Description

 The invention relates to the production of decorative-facing materials based on glass.

A known method of obtaining decorative facing material synthesized on the basis of sand, cullet and dye, loaded into the form with subsequent heat treatment [1]
However, the resulting facing material has low decorative properties due to the possibility of quartz sand coming to the surface and complicated manufacturing technology.

The closest to the proposed technical essence and the achieved effect is a method of obtaining decorative facing material, including forming a tape from a glass melt, cooling in air, applying adhesive and coating to its upper and lower surfaces, heat treatment and separation into tiles [2]
The disadvantages of this production method include the complex manufacturing technology, insufficiently high physical and mechanical properties and decorative effect.

 The objective of the invention is to improve the physico-mechanical properties and decorative effect.

This is achieved by the fact that in the method of manufacturing a decorative facing material, including molding a tape from a glass melt, applying a decorative coating to the upper surface of the tape, heat treatment and dividing into tiles for forming the tape, melt glass of the composition, wt. SiO ₂ 52.7-64.4; Al ₂ O ₃ 4.0-6.7; CaO 18.35-27.3; Fe ₂ O ₃ 1.5-2.3; MgO 2.0-2.9; TiO ₂ 0.38-0.54; Na ₂ O 2.8-5.0; K ₂ O 2.0-2.87; P ₂ O ₅ 0.01-0.8; MnO 0.1-0.15; S ² 0.26-0.6; ZnO 0p, 01-2,0, cooling steps lead to annealing of 670 to 620 ^{° C} for 30-45 min, and then separation is carried out on tape tile followed by coating and heat treated at 850-950 ° ^C.

Besides, the task set is achieved in that in the method harvested decorative facing material for forming the glass ribbon using the above composition, coating is performed on a hot strip at 600-750 ^C, and heat treatment is conducted at 850-950 ^{° C,} then cooled and divided into tiles.

 To improve the adhesion of the tiles to the cement mortar and uniform crystallization of the substrate, the lower layer of the glass tape can be molded in relief.

 Glasses within the specified composition were synthesized based on the ashes of an Estonian state district power station and additives: waste phosphate enrichment from the Kingisepp deposit or sand, soda ash, zinc oxide, waste from the production of electrode coke PO Slantsekhim (Kohtla-Järve) (Table 1).

As an enamel coating used for fighting termometrovyh glasses and decorative glass in the form of granules having a particle size of 0,6-5 mm, CTE (78-95) x10 ^-7o C ^-1 and the temperature spreading 850-950 ^C.

 During the heat treatment, the substrate (glass tape) crystallizes in bulk and acquires a finely dispersed structure corresponding to the ceramic.

PRI me R 1. From molten glass melt composition 1 (table 1) forlente two rolling rolls, and the lower layer is formed in relief. Cooled stepwise with annealing at 620 ^{° C} for 45 minutes, then the separation is carried out on tape tiles. Tiles are laid on trays, then applied to the top surface of the tile granules battlefield enamels for glass termometrovyh (compositions given in Table. 1) with the size of 3,15-5,0 mm and subjected to heat treatment at 950 ^{° C} for 30 min. In the process of heat treatment, the enamel battle granules melt and form a peculiar spotted pattern resembling natural stones.

 Decorative and cladding material with a smooth back can be used in the furniture and jewelry industries, and upon receipt of a relief lower layer of glass tape for facing internal and external walls.

 Physico-mechanical properties of the obtained decorative facing materials are given in table 2.

 The proposed production method allows to improve the decorative and physico-mechanical properties of the material. The material can have almost any color in bright rich tones or muted pastel, and in some cases an aventurine effect. The presence of a large selection of multi-colored material makes it possible to obtain not only a single-color surface of the walls when they are lined, but also to lay out ornaments and even from plates that are beautifully combined with each other, which gives the building objects a finished look and architectural expressiveness.
