Edible alcohol tank anti-corrosion
Thread Content
There is an edible alcohol tank (internal floating roof storage tank). How is the storage tank anti-corrosion? Especially the anti-corrosion of the inner surface of the tank
very simple: 1 Sandblasting reaches Sa 2.5 level or above ； 2. Spray 3 coats of water-based inorganic zinc-rich paint or alcohol-soluble inorganic zinc-rich primer with a dry film thickness of 90-120 microns.
Can't the moderator choose Q235A steel? Isn’t it enough to just do a good job of embalming?
Is 304 okay? Should there be a standard?
It is indeed relatively simple. After surface treatment, the inorganic zinc-rich paint can be 75 microns. If it is too thick, it will easily crack.
Choose 304L stainless steel, as long as there is a small amount of corrosion, it will affect the human body.
