What preservation method should be chosen for highly oxidizing organic acids?
Thread Content
Material properties: Temperature < 70°C, strongly oxidizing organic acids, solid crystalline powder； Let’s discuss: For carbon steel tanks, how should the interior be treated to meet corrosion resistance requirements? 1. The paint (or coating) is relatively simple, but it seems that such paint (or coating) doesn’t exist at all ； There is a paper claiming it exists, but its authenticity is uncertain, and no manufacturers capable of producing it have been found. 2. Lining. Generally, rubber linings are not resistant to strong oxidizing agents, so it definitely won’t work ； Lining with PVC sheets doesn’t seem easy either; how to secure the lining is a problem ； 3. Spraying. It should be possible, but the options for spraying materials are limited, there isn’t much choice, testing is required, and the cost of spraying is too high.
Using fluoropolymers such as PTFE, ETFE, PFA, and ECTFE for corrosion protection can meet the relevant requirements; there are several materials available for selection, covering both temperature resistance and corrosion resistance.
It can be impregnated with graphite and polytetrafluoroethylene
Highly oxidizing organic acids? What specific acid is it? Only by knowing both oneself and the other party can a solution be provided.
