«In the majority of discussions and tests with companies, they always ask the same question: Does the use of IDEPS cause corrosion? Doesn’t the fact that when we are using IDEPS to solve biofilm problems in different areas of our production lead to an increased formation of corrosion?»
According to Alexander Koval, managing partner of IDEPS and responsible for research and development in the company, this is a frequent question asked when IDEPS is discussion the use of this innovative agent with customers.
Only in the industrially developed countries corrosion damage per year is in average about 3-5% from gross domestic product. Furthermore, about 20% from all metal, produced in the world per year, is lost during the process of corrosion.
«The fact that corrosion leads to significant losses substantially undermining the enterprise budget makes it important for us to conduct research and receive an answer to the question about the risk of corrosion formation when using IDEPS in the fight against biofilms»explained Alexander Koval
Standardized tests like sandwich-tests took place with black steel (Types E235JR, S235JR, Fe360B).
As the result of those tests, we learned that the speed of steel corrosion in a solutions of 50% and 100% of IDEPS is two times lower than in water without IDEPS. Also, in these solutions no formation of iron (Fe) oxidation on the surface of the steel products was detected.
During the tests with 50% and 100% of IDEPS solutions, no products of corrosion were found.
