Description

(.54) CERAMIC MASS

The invention relates to building ceramics, primarily to the manufacture of metlakh tiles.

Ceramic mass for making tiles tlT / including the following components, wt%: Known mineral powders having a refractoriness temperature less than 1200 ° C 3-10

ClayE rest

The disadvantage of this mass composition is the production of products with relatively high water absorption rates,

Ceramic mass 21 is closest to the invention, including the following components. weight.%:

Clay refractory 80-85 Clay shales - mining waste. 15-20 The disadvantage of this mass composition is the high water absorption of the products.

The aim of the invention is to reduce the water absorption of the tiles.

This goal is achieved by the fact that the ceramic mass, predominant for the manufacture of metal slabs, including clay, refractory and mining waste, contains waste from the mining of bauxite or ferruginous quartzite as mining waste, in wt.%:

ten

Clay refractory 70-80

Waste generated by

bauxite mining or

ferruginous quartzite 20-30

The chemical composition of the original components is given in Table. one.

Clay belongs to the group of basic clay raw materials, is medium-plastic and medium-seamed. From 20 courses obtained in the extraction of bauxite and ferruginous quartzite - a rock of shale texture that does not wash out in water, and has a pelitomorphic microlepidogranoblastic structure of kaolin and hydromica of that composition. Products made by the following technology. After wet grinding of the starting components in a ball mill for 1 h, the slip is dehydrated in a drying cabinet

30 at 105-110 ° C and press press box is prepared

humidity 7%. The tiles are molded in me. As can be seen from the data presented, the shape of the tile is sized. mm, the use of the mass offered is dried at room temperature, the composition reduces the water absorption in the drying cabinet, the application of ceramic products, the OS-IIO C utility and is burned in silicon to heat the waste produced by dop-lOSO-IIOO C. 5 more bauxite and ferruginous (51 x quartzite,
