Description
Дл приготовлени массы обожженную гранитную пыль и известь, вз тые в расчетных количествах, диспергируют при резком охлаждении водой с образованием мелкодисперсной высокоактивной смеси. Измельченную смесь извести и гранитной пыли затем перемешивают с распушенным в воде асбестом до получени устойчивой однородной массы.For the preparation of the mass, the calcined granite dust and lime, taken in calculated amounts, is dispersed under quenching with water to form a fine highly active mixture. The crushed mixture of lime and granite dust is then mixed with fluffed asbestos in water until a stable, uniform mass is obtained.
Асбестосодержащую известково-гранпылевую .массу заливают в формы с припусками на ме.каническую обработку и обрабатывают в среде насыщенного, а затем перегретого пара (11,5-12 ати) до образовани плотного, хорошо закристаллизованного продукта.The asbestos-containing lime-granule mass is poured into molds with allowances for me.canical processing and treated in a medium of saturated and then superheated steam (11.5-12 atm) until a dense, well-crystallized product is formed.
Ниже приведены свойства теплоизол циоппого материала, полученного после гидротермальной обработки и досушки до посто нного веса.The properties of the heat insulating material obtained after hydrothermal treatment and drying to constant weight are given below.
Объемна масса, кг/м 175-200 Bulk weight, kg / m 175-200
Предел прочности при изгибе, кГс/см 4,5-5,5Flexural strength, kg / cm 4.5-5.5
Линейна усадка после обработки при предельной температуре применени 650°С, % 1,5-1,7Linear shrinkage after treatment at the maximum application temperature of 650 ° C,% 1.5-1.7
Предельна температура применени , °С650-670Limit application temperature, ° С650-670
Коэффициент теплопроводности , ккал/м-час °С при 25°С 100°СHeat conductivity coefficient, kcal / m-hour ° С at 25 ° С 100 ° С
Предельна температура применени полученного теплоизол ционного материала выше на 50-70°С, чем у известного. Кроме того, издели из предложенного состава имеют более низкий коэффициент теплопроводности (например , при 25°С 0,048 против 0,05 дл известного состава) и меньшую стоимость (43,5 руб/м вместо 44,3 руб/м).The limiting temperature of application of the heat insulating material obtained is 50-70 ° C higher than that of the known. In addition, the products of the proposed composition have a lower coefficient of thermal conductivity (for example, at 25 ° C 0.048 against 0.05 for a known composition) and lower cost (43.5 rubles / m instead of 44.3 rubles / m).
