NOVELTY - Preparing graphite tube involves mixing 55-65 pts. wt. graphite powder, 15-25 pts. wt. resin and 0.005-0.015 pts. wt. graphene, crushing and mixing in a auger machine without uninterrupting, where the current control of the machine is 20-22 amperes. The mixed material obtained is extruded into an extrusion mold to obtain a semi-finished product, where the extrusion mold comprises a die head and a tube outlet section which are sequentially arranged. The temperature of the mold is controlled at 70-80 degrees C and temperature of the outlet is controlled at 180-200 degrees C. USE - Method for preparing graphite tube (claimed). ADVANTAGE - The method enables to prepare graphite tube, that has corrosion resistance, excellent tensile and compressive mechanical properties, and greatly improved thermal conductivity.
