NOVELTY - A graphite tube comprises crushed 50-70 pts. wt. graphite powder, 20-25 pts. wt. phenolic resin, and 2-3 pts. wt. graphene. USE - A graphite tube. ADVANTAGE - The graphite tube has improved corrosion resistance, tensile, and compressive mechanical property. DETAILED DESCRIPTION - A graphite tube comprises 50-70 pts. wt. graphite powder, 20-25 pts. wt. phenolic resin, and 2-3 pts. wt. graphene. It is prepared by mixing and crushing graphite powder, phenolic resin, and graphene in an auger machine; controlling current at 8-10 Amps; extruding at 90-100 degrees C, and controlling outlet temperature at 180-200 degrees C; and checking for defects.
