Technology Obtaining of Highly Efficient Powdered Filtering Materials for Cleaning Liquids and Gases

Abstract

The work is devoted to development of technology for the production of highperformance powdered filtering materials (FM) on the basis of titanium carbide by dry radial-isostatic pressing (DRIP) method with followed their sintering by self-propagating high-temperature synthesis (SHS). Developed technology of obtaining gradient multilayer filtering materials with uniform and regulated porous structure on volume by method of a stepwise multilayered radial-isostatic pressing of various by nature and composition powder materials (PM) which provides the obtaining FM with variable pore sizes in the direction of filtration. Obtained by us gradient FMs have considerably higher permeability, pollutant capacity and service life in comparison to existing analogues. The developed technology of a step-by-step DRIP of sealing materials also allows receiving high-performance FM new generation with unique operational properties, which today is virtually impossible to obtain by other methods.
