Abstract

The invention discloses an anti-corrosion film-coating coating for a heat exchanger copper pipe and a film coating process of the anti-corrosion film-coating coating, and relates to the technical field of heat exchanger film coating. In allusion to the problems that the copper pipe film coating effect is poor and a formed protective film is poor in waterproof and anti-corrosion capacity during existing heat exchanger preparation, the invention proposes the following scheme: the film coating process comprises the steps of S1, cleaning and drying the interior of the heat exchanger copper pipe; S2, preparing an anti-corrosion film coating; S3, coating the interior of the heat exchanger copper pipe with the anti-corrosion film-coating coating in the S2; and S4, putting the oxygen-free copper heat exchanger of the gas heat exchanger in the S3 into a baking furnace to be baked till the anti-corrosion film-coating coating on the inner wall of the copper pipe of the heat exchanger is completely dried so as to complete film coating. An environment-friendly protective film formed by the anti-corrosion film-coating coating has excellent heat-conducting property, super-hydrophobicity and corrosion resistance, the film coating process is simple and easy to operate, efficient heat exchange of the gas heat exchanger can be guaranteed after film coating, and the service life of the gas heat exchanger can be prolonged.

Description

technical field [0001] The invention relates to the technical field of film coating for heat exchangers, in particular to an anti-corrosion coating coating for heat exchanger copper tubes and a coating process thereof. A kind of anti-corrosion film-coating paint for heat exchanger copper tube and its film-coating process Background technique [0002] Heat exchanger (also known as heat exchanger or heat exchange equipment) is a device used to transfer heat from hot fluid to cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to its operation process, it can be divided into three categories: partition type, hybrid type, and regenerative type (or regenerative type); according to the compactness of its surface, it can be divided into two types: compact type and non-compact type. [0003] The heat exchange tubes of the heat exchanger...
