Usе of production chromium containing wastes as secondary raw materials
The article presents the results of studies of large-tonnage wastes processing, i.e. removal of toxic compounds of hexa-valent chromium from the wasted chromia-alumina catalyst. The authors presented compositions of paints, lacquers, enamels, fillers and primers. A schematic diagram of the system for preparation of lacquer-paint materials is offered. Fig. 2, table 5, ref. 9.
