Novel full-component granularity analysis method for siltstone particles

Abstract

The invention relates to the field of analysis for chemical components, and in particular relates to a novel full-component granularity analysis method for siltstone particles. The method comprises the following steps of: analyzing a siltstone sample, judging the species of the siltstone sample, extracting an original sample from the classified siltstone sample, preparing an analysis sample through the original sample, adding clean water into the analysis sample, uniformly stirring the analysis sample and the clean water to form a turbid solution, adding the turbid liquid into a dispersing agent in a sample tank of a laser particle analyzer through a dropper, performing ultrasonic dispersion on the turbid liquid in the dispersing agent in the sample tank for certain time to obtain ultrasonic dispersion liquid, and performing granularity analysis on the dispersion liquid. According to the method, an analysis result obtained by the laser particle analyzer is accurate, and the granularity and the distribution of siltstone can be really reflected.

Description

technical field [0001] The invention relates to the field of chemical composition analysis, in particular to a new method for particle size analysis of all components of siltstone particles. Background technique [0002] Grain size analysis is to study the grain size and distribution of clastic rocks, so as to judge the natural geographical environment and hydrodynamic conditions during deposition, and provide a basis for phasing analysis of sedimentary facies. For siltstone, it contains more mud-clay grade particles, fine particles. In the process of analysis sample preparation and testing, it is necessary to ensure that the grades are from coarse to fine, and all grades of rock particles are preserved, so as to ensure that the analysis results are more real and accurate. [0003] In related technologies, a laser particle size analyzer is used to analyze an analysis sample, and a relatively accurate analysis result can be obtained. The object of particle size analysis by ...

Problems solved by technology

This method will make the mud-clay level fine particles in the solid particles adhere to the tank wall above the liquid level of the dispersant in the sample tank due to the rotation of the dispersant, resulting in coarser particles that the instrument can only detect , which leads to deviations in the analysis results, which cannot truly reflect the particle size and distribution of rocks.
