Simple Measurement of Conductivity of Colored Acrylic Sheets

Abstract

In many applications, colored acrylic sheets require information on thermal conductivity values. However, thermal conductivity data has not been found in the literature and research publications, especially colored acrylic sheets. The purpose of this study was to investigate the heat conductivity value of colored acrylic sheets including transparent, cloudy, white, black, green and blue colors found in the market. This research was done with the experimental method of measuring the thermal conductivity of colored acrylic in a closed room four rectangles 80 cm x 40 cm x 40cm of 9 mm plywood coated with black paper and divided into two compartments and test material 40 cm x 40 cm x 0.3cm as patisi room. The heat source used is a 75watt incandescent lamp placed on one side of the room. Acrylic thermal conductivity is calculated based on temperature data at each measurement point reaching a steady state which is obtained at the 30th minute and taking into account the convection heat and air radiation in the test chamber. The results showed that pigment additives greatly affect the thermal conductivity value of acrylic and its value is lower than the conductivity value of acrylic colorless sheet transfaran.
