Description

Изобретение относится к области технологии силикатов и касается производства стекла, которое может быть использовано для изготовления изделий декоративно-художественного назначения.The invention relates to the field of technology of silicates and for the production of glass, which can be used for the manufacture of decorative and artistic products.

Известна шихта для получения цветного стекла, включающая, мас.%: сода 5,0-20,0, кварцевый песок 30,0-80,0; окрашивающая добавка 0,01-8,0 [1].A known mixture for producing colored glass, including, wt.%: Soda 5,0-20,0, quartz sand 30,0-80,0; coloring additive 0.01-8.0 [1].

Задачей изобретения является обеспечение безопасности технологического процесса получения цветного стекла, утилизация промышленных отходов.The objective of the invention is to ensure the safety of the process for producing colored glass, the disposal of industrial waste.

Технический результат достигается тем, что шихта для получения цветного стекла, содержащая соду, кварцевый песок, окрашивающую добавку, в качестве окрашивающей добавки содержит высушенный хромосодержащий шлам следующего среднего состава, мас.%: CrO3 общий - 9,8; CrO3 водорастворимый - 3,4; CrO3 кислоторастворимый - 1,6; CaO акт. - 2,37; CaO общ. - 21,4; MgO - 35,7; Fe2O3 - 19,2; Al2O3 - 2,85; SiO2 - 4,8; остальное - вода, и дополнительно - техническую серу при следующем соотношении компонентов, мас.%: сода 15,0-20,0; кварцевый песок 54,5-64,5; указанный высушенный хромосодержащий шлам 20,0-25,0; техническая сера 0,2-0,5.The technical result is achieved in that the mixture for producing colored glass containing soda, quartz sand, a coloring additive, as a coloring additive contains dried chromium-containing sludge of the following average composition, wt.%: CrO 3 total - 9.8; CrO 3 water soluble - 3.4; CrO 3 acid soluble - 1.6; CaO act. - 2.37; CaO total - 21.4; MgO - 35.7; Fe 2 O 3 - 19.2; Al 2 O 3 - 2.85; SiO 2 - 4.8; the rest is water, and additionally, technical sulfur in the following ratio of components, wt.%: soda 15.0-20.0; quartz sand 54.5-64.5; the specified dried chromium-containing sludge 20,0-25,0; technical sulfur 0.2-0.5.

В таблице приведены составы шихты.The table shows the composition of the charge.

Используемая в составе шихты сера восстанавливает токсичный хром (VI), содержащийся в шламе, в стабильный хром (III).Sulfur used in the mixture reduces toxic chromium (VI) contained in the sludge to stable chromium (III).

Стекло может быть получено в электропечах при температуре ~1400°C в окислительной среде. Окраска стекла - от различных оттенков зеленого до коричневого.Glass can be obtained in electric furnaces at a temperature of ~ 1400 ° C in an oxidizing environment. The color of the glass is from various shades of green to brown.
