Original Abstract
Two different thermal insulating materials based on geocement (formulated as Na2O.Al2O3.6SiO2.20H2O) were produced as possible environmentally friendly materials, to substitute existing thermal insulation of technological equipment. Expanded perlite was added as filler during the mixing process. The two thermal insulating perlite composite materials were produced in the form of two-component mixture with a ratio of liquid phase (geocement dispersion) to solid phase (perlite) of 3:1.8 and 3:1.0. The developed materials are characterized by: compressive strength of 0.11-0.14 MPa; average density of 296-320 kg/m3; thermal conductivity coefficient of 0.068-0.078 W/m.K; adhesion on metal surface of 1.15-1.32 MPa. The measured temperatures on the thermal insulation coatings of technological equipment confirm the effectiveness of the materials developed. These materials, having a thickness not exceeding 3.5 cm, are recommended for application to technological equipment of complex geometric shape at an operating temperature until 1073 K.
