A NEW TYPE OF MULTILAYER THERMAL INSULATION SYSTEM WITH HIGH EFFECTIVENESS (GS-80 MULTILAYER INSULATION SYSTEM)

Anew type of multilayer thermal insulation system with high effectiveness (GS-80 multilayer thermal insulation system) was developed.The base material of the insulator is Mylar film.One surface of it is coated with high reflectance aluminium,used as reflective shield,the other surface is painted with stome powdered inorganic material,used as spacer.The powdered spacer can highly increase the thermal performance of the multilayer insulation system.This insulation material has many other advantages such as high strength,small weight (148/m² for each layer) and thickness (20-40μ for each layer),shock resistance,softness and easy to operate.The thermal perfomance of multilayer insulation systems made from this insulation material were measured and the results were analysed.
