SU1260359A1 - Ceramic compound for manufacturing facing tiles - Google Patents

Description

"I

The invention relates to the industry of building materials, mainly to compositions of masses for the preparation of facing tiles for external and internal facing.

The purpose of the invention is to increase strength, reduce water absorption and shorten the time of high-speed firing of tiles.

Waste ferrite-calcium slag Waste from the processing of copper-zinc concentrates, light-gray material, Storage sand. Size modulus 0.89: bulk density 1225g-2000 kg / m; true density is 3.52-4.40 g / cm. The main mineral of ferrite-calcium slag is dicalcium silicate, classified as YCj, S.

  The clay components of the Mitrofanovskoye deposit are moderate plastic, refractory, coarsely dispersed, the clay of the Tagansky deposit is highly plastic with a plasticity number of 40-60, as well as window and bottle glass and volastonite of the Khairuzovsky deposit.

The chemical composition of the initial components is given in Table 1,

The use of a combined sintering intensifier made of ferrite-calcium slag and broken glass at the specified ratio of components allows to obtain high-quality ceramic paste for the manufacture of facade and facing tiles at -10 high-speed firing modes and maximum temperatures not exceeding 980-1000 ° C.

The mass is prepared as follows.

Co-milling of all components 15 is carried out using the dry method in a laboratory ball mill until the residue on sieve No. 005 is 4-6%. Dissolution of clay and mixing of emaciated components is performed in a mixer with a humidity of 20–50-55%. The prepared mass is dehydrated and dried. Press powder is prepared with a moisture content of 6-8%. The tiles are pressed at 980-1000 ° C. Roasting time 8-12 min.

Composites: you are ceramic masses for the manufacture of facade and facing tiles in Table 2.

The results of physico-mechanical tests are given in tab. Table 1 .
