Description

(Ls

The invention relates to the building materials industry and can be used in the manufacture of protective coatings for dust collecting devices of solid fuel power plants.

The known composition for protection of the hydro ash filter equipment from ash wear, including, wt.%: Liquid glass 40-59, sodium silicofluoride 10-11 and ash. TPPs operating on Ekibastuz coal the rest l.

Closest to the proposed technical essence and the achieved p €; the result is a composition that includes, in wt%: liquid glass 16-27.9; phosphoric slag 3040; ground sand or ash 42-50 and a gasifier (aluminum powder) 0.1-0.8 2.

A disadvantage of the known mixtures is low wear resistance.

The purpose of the invention is to increase wear resistance.

This goal is achieved in that the composition is mainly for protecting the hydrodischarge equipment from ash wear, including liquid glass, phosphoric slag and sand or ash of thermal power plants, contains

these components in the following ratio, wt.%:

Liquid glass 27-32

Phosphorus ass 50-63

Sand or ash CHP5-23

LosFor ;, the first donkey of the Chimkent phosphoric and Temir-Taussky metallurgical plants has the following

chemical composition, wt.%: 39.380 39.85; L22z 9, 71-11, 58; Kg C: 0.592, 17; CaO 43.52-46.36 and I / - - the rest.

Modulus of basicity 0.9-1; activity module 0.3

An example. Liquid glass with a silicate module of 1.881, 89 and a density of 1.355 g / cm, phosphoric slag from Chimkent or Temir-Taussky plants and ash of thermal power plants are used,

working on Ekibastuz coal. These components are prepared for samples that are tested for wear resistance, determined by the rate of abrasive wear (in mm / h)

 and better achievability at different pH.

The table shows the compositions and test results of the proposed and known compositions.
