Abstract

วัสดุฉนวนความร้อนสูญญากาศจะรวมด้วยวัสดุแกนซึ่งยึดที่ว่างสูญกาศ, วัสดุห่อหุ้ม ภายนอกซึ่งหุ้มวัสดุแกน, ชิ้นส่วนดูดซับที่หนึ่งซึ่งรวมด้วยสารดูดซับที่เป็นผงที่หนึ่งและวัสดุห่อหุ้ม ที่หนึ่งซึ่งห่อหุ้มสารดูดซับที่หนึ่งและถูกจัดวางให้สัมผัสกับพื้นผิวด้านในของวัสดุห่อหุ้มภายนอก, และชิ้นส่วนดูดซับที่สองซึ่งรวมด้วยสารดูดซับที่สองที่มีขนาดเกรนใหญ่กว่าสารดูดซับที่หนึ่งและ ถูกห่อหุ้มโดยชิ้นส่วนดูดซับที่หนึ่งและวัสดุแกน The vacuum heat insulating material is combined with a core material which binds the vacuum space, the outer encapsulation material which encapsulates the core material, the first sorbent component combined with the first powder absorbent and the wrapping material. coat One where the first sorbent is encapsulated and placed in contact with the inner surface of the outer wrap, and the second sorbent, combined with a second sorbent with a larger grain size than the sorbent. First liner and Is encapsulated by one absorbent part and the core material.

Claims

1. Vacuum heat insulation material, which consists of: a core material which holds a vacuum space; External encapsulation material which encapsulates the core material; The first sorbent, which combines the first powdered absorbent and the first encapsulation material. The first sorbent coat, and placed in contact with the inner surface of the outer wrap material; And the second sorbent, combined with a second sorbent with a grain size larger than the first sorbent, and encapsulated by the first sorbent and core material.

2. Vacuum heat insulation material of claim No. 1 where adsorbent grain size The first sorbent was less than 0.1 mm on average, and the grain size of the second sorbent was 0.1 to 100 mm on average.
