VACUUM HEAT INSULATION PANEL FOR STRUCTURE
PROBLEM TO BE SOLVED: To suppress increase of heat conductivity within a fixed period right after manufacturing a vacuum heat insulation panel, to maintain excellent heat insulation performance substantially equivalent to heat insulation performance right after manufacturing.SOLUTION: A method for manufacturing a vacuum heat insulation panel comprises wrapping a core material 1 comprising inorganic fibers with an external wrapping material 2 made of a stainless steel plate, and making an internal space 3 of the external wrapping material 2 wrapping the core material 1 into a vacuum state. The method also comprises sealing a peripheral edge part of the external wrapping material 2 with welding in a state where the moisture content contained in the core material 1 is equal to or less than 0.05 wt.%, surface roughness Ra of a surface on an internal space side of the external wrapping material 2 is equal to or less than 0.2 μm, and pressure in the internal space 3 of the external wrapping material 2 is equal to or less than 1 Pa.SELECTED DRAWING: Figure 1
【課題】真空断熱パネルの製造直後から一定期間内の熱伝導率の上昇を抑制することにより、製造直後の断熱性能に近い良好な断熱性能を長期にわたって維持すること。【解決手段】無機繊維からなる芯材１をステンレス鋼板製の外包材２で包み込み、その芯材１を包み込んだ外包材２の内部空間３が真空状態とされた真空断熱パネルを製造する方法であって、当該芯材１が含有する水分量を０．０５重量％以下とし、前記外包材２の内部空間側となる面の表面粗さＲａが０．２μｍ以下であり、外包材２の内部空間３の圧力を１Ｐａ以下とした状態で当該外包材２の周縁部を溶接により封止する。【選択図】図１
