Medium: concentrated nitric acid.
FRP nitric acid storage tanks have good corrosion resistance. 50% or less of nitric acid can be made of FRP materials. Compared with aluminum cans and stainless steel tanks, FRP nitric acid storage tanks have relatively low cost, simple process and long service life. Concentrated nitric acid storage tanks need double-layer composite tanks. If the temperature requirements are high, the lining needs to be made of PVDF material to meet the requirements.
