Graphitization process<\/b><\/strong><\/a><\/p>\n At high temperatures of 2000-3000\u2103, the amorphous carbon in the carbonized green body is rearranged into hexagonal lattice graphite crystals. This significantly enhances\u00a0key properties such as electrical conductivity, lubricity, and high-temperature resistance. \u200b<\/p>\n

Post-processing<\/h3>\n Crushing and Grinding<\/b><\/strong><\/p>\n Graphite blocks were crushed by using equipment such as ball mills, vibration mills and jet mills to obtain different particle sizes.<\/p>\n
<\/p>\n
Grading and Packaging<\/b><\/strong><\/p>\n Classify the crushed graphite powder and produce\u00a0different products\u00a0according to the particle size specifications. After passing the quality inspection, it is packed in plastic woven bags, paper bags or sealed drums. It ensures\u00a0that transportation and storage are not contaminated.<\/p>\n
New graphite powder preparation technology<\/h2>\nPreparation of Nano-Graphite Powder<\/h3>\n 5.1.1 Chemical Vapor Deposition<\/b><\/strong><\/p>\n The CVD method uses methane and other gaseous carbon sources to form nano-graphite layers. This process requires the decomposition and deposition of the carbon source on the substrate at 800-1200\u2103 and under the action of a catalyst. The product has the high purity, which is suitable for the high-end electronic field, but the efficiency is low.<\/p>\n

5.1.2 Ultrasound-assisted liquid-phase exfoliation method<\/b><\/strong><\/p>\n This is to disperse natural graphite in solvents such as NMP, break the interlayer forces of graphite, and peel off to obtain nano-powder. The process is simple and features low energy consumption, allowing for mass production, suitable for scenarios with low uniformity requirements.<\/p>\n

Manufacturing of Composite Graphite Powder<\/h3>\nComposite process with metals and polymers<\/h4>\n Metal composite<\/b><\/strong><\/p>\n Powder metallurgy mixed sintering, then it has the lubrication and metal strength, which is used for self-lubricating components.<\/p>\n
<\/p>\n
Polymer compounding<\/b><\/strong><\/p>\n When graphite powder is compounded with polymers, the commonly used methods include solution blending and melt blending. It has electrical and thermal conductivity, which is used in industrial products that conduct electricity and heat.<\/p>\n
Quality Control and Environmental Protection Measures in the Manufacturing Process<\/h2>\n Quality Inspection<\/b><\/strong><\/p>\n The final finished product needs to be tested for properties such as particle size, purity and electrical conductivity. And appearance defects should be analyzed with instruments to ensure that the finished product meets the standards.<\/p>\n
<\/p>\n
Environmental Protection Treatment<\/b><\/strong><\/p>\n After manufacturing graphite powder, you need to carry out environmental protection treatment to prevent air pollution, water pollution, etc. For example, you can neutralize, settle and filter the wastewater to purify it. And remove the dust and harmful gases by using bag filters, electrostatic precipitators and scrubbers to reduce environmental impact.<\/p>\n
Conclusion<\/h2>\n The production of graphite powder requires the selection of processes based on the characteristics of raw materials. Natural graphite focuses on purification,\u00a0artificial graphite emphasizes graphitization, and new technologies promote nanoscale and composite processes.\u00a0Meanwhile, you need to take into account both quality control and environmental protection requirements.<\/p>","protected":false},"excerpt":{"rendered":"
