Since the second industrial revolution, we humans have entered the age of electricity. The use of electricity runs through all aspects of our lives. But because it has also caused us a lot of trouble, we have been thinking of ways to be safer. Use electricity. Today Xiao Bian gave you an introduction to an item, which is a resistance reducing agent. When it comes to resistance-reducing agents, I think most people will feel unfamiliar, but we must use it in many aspects of our lives, such as mine protection engineering, railway and highway construction, defense and military engineering, and cathodic anti-corrosion projects. Households use electricity to live. Resistance-reducing agents are good electrical conductors and have great uses for our lives. It is especially important for us to be able to accurately and quickly understand the use of resistance- reducing agents . If you have this requirement, then let us work together to understand how to use it.
Resistance reducing agent advantages
The resistance-reducing agent can reduce the construction workload and can reduce the number of grounding bodies. In particular, horizontal grounding bodies can be used instead of vertical grounding bodies that are difficult to construct (in mountain areas and rock areas). The construction is convenient and can solve the difficulty of the construction site. It can save a lot of metal materials, have long-term effect and stability, and have good anti-corrosion performance. Less affected by the climate. Comprehensive technical economy and so on.
Resistance reducing agent use
Resistance reducing agents are widely used in various fields of the national economy. It is used in electrical grounding devices in power, telecommunication, construction, broadcasting, television, railway, highway, aviation, water transport, military defense, metallurgy and mining, coal, petroleum, chemical, textile, medical and health, culture and education industries.
Reducing agent dosage
How to calculate the amount of resistance reducer: 1, drag reducer, water = 1:0.8-1 mix thoroughly and mix into slurry. 2. Wet the grounded holes and trenches that have been dug. 3, with a good drag reducing agent to ground the grounding body tightly wrapped, the thickness of the minimum thickness of the drag reducing agent shall not be less than 7-10cm, with particular attention to the welding point is wrapped tight. After solidification, backfill layer compaction Serve, backfill with fine soil around the grounding body during construction, and prohibit construction waste such as bricks and stones as backfill. When the conditions are poor, backfilled fine soil around the grounding body can be compacted. The backfill of fine soil in the upper layer is not strictly required.
Resistance reducing agent use method
1. Pre-examination inspection items and requirements:
(1) The resistance reducing agent should be the same brand and model product.
(2) The used water is free from pollution, and there is no sediment or other debris in the water.
(3) The size and shape of the ditch and hole are in line with the design requirements. The four walls are relatively flat, and there are no debris in the hole or groove.
(4) The vertical grounding electrode is placed in the center of the hole, and the horizontal grounding body is horizontally centered. The distance from the bottom of the trench is not less than 40 mm and is even (if necessary, it can be fixed with a thin wire).
(5) The ground lead wire has been painted and anti-rust paint according to the design requirements.
2. Modulation resistance reducer
According to the water: a resistance-reducing agent = 0.4, add water in a weight ratio of 1.0: 1.0 and stir until it becomes sticky. The level of grounding water is just enough to wet all the dry powder and can be stirred into a paste. The vertical grounding hole can be filled with water with a leveling resistor and the water level can be taken as a high value.
3. Irrigation, coating, initial inspection
Pour the prepared paste-like resistance-reducing agent gently (to prevent debris and debris from mixing into the resistance-reducing agent) and cover the grounding electrode in the grounding trench and hole until it is completely covered. Less than 40mm, drilled walls are full and should be supplemented when insufficient.
4. Review and backfill
After the initial settling of the resistance-reducing agent, a detailed examination of the resistance-reducing agent shall be carried out. The surface shall be uniform, free of omissions, and free of impurities. The thinnest part of the coating shall be no less than 40mm. After checking, remove the fixed thread and gently backfill the fine soil with no hard objects and branches. The thickness should reach 20mm or more. Then add other soil and compact it. The surface of the backfill soil after compaction should be slightly higher than the surrounding ground level.
5. Ground lead down requirements
The ground deflector should be painted with 2 to 3 epoxy bituminous paints, FVC paints, or other durable paints in the entire section of the surface. The length of the underground section should be no less than 20 mm, and the upper part of the surface should be buried resistance reducer. The length is not shorter than 30mm.
6. Deep well grounding
Deep-well grounding is sometimes necessary. Normally, the well depth is determined by the stratum or groundwater with low resistivity, which is usually tens of meters. It is drilled with a special machine during construction, and the hole diameter is 80-150mm. It is sometimes accompanied by partial blasting, which loosens the surrounding soil and fully fills the resistance-reducing agent to increase the drag reduction effect. The pressure-reduced resistance-reducing agent is injected into the grounding electrode tube, and the resistance-reducing agent surrounds the steel tube from both the inside and the outside and fills the entire drilled hole through the wall hole.
Packaging, storage:
1. This product is double-packed with PVC bags inside and woven bags outside. 25KG per bag, 40 bags per ton.
2. The woven bag is marked with the product name, model, and factory name. When transporting, pay attention to rainproof, moisture-proof and anti-hard material damage packaging.
3. The resistance-reducing agent should be stored in places not exposed to rain and water, and it should be protected from rain and sun exposure during outdoor storage.
4. The shelf life is normally two years. When rainwater soaked in the construction site is abnormal, it should be used within 2 days. The water-reduced anti-erosion agent can be used as backfill for fine soil.
5. The user shall carry out the construction strictly according to the use method to ensure that the resistance-reducing agent achieves the best resistance-reducing effect.
