Nitrite Borax and Mercaptobenzothiazole (MBT) blended corrosion inhibitor suitable and well balanced formulation for Jacket Engine water system.
Various Grade of Corrosion Inhibitor http://rxmarine.com/search/node/corrosion RXSOL corrosion inhibitor is most popular for water treatment chemicals.
Types of Corrosion Inhibitor :
Anodic Inhibitors: A chemical substance that forms a protective layer of oxide film on the surface of metal causing resistance to corrosion. They are also known as passivators. It alters the anodic reactions in a chemical cell, forcing the metallic surface into the passivation region. There is a strong relationship between the anodic inhibitors and corrosion rate.
It helps to reduce the corrosion rate due to its retarding anodic reactions.
Following are the compounds been used as anodic inhibitors
-
Chromate
-
Nitrite
-
Molybdate
-
Orthophosphate
Cathodic Inhibitors: Cathodic Inhibitors are generally been used to prevent access to the corrosive substance or material. The effectiveness of cathodic inhibitors depends on the flow regime, water quantity and the fluid composition.
It helps to reduce the corrosion rate due to its retarding cathodic reactions. It forms an insoluble compounds precipitating on the cathodic sites in order to form a barrier film.
Following are the compounds used as cathodic inhibitors
-
Zinc salts
-
Calcium salts
-
Magnesium salts
-
Polyphosphates
Mixed Inhibitor: It is a type of enzyme inhibition in which the inhibitor may bind the enzyme. It is known as mixed inhibitor as it is a conceptual mixture of competitive inhibition and uncompetitive inhibition. Here the inhibitor can be bind only of the substrate is been already found.The compound formed reduces both cathodic as well as anodic reactions. In order to prevent formation of rust water silicates and phosphates is been used
Several things are to be considered before choosing with the corrosion inhibitors for your application:
-
Type of product whether it is oil, solvent of water based.
-
Consider environment, health and safety requirements.
-
Storage packaging and shipping conditions to be maintained according to temperature and humidity.
-
Methods of application that includes dip, spray, brush etc.
-
Define with the desired type and thickness of coating.
-
Materials to be protected.
Following are the compounds used as Mixed Inhibitor
There are various benefits of corrosion inhibitors which are been described as follows:
-
Liquids used in vehicles come in contact with metal parts. Using with this chemicals corrosion is been avoided
-
Corrosion inhibitors are been added to the vehicles as the metal parts get rust when comes in contact
-
Water systems get damaged due to the risk of rust, so the inhibitors are been added
-
Corrosion inhibitors are required for pipe, due to rust it can contaminate with the liquid passing through the pipe.
-
Tanks generally used to store water and fuel has the potential to get rust. It should be treated beforehand along with the corrosion inhibitors.
-
Corrosion inhibitors mitigate the corrosion rates of pipelines resulting in improved long-term pipeline integrity.
-
Along with the automotive industry there are other industries that benefits from corrosion inhibitors are open garden equipments, bike chains and loosen rusted scissor
-
Another sector that benefits with corrosion inhibitor is the construction industry as many of the metals used are vulnerable to weather
-
Metals like gates and railings are very much susceptible to rust, hence corrosion inhibitor is been used.
-
Corrosion inhibitor extend the lifespan of the equipment up to 250%
-
Reduces the cost of repair due to corrosive damage
-
If the equipment is protected, service interruptions and operation malfunction can be avoided
-
For companies having corrosion inhibitor equipments, can avoid legal and environmental liabilities
