Problems solved by technology

It has not been promoted and applied because of its high cost, difficult source, toxicity, poor ability to withstand impact voltage and impact, and inconvenient on-site construction.
The other type is solid drag-reducing agent, such as the "Franklin-Minsheng" drag-reducing agent produced by Chengdu Minsheng Chemical Factory, etc., the cost is relatively high

Abstract

The present invention relates to low-resistivity earthing agent, and is especially one kind of solid low-resistivity earthing agent with flyash as main material and its preparation process. The solid low-resistivity earthing agent is prepared with flyash as well as additives including bentonite, graphite and hydrated lime and through mixing. Using flyash as main material can reduce environmental pollution and lower cost. The solid low-resistivity earthing agent is superior to available marketable similar product and has resistivity not higher than 0.5 ohm.m, no toxicity, no pollution, no corrosion, compact structure and stable performance. The solid low-resistivity earthing agent may be used widely in work earthing and protecting earthing of various electric apparatus, building, etc.

Description

(1) Technical field [0001] The invention relates to a grounding resistance reducing agent, in particular to a solid grounding resistance reducing agent produced by using a large amount of fly ash waste produced in thermal power plants, boilers and the like and a preparation method thereof. (2) Background technology [0002] Grounding is a key link to eliminate lightning, static electricity, high voltage, geomagnetic storm, electromagnetic pulse, electromagnetic interference and other safety protection devices, and is one of the important measures to ensure the safe operation of electrical systems and the safety of electrical equipment and personal safety. The use of grounding resistance reducing agent can significantly reduce the grounding resistance, which is a convenient and economical method to solve the grounding problem. There are two types of drag reducers currently in use. One is liquid drag reducing agents, such as urea, formaldehyde and acrylamide. Because of its ...
