摘要
钢管的表面处理是决定覆盖层质量的关键因素,对大多数覆盖层而言,喷(抛)丸除锈法是最理想的除锈方式。介绍了喷(抛)丸除锈用磨料的选择、种类及实验分析和使用情况。除锈用磨料分矿物质磨料和钢质磨料:①在钢质磨料中,钢丝磨料无论其本身的破碎率还是对叶轮、叶片的磨损都明显优于铸铁丸磨料。②在矿物质磨料中,2号燧石较石榴石破碎率低,而略高于1号燧石,但其硅的含量远远低于1号燧石,应优选2号燧石。
Surface cleaning is critically important for pipe coating, and shot (impeller) blasting is the most suitable derusting method for most kinds of coating materials. Introduced in the paper are the variety, selec- tion, experimental analysis and application of the abrasive materials for shot (impeller) blasting. Two kinds of derusting abrasives are available:(1)steel abrasives; Wire abrasives are superior both in fragmentation and in the wear on impellers and vanes; (2)mineral abrasives: Being lower than garnet but higher than 1# chert in fragmentation, 2# chert, with an much lower Si content than 1# chert, is preferred.
