Abstract

The invention discloses a Teflon heat exchange pipe which comprises an inner pipe and an outer pipe. The outer pipe is arranged on the outer side of the inner pipe, a gap is formed between the inner pipe and the outer pipe, the inner pipe comprises a polytetrafluoroethylene layer and a heat conducting layer, the polytetrafluoroethylene layer comprises, by weight, 95-100 parts of polytetrafluoroethylene resin, 10-15 parts of copper powder, 5-10 parts of graphite, 3-6 parts of molybdenum disulfide and 10-15 parts of aluminum oxide, silver fibers, carbon fibers and glass fibers are woven with one another to form the heat conducting layer, and the heat conducting layer is woven on the polytetrafluoroethylene layer. Owing to the mode, the Teflon heat exchange pipe has the advantages of good heat conducting performance and corrosion resistance and high tensile strength and mechanical strength. Besides, the Teflon heat exchange pipe is particularly applicable to the aspect of the chemical industry.

Description

technical field [0001] The invention relates to Teflon products, in particular to a Teflon heat exchange tube. Background technique [0002] As a heat exchange tube material, Teflon has greatly improved the corrosion resistance of heat exchange equipment and the cleanliness of heat exchange media, so it has been widely used in many fields. However, it also has poor thermal conductivity, low tensile strength, poor wear resistance, and poor industrial processability, which seriously hinder its application in the chemical industry. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a Teflon heat exchange tube of the present invention, which has the characteristics of good thermal conductivity, high tensile strength, good corrosion resistance and high mechanical strength, and is especially suitable for heat exchange in chemical industry Tube. [0004] In order to solve the above technical problems, a technical soluti...
