设备或钢结表面除锈的质量等级要求

本帖最后由 晓昀 于 2019-8-16 11:00 编辑

      最近,我们制造厂因为一项目的设备和钢结构的表面除锈处理出问题,导致外观喷涂效果很差,影响设备美观和设备按时出厂,最后返工,设计和制造车间出现互相扯皮。今天做了一个文件,分享给各位社友。


1、表面处理方法
设备及管道表面处理的方法常用的方法有工具除锈、喷射或抛射除锈。
(1)工具除锈
1)工具除锈可分为手动和动力工具除锈两种方法。手动工具包括钢丝刷、粗砂纸、钟刀、刮刀或类似手工T具。动力工具包括旋转钢丝刷、电动砂轮或除锈机等。
2)工具除锈应注意下列问题:动力工具不能达到的地方,应用手动工具做补充清理。用工具除锈时不应造成钢材表面损伤,表面粗糙度应符合规定,不得将钢材表面磨得过光或过于粗糙。
(2)喷射除锈法
1)喷射除锈指用压缩空气将磨料高喷射到金属表面,依靠磨料的冲击和研磨作用,将金属表面的铁锈和其他污物清除。
2)常以石英砂作为喷射除锈用磨料,称为喷砂除锈。
3)喷射除锈广泛用于施工现场设备及管道涂覆前的表面处理。
(3)抛射除锈法
1)抛射除锈法是利用高速旋转的叶参,将进人叶轮腔体内的磨料在离心力作用下由开口处以45°~50°的角度定向抛出,射向被除锈的金属表面。
2)常以铸钢丸作为抛射除锈用磨料,称为抛丸除锈。
3)抛射除锈主要用于涂覆车间工件的金属表面处理。
2.表面处理等级
钢材表面处理等级用代表相应处理方法类型的字母“Sa”、"St"表示。
(1)手工或动力工具除锈质量等级
手工或动力工具除锈金属表面处理等级分为St2级、St3级两级。
1)St2级:初底的手工和动力工具除锈。钢材表面无可见的油脂和污垢且没有附牢不牢的氧化皮、铁锈和油表涂层等附着物。
2)St3级:非常彻底的手工和动力工具除锈。钢材表面无可见的油脂和污垢且没有附着不牢的氧化皮、铁锈和油漆涂层等附着物,除锈应比S2级更为彻底,基体显露部分的表面应具有金属光泽。
(2)喷 射或抛射除锈质量等级
喷射或抛射除锈金属表面处理质量等级分为Sa1级、Sa2级、Sa2.5级、Sa3级四级。
1)Sa1级:轻度的喷射或抛射除。钢材表面无可见的油脂和污垢,且没有附着不牢的氧化皮,铁锈和油漆涂层等附着物。
2)Sa2级:彻底的射或抛射除锈。钢材表面无可见的油脂和污垢,且氧化皮、铁锈和油涂层等附着物已基本清除,其戏留物应是牢固附着的
3)Sa2.5级:非常彻底的喷射或射除锈。钢材表面无可见的油脂、污垢、氧化皮铁锈和油漆涂层等附着物,任何残留的痕迹应仪是点状或条纹状的轻微色斑。
4)Sa3级:使金属表观洁净的喷射或抛射除锈。钢材表面无可见的油,污后,氧化皮,铁诱和油康涂层等附着物,该表面应显示均匀的金属色洋
3.表面处理要求
(1)清程度要求
1)达到处理等级要求
当设计材基体表面处理无要求时,其基体表面处理的质量要求应符合下表中的规定。

图纸技术要求中到底标St级还是Sa级要弄清楚。
St级是手动工具或者电动工具除锈,St3级的质量等级最高;Sa级是喷射或者抛射除锈,Sa3级的质量等级最好,除锈后出现金属纹理。
