Embodiment Construction

[0011] According to the content of the above invention, a high water retention bentonite drag reducing agent can be prepared.

[0012] First prepare the activated calcium-based bentonite. Select 200-mesh calcium-based bentonite, put it into a heating furnace, bake it at 300°C for 2 hours, and cool it to room temperature to obtain activated calcium-based bentonite.

[0013] Next, prepare the drag reducing agent. Select 200-mesh activated calcium-based bentonite as the main material of the drag-reducing agent, 120-200-mesh sodium polyacrylate superabsorbent resin and 200-mesh clay as the additive material of the drag-reducing agent, and industrial sodium chloride as the conductive material of the drag-reducing agent , Composite multi-metal general vapor phase corrosion inhibitor as anti-corrosion material of drag reducing agent, according to activated calcium-based bentonite: sodium polyacrylate superabsorbent resin: clay: sodium chloride: composite multi-metal general vapor ph...

Abstract

The invention belongs to a preparation method of a high-water-retaining property bentonite resistance reducing agent. In order to solve the problems that resistance reduction is difficult and a resistance reducing effect cannot last in a high-soil resistivity region, the method comprises the following steps of: preparing activated calcium-base bentonite serving as a main material of the resistance reducing agent by employing a bentonite activation modification technology; preparing the high water-retaining property bentonite resistance reducing agent by using materials such as sodium polyacrylate water absorbent resin, a compound multi-metal general gas-phase corrosion inhibitor, sodium chloride and clay; and carrying out special combined packaging on the resistance reducing agent. The high-water-retaining property bentonite resistance reducing agent prepared by the method can be applied to a lightning protection and electric grounding system and laid around a grounding body, and the grounding resistance of the grounding body is reduced by increasing the equivalent area of the grounding body, reducing contact resistance between the grounding body and surrounding soil and improving and keeping the conductive property of the surrounding soil of the grounding body for a long time.

Description

technical field [0001] The invention belongs to a preparation method of a high water retention bentonite drag reducing agent. Bentonite, superabsorbent resin, preservative, etc. are used as main component materials to prepare a drag reducing agent with good conductivity, high water retention, strong durability and high corrosion resistance. [0002] The highly water-absorbent bentonite drag-reducing agent prepared by the present invention can be used in lightning protection and electrical grounding systems, laying around the grounding body, and reducing the contact resistance between the grounding body and the surrounding soil by increasing the equivalent area of ​​the grounding body And improve and maintain the conductive properties of the soil around the grounding body for a long time to reduce the grounding resistance of the grounding body. Background technique [0003] Resistance reducing agent is an engineering material widely used in lightning protection and electrica...
