Description

one

The invention is fireproof for the glass of glass used as powdered colored powders of molded or ingrosted finishing of building products and structures, as well as for the manufacture of facing materials based on a polymer matrix.

In the manufacture of this glass, a ferroslag of ferrochromic production is used as a raw material, which {GM 24 is prepared as a raw material mixture for low-melting glass, consisting of sand, water, limestone. Glasses from light green EU emerald green & veta with a density of 2.00 to 2.7 g / cm are obtained; according to their chemical value, the glass bones belong to the third index. the rolitic class (the material of the indicated composition is obtained by discharging melted, molten glass into).

Glasses of this composition have a disadvantage due to their low density and do not meet the requirements of eduction during external facing of surfaces.

The most popular in composition is glass for the manufacture of colored powder G2, comprising, in weight%:

The powder has a bright tone and is used for the manufacture of monolithic coatings and as a filler. The purpose of the invention is to reduce the glass melting temperature. This goal is achieved by the fact that glass for making color powder, including iO /, CaO,, ft arjp, FeijOg, contains in addition the .11 at the following ratio of components, wt.%: 5i Oij25-35 CaO26-38 I.,.

Examples of compositions and technological parameters of their training are given in table. 1. Table I

In tab. Table 2 shows the values of resistance, frost resistance, water, absorption and density, and such cover. As can be seen from Table 2, the values of chemical resistance, frost resistance, water accumulation and density are quite high and meet the operational requirements at atmospheric exposure.

Glass brewing can be carried out in baths of periodic and continuous scale, as well as in pot furnaces. Cooking temperature is 950 ° C. OIMAL RESISTANCE glass belongs to hydrolytic class 1-2. Colored glass is prepared by pellets by pre-rolling molten glass and followed by a rare thermal shock - treatment with holoz water. Increased chemical resistance. chalet density, frost resistance. Water absorption involves using & powders in alkaline media, for example, as a filler in decorative mortars and concretes. Color colored powder ifs in the glass of Mo: kHo can also be used as a textured decorative material for exterior and exterior decoration of buildings and structures.
