What should be paid attention to when processing refractory materials with flake graphite?

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

The main methods of graphite purification

1 Flotation methodFlotation method is a commonly used method for purifying minerals. Due to the difficulty of water infiltration on the surface of graphite, it has good floatability and is easy to separate from impurity minerals. In China, flotation method is generally used for beneficiation of graphite.The flotation of graphite raw ore generally uses the positive flotation method first, followed by reverse flotation of the positive flotation concentrate. High grade graphite concentrate can be obtained by using flotation method. The grade of flotation graphite concentrate can usually reach 80% to 90%, and the purity can reach around 98% by using multi-stage grinding.The commonly used collectors for flotation of crystalline graphite are kerosene, diesel, heavy oil, sulfonic acid esters, sulfate esters, phenols, and carboxylic acid esters. The commonly used foaming agents are 2 # oil, 4 # oil, terpineol oil, ether alcohol, and butyl ether oil. The adjusting agents are lime and sodium ca
