Description

The invention relates to the glass industry and can be used as a decorative cladding material.

The goal is to increase jamming and mechanical bending and compression strengths.

To obtain stewed glasses use the following source materials. May, May. %: perlite of the Aragats deposit in the Armenian SSR 30-70; tuff of Artik deposit of the Armenian SSR 30-70 and introduced into the charge in excess of 100% soda ash, Ma2COz 5.5 - 18.5, GOST 21302-76 and crema eptorite sodium NaaSiFe 6.5-8 5 GOST 87-77.

The glass melting temperature is 1330-1470 ° C, the dwell time is 2 hours. Glass mass killing occurs during production and in bulk.

From the finished glass, you can get tiles by two methods:

tiles are cast or pressed, then the resulting tiles are annealed at 600-653 ° C with an exposure of 1 hour; tiles are cooled at a rate of 60 ° C / h to 25 ° C;

the finished glass melt is poured into a tank with cold water and glass granules are obtained; HS-based glass granules are obtained glass-glassy material, cellall-remor, in a crumbly box; The bottom of the box is filled with vac sand with unit sand, then with a mixture of rpSHv- glass. tal of quartz sand, prichgotlennoi in the ratio of 3: 1, thickness lC i2 mm, the top layer is covered with glass-fiberglass with a thickness of 10 ill mm; the filled box is loaded into an electric oven; heat treatment mode: at 900 ° C withstand 30 minutes, cooling samples

ha

occurs arbitrarily: the front surface is smooth with fiery polishing, the color of the tiles is light green.

Specific compositions of glasses are given in Table. 1, the properties of glasses - in the table. 2

As can be seen, this glass has a high degree of damping, high limits of flexural and compressive strength.

The annual economic effect of the introduction will be approximately 10,000 RuoGod.
