Теплоизоляционные силикатные высокопористые материалы, формируемые с использованием термического нагрева и микроволнового излучения

Abstract

The method of new heat-insulating foamed silicate materials preparation was developed. Heat-insulating materials have high porosity and, consequently, low average density and heat conductivity. The mechanical-and-physical properties are following: apparent density 250-300 kg/m3, ccompression breakdown strength 0,15-1,40 mPA, cconductivity factor 0,08-0,035 Wt/m*K.The preliminary experiments on microwave energy using for preparation foamed silicate materials were realized. Heat-insulating materials are intended for insulation of buddings and technical constructions in the temperatures -50 to 600 °C.
