Abstract

Способ определения коэффициента массопроводности пористых проницаемых материалов, включающий определение величин, входящих в кинетический закон массопередачи, а именно: массы вещества, движущей силы процесса массопередачи (разности потенциалов сред) с обеих сторон материала, поверхности материала, времени процесса, отличающийся тем, что одновременно при одних и тех же параметрах процесса проводят измерения указанных величин для двух или более образцов одной и той же природы, но разной толщины, исключая измерения параметров на поверхностях материалов, а затем рассчитывают искомый коэффициент массопроводности по полученной аналитическим путем формуле,при этом, в данной формуле выражена количественная доля разности потенциалов на поверхностях материала, т.е. движущей силы массопереноса механизмом массопроводности, от общей движущей силы процесса массопередачи от одной среды к другой через проницаемый материал.A method for determining the mass conductivity coefficient of porous permeable materials, including determining quantities included in the kinetic law of mass transfer, namely: the mass of the substance, the driving force of the mass transfer process (potential difference of the media) on both sides of the material, the surface of the material, the process time, characterized in that at the same time the same process parameters measure the indicated values for two or more samples of the same nature, but of different thicknesses, excluding the measurement of parameters on the surface styah materials, and then calculating the required mass conductivity coefficient obtained analytically by formula, wherein, in the formula, expressed quantitative proportion of the potential difference on the surfaces of the material, i.e., the driving force of mass transfer by the mass transfer mechanism, from the general driving force of the mass transfer process from one medium to another through permeable material.
