3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 4132 and GB/T 5480 and the following apply.
3.1
aerogel
a kind of nanoporous solid material made by sol-gel method and dried by a method in which the liquid component of the gel has been replaced with a gas
3.2
reinforced nanoporous aerogel products for thermal insulation
nanoporous composite product made by sol-gel method to compsite with reinforced material and dried by a method in which the liquid component of the gel has been replaced with a gas
3.3
resilience rate
the recovery property of aerogel blanket which is compressed under certain pressure for a period of time. It is indicated by a ratio between the recovered thickness after unloading and the original thickness
