...Metals can have a thin layer of other metals applied to their surfaces by plating, but metal foils are also used on nonmetallic materials such as wood. When we hear "metal foil," we think of silver paper or gold leaf, but modern silver paper is often aluminum foil (aluminum foil) and is not actually silver. The thinnest aluminum foil is 5 μm thick, and is manufactured industrially using the same rolling machines as plate rolling machines (for example, a reversible four-high rolling machine with a work roll diameter of about 250 mm) to apply tension from both the front and back, with careful attention to lubrication, at a relatively high rolling speed (about several hundred meters/min). ... *Some of the terminology that mentions "aluminum foil" is listed below.

…金属はめっきなどによってその表面に他の金属の薄い層をつけることができるが,木材などの非金属にも金属箔を用いることがある。金属箔と聞くと,銀紙,金箔などを連想するが,現代の銀紙は多くの場合アルミニウム箔(アルミフォイル)であり,ほんとうの銀ではない。アルミニウム箔の最も薄いものは5μmの厚さであり,工業的には板圧延機と同じ圧延機(たとえばワークロール径250mm程度の可逆式4段圧延機)を用い,前後から張力を付加し,潤滑に注意しつつ比較的高い圧延速度(数百m/min程度)で製造される。… ※「アルミフォイル」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
