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
The present invention relates to a kind of grounded resistance reducing agent, solid grounded resistance reducing agent that a large amount of flyash waste materials that particularly utilize fuel-burning 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 voltage electric, geomagnetic storm, emp, electromagnetic interference, is one of important measures that guarantee electrical system trouble-free service and electric installation and personnel safety.Utilizing grounded resistance reducing agent significantly to reduce stake resistance, is to solve a kind of convenience of problem with grounding and economic method.Used friction reducer has two classes at present.One class is the liquid friction reducer, as urea, formaldehyde and acrylamide etc.Because of its cost height, difficult, poisonous, the withstand shock voltage in source and ballistic ability and site operation inconvenience, and do not obtain promotion and application.Another kind of is the solid friction reducer, " Franklin-people's livelihood " friction reducer of producing as people's livelihood chemical plant, Chengdu etc., and cost is higher.The pure electronic conduction product of the CJ-I type long-lasting grounding friction reducer 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 flyash waste materials of locating to produce such as fuel-burning 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 flyash waste materials that fuel-burning 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 flyash is 100, and the additive wilkinite 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 friction reducer with flyash and Additive Production is a kind of exsiccant grey black look pressed powder, is placed on the following, top of ground connector 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 friction reducer can shrink attached to around the ground connector in slow dehydration, if after meeting water or rainfall, tackiness agent then can water absorption and swelling and do not make the friction reducer leaching loss, still can well carbon granules closely be bonded together.In a word, no matter under which type of geography or geologic condition, use, all have favorable conductive, fall resistance, the ability of antioxygen, inhibition, withstand shock voltage and rush current.
Produce friction reducer with flyash the solid industrial waste is carried out comprehensive treating process, will reduce pollution, improve environment, turn waste into wealth.Friction reducer costs such as " Franklin-people's livelihood " friction reducer 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 stake resistance is below 70% of " Franklin-people's livelihood " friction reducer.Nontoxic, pollution-free, nothing corrosion.This friction reducer structure is tight, stable performance, and resistivity≤0.5 Ω m, counter electrode non-corrosiveness and preservative activity is arranged not only, resistance reducing effect is good, and ageing length, stable performance.The flyash grounded resistance reducing agent is adapted to the working grounding and the protective ground of various electric installations; the working grounding of various electronics, telecommunication apparatus and protective ground; the safety grounds of microwave tower, various Highrise buildingss and grounding for lightening, the anti in various inflammable and explosive places etc.
