| titleOfInvention | Process and device for obtaining oxidised graphite |
| abstract | The invention pertains to the technology of carbon-graphite materials, in particular to thenproduction of oxidised graphite used as a component of fireproofing materials, and also to thenproduction of expanded graphite with a high degree of expansion, used in metallurgy, thermalnpower engineering, chemical industry and other industries. n The process of obtaining the oxidised graphite comprises the treatment of powder graphite innan electrolytic solution of strong acids to produce the GIC, hydrolysis, washing and drying thenoxidised graphite. The treatment is conducted in the presence of chemical oxidants at a constantnredox potential 0.55-1.55 V or/and treatment is conducted by anodic oxidation of graphite whilenpassing the electric current through the mixture of graphite and acid placed between anode andncathode at a constant anode potential 1-2 V and in a weight acid-to-graphite ratio of 1-4. As anstrong acid sulphuric or nitric acids are used mainly. n The device for obtaining oxidised graphite comprises reactor with housing having inner cylindricalnsurface. Anode, cathode and the permeable for acid solution diaphragm located betweenncathode and anode are inserted in the housing. Also inserted in the housing are vanes,nwhich are radially fixed on the axial horizontal shaft and have an opportunity of rotation and radialnmoving against the stop to a surface of the anode. Half-ring-shaped situated in the lower partnof the housing between pipes for loading and unloading. The anode is a half-ring whose axis isnshifted against horizontal shaft axis with the gap between anode and diaphragm increasing 1.5-3ntimes from loading to unloading pipe. |
