What materials does aluminum sulfate react with?
Thread Content
The project I’m working on now requires aluminum sulfate solution; I’ve never used it before, and my searches on Baidu didn’t help much. Does aluminum sulfate hydrolyze to produce sulfuric acid? So will my containers corrode if they are made of stainless steel or aluminum? The pump for pumping the aluminum sulfate solution has a PTFE diaphragm and a PVDF pump head, with UPVC pipes – is there any problem with that? Can the rubber used for gaskets in common UPVC valves be used? Can EPDM be used?
I’m not quite sure what you mean, but I can tell you that using aluminum sulfate in fiberglass tanks is definitely no problem – we have handled many such cases. If you need any assistance, feel free to contact us at any time. :)
The hydrolysis of aluminum sulfate produces sulfuric acid, which reacts with metals to form ferrous sulfate, thereby causing corrosion on the metal surface. At this point, using 18-8 stainless steel will also lead to corrosion. It is recommended to use fiberglass-reinforced plastic material for the equipment when the temperature does not exceed 80 degrees. Such as epoxy fiberglass reinforced plastic, etc.
Hello, what is being applied as a coating inside your aluminum sulfate storage tank?
Substrate treatment: apply one coat of metal primer 8231A, then attach a layer of photocurable sheeting, and apply one coat of surface sealing coating
