摘要
MoS_(2)是重要的固体润滑剂,粒度检测和控制是提升MoS_(2)粉体产品质量非常重要的一个环节,但激光粒度测量方法受技术原理限制,测试结果易受测试方法和设备的影响。本试验采用欧美克激光粒度仪对MoS2粒度及粒度分布进行分析,研究了当设置超声分散时间为3min、泵和搅拌速度为1000~2000r·min^(-1)、遮光率10%~20%时,粒度检测结果较准确,稳定性较好,同时采用其它粒度分析仪对同一样品进行了比对分析,结果显示相对标准偏差在可接受范围内,试验重现性良好。
Molybdenum disulfide is an important solid lubricant.Particle size detection and control are a very important part of improving the quality of molybdenum disulfide powder products.However,laser particle size measurement methods are limited by technical principles,and test results are easily affected by test methods and equipment.This experiment uses the Omega laser particle size analyzer to analyze the particle size and particle size distribution of molybdenum disulfide.When the ultrasonic dispersion time is set to 3min,the pump and stirring speed are 1000 to 2000r·min^(-1),and the shading rate is 10%to 20%,the particle size detection results are studied.It is more accurate and stable.At the same time,compared and analyzed the same sample with other particle size analyzers.The results show that the relative standard deviation is within the acceptable range and good reproducibility.
