AbstractAbout AuthorsReferences
In this article, the general information about aerogels as well as application areas of materials based on them are presented. Scientific and technical review on heat conductivity of aerogel-based thermal insulation materials was made. It was determined, that among the Russian studies the results of behaviour of these materials under high temperatures are not presented. Comprehensive studies of thermal characteristics, including heat conductivity values in temperature range of 10–650оС (where 650оС is the maximal operating temperature) for the thermal insulation rolled materials based on SiO2-aerogel DRT06-Z (Alison Aerogel) were carried out. The mathematical relationship between heat conductivity and operating temperature in range of 10–650оС was determined. Using the obtained results, the calculation of thickness of insulation for the studied aerogel-based rolled materials was realized according to the construction rules SP 61.13330.2010, that can be applied for design of high-heat insulation for equipment and pipelines.
