Vortex-layer devices as import-substituting equipment to produce paints and adhesives

It is proposed to use domestically produced vortex layer devices instead of imported bead mills for grinding pigments (and the synthesis of some of them) in the paint industry, for preparation of intermediates of film formers for the reduction of aromatic nitro-compounds to primary amines used as curing agents for epoxy oligomers, in the synthesis of dyes, etc. It is shown that using these devices results in not only technological advantages over bead mills, but will also allow us to replace some types of imported raw materials.
