The emerging polyether ether ketone (PEEK) films were evaluated as future heat exchanger materials in seawater thermal desalination processes. Fouling resistance curves were measured in a pilot plant for pure PEEK films, talcum‐filled PEEK films, and stainless‐steel films with artificial seawater, showing that pure PEEK films have the advantage of weaker forces of adhesion or cohesion between the scaling materials and the film surface. Increasing the flow rate from 18 to 24 L min⁻¹ results in decreases of both the fouling rate and the asymptotic values. This was attributed to the lower polarity of 10.4 %, the lower arithmetic average roughness of 0.06 μm, and the homogeneous topography of the PEEK film. This polymer film is adaptable to in situ cleaning in thermal seawater desalination processes.

海水淡化中的聚合物膜传热表面：污垢层的形成和技术

新兴的聚醚醚酮（PEEK）薄膜被评估为海水热脱盐工艺中未来的热交换器材料。在中试工厂中对纯PEEK薄膜，滑石填充的PEEK薄膜和带有人造海水的不锈钢薄膜的抗污性曲线进行了测量，结果表明，纯PEEK薄膜的优点是结垢材料与底漆之间的附着力或内聚力较小。薄膜表面。将流量从18 L min ^-1增加到结垢率和渐近值均降低。这归因于较低的极性10.4％，较低的算术平均粗糙度0.06μm和PEEK膜的均匀形貌。该聚合物膜适用于热海水淡化工艺中的原位清洁。
