Description
В р де отраслей промышленности, например в стекольной, фарфоро-фа нсовой и других, совершенно необходимо применение кварцесодержаш ,их материалов (песка, песчаника, кварц {та), свободных от примесей соединений железа. Так, дл получени большинства стеклоизделий требуетс песок, совершенно не содержащий окислов железа, или имеющий весьма незначительные примеси их.In a number of industries, for example, in glass, porcelain-fass and others, it is absolutely necessary to use quartz-containing materials, their materials (sand, sandstone, quartz (m)), free from impurities iron compounds. Thus, to obtain most glass products, sand is required that does not contain iron oxides at all or has very minor impurities.
Присутствие со-единепий железа в песке, идущем дл изготовлени стекла, обуславливает образование в стекле в процессе его варки различных силикатов железа, которые придают стеклу окраску от желтозеленой до сине-зеленой, что портит внешний вид стеклоизделий, а также пОНижает прозрачность стекла и его способность пропускать биологически активные ультрафиолетовые лучи, повышает теплопрозрачность стекла и т. п.The presence of iron compounds in the sand, which is used for making glass, causes the formation of various iron silicates in the glass during its boiling process, which give the glass a color from yellow green to blue-green, which spoils the appearance of glass products, and also lowers the transparency of the glass and its ability transmit biologically active ultraviolet rays, increases the heat transparency of glass, etc.
Описываемый способ дает возможность резко сократить содержание окислов железа в кварцевых песках, что достигаетс следующим образом.The described method makes it possible to drastically reduce the content of iron oxides in quartz sand, which is achieved as follows.
Кварцевый песок, загр зненный окислами железа и обычно имеюЩ .ИЙ желтый цвет, смачивают слабым раствором натриевого жидкого стекла (уд. вес 1,2-1,25), вз тым в количестве 10-15% от веса песка. Затем смесь тщательно перемешивают, после чего ее прокаливают в течение двух-трех часов при температуре 900-950°.Silica sand, contaminated with iron oxides and usually yellow, is moistened with a weak solution of sodium liquid glass (specific weight 1.2-1.25) taken in an amount of 10-15% by weight of sand. Then the mixture is thoroughly mixed, after which it is calcined for two to three hours at a temperature of 900-950 °.
Предмет изобретени Subject invention
Способ удалени окислов железа из кварцевых песков, о тли ч ающийс тем, что кварцевый песок смачивают раствором натриевого жидкого стекла удельного веса 1,2-1.25 в количестве 10-15% от веса песка и после тщательного перемещивани прокаливают при температуре 900-950° в течение 2-3 часов.The method of removing iron oxides from quartz sands, aphids, is moistened with quartz sand with a solution of sodium liquid glass with a specific gravity of 1.2-1.25 in an amount of 10-15% of the weight of sand and, after careful movement, is calcined at a temperature of 900-950 ° C. within 2-3 hours.
