Description

    DISCUSSION OF PRIOR ART AND BACKGROUND OF THE INVENTION
  • The invention which is the subject of this patent application is directed to a process for protection of the exterior of a metallic product from corrosion, such as oxidation resulting in rusting of the metallic surface or exterior. [0001]
  • The general area of focus is directed to means to cover the exterior of the product from oxidation or other chemical reactions that cause the surface to be corroded. Another focus of the subject invention is to remove rust, or other corrosive by-products from the exterior surface of a metal. [0002]
  • In short the subject process herein described is adapted to both protect and shield a metallic surface from corrosive activity, as well as clean and remove from the metal surface already existing corrosive substances. The latter cleanser process may be utilized to precede painting on the metallic surface as an additional protective layer; [0003]
  • In the perspective and context of the subject invention, as is known, metallic surfaces are invariably subject to and susceptible to corrosive processes, in which the metallic surfaces reacts chemically with the surrounding elements, most usually oxygen. These reactions result in differing chemical reactions and thus varying chemical processes, generally referred to as corrosive reactions leaving a layer of corrosive material on the outer surface of the metal. One of the most frequently encountered corrosive processes is oxidation of iron resulting in a layer of iron oxide, commonly referred to as rust. [0004]
  • These described corrosive processes leave the metallic surface susceptible to deterioration and if left long enough causes deeper penetration of the corrosion into the metallic object, causing an eventual weakening and deterioration of the entire metallic object. This may adversely affect other interconnected systems or structures. For example, if one portion of an iron-based bridge structure become substantially weakened the entire bridge integrity and strength is adversely affected. Thus, rust protection and rust proofing of all integrated metallic sub-structures of a bridge is one of the most important aspects of maintaining the bridge. [0005]
  • There have been innumerable processes and products concerned and used since the advent of man's use of metallic substances for protection against corrosion. Some of these products have been directed to the simple process of removing a rust or corrosion covered surface, while others have been addressed to solely a protective function. Other products have evolved that are directed to both functions, with some employing expensive chemical or other processes and products. A number of these products have been found to be cumbersome in use, while others have not been effective as a means for quick and effective removal of such existing rust or corrosive coverings. [0006]
  • The subject invention is conceived as an improvement over the existing products and processes that are used in this general area Consequently, the subject invention is directed as a specific improvement over the general area of products and processes used in this regard. Accordingly, the following objects of the subject invention are directed accordingly. [0007]
    • OBJECTS OF INVENTION
  • The following are objects of the subject invention: [0008]
  • It is object of the subject invention to provide an improved process for protection metallic surfaces from corrosion. [0009]
  • It is also an object of the invention to provide means to shield a metallic surface from rust or other corrosive processes. [0010]
  • An additional object of the subject invention is to provide an improved method of shielding a iron based structure from rusting . [0011]
  • A further object of the subject invention is to provide an improved method of removing corrosive products from a metal surface. [0012]
  • Yet another object of the subject invention is to provide an improved product for removing rust and/or corrosion substances from a metal surface. [0013]
  • A further object of the subject invention is to provide an improved method of preparing a metal surface for painting. [0014]
  • Still another object of the subject invention is to provide means to protect a metal surface from deterioration. [0015]
  • Other and further objects of the subject invention can be seen in the following description and claims read in view of the drawings herein. [0016]
