How Migrating Corrosion Inhibitors Work
QED manufactures a range of Migrating Vapour Phased Corrosion Inhibitors (MVPCI's or VPI's for short) The way they work is easily explained.
The chemical elements within our product are given off as a vapour which will saturate a given airspace to a specific density, this vapour will form a mono-molecular coating on exposed and/or embedded steel, forming a barrier to further corrosion. The migrating part of the product, means that at a molecular level, the VPI will travel through not just air, but also seemingly impermeable dense materials (in fact there are micro pores in concrete allowing a fine vapour to travel through it) such as concrete (please see our Trials page for a real demonstration of the effectiveness).
The picture above left graphically shows the three elements in our Margel product inserted in reinforced concrete,
Given these unique properties, there are many real world problems that can be addressed by such products.
QED's range of products are suitable for many specific problem areas, such as protection of reinforced concrete structures, steel ship hulls, steel components for the automotive and aviation industry, products for the oil refining industry, ..........
