粒径分布快速分析新方法在土质研究中,迄今为止仍然采用筛分法确定泥样的粒径分布这种方法很费时,特别是潮湿泥样必须烘干,因此更费时间了,在实验室用筛分法进行粒径分布分析,对于那些质量控制很严格的砂和砾石的承包商和用户来说,是时间长成本高的过程。荷兰IHC研究和开发研究院在肯德代克的荷兰MTI公司,研制了沉积柱筒,它能在5分钟内提供精确的粒径分布。该仪器提供的结果在质量上能与传统的筛分技术提供的结果相妣美,沉积柱筒的操作是
A New Method for Rapid Analysis of Particle Size Distribution In soil research, sieving has been used so far to determine the particle size distribution of mud samples. This method is time-consuming, in particular because wet mud samples must be dried and therefore takes more time, The particle size distribution analysis by sieving is a time-consuming and costly process for contractors and users of sand and gravel that are subject to stringent quality control. The Netherlands IHC Research and Development Institute in Mudderdijk MTI company in the Netherlands, developed a deposition cylinder, which can provide accurate particle size distribution within 5 minutes. The results provided by this instrument are qualitatively comparable to those provided by conventional screening techniques. The operation of the deposition cylinder is
