介绍了低温下真空多层绝热材料导热系数的测试。在相同的条件下对各种材料作了对比试验。结果表明,由233材料(美国产短玻璃纤维纸)组成的绝热体,其绝热性能优于其它材料,特别在低压强下,绝热性能更为显著。图2表1参2。
The test of thermal conductivity of vacuum multi-layer thermal insulation materials at low temperature is introduced. Under the same conditions for a variety of materials made a comparative test. The results show that the adiabatic material consisting of 233 material (short fiberglass paper made in the USA) has better thermal insulation properties than other materials, especially at low pressure.
