Description

one

The invention relates to the production of building materials, namely glass tiles for cladding external and internal walls.

A known method for producing a facing tile is by rolling crystallizing glass mass, coating a glass sheet on it, and then sand, followed by heat treatment and sheet cutting into formats 1.

The technology for producing tiles (crystallizing glass - glass - sand) is very complex (without the use of waste), and the strength of the tile is small.

Most closely to the proposed method, in which an enamel layer is applied to the front side of the glass tile. The tile with the dried coating is placed on the sandy surface of the trolley with a smooth, non-enamelled side, heated, sintering is carried out - burning the enamel coating, and then annealing and cooling the tiles 2.

Tiles made in this way have enamel facial and back rough surfaces. Roughness is obtained by glass. It is impractical to use such a tile for facing external walls due to low adhesion with mortars; due to the aggressive effects of the environment, the adherence is still reduced; The ornamental properties of the famous tiles are very low, the enamel layer is subjected to mechanical and atmospheric influences.

The purpose of the invention is to increase the durability of the tile.

This goal is achieved by the fact that in the manufacture of glass tiles

Q in a way that enamels are applied to the glass preform, the substance, the filling of sand, the laying of the preform in the form upwards with enamel, and the heat treatment. After drying, the billet is heated to 100-110 ° C, and sand is deposited on the enamel with particles of no more than 0.8 mm.

As a result of the formation of rough

enamelled surface rises

adhesion bond strength

with mortars, and consequently, the duration of the facing coating increases, the resistance to weathering increases dramatically and, as a result of the foregoing, it is possible to use the proposed

25 tiles for facing exterior surfaces of buildings and structures. An example of the method. Billets 150X150 mm in size are laid close to the wooden pallets.

30 Over the conveyor, pallets are manually fed.

in the spray booth. Then billet-. covered with enamel slip by the method of spraying the KR-Yu spray gun with compressed air. Enamel applied titanium with a titanium oxide content of 17.9%.

The enamel-coated tiles are then dried under natural conditions on pallets that leave the pulverizing chamber along a roll table. Dried tiles are laid on trolleys, heated to 120-150 ° C, and they are dried.

The heated tiles are laid on the tunnel wagons with the enamelled side up and sprinkled with a layer of sand with a particle size not exceeding 0.8 mm (screened on sieve No. 100). 36 pieces of tiles are laid on each trolley. A gap of 2-3 mm is left between the tiles. Then the tiles are fired in an electrically heated tunnel kiln.

Temperature condition along the length of the furnace:

-heating zone: 1- point - 370 ° С; 2- point - 660 ° С;

- zone agglomeration: 3- point - 720 ° С; 4- point - 780 ° С;

- annealing zone: 5- point - 750 ° С; 6- point - 530 ° С;

- cooling zone: 7- point - 350 ° C;

- at the furnace exit, the tile has a temperature of 90-100 ° C.

The time of passage of the trolleys along the entire length of the furnace is 40-50 minutes.

This method produces colored tiles with a smooth, transparent face.

The back side of the tile is enameled (of any color) and has a rough surface. Its back side is attached to the wall, and the transparent part of the glass protects the enamel from mechanical and chemical influences.

The use of glass cladding enameled tiles allows us to solve the problem of increasing the color expressiveness of the interior and exterior walls of industrial, residential and civil buildings, and also provides significant savings in material resources.

The invention will improve the durability and durability of glass tiles.
