Gentlemen: Is it feasible to use fiberglass storage tanks for storing hydrochloric acid produced as a by-product of fluorine chemical processes?
Fiberglass-reinforced plastic is resistant to acid and alkali corrosion, and can be used for storing hydrochloric acid; however, it is necessary to prevent the presence of organic substances in the hydrochloric acid, as these substances can cause the adhesives used in fiberglass-reinforced plastic to dissolve, leading to leaks
Analysis indeed shows the presence of organic solvents such as chloroform derivatives in hydrochloric acid, as well as fluoride ions, which can easily cause corrosion of the storage tanks and lead to leaks
Vinyl resin is used, non-woven fabric is employed for the innermost layer, and the acid outlet is placed at the lowest point to prevent the accumulation of organic solvents, allowing it to handle such operating conditions.
No, the fluoride content is too high. Should be worn loosely
We all use fiberglass; the innermost layer requires a special material
If the fluoride content is too high, it is best to avoid fiberglass-reinforced plastic when selecting materials.
It’s mainly the bottom of the tank; the bottom is prone to reacting. The can has no impact
