一、前言气相防锈纸就是在中性原纸上涂以气相缓蚀剂的防锈包装材料。作为气相缓蚀剂的化学成份,亚硝酸盐占很重要的地位。如亚硝酸钠和亚硝酸二环己胺等含No_2~-的化合物至今仍在国内外广泛应用,特别是国内生产的防锈性能较好的防锈纸,其缓蚀剂配方中普遍以No_2~-化合物为主。No_2~-和仲胺在人体内,极容易合成亚硝胺,是一种强致癌物。
First, the preface Vapor phase rust paper is coated with a neutral corrosion inhibitor vapor corrosion packaging materials. As a chemical component of vapor corrosion inhibitor, nitrite plays a very important role. Such as sodium nitrite and nitrite dicyclohexylamine containing No_2 ~ - compounds are still widely used at home and abroad, especially the domestic production of rust-proof performance better rust-proof paper, the corrosion inhibitor formulations are generally No_2 ~ - compounds. No_2 ~ - and secondary amines in the human body, very easy to synthesize nitrosamines, is a strong carcinogen.
