| titleOfInvention | Method of processing gypsum into sulfur dioxide and binder |
| abstract | The invention relates to chemical technology for the processing of gypsum-containing materials, in particular, to methods for processing gypsum to sulfur dioxide and to the effect of decomposition in a melt by the electrothermal method, and may find application in the production of sulfuric acid and building materials. The purpose of the invention is to intensify the process and obtain a scientific research institute in the field with increased hydraulic activity. The method is carried out as follows. Gypsum and silica are mixed in a ratio of SiO "and CaO 0.71-0.82. Boron and iron (III) oxides are added to the mixture in an amount of 4.0-5.0 and 1.8-4.0 wt.%, Respectively. The resulting mixture is granulated, dried to a residual moisture content of 0.05-0.1 wt.%, And thermally treated to produce a melt in an electric arc furnace at 1250-1350 ° C. Complete - desulfurized does not take place in minutes. Shpak has hydraulic activity according to GOST 310-4-81, 2-25.7 MPa. 1z.p. f-ly, 1 tab. (L with: |
