ScaleAwayPPE concentrate is a corrosion inhibitor used to protect the underlying metal when scale and oxide deposits are removed with ScaleAway’s bio degradable and eco friendly “green” acids.
ScaleAwayPPE concentrate is added to solutions of descaling chemicals that are used to remove rust and scale from metal parts. It has a passivating action on bare steel in the scale removal processes which prevents the underlying metal from being corroded without interfering in the scale removal process.
Passivation is the process of making a material "passive", usually by the deposition of a layer of oxide that adheres to the metal surface. Passivation affects the properties of almost all metals. In the context of corrosion, passivation is the spontaneous formation of a hard non-reactive surface film that inhibits further corrosion. This layer is usually an oxide or nitride that is a few nanometers thick and will inhibit calcium carbonate scale from adhering to the metal for a period of 3 months.
ScaleAwayPPE concentrate is also very effective in cases in which very uneven deposits need to be removed with mineral acids. The acid solution is circulated to increase the rate at which the scale is removed. The duration of the process depends on the thickness of the deposits and the accessibility of the steel surfaces to be treated in oil coolers and heat exchangers, etc.
The descaling solution can be circulated to increase the rate at which the scale is removed. The duration of the process depends on the thickness of the deposits and the accessibility of the steel surfaces to be treated in pipe work and reactors, etc. It is usually sufficient to treat the metal for 1 – 4 hours at 40 – 60 °C in order to remove scale deposits.
