<p>PURPOSE: A vacuum insulator with thermal insulation performance and a device using the same are provided to improve absorption ability by adding calcium oxide as an adsorbent material into a binder. CONSTITUTION: A vacuum insulator contains a core material(51) of a fiber assembly, an absorber(54) for absorbing gas, and a coating material(53) receiving the core materials. The absorber includes a synthetic or natural zeolite with alumina and silica as main ingredients and a binder for solidifying the zeolite. The binder includes calcium oxide and content of the calcium oxide is 10.4-16.6 wt%.</p> |
