Preparation of paraffin/expanded perlite composite phase change materials |
| |
| Abstract: | Paraffin/expanded perlite composite phase change material (PCM) was prepared using the method of vacuum absorption and tested by means of differential scanning calorrnetry (DSC) , scanning electron microscopy (SEM) and dif-fused-exudative circle method. The testing results show that paraffin was absorbed into the holes of inorganic carriers completely and distributed evenly with stable performances. It is concluded that the composite PCM has steady tempera-ture-adjust function and the PCM may be applied in building materials. |
