The production of graphite tube

The invention discloses a graphite tube with heat exchange function. The graphite tube with heat exchange function comprises the outermost high temperature refractory material, the middle layer of phenolic resin and the innermost layer of graphite are combined The high-temperature refractory material includes molybdenum disulfide, nano-alumina, composite dispersant, nano calcium carbonate and carbon black powder, and the high-temperature refractory material accounts for 21% of the total weight of the graphite pipe with heat exchange function. 25% of the phenolic resin accounts for 25% ~ 26% of the total weight of the graphite tube having the heat exchange function, and the graphite accounts for 48% ~ 56% of the total weight of the graphite tube having the heat exchange function. The present invention provides a graphite tube with heat exchange function, which has the advantages of low preparation cost, good use effect and improved heat exchange efficiency.
