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 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.

Several physical and chemical indicators that need to be understood when selecting graphite materials

Graphite is an allotrope of elemental carbon, where each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb like pattern with multiple hexagons) that are covalently bonded to form covalent molecules. Due to its excellent properties, graphite is used to make many materials. Below are several physical and chemical indicators that need to be understood when selecting graphite materials:1. Average particle diameter of the materialThe average particle diameter of a material directly affects its discharge condition. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the better the surface quality. For forging and die-casting molds with low surface and precision requirements, it is usually recommended to use materials with coarser particles; For electronic molds with high surface and precision requirements, it is recommended to use an average particle size of 4 μ Mater
