PREPARATION OF BASALT–CELLULOSE THERMAL INSULATION MATERIALS

Abstract

The advancement of many modern technologies requires the creation of efficient thermal insulation materials. The highest performance has been achieved with multilayer vacuum insulating screens, consisting of thermally separated layers using glass-paper-fiberglass materials as spacers. These materials typically contain 9–18% organic binders to provide mechanical strength. However, such binders reduce insulation efficiency by increasing thermal conductivity and releasing gases that prevent the formation of a high vacuum.
