NOVELTY - Condensing tube manufacturing process of condenser comprises (1) using clear water to remove surface floating dust and water-soluble impurities on the inner wall and outer wall of the condensing tube, and drying, (2) soaking the condensing tube after washed using water into an organic solvent, ultrasonically treating, and then drying, (3) using shot blasting to treat the surface of the condensing tube to increase the roughness of the condensing tube surface, and (4) coating the surface of the condensing tube after shot blasting using a heat-conducting anti-corrosion layer, and after drying, the processing is completed. USE - The method is useful for condensing tube manufacturing process of condenser i.e. copper condensing tube of a condenser of a refrigeration system in automobile system. ADVANTAGE - The condensing tube has better corrosion resistance, at the same time, it also has certain heat conducting performance to improve the heat exchange of the pipe. The polysiloxane resin has good insulating property and good sealing property, and has excellent hydrophobic property, can improve the sealing property and hydrophobicity property of the epoxy resin, and the heat conducting filler coated with fluorinated graphene, it has good thermal conductivity and mechanical performance, it improves not only the thermal conductive resin, but also improves the heat conductivity of the anti-corrosion layer. DETAILED DESCRIPTION - Condensing tube manufacturing process of condenser comprises (1) using clear water to remove surface floating dust and water-soluble impurities on the inner wall and outer wall of the condensing tube, and drying, (2) soaking the condensing tube after washed using water into an organic solvent, ultrasonically treating, and then drying, (3) using shot blasting to treat the surface of the condensing tube to increase the roughness of the condensing tube surface, and (4) coating the surface of the condensing tube after shot blasting using a heat-conducting anti-corrosion layer, and after drying, the processing is completed, in the step (4), the heat-conducting anti-corrosion layer comprises 70-90 pts. wt. aqueous epoxy resin emulsion, 18-26 pts. wt. polysiloxane resin, 22-30 pts. wt. thermally conductive filler, 0.5-1 pts. wt. wetting agent, 0.3-0.8 pts. wt. leveling agent, 0.2-0.6 pts. wt. antifoaming agent and 15-20 pts. wt. curing agent, and the thermally conductive filler is graphene fluoride coated with tungsten boride/aluminum boride.
