Definitions
- the present invention relates to a corrosion inhibitor for bathing water which contains chlorides and sulfates, in particular sodium chloride and magnesium sulfate, and which reduces the corrosion effect of such bathing water on metallic materials, such as in particular steels (structural steel) and brass.
- chlorides cannot always be avoided as a component of bathing water.
- the invention therefore relates to a corrosion inhibitor for chloride and sulfate-containing bathing water, which can be prepared by mixing
- Phosphoric acid is generally used in its concentrated form, i.e. 85%.
- the amount of phosphoric acid is preferably between 12 and 25% by weight, in particular between 14 and 16% by weight.
- the alkali metal hydroxide is preferably sodium or potassium hydroxide. It can be used in solid form or in the form of aqueous solutions.
- the amount of alkali metal hydroxide is preferably between 12 and 18% by weight, in particular between 14 and 16% by weight.
- the amount of zinc chloride is preferably between 1 and 4% by weight, in particular between 1, 5 and 2.5% by weight. ,. ...;. X
- Aminotrimethylenephosphonic acid is generally used in the form of an aqueous solution which contains about 50% by weight.
- the amount of aminotrimethylenephosphonic acid is preferably between 0.1 and 1 * % by weight, in particular between 0.15 and 0.4% by weight.
- Another object of the invention is the use of the corrosion inhibitor according to the invention in amounts of 0.01 to 0.5 wt .-%, based on the weight of the bath water, for inhibiting the corrosion of steel and brass, which are in contact with chloride and sulfate Bathing water.
- An important technical advantage of the corrosion inhibitor according to the invention is its effectiveness in the almost neutral pH range between 7 and 8, in particular 7.2 to 7.6.
- the pH of swimming pool water is usually between 7.2 and 7.6. So far, experts have searched in vain for a corrosion inhibitor that provides adequate corrosion protection at pH values between 7.2 and 7.6.
- the conventional inhibitors usually work at pH values greater than 9. Because of this fact, corrosion inhibitors on a chemical basis for checking corrosion at pH values between 7 and 8 have hitherto been used only to a limited extent.
- the advantage of this inhibition compared to the prior art is that very small amounts of corrosion inhibitor already lead to an effective minimization of the corrosion phenomena on steel, mild steel and brass. Due to the very small amounts used, corrosion protection can be achieved with very little financial means.
- a bath water was treated with 0.05% by weight of an inhibitor consisting of 67.18% by weight of water, 15.20% by weight of 85% phosphoric acid, 15.29% by weight of 45% potassium hydroxide solution, 2 , 04% by weight zinc chloride and 0.23% by weight.
- an inhibitor consisting of 67.18% by weight of water, 15.20% by weight of 85% phosphoric acid, 15.29% by weight of 45% potassium hydroxide solution, 2 , 04% by weight zinc chloride and 0.23% by weight.
