SU1286571A1 - Ceramic compound for manufacturing facing tiles and floor slabs - Google Patents

Abstract

The invention allows to increase the strength, frost resistance and Thermo-A resistance of facade tiles and floor tiles by using a ceramic mass containing, in wt.%: Clay 63-68, slag SDPP 20-30, manganese ore 1-2 and nepheline-syenite concentrate 6-10. The physical and mechanical properties of the tiles are as follows: firing temperature 1050-1080 ° C, water absorption 0.8-5.5%, frost resistance 50-75 cycles, bending strength 45.0- 50.2 Sha , abrasion 0.025-, 0.040 g / cm, heat resistance 10-16 cycles. 2 tab. i W

The invention relates to the building materials industry and can be used in the production of facade tiles and floor tiles.

The purpose of the invention is to increase (Strength, cold resistance and heat resistance of tiles.

The mass is prepared by the slip method by grinding in emaciated ball mills with the addition of 8–10% clay to 1-2% residue on a sieve No. 0056 and dissolving the rest of the clay component and then mixing them in the drain basins. The slurry humidity is 47-49%. Liquid glass and soda are used as electrolytes, in amounts of 0.2 and 0.08%, respectively (in excess of 100%).

The slurry is dehydrated in spray dryers to obtain a press powder with a moisture content of 5-6%. From the press powder obtained, tiles are pressed at a pressure of 22-26 MPa.

Drying and firing the tiles is carried out - ftjT in high-speed modes on the current

conveyor line: drying to a moisture content of not more than 0.1% at 200-280 0 for 20-25 minutes, roasting at 1020- 1080 G in a roller oven for 50-55 minutes.

The mixture compositions of the proposed masses are given in table. 1 and in table 2 properties of the tiles obtained on their basis.
