Process and product for application for preserving metallic
products from corrosion
Abstract
The subject invention is a process for preserving metallic
products from deterioration from corrosion or oxidation, comprising
the application of a protective product including the following the
steps of applying, (a) cleaning the exterior of the metallic
product of removing scaling or other externally disposed by
products of corrosion; (b) applying a corrosive removal substance
comprised of water, ammonium components, alcohol and a solvent
premix which is in turn comprised of alcohol and mineral spirits.
The subject process may include the further process of painting the
surface of the metallic surface after the above described
anti-corrosive substance is applied and in some cases removed.

Description
DISCUSSION OF PRIOR ART AND BACKGROUND OF THE INVENTION
[0001] 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.
[0002] 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.
[0003] 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;
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
OBJECTS OF INVENTION
[0008] The following are objects of the subject invention:
[0009] It is object of the subject invention to provide an improved
process for protection metallic surfaces from corrosion.
[0010] It is also an object of the invention to provide means to
shield a metallic surface from rust or other corrosive
processes.
[0011] An additional object of the subject invention is to provide
an improved method of shielding a iron based structure from rusting
.
[0012] A further object of the subject invention is to provide an
improved method of removing corrosive products from a metal
surface.
[0013] Yet another object of the subject invention is to provide an
improved product for removing rust and/or corrosion substances from
a metal surface.
[0014] A further object of the subject invention is to provide an
improved method of preparing a metal surface for painting.
[0015] Still another object of the subject invention is to provide
means to protect a metal surface from deterioration.
[0016] Other and further objects of the subject invention can be
seen in the following description and claims read in view of the
drawings herein.
DESCRIPTION OF GENERAL EMBODIMENT AND SUMMARY OF INVENTION
[0017] In the most general form of the embodiment of the subject
invention, the process in this case involves the following general
steps as an overall basis for implementation of the subject
invention.
[0018] (a) clearing the rough scales and corrosive substances;
[0019] (b) applying a corrosive removal substance comprising
generally of water, ammonium components, alcohol and a solvent
premix which is comprised of alcohol and mineral spirits;
[0020] The subject process may include the further process of

described anti-corrosive substance is applied.
[0021] It is to be stated that the above process and above
discussed substances can be used on all types of metallic
substances and may be applicable to all types of corrosion on any
type of metallic surface.
DESCRIPTION OF PREFERRED EMBODIMENT
[0022] In describing the preferred embodiment of the subject
invention it is to be stressed that the following description is
only of one specified embodiment of the invention. In so describing
a specified embodiment no limitation on the scope of the subject
invention will be construed as a result. Further, in describing the
subject invention and the components of the anti-corrosive
substance it is to be understood that the individual components, as
specifically delineated, may include other compounds or elements

[0023] In the most general form of the embodiment of the subject
invention, the process in this case involves the following general
steps as an overall basis to implementation of the subject
invention.
[0024] (a) clearing the rough scales and corrosive substances;
[0025] (b) applying a corrosive removal substance comprised of
water, ammonium components, alcohol, and a solvent premix which is
in turn comprised of alcohol and mineral spirits;
[0026] More specifically the product which incorporates features of
more particularly delinated substances include the following
substances in ratios specified.
1 A Water 77.00 B Ammonium molybdate 00.10 C Rhodafac RE-610 1.91 D
Triton x-100 0.48 E Tetrahydro furfurrly alcohol 2.31 F Phosphorus
acid 18.20 100.00
[0027] In this latter formulation, the water and ammonium hydrate
are intermixed until the ammonium hydrate is dissolved, with all
remaining specified substances being intermixed while basic water
and ammonium are in the process of being mixed.
[0028] In an alternate embodiment of the subject invention, the
following components are intermixed.
2 A Water 77.50 B Ammonium molybdate 00.10 C Rhodafac RE-610 1.91 D
Triton x-100 0.48 E Solvent Premix 2.81 F 75% Phosphorus acid 18.20
100.00
[0029] The solvent premix issued in this latter formulation is:
3 Tetrahydro furfuryl alcohol 82.2 Odorless mineral spirits 17.8
100.00
[0030] As can bee seen with this latter formulation a solvent
premix is used, such solvent premix being comprised of tetrahydro
furfilryl alcohol at a ratio of 82.2% and mineral spirits,
preferably odorless, at a ratio of 7.8%. As can be seen in this
latter embodiment the solvent pre-mix is used in place of
tetrahydro furfuryl alcohol
