Abstract
The present invention relates to a grounding resistance-reducing agent, particularly to a solid grounding resistance-reducing agent which is produced by a large quantity of pulverized coal ash waste materials generated in fuel electric plants, boilers, etc., and a method for preparing the agent. The solid grounding resistance-reducing agent comprises the components of pulverized coal ash and additives of bentonite, graphite and lime clinker. The components are mixed and stirred during preparation. The present invention realizes integrated treatment for industrial waste materials, reduces pollution, improves environment and changes waste materials into valuable materials. The price of the product per ton is not more than 2000 yuan, and the resistance-reducing effect is obviously better than that of the solid grounding resistance-reducing agent on the present market. Besides, the present invention has the advantages of no toxicity, pollution or corrosion, compact structure, resistivity less than or equal to 0.5 ohm. M, no corrosion for electrodes, corrosion prevention, favorable effect of resistance reduction, long time-effectiveness and stable performance. The grounding resistance-reducing agent prepared from the pulverized coal ash is suitable for the working grounding and the protective grounding of various kinds of electric equipment, the working grounding and the protective grounding of various electronic and telecommunication equipment, the safety grounding and the lightning grounding of microwave towers and various tall buildings, the electrostatic protection grounding of various inflammable explosive places, etc.
Description
(1) technical field
The present invention relates to a kind of grounded resistance reducing agent, solid grounded resistance reducing agent that a large amount of pulverized coal ash waste materials that particularly utilize thermal power plant, boiler etc. to locate to produce are produced and preparation method thereof.
(2) background technology
Ground connection is the key link of eliminating safety devices such as thunder and lightning, static, high-tension electricity, geomagnetic storm, electromagnetic pulse, electromagnetic interference, is one of important measures that guarantee electrical system trouble free service and electric equipment and personal safety.Utilizing grounded resistance reducing agent significantly to reduce earth resistance, is to solve a kind of convenience of problem with grounding and economic method.Used resistance reducing agent has two classes at present.One class is the liquid resistance reducing agent, as urea, formaldehyde and acrylamide etc.Because of the ability and the site operation inconvenience of its cost height, difficult, poisonous, the withstand shock voltage in source and impact, and do not obtain promotion and application.Another kind of is the solid resistance reducing agent, " Franklin-people's livelihood " resistance reducing agent of producing as people's livelihood chemical plant, Chengdu etc., and cost is higher.The pure electron conduction product of the CJ-I type long-lasting grounding resistance reducing agent of Building Material Research ﹠ Design Inst., Hunan Prov.'s exploitation, its room temperature resistivity is 0.72 Ω m, the pH value is 11.9.
As everyone knows, the processing of a large amount of pulverized coal ash waste materials of locating to produce such as thermal power plant, boiler is the problem that people extremely pay close attention to.
(3) summary of the invention
The object of the present invention is to provide a kind of solid grounded resistance reducing agent that a large amount of pulverized coal ash waste materials that thermal power plant, boiler etc. locate to produce produce and preparation method thereof that utilizes.
The component of the said solid grounded resistance reducing agent of the present invention and content by weight thereof are: with pulverized coal ash is 100, and the additive bentonite is 20～40, and graphite is 20～40, and the lime grog is 20～40.
The preparation method of the said solid grounded resistance reducing agent of the present invention is: press above-mentioned component and content thereof with its mixing, stirring.
Efficient compound resistance reducing agent with pulverized coal ash and Additive Production is a kind of grey black look pressed powder of drying, is placed on the following, top of earth electrode and all around and topped upper layer of soil after only needing during use itself and water fully stirred.Because Exposure to Sunlight or arid are rainless, this resistance reducing agent can shrink attached to around the earth electrode in slow dehydration, if after meeting water or rainfall, adhesive then can water absorption and swelling and do not make the resistance reducing agent leaching loss, still can well carbon granules closely be bonded together.In a word, no matter under which type of geography or geological conditions, use, all have favorable conductive, fall resistance, the ability of antioxygen, inhibition, withstand shock voltage and impulse current.
Produce resistance reducing agent with pulverized coal ash the solid industrial waste is carried out integrated treatment, will reduce pollution, improve environment, turn waste into wealth.Resistance reducing agent costs such as " Franklin-people's livelihood " resistance reducing agent are higher, per ton more than 3000 yuan, and product of the present invention is per ton to be no more than 2000 yuan.Use proof through on the spot, its resistance reducing effect obviously is better than solid grounded resistance reducing agent in the market, and earth resistance is below 70% of " Franklin-people's livelihood " resistance reducing agent.Nontoxic, pollution-free, nothing corrosion.This resistance reducing agent structure is tight, stable performance, and resistivity≤0.5 Ω m, not only to the electrode non-corrosiveness and antisepsis is arranged, resistance reducing effect is good, and ageing length, stable performance.The pulverized coal ash grounded resistance reducing agent is adapted to the working earthing and the protective earthing of various electric equipments; the working earthing of various electronics, telecommunication apparatus and protective earthing; the safety ground of microwave tower, various skyscrapers and lightning protection, the anti-static grounding in various inflammable and explosive places etc.
