Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment.

[0014] An improved anti-corrosion and drag-reducing agent for grounding, which is composed of sodium bentonite and graphite, and the weight percentage of each component is: 50-99% of sodium bentonite, 1-50% of graphite, and the main elements in sodium bentonite The weight percentage content is silicon oxide: 40-70%, titanium oxide 0.01-3%, iron oxide 0.5-9%, aluminum oxide 2-20%, calcium oxide 1-7%, potassium oxide 0.1-6%, sodium oxide 1-6%, the fixed carbon content in graphite is 60-90%. Crush and grind the sodium bentonite, mix it with graphite powder and mix thoroughly. It can use dry compress method and wet compress method, generally mainly wet compress method. Prepare a large piece of iron sheet at the construction site, pour the drag reducing agent on it, add water and stir it evenly with a shovel, and then lay the drag reducing agent around the grounding body. The constructi...

Abstract

The invention discloses a long-acting ground antiseptic resistance-reducing agent (modified), which is characterized by the following: consisting of sodium base alta-mud and graphite; making each item of parameter satisfy all index; keeping resistance property stable under multitime industrial frequency and punching electricity action; protecting ground metal; reducing erosion rate from 0.0245 mm per year to 0.0064 mm per year.

Description

technical field [0001] The invention belongs to a physical drag-reducing agent, and relates to an improved grounding anti-corrosion drag-reducing agent which reduces the grounding resistance of electric equipment and prevents corrosion of the grounding body. In other systems using grounding grids. Background technique [0002] In order to reduce the grounding resistance of the power equipment and make the grounding of the power equipment under normal conditions, accidents and lightning strikes, the ground potential of the power equipment installation is fixed within the allowable range to ensure the safety of people and equipment. Since the disclosed CN1062888C long-acting grounding anti-corrosion resistance reducing agent product was put on the market, it has been well received by users because of its excellent resistance reducing performance. But its disadvantage is that although the potassium chloride added in its composition has good electrical conductivity, after being...
