Использование: производство стеновых керамических изделий, преимущественно кирпича. Сущность: способ включает совместный помол глинистого сланца и перлита, или обсидиана, или стеклобой до дисперсности 50 - 600 мкм, перемешивание с добавлением негашеной извести, увлажнение 5 - 10%-ным водным раствором едкого натра до получения композиции состава, мас.%: глинистый сланец - 60 - 80, перлит или обсидиан - 15 - 20, или стеклобой - 5 - 20, негашеная известь - 5 - 10, едкий натр - 5 - 10, прессование заготовок, сушку и обжиг путем нагрева до максимальной температуры 750 - 800°С со скоростью 200 - 300°С в ч с последующей выдержкой в течение 1 - 3 ч. При этом формование можно проводить методом полусухого прессования при удельном давлении 15 - 20 МПа и сушить заготовки до влажности менее 1%. Физико-механические показатели : водопоглощение 2,1 - 10%, морозостойкость 25 - 50 циклов, предел прочности при сжатии 22 - 45 МПа, при изгибе 2 - 4 МПа, цвет от желтого до красно-коричневого.Use: manufacture of wall ceramic products, mainly bricks. Essence: the method includes the joint grinding of shale and perlite, or obsidian, or broken glass to a dispersion of 50-600 microns, mixing with the addition of quicklime, moistening with 5-10% aqueous caustic soda to obtain the composition, wt.%: Clay slate - 60 - 80, perlite or obsidian - 15 - 20, or broken glass - 5 - 20, quicklime - 5 - 10, caustic soda - 5 - 10, pressing blanks, drying and firing by heating to a maximum temperature of 750 - 800 ° C at a speed of 200 - 300 ° C per hour, followed by exposure for 1 to 3 hours. At the same time, molding can be carried out by the method of semi-dry pressing at a specific pressure of 15-20 MPa and drying the workpiece to a moisture content of less than 1%. Physical and mechanical properties: water absorption 2.1 - 10%, frost resistance 25 - 50 cycles, compressive strength 22 - 45 MPa, bending 2 - 4 MPa, color from yellow to red-brown.
