NOVELTY - The method involves selecting then cleaning graphite raw material. Using a blower, the graphite raw material is dried by blowing air at normal temperature. The raw material is put in a drying device and dried with argon gas for one to two hours, and then taken out for crushing and grinding in a period of 2-3 hours. A surface-active agent material is poured into the grinding device set to a temperature of 100-270degrees Celsius, and grinding speed is 50-150 revolutions per minute. The resulting composite materials poured together with paraffin into a continuous screw extruder set to temperature of 80-320degrees Celsius and extrusion pressure of 40-60 mega pascals, obtaining graphite fine powder. Pulse shock wave is applied to the powder. The powder is dispersed by high pressure airflow while exposed to alternating electric field for peeling. USE - Method for preparing graphene by continuous electric explosion cracking graphite, where the graphene is useful in electronic devices such as mobile phones. ADVANTAGE - The method for preparing graphene by continuous electric explosion cracking graphite avoids the introduction of impurities, keeps the excellent performance of graphene, and avoids some impurities mixed into the graphene. The surface structure is not damaged, the maximum range avoids the damage to the chemical reaction to the graphene structure, to obtain the product with high quality, at the same time, while reducing the waste of the resource to reduce the pollution to the environment.
