一种新型高效多层绝热系统(GS—80多层绝热系统)的研制

研制出一种高效多层绝热系统(GS-80多层绝热系统)。该材料系以涤纶薄膜为基体,一面镀铝,作为反射屏。另一面涂以热导系数小的粒状无机物,作为屏间隔层。粒状间隔层对提高系统的绝热性能有良好的效果。这种材料除能用以绕制高效绝热系统外,还有强度高、重量轻(每平方米约14克左右)、厚度薄(每层约20-40微米)、耐振动、质地柔软,使用方便等优点。测量了用这种材料绕制成的多层绝热系统的热传递性能,并对得到的结果进行了分析。

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.
