Surface Preparation for the galvanized mesh镀锌构件表面处理4.1 Removal of excessive zinc

11、 corrosion product e.g. zinc slats on the galvanizing or zinc sprayed layers prior to the application of specified primer is very important to ensure satisfactory adhesion and optimal performance. Surface should be clean, dry, abraded and free from zinc salts contamination.为了确保满意的附着性和最佳性能，在涂覆规定底漆之前，

12、先清除镀锌或喷锌表面上的过量锌腐蚀物如锌盐，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. Prior to blasting the galvanizing or zinc sprayed layers, water rinse to remove all white zinc salts on the surface, and solvent clean according to SSPC SP 1 to remov

13、e any visible oil, grease, etc contaminants. Sweep blasting clean the zinc surface in order to obtain the proper surface profile in 20-30 microns in conformance with ISO 8501-1 Sa 1 or SSPC SP 7.

14、 move it quickly in the operation of sweep blasting. 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

15、见油脂等污染物。按照ISO 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.
