Duoling New Material Technology Co., Ltd. is an enterprise specializing in the development, production and sales of graphene and graphene-related application products. Heilongjiang Duoling branch is located in Mashan District, Jixi City. The total investment of the project is 300 million yuan and it is divided into two phases. Construction. As of the end of 2020, the first phase of the project has been basically completed. The first phase of the project mainly produces graphene oxide, which is the product of graphite powder after chemical oxidation and stripping; the main market for graphene oxide is now 5G terminal equipment heat dissipation In the market, with the advent of the 5G era and Huawei’s first use of graphene heat dissipation film since 2018, it has now pushed the graphene heat dissipation industry to the forefront. The company plans to continue to launch 4 graphene oxide production lines in 2021, and invest in that year In addition, it is expected that the main proj...
