Graphite powder preparation process and use

Graphite powder preparation process and uses What are the research processes and uses of graphite powder surface preparation? Graphite powder is one of the types of graphite powder. The raw material of ultrafine graphite powder is natural flake graphite, which is pulverized by jet mill or ultrafine flake machine. The particle size of ultrafine graphite powder is 6~10μm, which is ultrafine Graphite powder.. The preparation and research process of graphite powder is: natural flake graphite and raw coke are compressed and the air enters the crushing chamber without passing through the feeder ejector. The nozzles are distributed on the periphery of the crushing chamber to spray ultra-high-speed airflow into the crushing chamber. As a result, the coke powder interacts with each other and develops collision and friction at a high speed to form fine powder. The air flow with fine powder is discharged from the outlet pipe into the classification chamber. The coarser particles can be separated and cultivated, and then crushed again through the return pipe, and the remaining fine powder is used Cyclone separator and bag collector grading information collection. Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make high-purity or carbon fiber, the added value is high. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. The conductors that heat and melt the charge can be classified into ordinary power, high power and ultra-high power according to their quality indicators. Graphite electrodes mainly include four types of ordinary power graphite electrodes, anti-oxidation coating graphite electrodes, high-power graphite electrodes and ultra-high-power graphite electrodes.
