Corrosion and protection in PVC production
Thread Content
Dear colleagues in the marine industry, what types of corrosion occur during PVC production and how can it be prevented? Please share your insights so that we can learn from each other and improve together.
Reply to 1# Knowledge Man: There are quite a few VC synthesis units; once the material enters the converter, if dehydration is not effective, problems can easily occur. It is also necessary to check the pH value of the circulating hot water used for cooling, as it can be quite high. For protection, the equipment must be of high quality, and the personnel on duty need to be more careful; failure to exhaust gas and acid in a timely manner can lead to water getting into the pipes accidentally. Problems can easily arise
