应用拉曼光谱研究了含有防锈颜料涂装特性的钢样,在此基础上探讨了三聚磷酸铝防锈颜料对A3 钢的保护机理.三聚磷酸铝溶解后能到达钢样表面,其离子可与铁离子化合形成三聚磷酸铁.三聚磷铁能缓慢地通过化学键牢固地附着在钢样表面,最终在钢表面形成一层隔绝腐蚀介质和钢样的紧蜜保护膜阻止了腐蚀的继续发生从而达到保护的目的.
應用拉曼光譜研究瞭含有防鏽顏料塗裝特性的鋼樣,在此基礎上探討瞭三聚燐痠鋁防鏽顏料對A3 鋼的保護機理.三聚燐痠鋁溶解後能到達鋼樣錶麵,其離子可與鐵離子化閤形成三聚燐痠鐵.三聚燐鐵能緩慢地通過化學鍵牢固地附著在鋼樣錶麵,最終在鋼錶麵形成一層隔絕腐蝕介質和鋼樣的緊蜜保護膜阻止瞭腐蝕的繼續髮生從而達到保護的目的.

The painted steel sample whose coating contained anticorrosive pigment has been investigated by Raman spectroscopy.The protective mechanism of aluminum triphosphate pigment for A3 steel is proposed as follows: Aluminum triphosphate can be dissolved and arrive at the surface of the steel.The dissolved triphosphate ions can complex with ferric ions.And the new products,namely ferric triphosphate,can strongly adhere at the surface of the steel by chemical bonds slowly.At last,a compact protective film,which effectively separates the steel substrate from the aggressive media,is formed at the steel surface.
