Petroleum Coke Backfill
PETROLEUM COKE BACKFILL Petroleum Coke Back fill is designed for use in critical deep well or conventional ground bed. The back fill lowers anode-to-earth resistance, provides a uniform environment for current discharge, and extend the anode's design life. Deyuan supplies the superior choice for back fill in critical deep well or conventional ground beds when resistivity is the major consideration. The standard packaging for the back fill is 50kg per bag.Since the purpose of the carbonaceous back fill is to provide an electronic path for current flow, low resistivity, particle size and specific gravity are important back fill properties. Low resistivity favors electronic current flow to the back fill/ground interface. Small particle size and high density favor electronic current flow between the anode material and back fill by improving contact between the anode material and back fill.SpecificationsFixed Carbon99%Ash0.5% MaxMoisture0.2% MaxVolatiles0.5% MaxBulk Density1100kg/CBMResistivity0.1ohm.cm MaxSize0~1mm
