Problems solved by technology

Corrosion is a serious problem that affects and undermines the quality of everyday social life and the endurance of industrial products.
For many traditional products, however, corrosion continues to be a serious destructive problem.
Implementation of such strategies usually produces an inflexible

Relationship Between the Specific Conductivity for Water Solutions and Metal Anti-Corrosion

[0045] The active agent(s) specified as KHDA, HDA and / or their related derivatives embodied in an aqueous solution, show a concentration-dependent ability to alter the normal specific conductivity of water and its dielectric constant to an extent where superficial metal corrosion mediated by water cannot occur.

[0046] Solvent systems of domestic tap water with various concentrations of KHDA easily demonstrate the relationship that exists between specific conductivity (units in μS) of solutions as an indicator of modified electrical status and, observed levels of ferrous metal corrosion. Evidence of metal corrosion can be validated over any time-span ranging from hours to years, depending on the level of analytical sensitivity available for quantifying evidence of metal oxidation.

[0047] As reported in Table 1, an initial domestic tap water solvent demonstrated an initial DO value of 9.3 mg / mL...

Demonstrable Links Between the Consistent Anti-Corrosion Performance of the Composition of the Invention, its Specific Conductivity and Altered Dielectric Properties of Water Using Five Disparate Solute Formulations

[0049] Specific conductivities and dielectric features of water have been found to correlate with metal anti-corrosion set-points in standardized aqueous test solution matrices that permit the predictable performance of the invention.

[0050] A test matrix of different aqueous systems was created that contained different solutes, suspensions and / or dispersions that strategically altered the dielectric (D) property of water, its specific conductivity and its ability to mediate electron flow between reducing and oxidizing agents. In contrast to Example I, in this Example, only highly purified distilled and deionized water was employed. The purpose of this example was to establish a range of aqueous solution standards that provided a series of specific conductivity values fr...

The Altered Conductivity and Dielectric Constant Associated with the Composition of the Invention and its Anti-Corrosion Performance Permits Non-Insulated, Exposed Wires to Conduct Electrical Current Through a Resistor While Submerged in Water

[0053] The invention alters the ordinary electrical performance and conductivity of water, which is a prerequisite to anti-corrosion claims or functions based on oxidation-reduction (redox) theory. This has been validated by the ability of the aqueous invention to maintain operation of an electrical circuit by supplying electric current through non-insulated copper wires to a functioning resistor all of which are submersed under water using the invention.

[0054] The high dielectric constant (D) as well as the ability of the aqueous invention to alter the electrical resistance properties of water have been readily demonstrated by preparing an exhibit specified by the following protocol. A 75-watt light bulb encased in a waterproof cover—only to...

Abstract

Compositions and methods are disclosed for preventing the oxidative corrosion of metal surfaces by exposing a metal surface to an anti-corrosion agent characterized as 2,4-trans, trans-hexadienoic acid (2,4-HDA), its alkali salt identified as potassium sorbate (KHDA), or other derivatives that conserve or embody the 2,4-trans, trans-hexadiene-type moiety present in their molecular structures as an active anti-corrosion agent (ACA), in combination with a material capable of forming a moisture retentive barrier over the metal surface. The compositions and methods of the invention provide a practical, non-toxic way of ensuring anti-corrosion protection for metals, or devices containing exposed metals, stored or operated in water or in the presence of water vapor. Exemplary, non-exhaustive uses of the invention include employing the composition as a lubricant for the surface of a metal or as a pump oil or brake fluid; using the composition as an undercoating for painting, electro-plating or electro-polishing procedures; and providing a protective coating for any metal or metal-containing machine or device, from automotive assembly plant metal press machines to electronic circuit boards.
