(54) METHOD OF MANUFACTURING DECORATIVE-FACING TILES

(57) The invention relates to the washing of building materials, to the production of decorative facing tiles obtained by sintering and intended for internal

and exterior architectural decoration of industrial and civil buildings and structures. The aim of the invention is to increase the strength of the plates during bending, their adhesion to the cement mortar, as well as shrinking the consumption of diamond tools for cutting. A method of manufacturing decorative facing slabs consists in sequentially placing in a form on a layer of quartz sand the main layer of the composition, wt%: phosphoric slag granules 61-75J glass powder 18-33; A 25% solution of liquid glass 6-7, the ratio of the lower layer to the upper layer being 70-75: 25-30. Flexural strength is up to 17.1 MPa, adhesion to cement mortar is up to 1.7 MPa. 2 tab.

bending of the slabs, their adhesion to the cement mortar, as well as reducing the consumption of diamond tools for cutting.

Decorative facing plates are made as follows.

Phosphoric slag granules with a fraction of 0.5–3 mm and a 25% liquid glass solution are loaded into the mixer, which are subjected to mixing until the surface of the granules is wetted with a solution of liquid glass. Then load the powder glass obtained from the waste container, window glass, and continue mixing. After this phosphorus slag granule, coated with glass powder, is placed in ceramic or cast-iron molds on a layer of silicate sand 2 mm thick, to prevent the slab from sticking to the mold. Then the top layer of colored glass granules is applied, the ratio of the top and bottom layers is 25-30: 70-75. The plates are burned in a tunnel kiln at 900– for 20–30 min.

Phosphoric slag used to make a decorative facing material has the following chemical composition:

u so that, in order to increase the strength of the plates during bending, their adhesion to the cement mortar, as well as to reduce the consumption of diamond tools for cutting, the composition of the main layer is prepared by treating the phosphoric slag granules with a fraction of 0.5-3 mm 25% -nm-solution of liquid glass, followed by mixing with powder of glass in the following ratio of components, wt.%: Phosphoric slag granules61-75 Glass powder 18-33 25% solution of liquid glass 6-7, and the ratio of the main layer to decorative- Facing is in May. /
