate of the ground grid as a whole. The main technical indicator of the lightning protection grounding system is the grounding resistance, and the smaller the grounding resistance, the better. In order to reduce the grounding resistance, a resistance reducing agent is generally used. The function of the resistance reducing agent is to reduce the grounding resistance of various grounding devices. At present, the drag reducing agent is composed of various components, such as fine graphite, bentonite, curing agent, lubricant, conductive cement, et...

Problems solved by technology

[0003] However, since there are highly conductive salts (silicate, aluminosilicate, etc.) in the resistance reducing agent, they are highly corrosive to the metal grounding body, and the longer the time, the more corrosive to the metal grounding body.

As a result, the conductivity of the metal grounding body is continuously reduced, and the lightning protection effect is reduced

In order to avoid lightning accidents, it is necessary to re-install and re-construct, which consumes a lot of manpower, material resources and financial resources.

The currently used drag-reducing agent only considers the short-term drag-reducing effect after construction, and does not consider its long-term, long-term, and environmental protection.
