Data measuring system to determine the solvent diffusion coefficient in products from capillary-porous materials

Abstract

Abstract The development of methods and means for non-destructive product testing is the current task of modern instrument-making in the study field of porous materials ability to transport the substances distributed in a solid phase. They allow one to determine the characteristics of mass transfer directly in the finished product, because they do not require the preparation of special samples of a given configuration and size, typical for most of the used methods and devices. The aim of this study is to develop data measuring system that improves the performance of studies of polar solvents diffusion in porous media. The data measuring system is designed to implement methods of the solvents diffusion coefficient control in fine and bulk products from isotropic and anisotropic porous materials with one-way access to flat surfaces of specified size products. The schematic of the data measuring system, virtual surface for experiment control, the flow chart for the measurement operations of the developed methods, the results of testing the system are given.
