氟磷铁防腐涂料是一种用于保护钢铁表面的新型防腐涂料,它不仅对介质有隔离屏蔽作用,还能使钢铁表面磷化致钝、残锈软化。之所以如此,是因为它含有一种由Na_3FeF_6、FePO_4、FeOF、Fe_2P_2O_7、NaH_2PO_4和Na_4P_2O_3等组成的无机氟磷铁颜料,当涂料接触金属表面时,颜料中的活性组份使钢铁基体上的水份进行水解,生成具有缓蚀作用的络合物。涂料的基本性能: 涂料样品由临海市某化工厂提供涂料的成膜物基料采用PVC树脂。涂料物理机械性能实测见下表:
Ferrofluric acid anti-corrosion coating is a new type of anti-corrosion coating used to protect the steel surface. It not only shields the medium but also blunts the surface of steel and softens the residual rust. The reason for this is that it contains an inorganic fluorophosphoric iron pigment composed of Na 3 FeF 6, FePO 4, FeOF, Fe 2 P 2 O 7, NaH 2 PO 4 and Na 4 P 2 O 3. When the coating touches the metal surface, the active component in the pigment causes the water Part of the hydrolysis, the formation of a complex with a corrosion inhibitor. Coatings of the basic performance: paint samples from a chemical plant in Linhai City, the coating material provided by the base material using PVC resin. Physical and mechanical properties of coatings measured in the table below:
