New corrosion-resistant wear-resistant silicon carbide composites come ou

Technology Daily (Reporter Hao Xiaoming) Recently, a new type of silicon carbide desulfurization pipeline product that can effectively reduce the operating cost and pollution emissions of power generation companies' desulfurization systems has been recognized by experts

At present, China's power generation enterprises desulfurization pipeline widely used is the traditional lined rubber and lining porcelain desulfurization pipeline, due to corrosion, wear, fracture and other reasons, causing various losses every year in more than 10 billion yuan. In order to solve this difficult problem that restricts the development of the environment, Liaoning Zhuoyi New Materials Co., Ltd., relying on the team of scientists of the “Special Material Preparation and Processing” Research Institute of the Institute of Metals, Chinese Academy of Sciences, on the basis of the original technology for the preparation of high-performance silicon carbide porous ceramics, lasted for 5 years. In the year of applied research, the company successfully developed the “Gradient Silicon Carbide Porous Porous Ceramic/Resin Corrosion and Wear-Resistant Composite Pipe Fittings”, which is the first in the world and has completely independent intellectual property rights

Professor Wang Fuhui, director of the China Society for Corrosion and Protection and professor at Northeastern University, said that gradient-grade silicon carbide porous ceramics are a type of porous ceramic material with three-dimensional connected network structure. They are different single metals, foamed silicon carbide and special polymer resin materials. Materials, using a certain combination of methods to organically integrate into a unique structure, the overall reinforcement and particle reinforcement combined with a new composite wear-resistant anti-corrosion pipeline. This new type of pipe can effectively utilize the strong corrosion resistance, high wear resistance of the silicon carbide ceramics, and the excellent corrosion resistance of the polymer resin, and the characteristics of the toughness and temperature resistance of the metal material, effectively solving the problem that the traditional single material is resistant. The problems of erosion, wear, etc. cannot be balanced. At present, the new corrosion-resistant and wear-resistant composite pipeline has been successfully applied to hundreds of power plants under the umbrella of five major power companies, such as Huadian International and Guodian Power. As a replacement product for energy-saving and emission reduction of power generation enterprises, it shows excellent economic and social benefits
