摘要: 加入聚乙二醇、硬脂酸锂、二硫化钼及同时加入聚乙二醇和硬脂酸锂、聚乙二醇和二硫化钼,对铁粉流动性和松装密度的影响作了研究。结果表明,聚乙二醇加入0.1%时可以较大提高铁粉的流动性和松装密度;硬脂酸锂加入0.2%~0.5%时能较好改善铁粉的流动性和松装密度;二硫化钼加入0.2%时对铁粉的流动性有较好的改善,但二硫化钼对改善铁粉的松装密度效果很小;同时加入聚乙二醇和硬脂酸锂对铁粉流动性和松装密度的改善有很好的效果。二硫化钼和聚乙二醇同时加入时可以提高铁粉的流动性,但对松装密度影响不明显。Abstract: 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.
