Industry Background: Copper Corrosion Protection Challenges in the Energy Transition
As the global energy transition accelerates, copper has become an indispensable core material in the new energy industry, owing to its superior electrical conductivity, thermal conductivity, and corrosion resistance. 2025 data shows that copper demand from emerging sectors such as new energy and grid upgrades has reached 56% of total consumption, far exceeding the 18% from traditional real estate. Among these, the photovoltaic, wind power, and new energy vehicle industries together consume 5.669 million tonnes of copper, accounting for 20.73% of global refined copper consumption.
However, the widespread application of copper in the energy sector also presents severe corrosion challenges. In critical scenarios such as power plant heat exchange systems, power transmission and distribution equipment, and new energy installations, copper materials are exposed to complex corrosive environments. Statistics show that condenser corrosion leakage accounts for approximately 50% of all incidents in thermal power plants, and roughly 50% of generator failures are attributed to cooling water system corrosion. In the new energy vehicle sector, corrosion of high-voltage wiring harnesses, battery busbars, and other components directly affects vehicle safety and service life.
Traditional copper corrosion inhibitors such as benzotriazole (BTA) and tolyltriazole (TTA) suffer from poor water solubility and inconvenient handling, making it difficult to meet the increasingly stringent protection requirements of the energy sector. Additionally, with tightening environmental regulations, the ecological risks of traditional inhibitors have drawn growing concern. The EU REACH regulation has placed BTA and certain derivatives on the SVHC candidate list, requiring progressive use restrictions in sensitive applications.
Core Technical Advantages: Molecular Innovation Driving a Protection Revolution
Through advanced molecular design and chemical modification, Tianjin Hi-Perferal Advanced Materials Co., Ltd. has introduced the Vanconol® series copper corrosion inhibitors, delivering a revolutionary solution for copper protection in the energy sector.
Vanconol® CPI-42: A Breakthrough in Diethanolamine-Modified BTA
Vanconol® CPI-42 is a next-generation high-efficiency water-soluble metal corrosion inhibitor developed by modifying the classic copper corrosion inhibitor benzotriazole (BTA) with diethanolamine. Its core advantages include:
1. **Water Solubility: Enables direct dosing and automated precision feeding, eliminating the need for organic solvents or strong alkalis required to dissolve conventional BTA
2. High Corrosion Inhibition Efficiency: Forms a dense and robust adsorption protective film on metal surfaces, with corrosion inhibition efficiency over 30% higher than conventional BTA
3. Multi-Metal Protection: Suitable for copper and copper alloys, steel, galvanized steel, and other metal materials
4. Broad pH Applicability: Stable performance across a pH range of 6.0–10.0
5. Environmental Safety: Free from EU REACH Substances of Very High Concern, with excellent environmental compatibility
Vanconol® CPI-AP: Innovative Application of Piperazine Active Groups
Vanconol® CPI-AP is a next-generation high-efficiency, multifunctional metal corrosion inhibitor based on chemical modification of the traditional copper inhibitor tolyltriazole (TTA). By introducing piperazine active groups, this product builds on TTA’s excellent copper corrosion inhibition performance while achieving three major breakthroughs:
1. Significantly Enhanced Water Solubility: Miscible with water in any proportion, compatible with automated dosing systems
2. Wider pH Applicability: Stable performance across a pH range of 5.5–10, with superior corrosion inhibition to conventional BTA under low-pH conditions
3. Extended Protection Scope: Highly effective not only for copper and copper alloys but also for various non-ferrous and ferrous metals
Vanconol® CPI-MI: Imidazoline-Modified Broad-Spectrum Protection
Vanconol® CPI-MI is an imidazoline-modified benzotriazole corrosion inhibitor. By incorporating imidazoline active groups, it achieves two core improvements:
1. Substantially Improved Water Solubility: Overcomes the limited water solubility of conventional BTA (approximately 25 g/L at 20°C), enabling direct dosing
2. Extended Protection Scope: Highly effective for copper and copper alloys, while also delivering excellent corrosion inhibition for steel, galvanized steel, and other ferrous metals—suitable for multi-metal systems
Application Scenarios: Full-Chain Coverage of the Energy Industry
The Vanconol® series copper corrosion inhibitors provide tailored protection solutions for three core application scenarios in the energy sector:
Power Plant Heat Exchange Systems: Ensuring Stable Unit Operation
In power plant heat exchange systems, condenser copper tubes, generator cooling water systems, and other components are in prolonged contact with water containing high salt content, impurities, and dissolved oxygen, making them susceptible to corrosion. The Vanconol® series inhibitors effectively suppress under-deposit corrosion, electrochemical corrosion, and biological corrosion, extending equipment service life.
In a field application at a thermal power plant, the use of Vanconol® CPI-42 reduced the corrosion rate of condenser copper tubes from 0.023 mm/a to 0.007 mm/a, extended the maintenance cycle from 6 months to 18 months, and saved approximately RMB 2 million annually in maintenance costs.
Power Transmission, Distribution, and Electrical Equipment: Enhancing Grid Reliability
Copper components in power transmission and distribution equipment face multiple challenges including atmospheric corrosion, electrochemical corrosion, and stress corrosion. The Vanconol® series inhibitors form a dense protective film on copper surfaces, effectively resisting attack from corrosive media such as H₂S and Cl⁻, ensuring safe and stable grid operation.
In a coastal substation application, the use of Vanconol® CPI-AP reduced the corrosion rate of copper busbars by 75% and extended equipment service life by more than twofold, significantly lowering grid operation and maintenance costs.
New Energy Sector: Supporting Green Energy Development
