Нефелиновый шлам размалывают в вибромельннце до удельной поверхности 4000 .Nepheline mud is ground in a vibrating mill to a specific surface of 4000.
Соду раствор ют в воде при температуре 55-Soda is dissolved in water at a temperature of 55-
60°С.60 ° C.
После смешени компонентов полученную массу прессуют при давлении 200 кгс/см и термообрабатывают в среде перегретого пара при температуре 270±10°С в течение 3 ч. Затем после охлаждени ниже 100°С кирпичи промывают водой и сушат при 100°С.After mixing the components, the resulting mass is pressed at a pressure of 200 kgf / cm and heat treated in an environment of superheated steam at a temperature of 270 ± 10 ° C for 3 hours. After cooling below 100 ° C, the bricks are washed with water and dried at 100 ° C.
Прочность полученного кирпича 170 кг/см. После 60 циклов замораживани и оттаивани потер веса образцов составл ет не более 1%, а прочность кирпича не уменьшаетс , а увеличиваетс на 10-15%. Водопоглош,ение полученного кирпича 9,5%. Исключение автоклавной обработки изделий позвол ет обезопасить и улучшить услови труда, перейти от периодической тепловой обработки в автоклаве к непрерывной.The strength of the resulting brick 170 kg / cm. After 60 cycles of freezing and thawing, the weight loss of the samples is no more than 1%, and the strength of the brick does not decrease, but increases by 10-15%. Water consumption, obtained brick 9.5%. The exclusion of autoclave treatment of products allows to secure and improve working conditions, to move from periodic heat treatment in an autoclave to continuous.
