PRODUCTION METHOD FOR EXFOLIATED GRAPHITE, EQUIPMENT FOR ITS PRODUCTION, EXFOLIATED GRAPHITE AND MEANS OF ITS USE

摘要

The invention describes the production method for exfoliated graphite from expandable graphite, which enters the input section (8) of the heater (1) plane, after contact with the plane heated rapidly with the rate of at least 150°C/s changing its specific weight to value of 30kg/m3 till 10kg/m3. Heater (1) has a temperature ranged from 200°C till 3300°C, whereas expandable graphite and produced exfoliated graphite inside are drifted to the output section (7) and are passed to the cooling chamber (4). Furthermore the invention describes equipment for realization of the mentioned method containing at least a heater (1), temperature controllers (6), storage tank (3), feeder (2), cooling chamber (4), while the heater (1) has an inclined heated plane that can be adjusted to an inclination angle (X) in the range from 5 till 60 degrees. Exfoliated graphite produced according to this invention has extraordinary adsorption properties, and is able to adsorb 20 till 90 times of its own weight, thanks to the vacancies in the graphene layers (14) sized from 0,245nm till 500nm. Exfoliated graphite for example may be used for filtering and cleaning of drinking water and gases, for elimination of crude oil disasters, as well as for thermal, electromagnetic, sound and radiation insulation.
