一、概述为保证激光粒度仪计量校准结果的准确性和溯源性,依据JJF1211-2008《激光粒度分析仪校准规范》对仪器进行校准。所使用微粒粒度标准物质为聚苯乙烯微球,其颗粒具有团聚、间隙性的假颗粒、颗粒与颗粒之间具有一定的粘结力等不利于校准的特点,所以在计量校准过程中的一些校准条件,如使用分散剂与否、超声分散时长、遮光度的选择及搅拌速度等,都是对粒度仪进行准确计量的重要保障。现对实验过程探
I. Overview In order to ensure the accuracy and traceability of laser particle size analyzer measurement and calibration results, the instrument is calibrated according to JJF1211-2008 “Laser Particle Size Analyzer Calibration Specification”. The particle size of the standard material used polystyrene microspheres, the particles have agglomeration, the gap of the fake particles, particles and particles have a certain adhesion between the characteristics of the calibration is not conducive to, so some of the measurement calibration process Calibration conditions, such as the use of dispersant or not, the ultrasonic dispersion of time, the choice of opacity and stirring speed, are accurate measurement of the particle size analyzer an important guarantee. Now on the experimental process of exploration
