摘要
利用振筛机筛出机制砂中石粉和泥土的混合物,利用泥土对亚甲蓝的吸附性,通过滴定亚甲蓝,在亚甲蓝值和泥土含量的线性关系图中找出该亚甲蓝值下泥土的含量,就可以得出石粉的精确含量。
The mixture of stone powder and clay in the machine-made sand was screened out by means of vibrating screen machine.The adsorption of methylene blue by clay was used to determine the clay content in the linear relationship between methylene blue and soil content by titration under a certain methylene blue value,so as to get the exact content of stone powder.
