On April 25th, the reporter saw in the graphene lubricant production workshop of Huasheng Company that only two workers were filling the product, which basically realized automatic production. "Graphene lubricating oil has passed the physical and chemical index testing and performance testing, and its product performance is at the leading level in China." In the production workshop of Huasheng Graphite Company, Dean Cao Dianxue, Dean of the School of Materials Science and Chemical Engineering, Harbin Engineering University, told reporters that their team was involved in research and development Graphene lubricant products. According to Tsinghua University and Harbin Institute of Technology actual vehicle test results, the use of graphene lubricants saves fuel by 4 to 10%, reduces exhaust emissions by about 80%, and can improve engine power, extend engine life, and extend oil change intervals.
The breakthroughs made by private enterprises in Hegang in the field of graphene application are gratifying. In recent years, Hegang City has taken the graphite industry as a key link and important support for urban transformation, and will build a “graphite new material industrial base” as the main direction of transformation and development, focusing on the three industrial chains of anode materials, graphene, and superhard materials. It took 5 years to make the output value of graphite and related industries exceed 40 billion yuan, and made positive contributions to the creation of a 100 billion-level graphite industrial cluster in the province.
It is understood that Hegang City has proven 1.73 billion tons of graphite ore reserves, ranking first in Asia. The average grade of ore is 10.2%, and the amount of minerals is 170 million tons. It is mainly composed of small scales. It has the advantages of high tap density and high output rate in processing spherical graphite. It is the best choice for the production of high-end anode materials for large power batteries. On the basis of the original graphite industry development plan of 2016-2030, the new Municipal Party Committee of Hegang detailedly issued a three-year special action plan, clarifying the overall idea of building a "one platform, two parks, and three industrial chains", focusing on Promote the high-quality development of the graphite industry. At present, there are 32 graphite enterprises in Hegang City, with a capacity of processing 5 million tons of ore, producing 500,000 tons of fine powder, and 189,000 tons of deep-processed products. In the past two years, 9 projects with a value of more than 10 million yuan have been implemented, and an investment of 1.72 billion yuan has been completed. The output value of graphite has increased from 900 million yuan to 1.8 billion yuan, an increase of 100%, and the tax revenue has increased from 79.5 million yuan to 200 million yuan, an increase of 152%.
Hegang City cooperates with Tsinghua University and Suzhou Sinoma Non-metallic Mining Industry Design and Research Institute to create a public innovation service platform that integrates technology research and development, business incubation, inspection and testing, e-commerce logistics, technology consulting, financial and government services. In 2017, the Hegang Graphite Engineering Research Center was constructed on the platform, and topics such as "development and application of graphite flotation columns" and "high-temperature continuous purification technology of graphite" were carried out. , Diyuan two mineral processing enterprises to promote. Last year, a co-construction agreement was signed with the Powder Research Laboratory of Tsinghua University to jointly build an online inspection and testing platform for graphite products. Currently, platform function development and background database construction are in progress, and trial operation is expected before the end of the year. The National Graphite Product Quality Supervision and Inspection (Hegang, Heilongjiang) scale graphite laboratory and the National Key Laboratory of Graphite Testing have been established to provide technical services to enterprises for free.
Facing the domestic and international competition, Hegang City has found the right direction and focused on the construction of Hegang Graphite New Materials Industrial Park and Luobei Graphite Industrial Park. By extending the three graphite new material industrial chains, a graphite industry gathering area has been established.
In the negative electrode material industry chain, Haida's total investment of 450 million yuan is an annual output of 30,000 tons of high-purity graphite and negative electrode materials. The first phase of the project is expected to start trial in July. After the project is completed and put into operation, it can achieve an annual output value of 1.5 billion . The construction of a 20,000-ton high-purity graphite and anode material project with a total investment of 300 million yuan was started. The first phase of the Guoxintong smart phone and power battery project with an investment of 2 billion yuan is about to enter the equipment commissioning stage. Shenzhen Beiterui Co., Ltd. has also officially entered Hegang. Hegang City will introduce horizontal industrial projects such as positive electrode materials, conductive fluids, and battery separators to close the industrial chain. "Spherical graphite sales revenue was 290 million yuan last year, and 70% of the 20,000-ton-per-year high-purity graphite project under construction has been invested, and it is planned to reach production within the year." Said Chen Rui, head of Aoxing Graphite New Materials Co., Ltd.
On the graphene industry chain, the graphene lubricant products developed by Huasheng Graphite Corporation in 2019 plan to produce 20 tons of graphene and 4,000 tons of graphene lubricants, which can achieve an annual output value of 200 million yuan. The company will introduce graphene conductive paste, graphene heavy anticorrosive material, graphene desalination film and other projects to promote the effective expansion of the industrial chain.
On the superhard material industry chain, Hegang City cooperates with Sanxiang and Changrun to rely on high-purity graphite projects under construction in the region, focusing on the development of diamond powder, diamond composite sheet and other products. Adhere to the concept of circular economy development, actively introduce projects such as high temperature resistant materials such as magnesium carbon bricks and fabricated wall materials to promote the comprehensive utilization of graphite tailings.
