Our company manufactures backfill compound in the below-mentioned composition:
Graphite is the most stable form of pure carbon. It is relatively non-reactive and has high electrical conductivity. Hence is used in the backfill compound for better resistivity against the bad conducting nature of the soil. Due to its high electrical conductivity, it prevents current leakage.
It is used as a groundwater barrier to prevent the overflow of water into the compound.
3- Aluminum oxide:
It is amphoteric in nature i.e. can react with both acids and bases to produce salt and water. Therefore, it counter-affects the acidity or basicity of the soil and stops corrosion.
4- Iron oxide:
Iron oxide is also known as ferric oxide which is a chemical compound composed of iron and oxygen. Under conditions favoring iron reduction, the process of iron oxide reduction can replace at least 80% of methane production occurring by methanogenesis. This phenomenon occurs in a nitrogen-containing (N2) environment with low sulfate concentrations.
So, it counter-affects methane endorsed corrosion.
5- The Copper sulfate:
Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. Therefore, reduces organic corrosion.
6- Activated carbon
Activated carbon is also known as activated charcoal. It is used to chemically generate micro-fissures that greatly increase the area of its adsorption capacity.
So, it adsorps water at its surface to retain moisture in the mixture. And, hence enhancing its electrical conductivity.
