Description
перлита, с последующей промывкой полученного кауетифицированного продукта до содержани в нем щелочи 0,5-1,0 вес. % по NaaO.perlite, followed by washing of the obtained caourified product to its alkali content 0.5-1.0 wt. % NaaO.
Предложенный способ обеспечивает повыщение выхода целевого продукта по диопсиду до 98% и его дисперсности до 6,0- 11,5 при существенной интенсификации процесса в pёзyЛьtaтe сокращени его продолЖительности до 0,5-1 ч.The proposed method provides an increase in the yield of the target product by diopside up to 98% and its dispersion to 6.0- 11.5, with a significant intensification of the process during the reduction of its duration to 0.5-1 h.
Пример 1. 10 л щелочно-кремнеземистого раствора, содержащего 80 г/л NazO-f+К2О и 60 г/л SiOa, подогревают в реакторе до 80°С, добавл ют в него 500 г обожженного доломита с содержанием СаО и MgO 87%, перемещивают в течение часа и фильтруют. Образовавщийс осадок промывают теплой водой до содержани 0,5 вес. % NagO, а затем прокаливают при 1000°С в течение одного часа.Example 1. 10 l of an alkaline-silica solution containing 80 g / l of NazO-f + K2O and 60 g / l of SiOa are heated in the reactor to 80 ° C, 500 g of calcined dolomite with 87% CaO and MgO content are added to it Move for an hour and filter. The precipitate formed is washed with warm water to a content of 0.5 wt. % NagO, and then calcined at 1000 ° C for one hour.
Полученный продукт содержит 98% диопсида и имеет удельную поверхность 10 . При следующем процентном распределении частиц в микронах; 100-40 мк- 15%, 40--10 мк -75%, 10-1 мк -9,0% и 1 мк-1,0%.The resulting product contains 98% diopside and has a specific surface area of 10. With the next percentage distribution of particles in microns; 100-40 microns - 15%, 40--10 microns -75%, 10-1 microns -9.0% and 1 microns-1.0%.
При мер. 2. Осадок кальций-магниевого гидросиликата, полученный аналогично примеру 1 каустификацией щелочного-кремнеземистого раствора, промывают до содержани в нем 1,0 вес. % NagO, а затем прокаливают при 900°С в течение часа.For example. 2. The precipitate of calcium-magnesium hydrosilicate, obtained analogously to example 1 by caustification of an alkaline-silica solution, is washed to contain 1.0 weight. % NagO, and then calcined at 900 ° C for one hour.
Получают продукт с 98%-ным содержанием диопсида и с удельной поверхностью 11,5м2/г.A product is obtained with a 98% content of diopside and with a specific surface of 11.5 m2 / g.
Способ получени синтетического диопсида согласно данному изобретению достаточно экономичен, так как позвол ет снизить энер ётйч:еСйие затраты за счет снижени температур обжига и производительности последнего.The method for producing synthetic diopside according to the present invention is quite economical, since it allows one to reduce energy efficiency: the cost by reducing the firing temperature and the productivity of the latter.
Кроме того, повыщенна дисперсность и больщее содержание в целевом продукте диопсида улучщает его качество и расщир ет возможность его использовани в различных композиционных материалах.In addition, the increased dispersion and higher content of diopside in the target product improves its quality and facilitates its use in various composite materials.
