Plate heat exchangers are heat exchange devices prone to scaling; if scaling is severe, the following measures can be taken: First, analyze the type of scaling, and it is advisable to test the scale samples. If it is calcium carbonate scale, physical scale prevention and removal devices such as microwave scale prevention equipment can be installed to prevent the formation of scale; currently, such physical devices are quite effective against calcium carbonate scale. II. If it is calcium sulfate scale, silicon scale, or something similar, then conventional methods generally have little effect. At this point, in addition to using high-pressure water guns for cleaning, it is possible to consider coating or plating the heat exchanger plates with a thin layer of material; this material is very smooth and can significantly reduce the adhesion of substances such as calcium sulfate. By modifying the surface of the material to prevent scaling, it is expected that the amount of scaling can be reduced by 60%.
