The anticorrosion of plate heat exchangers is very important. The anticorrosive methods include corrosion inhibitors and electrochemical maintenance. The following editor will introduce to you what kind of anticorrosion information corrosion inhibitors will bring to plate heat exchangers. 1. The corrosion inhibitor with chromate as a minor component is rarely used in cooling water. The plate heat exchanger chromate ion is a (process) gram preparation. When it is combined with a suitable gram preparation, it can lose Satisfactory and economical erosion prevention results. 2. Chromate-zinc-polyphosphate: The application of polyphosphate is because it has the effect of clean metal surface and has the ability to inhibit corrosion. Polyphosphate can be partially converted into orthophosphate. They can also be used with calcium. Innate colloidal cations, restrain the process. 3. Chromate-zinc-phosphonate: This method is similar to the previous method except that sodium phosphonate is used instead of polyphosphate. Carbamate phosphate can also be used to regulate the pH of polyphosphate. In places where the value is high, the plate heat exchanger carbamate can avoid scales, and even the pH value can control the accumulation of calcium salts. 4. Chromate-Zinc-Hydrolyzed Polyacrylamide: The plate heat exchanger can prevent or restrain the occurrence of scale and dirt due to the diffusion of polyacrylamide hydrolyzed by the cationic copolymer. How about, do you know the above introductions about plate heat exchangers? I hope to bring you some help.
