在生产中经常遇到大型设备的金属零、部件表面受到周围介质的电化学作用和各种有害气体及物质的腐蚀发生严重锈蚀,影响使用。为了修复设备投入生产,往往采用砂布擦,砂轮磨,钢丝轮打磨、锉刀锉、刮刀刮等方法除锈,效果不好。如采用下面介绍的化学涂料除锈剂,既省力,效果又好。 In the production of metal often encountered large equipment, parts of the surface by the surrounding medium of electrochemical and various harmful gases and substances corrosion serious corrosion affect the use. In order to repair the equipment put into production, often use emery cloth, grinding wheel, wire wheel grinding, file rasp, scraper shaving and other methods of rust, the effect is not good. Such as the use of chemical coating descaling agent described below, both labor-saving, effective and good.
