| Title of the article | Expanded perlite sand: the modification factors in PVC-compounds |
| Abstract. | The efficiency of modification of rigid PVC-compounds with expanded perlite sand (which is a waste heat shield in cryogenic systems) has been shown. Characteristics of the waste expanded sand such as mineral, fraction and chemical composition is given. The calculation of interfacial layer thickness has been made and change of the properties is being discussed relatively to the interfacial layer structure formation. The increase in thermal stability can be explained as the process of sorption of hydrogen chloride through open porous structure of the grains. In this paper, the influence on the properties of rigid PVC composites expanded perlite sand in the form of waste heat filling cryogenic installations of OJSC «Nizhnekamskneftekhim». Previously identified the effectiveness of the application as filler waste expanded perlite sand in the composition of the PVC-compounds was confirmed and rigid compositions. |
