酸洗是电器制造业中箱体、台架加工中的重要环节之一。为了防止钢铁设备腐蚀,延长使用寿命,表面应做防护。在喷漆前,必须去除工件上的铁锈和氧化皮,这样才能使产品耐用。过去常用的除锈工艺是:把钢铁工件放入2530％的盐酸溶液中浸30～60分钟(因工件大小和结构繁简而异),再放入碱性溶液中中和,然后用加压缩空气的高压水冲洗干净,晾干,再用手工刷除工件表面微粒和浮锈后,立即喷涂铁红醇酸底漆。这种方法工序多,操作
Pickling is one of the most important parts in the manufacture of cabinets and benches in the electrical manufacturing industry. In order to prevent the corrosion of steel equipment, extend the service life, the surface should be protected. Before painting, rust and scale must be removed from the work piece to make the product durable. In the past commonly used rust removal process is: the steel workpiece immersed in 2530% hydrochloric acid solution for 30 to 60 minutes (due to the size of the workpiece and the structure of simple and concise), and then placed in alkaline solution and neutralized, The air of high pressure water rinse, dry, and then manually brush the surface of the workpiece particles and rust, spray iron red alkyd primer immediately. This method of operation and more operations
