The position and role of carbon industry in the development of the national economy

Compared with large industries such as machinery, automobiles, electronics and electrical engineering, mining and metallurgy, railways, and transportation, the carbon industry is a small industry, but it occupies an important position and plays an important role in the development of the national economy in China. According to China's first five-year plan, 156 large-scale projects were newly built, of which the carbon industry accounted for two projects. For example, the development of the steel industry cannot be separated from carbon materials and products, especially electric furnaces for smelting alloy steel, which must have graphitized electrodes. Electrolytic aluminum production requires the consumption of 400-450kg of carbon anodes for each ton produced. In addition to ordinary civilian industries, carbon fiber composite materials have a wide range of applications in aviation, aerospace, nuclear energy, military and other fields, such as high specific strength, light weight, an

Precautions during the storage process of carbon material raw materials

(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces

The process of industrialization of battery -specific graphene lithium battery industrialization

There is no doubt that the performance of the battery -specific graphene is unquestionable, but is it necessarily suitable for lithium ion batteries? According to my clumsy opinion, graphene is not suitable for lithium ion batteries, please consider the following:1. Cost problemThe cost of using graphene as a conductive agent is much higher than that of ordinary charcoal black. The cost of lithium battery is the key control factor. Without reducing the cost of raw materials, even if the electrical performance of graphene is good, battery manufacturers cannot afford a few tons per ton. 100,000 cost consumption.2. Process problemsThe technical problems brought by the chip structure of battery -specific graphene are mainly preparation of electrode paste. The electrode paste requires good liquidity, decentralization and appropriate viscosity. The dispersing of graphene tablets in the electrode paste is a difficult problem, especially for especially The electrode paste cannot be decentrali
