Research Progress of Antifouling Coating Materials for Heat Exchanger

Heat exchanger is an important equipment of heat and mass transfer in industry, which is widely used in various fields, and its operation efficiency is seriously affected by its surface fouling. Surface antifouling coating technology is an important research direction to solve the problem of heat exchanger surface scaling. In this paper, the effect of surface characteristics (surface energy, contact angle, roughness and corrosion resistance) of surface coating materials on the fouling behavior were reviewed, which provided basis for revealing the differences of fouling behavior of different materials. At the same time, the types and research status of antifouling coating materials were summarized and analyzed to provide theoretical support for the research of anti-scaling coating materials on the surface of heat exchanger.
