摘要 |
A thermal isolation system of a pipe (10) (figure 1) is claimed. It consists of a sleeve consisting of an aerogel which surrounds at least part of the length of the pipe. The aerogel is made up of a precursor consisting of tetraethylorthosilicate. The thermal isolation process consists of several steps: (a) fabricating of a liquid gel from a precursor and a liquid; (b) substituting the liquid phase by a more volatile solvent; (c) eliminating the solvent in the gel in order to form the aerogel. |
