1-简介 此程序的目的是确定中信用于消防系统地下管道防腐蚀保护的表面准备和喷漆应用过程中应遵循的最低要求。2- 一般条件 2.1 -对于新的表面，不论是否具有轧机氧化皮，表面处理均应通过干喷达到GRADE ISO 8501-1-Sa 2½（最小），然后用不含油，水和/或油的压缩空气进行详细清洁刷子/扫帚和/或吸尘器上的灰尘。 2.2-未组装的，无法通过手动和/或机械工具清洁的腐蚀表面应送至CSA现场以外的地方进行爆破。 2.3-在喷砂作业之前和通过机械和/或手动工具进行表面处理之前，必须对所有表面进行彻底的水清洁，以除去可溶性盐，灰尘，水泥和其他杂质。油，油脂，脂肪产品和其他油性污染物应通过溶剂清洗或工业可生物降解的洗涤剂彻底清除，然后用水冲洗。 2.4-在喷砂箱上按照GRADE ISO 8501-1-Sa 2½进行干喷，表面轮廓为40至85 µm，并在短时间内涂上第一道底漆或底漆。如果可能，必须立即涂上这道涂层。 2.5-组装和安装工作完成后，应尽可能采用GRADE ISO 8501-1-Sa 2½，表面粗糙度为40至85 µm的干喷方法，准备焊缝，锋利边缘和损坏的涂层。如果不可能的话，这些表面必须使用手动或机械工具进行准备，最低等级为GRADE ISO 8501-1 – St 3。 2.6-在进行表面处理之前，所有表面都必须以2.000至3.000 psi的水冲洗，并应遵循本文件规定的喷漆系统。 2.7 –如果对损坏的油漆进行修饰，则必须重复原始系统。只要不可能按照GRADE ISO 8501-1-Sa 2½进行喷砂处理，则在获得CSA批准后，应进行手动和/或机械清洁GRADE ISO 8501-1 – St 3（最小值）。 2.8 –为了通过喷砂处理来准备表面，中信公司应在CSA批准后，使用玄武岩和/或铜渣铸件作为GRADE ISO 8501-1-Sa 2½的磨料，表面轮廓为40至85 µm。
