Description

one

The invention relates to a mixture for the preparation of unbaked facing tiles and can find and use in the industry of building materials.

The known charge for the manufacture of body materials, including orthophosphoric acid, aluminum hydroxide, bauxite and clay 1.

Also known is closest to the inventive technical sush.nost and the achieved result of the charge for the manufacture of facing unburned or stock, including, weight. %: clay 20-30, cesok 58.5-60, orthophosphoric acid 16-25; alumina hydrate 5-15 2.

The disadvantages of such formulations are low flexural strength or low bending strength and low frost resistance.

The invention was the highest degree of bending and freeze resistance or current.

This aim is achieved in that the charge for the manufacture bezobzhigovyh tiles, vklyuchayush and clay, sand, and acid ortofosforiuyu alyuminiysoderzhani1n komnonent contains as the aluminum waste komnoneita komnleksa catalytic petrochemical iroizvodstva and further trenel, cinders and lime iiritnye

In order to obtain smooth lining claddings, three compositions of the charge are prepared, given in Table. one.

The mixture is prepared in the following sequence.

Preliminary on the basis of the waste of the catalytic complex and the orthophosphoric

about

acids are prepared in the following way: orthophosphoric acid is heated (100-120 ° C), and then waste from the catalytic complex is introduced into it during mixing. The remaining components of the charge are combined with a bundle. The bond in the charge is introduced in a hot form. Tiles 5X5X0.8 cm in size are pressed on a laboratory pressure at a pressure of 50 kg / cm, and then at a secondary pressure of 180 kg / cm -. To obtain color stains, lngmeites can be introduced into the system while mixing the components of the bird. Next, the lint is dried for 1 hour at 50–70 ° C and subjected to heat treatment at 300–400 ° C for 80–60 million.

For finished tiles, the bulk weight, water absorption, frost resistance, and flexural strength are determined.

The results are given in Table 1. 2

You can make unburned ceramics out of the resulting casting waste containing chemical industry waste products and cheap natural materials);

The optimal amount of orthophosphoric acid is between 12 and 20 wt. % A further increase or decrease in the content of orthophosphoric acid in the charge worsens the physicomechanical characteristics of the sheet.

The recommended composition of the charge to obtain unburned ore-containing or scrap includes waste waste from sulphate production — pyrite ogarn, which contain 60–30% Pe 2 O 3 n, in addition, oxides SiO 2, PbO, ZnO, FeO, CuO. These oxides promote the structure formation and partial curing of the composition at room temperature. The mixture also includes cheap chemical production waste — waste from the catalytic complex of chemical and chemical production, which contain in its composition, weight. %: SiO 7.91; CrHo 15.7; AlgOg 69; CCUz 4.93; FejOs 2.25. .

These oxides, interacting with orthophosphoric acid at 100-120 ° C, form an aluminum-chromophosphoric binder. Tripoli as a cheap natural building material, consisting practically of

The production capacity of the tiles of the proposed charge is increased by 1.5-2 times.
