The systems of insulation and a methodology for assessing the durability

Rumiantcev B., Zhukov A., Боброва Е. Ю., Romanova I., Zelenshikov D., Smirnova T.

Formation of effective insulation possible only taking into account features of the insulation layer in the construction and use of high quality materials, preserving their characteristics as in the early stages of operation, and for the entire billing period. The operational stability of the heat-insulating material is determined not only by its properties, but also the ability to withstand long-term operating loads without a significant change in properties. Processing load on the heater may be divided into three groups: the load during transportation and storage, loading and mounting load during operation. Methodology for assessing the properties of insulation products includes two main components: the installation for testing and test methods, as well as the methodology for assessing the operational stability. The methodology of the accelerated testing and forecasting durability tested for mineral wool products laminating, corrugating and volume-oriented structure. The test results give good agreement with the methods recommended by the building codes. Accelerated test plates on the compressibility and compressive strength at 10% deformation after exposure to boiling water over the useful spending for operational control properties of materials, as well as when examining the state of the exploited mineral wool insulation in buildings and heat piping
