What kind of resin is used to make FRP tanks containing nitric acid?
Nitric acid is not stable, light or heat will decompose and release of nitrogen dioxide, nitrogen dioxide produced by decomposition of soluble in nitric acid, so that the appearance of a yellowish brown bottle, should be in the shadows to avoid light preservation, can also be saved in the outer frosted plastic bottle (not recommended), is strictly prohibited contact with the agent.
Concentrated nitric acid is a strong oxidant, in the presence of organic matter, sawdust, etc., can cause combustion. With trace amounts of concentrated nitric acid and oxide can almost except aluminum and chromium in special steel of all metal reacts, aluminum and chromium steel a concentrated nitric acid passivation and alcohol, turpentine oil, coke, organic slag reaction is very intense. Nitric acid is industrially produced mainly by ammonia oxidation. It is used in the manufacture of fertilizers, explosives, nitrates, etc. in organic chemistry, the mixture of concentrated nitric acid and concentrated sulfuric acid is an important nitrating reagent. The chemical formula is HNO3, hydrochloric acid and nitric acid in the volume ratio of 3:1 mixture can be made with corrosive aqua. Nitric acid anhydride is dinitrogen pentoxide (N2O5).
Nitric acid is a strong oxidizing and corrosive strong acid. Chemical formula: HNO3. Melting point: -42 DEG C, boiling point: 78 DEG C, soluble in water, pure nitric acid at room temperature, colorless and transparent.
