在许多场合下,实现机械化除锈是有困难的,而用手工除锈又要耗费大量的劳动工时,因此有必要研究一些在锈层上涂漆的方法. 在国外文献中曾介绍过一些反应性底漆,以及含有磷并能与锈起反应的络合物为基的特种材料. 苏联哥尔洛夫卡氮肥厂也提出过相类似的反应性底漆. 反应性底漆由铁锈转化剂及??-6型环氧树脂溶液所组成.铁锈转化剂为磷酸及黄血盐(亚铁氰化钾),两者之配比为8∶1. 把溶于甲苯的环氧树脂溶液(树脂为56个重量单位,甲苯为24个重量单位)涂到已涂转化剂并保持2～18小时后的表面上,环氧树脂藉多余的磷酸硬化.
In many cases, to achieve mechanized rust removal is difficult, and manual decontamination also takes a lot of man-hours, it is necessary to study some methods of painting the rust layer has been introduced in foreign literature some reactions Priming paints, as well as specialty materials based on complexes that contain phosphorus and can react with rust.Similarly reactive primers are also proposed in the Russian Federation of Fertilizers at the Gorlovka plant.Reactive primers consist of rust-converting agents And ?? - 6 type epoxy resin composition rust conversion agent is phosphoric acid and yellow blood salt (potassium ferrocyanide), the ratio between the two is 8: 1. Toluene dissolved in the epoxy resin solution ( Resin is 56 weight units and toluene is 24 weight units) is applied to the surface after the conversion agent has been applied for 2 to 18 hours, and the epoxy resin is hardened by the excess phosphoric acid.
