MATHEMATICAL CALCULATION AND EXPERIMENTAL INVESTIGATION OF EXPANDED PERLITE BASED HEAT INSULATION MATERIALS’ THERMAL CONDUCTIVITY VALUES

Öz:

Thermal resistance can be increased by using proper heat insulation materials. Traditional heat insulationmaterials do not stand all desired properties. Thus, developing new heat insulation materials is very important. Inthis study, expanded perlite based heat insulation material was developed as an alternative to the traditionalinsulation materials. The composition of the developed material was designed and prepared using the theoreticalthermal conductivity prediction models. The prepared material was molded in a rectangular shape panel. Thermalconductivities of panels were measured experimentally and the results were compared with the calculated results.Also, the results showed that the developed panels can be used for heat insulation applications. On the other hand,the closest model to the experimental results is the parallel model whose average deviation is 4.22% while thefarthest model is the Cheng and Vachon model whose average deviation is 12.43%. It is obtained that parallel andseries models are generally in good agreement with the experimental results. Nevertheless, it is seen somedeviations between experimental and theoretical calculation results. The theoretical prediction models do notinclude any processing conditions such as molding and curing. It is thought that these deviations have originatedbecause of the missing processing parameters in theoretical prediction models. As a result of experimental studies,the lowest thermal conductivity value of expanded perlite based panels was obtained 43.5 mW/m.K. Consequently,the heat transfer coefficient of the panels containing expanded perlite can be calculated nearly by the parallelmethod.
