METHOD OF MANUFACTURING HEAT INSULATION Russian patent published in 1994 - IPC

Abstract RU 2012546 C1

FIELD: manufacturing heat insulation. SUBSTANCE: composition of the base of acetone-formaldehyde resin is spread into hole construction of cold insulating device to froth. Inside walls of said device are preliminary covered by damping material of fine-mesh polyurethane or by glass wool mats of perforated paper. Thus produced heat insulation has: volume mass 230-240 kg/m², coefficient of heat conductivity 0.028-0.029 W/mK. EFFECT: improves efficiency of the method. 1 tbl
