How is red-rust developed?
Development of red-rust starts when iron of water pipe releases electrons and iron ion is dissolved into water.
Red-rust “FeO(OH)” is developed when iron ion is reacted with Oxygen(O2) and water (H2O)
・Red-rust dissolves into water and causes red-water, clogging, degrade the pipe and eventually causes water leak.
How to stop development of red-rust
In reverse, red-rust development can be stopped if electrons are supplied to the iron that has just lost electron.
It is called “Electrolytic Protection”
How to reduce red-rust to magnetite.
Existing internal red-rust can be reduced to magnetite by continuous supply of electrons.
Magnetite is called “Passive State” material. It is very resistant to oxidation; it does not dissolve into water and is only 1/10th cubic size of red rust.
Magnetite provides protective barriers to inner wall of water pipe work. And extends life time of water pipe work for more than 40 years.
