固体润滑材料高纯二硫化钼生产工艺改进

Improvement of production process for high purity molybdenum disulfide solid lubricant material

通过对原有生产工艺进行改进,加入除铁专用的助溶剂,变原有多段除铁为一段除铁,使生产过程周期由原工艺的24 h缩短为15 h,生产效率提高50%,酸性废水减少60%。加入除铁专用的助溶剂,使铁的去除率由原工艺的78.0%提高到93.3%。通过生产连续运行考察,在最佳操作条件下,产品中铁质量分数降低到0.08%,收率由原工艺的88%提高到93%,经济效益显著。

The original production process is improved with the addition of specific co-solvent for removing iron and one stage removal of iron replacing multi stage removal of iron for a period in addition to iron. After improvement,the production cycle is shortened to 15 hours from the original 24 hours,the production efficiency increases by 50%,and emission amount of acidic wastewater reduces by 60%. With the addition of specific co-solvent,the removal rate of iron increases from 78. 0% to 93. 3%.Through continuous operation,the iron content in the product drops to 0. 08% under the optimum operating conditions,and the yield increases from 88% in original process to 93%. The economic benefit is remarkable.
