Description

The invention belongs to the chemical industry, namely to the production of narrow-necked and wide-necked glass containers for the beer, liquor-vodka and wine industries from semi-white (mainly to dark green and dark green-brown (bOeaav Iveai and Sime) tones.

Different compositions of glass for glass containers are known, including the following components: 5iO»2, AIg2Oz, HegOz, Cao,

Mao, Mago, KO, 50", Si2Oz ||, which differ slightly from each other in terms of the quantitative composition of the components included in them. However, these minor differences form the composition of glass, the physical and technological properties of which differ significantly from the characteristics of other compositions.

Glass for glass containers, including components, wt. because: BIO" 71.50-73.50; AI2Oz 1.00-2.10; HegOz 0.20-0.50; СаО 10.00-12.00; MoO 0.50-1.00; MagO 12.30-13.50; KgO 0.01-0.15; TiO" 0.05-0.20; MPO 0.01-0.10; 5 Oz 0.10-0.30; Cg2Oz 0.21-0.25 with a ratio of BeO/Beg2Oz3-0.21 is the closest analogue of the present invention |2)1. The disadvantage of this composition is low indicators of heat resistance, "color tone" and "color purity" when painting glass in tones from semi-white (na!lYaipO) to dark green-brown (beavy Ieai and Simee).

The problem solved by the claimed invention is to increase the heat resistance of glass (the ability of glass to withstand sudden temperature changes (thermal shocks) without destruction), increase the strength properties of glass, improve the "color background", "color purity", ensuring the preservation of the contents of the container glass.

The essence of the invention is that container glass containing 5iOg, Alg6Oz, BegOz, CaO, MOO,

MagO, K2O, TiO", Mpo, EeO, 50", Si2Oz, the ratio of EBeO/RegOz is 0.28-0.39, contains components in this ratio, wt. because: 5iOg 70.047-71.72; Ag2Oz 1.37-1.98; BegOz 0.328-0.691; CaO 7.878-10.92; ModO 3.01-3.328; MagO 12.46-14.04; KO 0.15-0.92; TO" 0.001-0.055; MPO 0.001-0.015; BeO 0.092-0.264; 5 Oz 0.027-0.053; St2Oz 0.1198-0.170.

The technical result of the invention consists in increasing the heat resistance of container glass, increasing the parameters of "color tone" and "color purity" when painting glass in tones from semi-white (Naye

Type) to dark green and dark green-brown (Oeai Ieaigii and Simee) and ensuring the preservation of the contents of the vessel from the proposed container glass.

Correlation

The effect of changing the amount of ReO and RegOz and their ratio on increasing the heat resistance of glass is presented in the table below.

The properties of the proposed container glass compositions are presented in Table 2.

The analysis of the presented data shows that an increase in the content of GeO and RegOz in the composition of container glass leads to an increase in thermal resistance, so with a content of GeO - 0.092 and RegOz - 0.328 (the BeO/RegOz ratio is 0.28) at 45" 1 bottle out of 2 is destroyed; at 75" - From a bottle of 4 (Mo composition 1), and with a content of BeO - 0.24-0.264 and Regbz - 0.603-0.691 (ratio

EeO/EegOz is 0.38-0.39) (compositions Mo 3 and Mo 4), both at 45" and at 75" all tested bottles from the proposed container glass showed high heat resistance - no damage was detected.

When the content of these oxides in the container glass is increased, the heat transfer decreases and the thermal conductivity of the glass increases, which is manifested by an increase in heat resistance at high temperatures and the ability of the glass to withstand sharp temperature changes (thermal shocks) without collapsing.

The study of the dependence of light transmittance on changes in the content of these oxides and their ratio revealed an inverse relationship: the higher their content in the container glass, respectively, the BeO/Be2Oz ratio, the lower the light transmittance. Light transmission indicators are important for the contents of the bottle - low light transmission has a positive effect on ensuring the preservation of the contents of the container made of the proposed container glass.

The following raw materials are used to prepare the charge: quartz sand, soda ash, alumina, gypsum, limestone, carbon, portachrome SggOz, portafer (BegOz--Eed).

In order to save expensive materials (alumina, quartz sand, magnesium oxide, portafer, potassium nitrate, etc.), in the technology of manufacturing container glass, there is an option to prepare the charge using waste products from basalt, wt. 96: 5iOg" 48.8; AI29Oz 15.0; Reg2Hoz 8,47; СаО 8.34; MoO 5.13; MagO 1.5; K2O 0.75; Be 6,39; TiO" 2.75.

In this case, waste from the production of basalt products with a particle size of 0.3-3 mm is added to the charge, subjected to the melting mode with the help of microprocessors, in which the components included in the glass are in the range of compositions of the proposed invention. From the comparison of glass and basalt, it follows that all the constituent ingredients of synthetic glass, with the exception of

Si2O»z, completely or partially introduced by natural basalt.

The charge and waste from the production of basalt products are fed into a continuous glass furnace.

The temperature in the maximum zone of the glass-making furnace should not be lower than 1580 "C. From the glass-making furnace, special feeders (drop type) ensure the supply of portions of the glass mass for forming to the glass-forming machines.

The charge for obtaining container glass includes the following materials (kg): quartz sand - 1560.00; soda ash - 495.00; alumina - 24.00; gypsum - 7.00; limestone - 420; carbon - 3.00; portachrome - 5.59; waste from the production of basalt products with particle sizes of 0.3-3 mm.

Molded glass products are subject to automatic control, where low-quality products are rejected, and quality products are packed and transported to the finished goods warehouse.

Laboratory melting and industrial tests have shown the possibility of obtaining container glass with increased heat resistance from the proposed compositions and from semi-white (Naii Pp) to dark green and dark green-brown bOeav Iveyai and Simeya) tones with uniform intense coloring.

The use of the proposed container glass compositions allows to improve the quality of products in the glass industry, reduce production costs, expand the raw material base of materials used in the glass industry, and ensure the preservation of the contents of the container made of the proposed container glass.
