FILTERING SORPTION INSERTION PIECE WITH REDUCED INFLAMMABILITY FOR OZONE TRAPPING

摘要

The filter sorption insert with decreased combustibility for ozone collection consists of at least one filter sorption layer. This layer is an adsorption non-woven fabric that either consists of 10 to 50 percent by weight of chemical or mineral fibres, 10 to 40 percent by weight of acrylic or styrene acrylic binding agent, 4 to 18 percent of diammonium hydrogen phosphate, 20 to 60 percent by weight of pulverised activated carbon or spherical carbon sorbent and 1 to 7 percent by weight of soda-ammonium salt or acrylic polyelectrolyte, and/or of sorption carbon fibres.
