EFFECT OF BINDER AND LUBRICANT ON FLOW TIME AND APPARENT DENSITY OF IRON POWDER

The effect of binder and lubricant on the flow time and the apparent density of iron powder was investigated. The results show that, with the addition of 0.1% polyethyleneglycol, the flow time becomes shorter and the apparent density increases. Molybdenum sulphide has little effect on the apparent density, while the flow time is shorter with 0.2% molybdenum sulphide. The joint addition of polyethyleneglycol and lithium stearate has positive effect on the flow time and the apparent density. The joint addition of polyethyleneglycol and molybdenum sulphide can short the flow time, but has little effect on the apparent density.
