MAGNESIA BINDER, METHOD OF PREPARING MAGNESIA BINDER, AND PRODUCT

摘要

FIELD: production of inorganic compounds. SUBSTANCE: binder contains 50-70% of fly ash from caustic magnesite production and 30-50% of sludge waste from bisulfite pulping process. Components are mixed and mixture is treated for 1 to 5 min in hydroacoustic disperser at frequency 300- 900 rpm, temperature 20-40 C, and water-to-solids ratio 0.6. Resultant binder or its mixture with additives and/or fillers is of value in manufacturing various articles. EFFECT: reduced cost due to waste components utilized. 4 cl, 1 tbl
