所謂気化性防錆剤を、紙に塗布又は含浸した気化性防錆
紙は良く知られており、産業用紙として金属類の保管、
輸送等に際して巾広く実用されている。"Prior art" Volatile rust-proof paper, which is paper coated with or impregnated with a so-called volatile rust preventive agent in which vaporized vapor exerts a rust-preventing effect on metals, has been well known and has been used as industrial paper. storage of metals,
It is widely used for transportation, etc.
一方、気化性防錆紙によって保護されるべき金属類の形

来の冷延鋼板に替わつて、各種亜鉛メッキを施した亜鉛
メッキ鋼板が用いられるようになってきている。On the other hand, the forms of metals that should be protected by vaporizable anti-rust paper are changing in various ways. For example, in the automobile industry, in order to improve rust resistance, conventional cold-rolled steel sheets are being used as steel sheets for body parts, etc. Instead, galvanized steel sheets coated with various types of galvanized steel have come to be used.
亜鉛メッキは、鋼板の発錆を防止するための処理である

条件が形成され、白錆が発生してしまうため、その改良
が強く望まれている。Galvanizing is a treatment to prevent steel sheets from rusting, but when placed under extremely high temperature conditions such as dew condensation, a new problem arises: white rust forms on the galvanized surface. Even if it is protected with anti-corrosion paper, it may be exposed to rain during storage or transportation, and ultra-high temperature conditions will be formed due to water intrusion, resulting in the formation of white rust, so it is strongly recommended to improve this. desired.
