Low-vacuum Thermal Insulation Panels based on Silicon Dioxide Powders
School of Engineering and Construction, Siberian Federal University, 82 Svobodny, Krasnoyarsk, 660041 Russia
The composition and technology of obtaining low-vacuum thermal insulation panels with a powder filler of silicon dioxide and infrared silencer have been developed. The thermal conductivity of the low vacuum insulated products with the use of synthetic silica dioxide and micro-silica - waste production with the addition of titanium dioxide at moderate temperatures with samples of 37.5°C and 1.0°C is investigated. The results of electron microscopy of materials studied are presented. The optimal amount of additive-infrared silencer is determined. It has been found out that low-vacuum products based on micro-silica with an optimal amount of additives have a thermal conductivity lower than that of the air at lower temperatures.
