Properties of thermal insulation materials - part 2
The properties of insulation materials include thermophysical and mechanical properties. Achieving high efficiency and saving materials requires a deep understanding of the properties of insulation materials in the process of optimal design of cover structures or insulation layers for thermal equipment and plants.
In part 1, we learned that in the heat transfer process there are 3 decisive factors: thermal conductivity, thermal conductivity and specific heat capacity. These are important thermal and physical properties of insulation materials. Achieving high efficiency and saving materials requires a deep understanding of these factors in the process of optimal design of the cover structure or insulation layer for thermal equipment and plants.
Following part 2, we will consider some remaining thermophysical properties of insulation materials.
Maximum temperature.
The maximum temperature is the critical temperature allowed under the conditions of long-term use of insulation materials. The maximum temperature is usually lower than the temperature resistance of the material. When deciding on the maximum we need to consider the possibility of damage that occurs while the material is heated for long periods of time. In glass structures such as mineral wool or glass wool, when heated for a long time, destruction of the material structure can occur.
For insulation materials produced from organic materials (wood panels, peat, etc.), the maximum temperature is also determined based on the flammability factor of the product during the process. usage process. Normally, factories often add fire retardant additives to increase the ignition temperature of the material.
