Description
Technical field
The present invention relates to a kind of electric resistance reducing grounding material, especially a kind of polymer ground connection mixture.
Background technology
Recent two decades comes, from the appearance of resistance-lowering material to use, indubitable, for the resistance that reduces grounding device has been brought into play larger effect.Along with the development of electric power network technique, friction reducer develops into physics friction reducer from chemical resistance-reducing agent again, and this can't but be a new leap.The friction reducer main component that existing market is sold is that Graphite Powder 99 or salt add charcoal.Because graphite, salt belong to the ionogen of Yi Rong, run off gradually in the underground immersion meeting that is subject to rainwater, underground water, and chlorion in salt also has corrosive nature to ground connector, also will be because electrolytical loss loses the resistance ability of falling gradually, therefore life-time service is difficult to ensure that it falls the effect of resistance.Meanwhile, the grounding for lightening engineering of the high Mountain area to the dangerously steep transport inconvenience of landform, and restricted place, working-yard, the said products cannot meet construction requirement, and expense is very high, weak effect.In order to solve the grounding for lightening engineering of the inconvenient high Mountain area of the dangerously steep transport of various high soil resistivity and landform, and restricted place, working-yard, just almost cannot reach without ground connection mixture the substation that engineering requires, electric railway, mobile base station, electric power send the earth works such as power transmission and transformation.
Summary of the invention
The object of this invention is to provide a kind of polymer ground connection mixture, its stable performance, nontoxic pollution-free, water-retaining capacity is strong, penetrating power good, heatproof characteristic and impact property excellence, is high quality ground connection product ground connector to good protection effect.
Polymer ground connection mixture be by macromolecule water absorbent material, electronic conductive material, ionic conductor etc. under solid-liquid state, through physical change form a kind of translucent gels body, be physical property environmental protection ground connection product.Its resistance mechanism of falling is, under liquid state from ground connector laterally soil ooze out, after within some minutes, solidifying, play a part to increase diffusing electrode contact area, because polymer ground connection mixture itself is a kind of good conductor, it is used between ground connector and soil, on the one hand can with metal ground connector close contact, reduce the contact resistance of ground connector and soil, enough large current flowing cross sections of formation.On the other hand, it can peripherad soil permeability, reduces the resistivity of soil, forms the low resistance region of a variation around ground connector, thereby significantly expand equivalent diameter and the useful length of ground connector, have positive effect to reducing contact resistance and spreading resistance.Can reach work-ing life more than 20 years, stable performance in its life cycle, does not need maintaining, still can have good ionogen performance and water-absorbent, keeps its good physical chemical mechanism.
The polymer ground connection mixture of my company research is physical property environmental protection ground connection mixture, be by macromolecule water absorbent material, electronic conductive material, ionic conductor etc. under solid-liquid state, a kind of translucent gels body forming through physical change.The features such as solidified nature that utilization itself has, adhesive power, shrinkability, chemical stability, after adding special additive, reach and form the very strong electrolysis free ion of conductive capability, in soil, make soil modification reach the object that reduces soil resistivity thereby permeate.

2, having weighed raw material arranges by release sequence (weighing the corresponding starting material packing bag of appropriate to the occasion use package material, in order to avoid clouding confuses).
3, when charging, charging personnel will check load weighted raw material again, and in order not to make any any mistakes, then blowing order is in accordance with regulations put into successively stirrer by raw material and stirred, and in fill process, control the speed of charging well, in order to avoid damage machine.Churning time is controlled at 15 to 20 minutes.B material does not need to stir.
4, sampling inspection at any time, the product through being up to the standards just can packaging and warehousing.
5, expect 0.64 kilogram of/bag of package encapsulation by 1.06 kilograms/bag, packing of product requirement A material, B.Wherein A material is: the mixture of Xylo-Mucine, Repone K, anhydrous sodium sulphate, white cement and zinc sulfate, B material is: sodium polyacrylate.By A material 10 bags, B material 10 bags are put into 25 liters of plastic tanks, build sealing.
6, by good order the plastic tank that the installs product finished product district that is deposited in.And carry out seal approach.
Advantage of the present invention and positively effect are:
1) nontoxic, the free from extraneous odour, corrosion-free, pollution-free of this product; Meet national high-quality soil environmental standard, Environmental Safety, is desirable Green Product.
2) good stability, not soluble and loss.
3) conductive capability is strong, has good electroconductibility.
4) antiseptic property is good, and penetrating power is strong, moisture retention good.
5) volume is little, lightweight, when transport and construction, can not produce dust, very clean; Can not produce the infringement in health to constructing operation personnel yet.Construction only needs to prepare water and stirring tool; Easy construction.
6) convenient transportation, reduces transportation cost greatly, and this product is not limited by or not place, easily takes care of.
Its stable performance of polymer ground connection mixture, nontoxic pollution-free, water-retaining capacity is strong, penetrating power good, heatproof characteristic and impact property excellence, is high quality ground connection product ground connector to good protection effect.
