12、量锌腐蚀物如锌盐，这一点是非常重要的。表面应清洁，干燥，经过打磨且无锌盐污染物。4.2 Usually, sweep blasting on galvanizing steel is a preferable method to coat.

Non-ferrous abrasive shall be used, e.g. copper slag, silica sand, aluminum oxide or garnet and etc fine grade (80 mesh) nonmetallic abrasive shall be recommended. 通常，对镀锌钢表面进行扫砂处理是最为理想的方法。在对镀锌或喷锌表面进行冲砂之前，须对表面存在的白色锌盐进行水冲洗，然后根据SSPC SP1的要求进行溶剂清理，以去除可见油脂等污染物。按照ISO
15、 8501-1 Sa 1或SSPC SP 7的方法和标准对镀锌表面作扫砂处理，并获得20-30微米的表面粗糙度。进行扫砂处理时，所使用的压缩空气不应太高(4-5kg/cm2)。扫砂时喷枪距离表面保持约1米距离并快速移动。扫砂时应使用非铁质的细磨料(80目)，如铜矿渣，石英砂，棕刚玉或石榴石等可推荐使用。5.
