| 摘 要： | 根据英国马尔文Mastersizer 2000型激光粒度仪的特点,探讨不同技术参数对样品粒度分布测试结果的影响。结果表明,影响样品粒度分布的主要参数为样品量(检测遮光度)、采集时间、循环速度、检测光源波长、反演光学模型及数学模型等;对于状态不明确的未知样品,应借助其他检测技术进行样品状态表征后,选择合理的光学模型和数学模型进行粒度测试。

| Abstract: | According to characteristics of Mastersizer 2000 type laser particle size analyzer from Malvin Instrument Co.Ltd.,the influence of different technical parameters on test results of particle size distribution was investigated.The results show that the main parameters affecting particle size distribution are the amount of sample(detecting light obscurations),collecting time,circular velocity,wave lengh of light,inversed optical model,mathematical model and so on.For unknown sample with unclear state,other analytic technique should be used to represent the sample state,and then correct optical model and mathematical model should be chosen to analyze the particle size. |
