According to the National Intellectual Property Administration, Xi 'an Thermal Power Research Institute Co., Ltd. has filed a patent titled' A Method and System for Curing Polyurethane Coating on Hydrogen Turbine,' with publication number CN 120940190 A, filed in August 2025.
The patent abstract reveals that the disclosed embodiments provide a polyurethane coating curing method and system for water turbines. The method comprises: selecting modified polyurethane containing modified nano-ceramic particles as the surface coating layer; dividing the water turbine's flow components into multiple coating zones and conducting surface layer peeling tests to determine each zone's required coating viscosity; mixing and grouping the coating materials from different zones for pre-curing treatments with varying durations to identify viscosity-matched coatings; applying these viscosity-matched coatings through spray application, and utilizing deformable optical channels to guide infrared light emission patterns that align with each zone's surface flatness, thereby irradiating the coatings at target positions for curing treatment.
According to Tianyancha data, Xi 'an Thermal Engineering Research Institute Co., Ltd., established in 2001 and headquartered in Xi' an, is a research and development-focused enterprise with a registered capital of 300 million RMB. Through Tianyancha's big data analysis, the company has invested in 22 enterprises, participated in 5,000 bidding projects, and holds 36 trademark registrations and 5,000 patent records. Additionally, it possesses 40 administrative licenses.
