On December 9, the carbon-based high-performance materials industry demonstration project of Sinochem Donghua (Anhui) New Materials Co., Ltd. officially commenced construction in the Hefei Xinzhan High-Tech Zone. The project is planned to have an annual production capacity of 200 tons of high-quality graphene and 4,000 tons of graphene-based functional pastes, with a total investment of around 134 million yuan; completion is expected by November 2026. Its main highlight is the establishment of the first graphene production facility in the country that uses a gas-phase synthesis method on an industrial scale, marking a significant breakthrough for China in the large-scale production of high-quality graphene. The project is located in the Xinzhan Chemical Industrial Park, at the intersection of Tongbao Road and Zhucheng West Road in the Xinzhan High-Tech Zone of Hefei, covering an area of 49.43 mu, with a planned construction area of 13,000 square meters. The construction scope mainly includes a facility for the production and purification of high-quality graphene at an annual capacity of 200 tons, a facility for producing graphene-based functional pastes at an annual capacity of 4,000 tons, as well as related supporting projects; the planned construction period is 240 days. It is understood that Zhonghua Donghua (Anhui) New Materials Co., Ltd. is a wholly-owned subsidiary of the listed company Donghua Engineering Technology Co., Ltd.; it was established in December 2024 with a registered capital of 60 million yuan. This project is an important step in its strategy to advance in the field of advanced materials. Currently, the global graphene industry is facing a structural dilemma of overcapacity in low-end products and a shortage in high-end products. Most of the mainstream products in the market rely on graphite as a raw material, which leads to issues such as inconsistent quality and high costs, resulting in a low overall capacity utilization rate. The new continuous production process for graphene powder using gas-phase synthesis adopted in this project is a disruptive technology with independent intellectual property rights. Compared with traditional methods, the graphene produced by this process boasts advantages such as larger sheet size, fewer defects, controllable number of layers, and extremely high consistency; it also holds great potential for controlling production costs on a large scale. In addition, the project will simultaneously establish high-level R&D platforms such as the \"Donghua Technology-USTC Joint Innovation Laboratory\" to foster deep integration of industry, academia, research, and application, thereby providing a continuous source of innovation. To date, Donghua Technology has achieved a series of results in the downstream application areas of graphene. Its **heavy-duty anti-corrosion coating**, developed based on graphene synthesized via gas-phase methods, boasts excellent performance thanks to the creation of a unique, dense \"labyrinthine\" physical barrier within the coating layer. It achieves the highest level of adhesion according to ISO standards, can function in a wide temperature range from -40°C to 200°C, and its resistance to neutral salt spray after a single coating application exceeds 4500 hours – far surpassing that of traditional epoxy-zinc-rich coatings. Additionally, it enables approximately 1.5 tons of carbon dioxide emissions to be reduced per ton of product produced. This product has been included in the “Recommended Catalogue of Scientific and Technological Innovation Achievements of Central State-Owned Enterprises (2024 Edition)”. The high-quality graphene produced by this project can also significantly improve the performance of \"alkene-carbon aluminum alloys\", reducing the deviation in their key performance indicators from 10% to just 0.5%. Its overall performance is superior to that of imported \"lithium-aluminum alloys\" currently used in the aerospace industry, offering a new domestic solution to address the issue of reliance on imported materials in this field.
