Abstract
A set of experiments to study physical and chemical modification of the surface of fibers is conducted to expand the area of their application for purification of water, gas and air (including that in conditions of space). The possibility of modification of filter nozzles in the process of fiber formation by particles of coal of BAU type, copper sulfide and silver chloride is experimentally shown. The fraction of the copper sulfide powder less than 50 microns in size was crushed in a spherical mill; it was deposited on fiber at air temperature of 50° C and powder consumption of 0.5 g/l of air. The resulting material contained 6–18 CuS particles per 1 cm of the fiber length. An effective bactericidal fibrous material can be produced using rather cheap material – CuS and relatively cheap natural compounds of sulphides and oxides of heavy metals.
Highlights
The development of various industries requires new approaches to purification of ventilation air and industrial gases
Sedimentation of active materials adsorbed on the fiber surface in water or water-organic solutions and interaction of these materials with the surface of the carrier-material with the following formation of the adsorptive material layer are the main methods of modification of fibrous materials based on polyolefins which
The fibers were produced from recycled polypropylene with a diameter of 100÷120 μm with powders of copper sulfide and silver chloride deposited on the surface using the installation (Figure 1)
