| Title of the article | Research of heat conductivity coefficients of thin layer heat insulators |
| Abstract. | One of the ways of power saving is the reduction of the amount of heat loss from their place of generation to the place of consumption. For this purpose an active search for new high-performance thin-layer thermal insulation materials that meet modern requirements is carried out. Proper and accurate measurement of the thermal conductivity of these materials is of great practical importance, both in the industrial power system, as well as in industrial construction. Experimental setup for the study of thermal conductivity coefficients of one and many layered thin-walled heat-insulators has been designed, implemented and tested. The article describes this installation. For the stationary heat transfer process the thermal heat coefficients have been studied for a package of parallel-sided plates including standard (polyourethanes of various densities, wood along and across the fibber. etc.) as well as the new thin-layers heat-insulators («TSM-Ceramic», «Temp-coat», «JKTM-bronya», «Izollat», «Teplokor» etc). The method of the least squares has been used for the statistical analysis of the research results such as calculation of the standard deviation. absolute value of the maximum deviation. acceptable probability and other statistical characteristics. Evaluation of the measurement’s precision and the resulting experimental data has been conducted. The research results of the study of thermal conductivity coefficients of the thin-layered heat-insulators of the «TSM-Ceramic» (?р ? 0,018 Wt/(m 0С)) type has shown that their values differ by an order of magnitude and more from the advertised values in catalogues and some literature (tsm=0,001 Wt/(m 0С)). |
