Let’s give praise and support to the achievements made in China’s chemical industry’s technology and equipment. Your participation in discussions is the greatest encouragement**********************【Ten Years of Great Development in Chemical Industry Equipment】A continuously updated compilation post is available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the Office of the State-owned Assets Commission under the State Council officially issued the \"Catalogue of Scientific and Technological Innovation Achievements of Central State-owned Enterprises (2024 Edition)\\", which lists 263 scientific and technological innovation achievements across 7 fields, including electronic components, parts, new materials, and instruments. The \"Graphene-based heavy-duty anti-corrosion coating produced by gas-phase synthesis\" developed by Donghua Engineering Technology Co., Ltd., which is part of the Chinese Chemical Engineering sector, was successfully selected in the field of new materials. Donghua Company’s \"Graphene-based heavy-duty anti-corrosion coating produced by gas-phase synthesis\" utilizes highly consistent gas-phase synthesized graphene to create a unique, dense \"labyrinthine\" physical barrier within the coating, effectively addressing the industry challenges of poor weather resistance in traditional anti-corrosion coatings and unstable performance in conventional graphene-based coating products. This product achieves the highest level of adhesion according to ISO standards, and maintains excellent stability over a wide temperature range of -40°C to 200°C. Compared with traditional epoxy zinc-rich coatings, its single-coat resistance to neutral salt spray testing exceeds 4500 hours. Additionally, it enables a reduction of approximately 1.5 tons of carbon dioxide emissions per ton of product produced. It has been successfully applied in various major engineering projects in Qinghai, Inner Mongolia, and other regions, demonstrating outstanding performance and cost advantages while significantly reducing the corrosion prevention costs throughout the equipment’s lifecycle
