Corrosion inhibitors and rust removers are protective agents that form a barrier between metal surfaces and water or corrosive chemicals to prevent rust or corrosion. One distinctive difference between the corrosion inhibitor and rust remover is that corrosion inhibitors reduce and inhibit the rate of corrosion of metals and other materials while rust removers are specifically designed chemical product that reacts on already rusted metals to remove rust and other forms of corrosion from metal. It reacts with the rust and dissolves it thereby preventing further damage to the iron metal.
Corrosion and rusting are two natural phenomena that we all have experienced at some point commonly seen in buildings that are wrecked, abandoned vehicles, shipyards, factories, equipment and machines. They both bring about the disintegration of the materials involved. However, interchangeably many at times we tend to confuse and misinterpret both chemical processes wrongly, but it is important to note that there are basic differences between them. Rust removers and corrosion inhibitors are protective agents that form a barrier between metal surfaces and water or corrosive chemicals to prevent rust or corrosion. They typically have lubricating or water displacement properties. Most rust-proofing products and moisture-proofing agents leave a film that stops water or corrosive substances from coming into contact with metal.
In order to understand the difference between these two? One must first know their definition and meanings. Corrosion and rusting are both oxidation reaction processes. The process of corrosion is basically a type of oxidation while rusting is a process for corrosion to take place. Corrosion occurs as a result of different materials being exposed to chemicals, but rusting only affects Iron that comes in contact with water or moisture.
What are Corrosion Inhibitors?
Corrosion inhibitors are basically chemical substances applied on any material, metals or non-metals as well as to the environment to reduce and inhibit the rate of corrosion of those substances, preventing unintentional degradation of the materials by chemical substances found in the environment. A coating process is experienced on the top surface of the materials, restricting penetration of water, chemicals, air, dirt etc. and making it unreactive to elements and chemicals through the process of passivation. This is known to be the first line of defense against corrosion.
Application of corrosion inhibitors are carried out;
- On surfaces of metals, non-metals and also to the environment
- In various fluids that are used in companies and industries such as in hydraulic fluids, engine oil, fuels, coolants and boiler water.
- In concrete mixture, when pouring concrete with steel rebar.
Compounds mostly present in corrosion inhibitors include glycols, nitrogen-based compounds, a solubilizer or diluent, sulfide, acetylenic alcohol, oxyalkylated naphthenic acid..
What Is Rust Remover?
Rust remover is a specifically designed chemical product that reacts on metals to remove rust and other forms of corrosion from metal. It reacts with the rust and dissolves it thereby preventing further damage to the iron metal. A rust remover depending on its effectiveness and efficacy has the ability to restore and revive an iron metal that was on the verge of corrosion there by inhibiting total damage and degradation of the material.
N/B: After the use of a rust remover on an iron metal, it is advisable to apply a corrosion inhibitor, this is to further give adequate protection to the metal object as there is no way to control natural elements like air, water or moisture in the environment from interacting with our objects, machine and equipment. This increases durability and brings about prolonged use of our equipment and machines.
Distinctive Differences between Corrosion Inhibitor and Rust Remover
1. The major differences between the Corrosion inhibitor and Rust remover is how they work
Inhibitors work in one of three ways, depending on the type as well as the environment in which they're used.
a. The inhibitor molecule readily diffuses into the metal surface by means of chemical absorption, forming a thin protective film in the form of a precipitate. This absorption process occurs either through self-interaction with the metal ions, or through interaction with other already-present metallic ions.
b. This protective film is made up of metal oxides that are formed when the inhibitor reacts with the metal. The increased corrosion resistance is a result of the metal oxide film.
c. The inhibitor reacts with a potentially corrosive substance in the water.
Rust remover, on the other hand, uses industrial acids to remove rust through chemical processes. This is a more efficient method than mechanical processes such as scrubbing or sanding/sand blasting, which can be time-consuming and labor-intensive.
2. The corrosion inhibitor is more suited for closed systems such as compressor and radiators, while rust removers are used on the surfaces of metals.
3. Corrosion Inhibitors are water based that is they have been dissolved in water and not concentrated.
4. They serve as both coolants and corrosion inhibitors in the closed system which makes them unique, which differs from a rust remover used mostly for protection of the outer surfaces of metals.
5. Another major different is their names for popular brands like Epochem they are distinguished as Corrosion Inhibitor and Rust removers.
