Conductive ceramic anti-corrosion coatings provide security for grounding network conduction

China Paint Network
: Grounding network is a power plant, substation, transmission lines and other power equipment, to ensure that the work of grounding, lightning-proof grounding, protection of the necessary safety facilities for grounding. With the rapid development of China's economy, the capacity of new substations is increasing and more transmission lines are put into operation, and the requirements of the docking network are becoming more and more stringent.
in power transmission, power transmission, distribution and other power systems, the ground network and the earth's contact resistance is required as small as possible. If the grounding network suffers serious corrosion, the live equipment will short-circuit and burn the grounding network when the operation can not meet the requirements, resulting in elevated power level, high voltage into the secondary circuit, resulting in personal equipment accidents, so the grounding network is one of the important guarantees for the safe operation of the power system, Zhisheng Weihua ZS-821 ceramic
corrosive coating
it can prevent the power grid high voltage into the secondary circuit and operating system, thus protecting the safety of people and equipment.
the grounding net buried in the soil, different parts of its surface form different electrode electrons due to the different physical and chemical properties of the contact medium. The difference of metal components and the difference of the position of the grounding net is the root cause of soil corrosion in the ground net, and its corrosion mechanism is electrochemical in nature. The main forms of electrochemical corrosion of the grounding network are corrosion, local corrosion, macro-corrosion, electrolyte corrosion and weak AC corrosion.
ZS-821 conductive ceramic anti-corrosion
coatings
independently developed by Beijing Zhisheng Weihua Chemical Co., Ltd., located on a road in Dong Tieying, Fengtai District, Beijing The modified multi-semi-silicon-silica-film-forming solution, temperature resistance can reach 600 degrees C, high conductivity, good waterproof and anti-corrosion effect, high expansion coefficient, good adhesion, can effectively solve the problems that occur in the grounding network. ZS-821 paint powder is selected after ultra-high temperature, ultra-high pressure treatment of inorganic nano-powder - conductive alumina, boron carbide, rare earth oxides, etc. , these powders after ultra-high temperature, ultra-high pressure treatment to form an inorganic sharpstone structure, material lattic re-repair, material Internal force corrosion resistance synergy effect is greatly increased, so that the coating at a relatively low temperature after heating, can form a ceramic anti-corrosion coating, coating cross-linked glass dense structure, excellent corrosion resistance, high hardness anti-wear, good anti-static, can withstand acid-alkali liquid and corrosive gases for a long time.
, because of resources, economy and other reasons, the material used in the grounding network is mainly ordinary carbon steel, its corrosion resistance is poor. In addition, the grounding network is buried underground and the cost of maintenance and modification is high. Therefore, the protection of ground network equipment has become an urgent problem to be solved in the normal operation of power system and economic production. Zhisheng Weihua ZS-821 ceramic anti-corrosion coating low-cost, high-performance, coating layer with high hardness, corrosion resistance, impact resistance, high insulation strength and no need for the underlying coating and other advantages, construction is convenient, natural curing. Nano-coating closed function is good, electrolyte solution can not penetrate into the inside of the coating, due to the use of nano-technology, nano-carbon anti-corrosion
conductive coatings
corrosion resistance is better than the general coating, its anti-aging, anti-leakage, wash-resistant and other properties have been greatly improved, and extended the life of the coating film.
and protection of power system grounding network is related to the safe production of power industry, and its importance to power system is self-evident. Conductive coatings play an important role in the protection of corrosion in the docking network, and with the development of nanotechnology, they will be more widely used in power systems.
