METHOD FOR OBTAINING CERAMIC MATERIAL Russian patent published in 2021 - IPC C04B33/132 

FIELD: construction materials industry.

SUBSTANCE: invention relates to the field of construction materials technology and can be used for the production of building ceramic products. The method for producing ceramic material includes drying, grinding of clay raw materials and subsequent mixing of the components of the raw mixture, moistening until a press powder is obtained, its semi-dry pressing, drying and firing of products, pre-solid pyrolysis residue of partially sorted MSW is crushed to obtain a fine powder with a particle size of no more than 0.1 mm, low-melting clay is crushed, dried at a temperature of 80°С to a humidity of 3%, ground to obtain particles of no more than 0.1 mm, the resulting powders are mixed at the following component ratio, wt. %: solid pyrolysis residue of partially sorted MSW 20% and low-melting clay 80%, the powder mixture moistened to 10%, formed and dried at a temperature of 100°C to a humidity of 3%, and then burned at a temperature of 1000°С, the burnt powder mixture is ground, obtaining a fine thinning additive with a particle size of no more than 0.1 mm, clay raw materials, namely low-melting moderate plastic clay is ground to particles with a size of no more than 0.1 mm, the components raw material mixture are mixed at the following ratio, wt. %: low-melting moderate plastic clay 60-70% and fine thinning additive 40-30%. Partial sorting of MSW is carried out by removing plastic and polymers from them. Pyrolysis of partially sorted MSW is carried out at a temperature of 700°С.

EFFECT: production of ceramic material for the production of ceramic products that meet the National Standard requirements the expansion of the raw material base, the disposal of solid municipal waste.
