The relationship between graphene and scales graphite

Graphene is stripped from scales graphite materials, composed of two -dimensional crystals composed of carbon atoms, with a thickness of only one layer. Because graphene has excellent performance in optics, electrical, and mechanics. Is graphite related to graphene? Let me analyze the relationship between scales graphite and graphene with everyone:1. The method of extraction of graphene mass production is not obtained from scales graphite, but from carbon -containing gas such as methane and acetylene. Although the word graphite is used in the name, the production of graphene is not mainly from scales graphite. On the contrary, it is obtained from carbon -containing gas such as methane and acetylene. Even the current research method is extracted from the planting plant tree. Now there is a method for extracting graphene from the tea tree.2, scales graphite contains millions of graphene. Graphene is actually in nature. If the relationship between graphene and scales graphite is mentione

Scales graphite processing

Scale graphite is obtained by mining and processing of the graphite mine. The mined ore categories are different. When processing scales graphite, it is also correctly processed according to the characteristics of graphite ore. So how to operate? Let's make a simple understanding of scales graphite.1. Synthetic graphite crystal crystal mitigation processing method.Cain crystal graphite crystals are very small, so it is also called micro -graphite. Graphite particles are usually embedded in clay and are difficult to separate. Because the original ore product is high (generally carbon -containing), many graphite mines will be crushed directly by the ore adopted by graphite mines and sell them for sale. Graphite products.2. The method of chip graphite in the scales graphite.Crystal graphite has good natural floating nature and is basically used in China. Because the granularity of graphite sheets is one of its most important quality indicators, multi -level grinding is used in the sortin

The advantages and disadvantages of high -carbon graphite purification methods

Floating method is a type of energy consumption and reagent consumption in traditional mineral purification methods. This is the advantage of the floating method to purify graphite. However, the use of floating selection and purifying graphite can only achieve limited graphite taste. For scales graphite, multi -level grinding not only can not completely dissolve the monomer, but it is not conducive to protecting large huge graphite. Therefore It is not economical and unscientific. To obtain high carbon graphite with a carbon content of more than 99%, graphite must be purified by chemical methods.(1) Alkaline purification method. The carbon content purified by alkalinic acid method can reach more than 99%, which has the characteristics of less one -time investment, high product quality, and strong process adaptability.
