Description
Изобретение относитс к производству строительных материалов и может быть использовано дл получени пористых -изделий с применением отходов переработки слюд ного сырь при извлечении редких металлов.The invention relates to the production of building materials and can be used to obtain porous products using waste mica raw materials in the extraction of rare metals.
Цель изобретени - снижение стоимости изделий и упрощение технологии изготовлени .The purpose of the invention is to reduce the cost of products and simplify manufacturing technology.
Остаточный продукт серно- кислот- ной обработки слоистых алюмосиликатов образуетс в виде отхода в результате обработки кислотой слюд ного сьфь при извлечении редких металлов.The residual product of sulfuric acid treatment of layered aluminosilicates is formed as a waste as a result of mica treatment with acid when extracting rare metals.
Пример. Дл получени пористых изделий используют остаточный продукт серно-кислотной обработки вермикулита следующего химического состава,%: SiOi 78,76; Fe,0j 0,08; CaO 0,11; MgO 0,20;NaiO U,01 KjO 0,05; 13,56; ,90; COj., COj и AE-jOj не обнаружено. Продукт представлен рентгеноаморфной псевдослюдой состава , содержит активный слоистый кремнезем, имеет насыпную массу до 0,2 г/см и характеризуетс высокой дисперсностью (до 600 м /г) по удельной поверхности . Этот продукт смешивают с природным кварцевым песком и цементом, а затем обрабатывают водным растворомExample. To obtain porous products, the residual product of sulfuric acid vermiculite treatment of the following chemical composition is used,%: SiOi 78.76; Fe, 0j 0.08; CaO 0.11; MgO 0.20; NaiO U, 01 KjO 0.05; 13.56; , 90; COj., COj and AE-jOj not detected. The product is represented by an x-ray amorphous pseudo-mica composition, contains active layered silica, has a bulk density of up to 0.2 g / cm and is characterized by high dispersion (up to 600 m / g) over specific surface. This product is mixed with natural quartz sand and cement, and then treated with an aqueous solution.
