- Abstract
Consideration is given to the problem of determination of the range of variation of the regime parameters of the process of measuring the diffusivity of solvents in massive products manufactured from capillary-porous materials with the aim of improving the efficiency and accuracy of the employed nondestructive-testing method. The order of implementation of measurement operations of the developed method is determined as a result of the performed investigations. The accuracy in determining the sought diffusivity is improved due to the concentration maximum of the solvent falling within the rational range of the static characteristics of a galvanic sensor used to monitor the local concentration of solvents. Reduction in the expenditure of time and funds is ensured by eliminating the need for individual calibration of the measure of concentration of solvents of the analyzed materials in a solid phase for each new system ″capillary-porous material-solvent,″ and also for numerous trial experiments with different volumes of a pulsed-action dose to improve the accuracy of the method.
