Description
まず、図1を参照して説明したガラス繊維ボードを10×300×400mm(厚さ×幅×長さ)の大きさに製造した後、1〜3枚を積層して芯材を形成した。
10×300×400mm(厚さ×幅×長さ)のバインダーグラスウールタイプのガラス繊維ボードを製造した後、1〜3枚を積層して芯材を形成した。
図1を参照して説明したガラス繊維ボードを10×300×400mm(厚さ×幅×長さ)の大きさに製造した後、1〜3枚を積層して芯材を形成した。
図1を参照して説明したガラス繊維ボードを10×300×400mm(厚さ×幅×長さ)の大きさに製造した後、1〜3枚を積層して芯材を形成した。
上述した実施例及び比較例に係る真空断熱パネルを85℃の恒温チャンバにそれぞれ入れて10日間維持しながら、全体加熱を実施していないものと熱伝導率を比較した。このとき、熱伝導率の測定にはHC―074・300(英弘精機株式会社製)熱伝導測定器を使用した。次に、加速ファクターを適用して0〜10年までの熱伝導率を予測し、その結果を下記の表1及び図7に示した。
