Graphite is widely used in today's society. Will there be a lack of graphite resources? So this is the basic information of graphite ore and carbon fiber that Xiaobian wants to tell you today

  & nbsp; At present, although only a few countries in the world are engaged in commercial exploitation of flake graphite deposits, the excessive production capacity has caused fierce competition among market suppliers. In terms of output, China is

The world's largest flake graphite producer is also the world's largest flake graphite exporter, which controls the price of the world graphite market.

  scaleGraphite productsMost of the refractory materials are supplied for industrial use, and most of the refractory materials are supplied for consumption by the steel industry. As far as fire-resistant flake graphite is concerned, the purity and scale size of products often determine the market sales price of products. Although China will still be the world's largest producer and exporter of flake graphite in the next few years, other producers in the world are challenging China's status. In particular, several emerging European producers are actively developing resources to compete with China's cheap products with their high-quality products. Chinese flake graphite products are low in price and quality, so some consumers use a mixture of Chinese products and European products to achieve a balance between quality and price.

  & nbsp; Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1 / 4 of that of steel. The tensile strength of carbon fiber resin composites is generally more than 3500MPa, which is 7-9 times that of steel. The tensile elastic modulus is 230-430gpa, which is also higher than that of steel. Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material to its density, can reach more than 2000 MPA / (g / cm3), while the specific strength of A3 steel is only about 59 MPA / (g / cm3), and its specific modulus is also higher than that of steel. In this sense, it indicates the broad application prospect of carbon fiber in engineering. Looking at the excellent properties of a variety of emerging composite materials, many people expect that human beings are entering an era of widespread application of composite materials from the era of steel.

Carbon fiber can be processed into fabric, felt, mat, tape, paper and other materials. In addition to being used as thermal insulation materials, carbon fibers in traditional use are generally not used alone. They are mostly added to resin, metal, ceramics, concrete and other materials as reinforcement materials to form composite materials. Carbon fiber reinforced composites can be used as aircraft structural materials, electromagnetic shielding and de electrifying materials, artificial ligaments and other body substitute materials, as well as for manufacturing rocket shells, motor boats, industrial robots, automobile leaf springs and drive shafts.

  & nbsp; Consumers in western countries believe that the main problems that Chinese flake graphite producers should pay attention to are: damage caused by poor inner packaging; Delay in delivery time; The inspection of each batch of products is not strict; Product book

The quality problems of the body, and so on.

  & nbsp; According to the estimates of western industrial circles, the consumption of flake graphite mineral products for the steel industry in the world will change from a downturn to a steady increase in the next few years, which is consistent with the increase of world steel output. stay

In the refractory industry, it is expected that some high-qualityGraphite productsThere will be a large demand.
