Grounding resistance reducing agent
is composed of a variety of main agents, additives, preservatives and curing agents, scientifically formulated, and strictly It is developed by testing the physical, chemical and electrical properties. 1. Principle of resistance reduction
Xinyongtai resistance reduction agent
is composed of a variety of ingredients, including fine graphite, bentonite, curing agent, lubricant, conductive cement, etc. Resistance reducing agent
is a good conductor. When used between the grounding module and the soil, the resistance reducing agent can be in close contact with the metal grounding body to form a flow surface for large enough current. On the other hand, it can penetrate into the surrounding soil, thereby reducing the resistivity of the surrounding soil and forming a low-resistance area that changes gently around the grounding body.
2. Product usage scope
Xinyongtai resistance reducing agent
has a wide range of uses and is used in various fields of the national economy. It is used in electrical grounding devices in electric power, telecommunications, construction, radio, television, railways, highways, aviation, water transportation, national defense industry, metallurgy and mining, coal, petroleum, chemical industry, textile, medicine and health, culture and education and other industries.
3. Advantages of the product
The resistance reduction effect is obvious, which can reduce the construction workload and reduce the need for grounding. In particular, horizontal grounding can be used to replace vertical grounding that is difficult to construct (in mountainous and rocky areas, etc.) . It is easy to construct, can solve the difficulty of limited construction sites, can save a lot of metal materials, has long-term effectiveness and stability, and has good anti-corrosion performance. Less affected by climate. The overall technical and economic performance is good.
Xinyongtai resistance reducing agent
has long-term effectiveness and stability, and has good anti-corrosion properties. It will not be affected by climate under normal circumstances. The comprehensive advantages are waiting for you. The resistivity of the resistor
If you want to have an obvious resistance-reducing effect, the resistivity value of the selected resistance-reducing agent should be small. When choosing a resistance reducing agent, you should first look at the nominal resistivity of the resistance reducing agent itself. Generally speaking, the smaller the nominal resistivity of the resistance reducing agent, the better. The corrosion rate of the resistor is very small for the steel grounding body, and some resistance reducing agents have anti-corrosion protection for the steel grounding body. Whether the resistance reducing agent has an anti-corrosion effect generally depends on whether the average annual corrosion rate of the steel grounding body is lower than the corrosion rate of the local soil on the steel grounding body. The average annual corrosion rate of the normal soil on the steel grounding body is flat steel For round steel, it is []. If the corrosion rate of the resistance-reducing agent to the steel grounding body is lower than the corrosion rate of the local soil to the steel grounding body, it is considered that the resistance-reducing agent has an anti-corrosion effect on the steel grounding body; otherwise, it is considered to have a corrosive effect. Regarding the stability and long-term effectiveness of the resistor, we hope that the grounding resistance of the grounding device will always be stable below a certain value and do not want it to change frequently. However, the resistance-reducing effect of some resistance-reducing agents will vary with the dryness and humidity of the soil. It changes with the change of water, especially some inorganic resistance reducing agents and ionic resistance reducing agents. Once there is a lack of water, granular crystals will precipitate and lose their conductive properties. Whether the environment is polluted or not, when choosing a resistance reducing agent, you must choose a pollution-free, non-toxic, and safe resistance reducing agent. For the resistance reducing agent, you should look at its components and check whether there is a test report from the environmental protection department. Whether it is convenient to use, whether the price is cheap, the use of resistance reducing agent, especially when used for grounding transmission line poles and towers in mountainous areas, the selected resistance reducing agent should be published and the method is simple. In the end, it is the price that matters. Comprehensive technical and economic considerations must be made. Analysis, it is necessary to meet the performance requirements, and the price must be reasonable and economical
However, the following matters should also be paid attention to during the operation of the resistance reducing agent
Before construction operation, spray must be used Dry the parts to be welded and the investment mold with a torch (or gas blowtorch) to make the resistance reducing agent as dry as possible. Before igniting the construction operation, you must ensure that the investment mold cover is covered and there are no gaps in the closed part of the investment mold. Before operation, it must be ensured that the resistance reducing agent is clean and that there are no welding slag blocks or slag powder left from the previous welding in the investment cavity and mold cavity.
, the operator shall not face the opening of the investment mold during construction. When igniting, once the Xinyongtai resistance reducing agent
is ignited, the operator must immediately leave the investment mold. At least, during the construction operation, before ignition, It must be ensured that the welding point of the welded parts is located in the center of the cavity.
After the reaction of the resistance reducing agent
is completed, no one is allowed to directly contact the investment mold and the welded parts. When the reaction of the resistance reducing agent is completed, the investment mold and the welded parts must be allowed to cool down naturally for seconds before use. The tool pliers are removed from the investment mold.
Therefore, you must pay attention to the above matters during use so that Xinyongtai can better apply the resistance reducing agent
and let the resistance reducing agent play its role.
Guangzhou has all models of drag reducing agents with good performance, and high-quality drag reducing agents are sold directly from manufacturers in large quantities
