Heat-shielding properties of heat-insulating materials under conditions of wetting-drying cycles
Incoming article date: 28.03.2023Insulating materials are widely used in the petrochemical, energy and other industries. Thermal insulation materials play an important role in the energy saving of district heating systems and in the construction sector. In this work, the influence of the wetting and drying cycle on the thermal conductivity and density of the heat-insulating material is determined by the experimental method. The thermal conductivity of the insulating material was determined by the protected hot plate method. It has been established that after four cycles of wetting and drying, the thermal conductivity and density of the heat-insulating material increase up to 2 and 2.5 times, respectively.
Keywords: thermal conductivity of heat-insulating materials, density of heat-insulating materials, dampening of heat-insulating materials
