Effect of Density and Ambient Temperature on Coefficient of Thermal Conductivity of Heat-Insulated EPS and PU Materials for Food Packaging SONG Haiyana, CHENG Xinxinb and CHU Leic College of Packaging & Printing Engineering, Tianjin University of Science & Technology, Tianjin, China ahysong@tust.edu.cn, bchengxin2009.cool@163.com, cby_chulei@126.com Keywords: Coefficient of thermal conductivity; Heat-insulated material; Density; Ambient temperature Abstract.
In order to provide theoretical reference basis for the selection of heat-insulated materials, we test the coefficient of thermal conductivity of polystyrene foamed plastic (EPS) and rigid polyurethane foam plastic (PU) in different densities at different ambient temperatures, and then determine the effect of material density and ambient temperature on the coefficient of thermal conductivity of food insulation packaging materials.

Impact of pH Value and Temperature on Cement-based Materials Adsorbing Heavy Metal Ions Yali Wanga*, Suping Cuib, Xikui Xuc, Mingzhang Land College of Materials Science and Engineering, Beijing University of Technology, 100 Pingleyuan, Chaoyang District, Beijing 100124, China.
Micro-structure analysis shows that cement-based materials’ main adsorption methods are different when pH values are different.
Permeable pavement materials can discharge the rainwater very fast and prevent surface accumulated water.
Summary Cement-based materials have selective adsorption phenomenon for different heavy metal ions (Cu2+, Zn2+, Pb2+, Cd2+).In addition to zinc ions, the cement-based materials’ capacity of adsorbing heavy metal ions increases as the pH value and the temperature increase.
