Zhong Guo Hua Gong Bao·2025-05-28 02:01Core Viewpoint - Shanghai Petrochemical has successfully developed a carbon-carbon composite material for manufacturing acid-resistant fan impellers, addressing corrosion issues in alkylation units and significantly extending the lifespan of these components [1][2]. Group 1: Technology and Innovation - The new carbon fiber impeller is made from a high-performance carbon-carbon composite material, which is more complex to produce than traditional carbon fiber resin composites [2]. - The lifespan of the carbon fiber impeller is over ten times longer than that of existing materials, providing a cost-effective solution to the corrosion problem faced by alkylation units [2][3]. Group 2: Industry Applications - Shanghai Petrochemical has achieved leading positions in various applications of carbon fiber materials, including oil extraction rods and lightweight components for transportation [3]. - The company is also involved in the construction of the longest onshore wind turbine blades made from carbon fiber composites, set for testing in 2024 [3]. Group 3: Future Developments - A new project for the annual production of 30,000 tons of large tow carbon fiber is underway in Ordos, Inner Mongolia, aimed at establishing Shanghai Petrochemical as a leading carbon fiber company in China [4]. - The company plans to expand its product applications and enhance brand recognition and market share as its carbon fiber production capacity increases [4].
