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.

Abstract

A method for reducing corrosion of a grounding body by a grounding resistance reducing agent and the grounding resistance reducing agent thereof, relating to lightning protection and grounding technology. A method for reducing the corrosion of a grounding body by a grounding resistance reducing agent, comprising the preparation of a long-acting anti-corrosion agent, the preparation of the grounding resistance reducing agent and mixing the long-acting anti-corrosion agent in the grounding resistance reducing agent; the preparation of the long-acting anti-corrosion agent includes: The first step selects ammonium carbonate, powdered activated carbon and bentonite, by weight, ammonium carbonate is 20 to 30 parts, powdered activated carbon is 50 to 60 parts and bentonite is 50 to 60 parts; the order of bentonite is not less than 400 orders; the second The first step is to feed the ammonium carbonate, powdered activated carbon and bentonite into the mixer and stir and mix them. The ammonium carbonate is absorbed by the powdered activated carbon and coated with bentonite to obtain a long-acting anti-corrosion agent. The long-acting anti-corrosion agent has two characteristics of weak alkalinity and slow release, and can maintain long-term anti-corrosion effect, so it is original. The grounding resistance reducing agent of the present invention has a significant resistance-reducing effect, is environmentally friendly, easy 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, etc...
