Description

(S) GLOWED GLASS

one

The invention relates to a glass jerked composition intended for the manufacture of finishing building materials and can be widely used in glass technology.

Known jammed glass, comprising, NaQp, .K, jO, ZnO,, F in the following quantities, weight: SiOrj 62.0-65.0; U, 0-16.0; K (0 5.0–, o 7.0; ZnO 5.0–8.0; ACO 3.2–2.0; F 5.0–6.0. The glass is made of scarce raw material with the introduction of large fluorine amounts 1.

The closest to the invention according to the;, j technical essence and the achieved result is a jammed glass composition, wt.%: SiOi 6,2-72,0; 2.5-6.5; CaO 1,5-, 5; 2.0-13.5, K (2.5-12.0, Liop 0-1.0; 8.03 to 1.520 MgO 1.0-3.0; 9.05-0, t5; (NN4) 0 2 ; F 1.5-5.0.

This glass is a silencer when it is being worked out; it can be used to produce opaque white and painted building materials 2.

The disadvantages of these glasses include low mechanical strength (compressive strength of 800 kgf / cm, flexural strength of 200 kgf / cm) and chemical resistance associated with a high alkali content.

The purpose of the invention is to increase the mechanical strength and chemical resistance of glass.

The goal is achieved by the fact that glass, including SiOij,, Na, jp, KrjO,, .MgO, CaO, F, contains these components in amounts, mas:

Specific glass compositions for glass granules are obtained in the table 1. The required dimensions.

 To obtain jammed glassware, Table 2.

The proposed composition uses a de- s. The proposed glass composition gives scarred non-deficient raw materials - the ability to reduce the cost of odnols, perlite and a small amount of the present-day decrease in toxicity of the soda and sodium fluorosilicate. Stack-melt, as well as increase chemical resistance,

Loss is cast into glass granules, mechanical strength and frost resistance, by sintering and crystallization of 10-bones of decorative facing plates
