The heat exchanger tube bundle requires an anti-corrosion coating that is heat-resistant, has high thermal conductivity, and can cure at room temperature
Thread Content
To develop anti-corrosion coatings for heat exchanger tubes, it is necessary to use coatings that cure at room temperature, are heat-resistant, and have high thermal conductivity. The epoxy-amine coatings currently in use require curing at 120°C and involve multiple coating layers, making them unsuitable for use in large-scale installations. Developing coatings that can cure at room temperature and are easy to apply remains an issue that has not been fully resolved to date. The key is to find the optimal balance among the coating’s corrosion resistance, heat transfer properties, and workability.
Yes, the anti-corrosion coating for the heat exchanger tubes developed needs to have heat resistance, good thermal conductivity, and the ability to cure at room temperature. Epoxy amino coatings are currently the most commonly used, but these coatings require curing at a high temperature of 120°C and multiple applications, which makes them unsuitable for large-scale equipment. Therefore, how to develop a coating that can cure at room temperature, is easy to apply, and simultaneously achieves an optimal balance among corrosion resistance, heat transfer performance, and workability remains an unsolved problem to date. .
