Description

one

The invention relates to glass compositions and can be used in the glass industry to produce slagositall and marblit glass.

Known glass for producing slakositall and marbite. It contains SiO2, ABOz, CaO, MgO, RegOz + PEO, MpO and RaO.

In order to increase the wear resistance of the proposed glass contains these components in the following, their quantities, wt.%:

SiOa

37-52

ABOZ 2-11

19-30

CaO 1 - 10

MgO

10-18

RegOz + ReO

MPO 3-6 2-5,

Na2O

moreover, the components of MnO and (Fe2O3 + PeO) are in a ratio of 1: 3.

The introduction of the components Si02, (ReaOz- -ReEO) and MpO in the indicated ratios allows to obtain glass and, on its basis, a slacocitall with a single-crystal phase, together with high durability of the material, and also to use cheap raw materials in the form of various slags and sol. During the heat treatment of the original glass, a monomineralic crystalline phase is formed in the form of pyroxene solid solutions of diopside henbergite

p yes In this case, almost all sladyusha, s glass oxides participate in the formation of the structure of the material, forming a single crystalline compound, poorly defective in physical structure, which leads to high chemical and mechanical durability of slakositall. The fine crystalline structure is characterized by a 9: I crystalline and vitreous phase ratio.

and the size of the crystals is 0.1-0.4 microns. The use of industrial waste as a glass material with a small number of additives, as well as the use of high-performance glass production technology

slakositallov is economically profitable, significantly increases the technical efficiency of the production of building materials.

Glasses of compositions and 2 are characterized by high technological qualities of glass mass. The cooking temperature of these glasses is relatively low (to known building glasses) - 1400-1420 ° C. Glass for

hours are boiled and become homogeneous structure. The melts of these glasses are formed by methods of pressing and pressing, as well as rolling. These black novla glasses are recommended to obtain

various products of wide construction.

ly glass crystal structure with high durability and wear resistance.

Table 5 Glasses of compositions 5 and 6 have high Baroque, working and crystallization properties. The cooking temperature of these glasses is not more than 1420 ° C, and the temperature of the catalysis is 960 ° C. Fine-crystalline slagoscats; the structure of myomineral composition in the form of pyroxeic diopsy solid solutions; | , hedenbergite series, have a characteristic structure of the unrugus. Similar structures are distinguished by a high content of the crispy phase, with the result that glass 1: flat layers, less durable, reduced to: P11I1mum. Crystals grown directly from the mother glass melt have a small size and defect-free structure. Therefore, Shlakositalla and have high wear resistance and durability. The results of measuring the wear resistance of 1 m lacosital are given in Table. 4 Table 4

Steelmaking, blast-furnace slags, slags and ashes of the energy industry, chemical production wastes are used to obtain marblite and slagositalla.
