New corrosion-resistant and wear-resistant silicon carbide composite materials come out

On June 18th, the “Twelfth Five-Year” National 863 Program “Gradient Silicon Carbide Porous Ceramic/Resin Corrosion-Resistant and Wear-Resistant Composite Pipe Fittings” project held scientific and technological achievements appraisal and product exchange meeting in Beijing. The expert group unanimously agreed that the project passed the technical acceptance, the products are internationally pioneered, and the overall technology has reached the international leading level, which can greatly reduce the operating cost of the desulfurization system of power generation enterprises and reduce pollution emissions, and has a good promotion prospect.

At present, China's energy conservation and emission reduction situation is more severe. Among them, thermal power generation enterprises are the main source of industrial sulfur dioxide waste gas and one of the main culprits of smog formation. At present, the desulfurization pipelines of power generation enterprises in China are widely used in traditional rubber-lined and lining desulfurization pipelines. Due to corrosion, wear and fracture, etc., various losses are caused by more than 10 billion yuan each year, and the desulfurization system is often caused due to unforeseen pipeline damage. Unplanned downtime has greatly affected the efficiency and effectiveness of the entire power generation system.

In order to solve this problem that restricts the development of the environment, under the support of the “12th Five-Year” National 863 Program, Liaoning Zhuoyi New Materials Co., Ltd. relies on the team of scientists from the Research Institute of Materials Special Preparation and Processing of the Institute of Metal Research of the Chinese Academy of Sciences. Based on the original technology of preparation of silicon carbide porous ceramics, after five years of application research, it successfully developed the internationally-first, environmentally friendly and completely independent intellectual property rights of “gradient silicon carbide porous ceramic/resin corrosion-resistant and wear-resistant composite pipe fittings”. The person in charge of Liaoning Zhuoyi New Materials Co., Ltd. introduced that the new corrosion-resistant and wear-resistant composite pipeline has been successfully applied to hundreds of power plants under the five major power companies such as Huadian International and Guodian Power. The data have been recognized by the company as a power generation enterprise. The replacement products of energy saving and emission reduction have broad market prospects and good development space.

According to the State Council and the three ministries and commissions issued the "Full implementation of ultra-low emission and energy-saving renovation of coal-fired power plants" program, by 2020, China will fully implement energy-saving transformation of coal-fired power plants, coal-fired generating units must be installed according to regulations, desulfurization, denitrification and Dust removal and environmental protection facilities significantly reduce pollution emissions. "New silicon carbide porous ceramic products have broad application prospects in many fields such as corrosion-resistant wear-resistant pipes of coal-fired power plant desulfurization systems, which can effectively improve the performance of China's corrosion-resistant and wear-resistant pipes, greatly saving resources and energy, especially for domestic The reduction of operating costs and energy conservation and environmental protection standards for thermal power plants will play a role in promoting this," said Wang Fuhui, chairman of the China Society of Corrosion and Protection and professor of Materials Science at Northeastern University.
