Research of Thermophysical Properties of the Ultrathin Liquid Heat-Insulation

Article Preview

Abstract:

The article highlights the results of the study of thermophysical properties of ultrathin liquid insulation when used to protect steel elements embedded in a multilayer outer wall. Conducted graphical analysis of the problem being solved. The results of temperature calculations with linear thermal properties showed that the unprotected insulation of steel embedded elements may freeze, and the formation of mold on the inner surface of the wall. The use of superfine heat insulation for thermal protection of mortgages of steel elements inside the construction of multilayer exterior walls gives a positive result. As a result of constructive solutions with the use of superfine thermal insulation can increase the average temperature of the inner bearing part of a wall of concrete. In addition, there is also a possibility to increase the temperature on the contact line between steel element with a load-bearing wall of concrete.
