Description

一种链条防腐处理方法 技术领域
本发明涉及船舶、海洋、机械工程和采矿工程的领域，尤其涉及各种链环的表面防腐处理方法。
背景技术
随着船舶、海工和机械行业的发展，锚链、系泊链、刮板链和其他工程用钢制链条应用也越来越广泛，这些产品常常需要在海边、海水、含硫化氢等腐蚀条件下服役，对防腐性能提出了较高的要求。传统的防腐措施是浸涂沥青等涂料，具有施工方便的特点，但是容易产生流挂等缺陷，影响使用；而使用烤漆工艺复杂，对于大直径以及长链条操作难度大，施工困难；此外，在船舶和海工领域，常常使用热喷铝或热镀锌的方法提高链条防腐性能，该工艺防腐效果好，但是涂层消耗快，难以保证长达5～25年的寿命要求。因此，提供一种易于施工，能够保证长期有效的链条表面防腐处理方法很有必要。
发明内容
本发明的目是解决上述技术问题，提供一种低磁锚链的表面检查方法。
为了实现上述技术目的，达到上述的技术要求，本发明所采用的技术方案是：
一种链条防腐处理方法，其特征在于：包括以下步骤：
步骤一、将多根链条平铺在干净的地面上，使用工具将链环与链环接触的部位松开以便于施加涂层；
步骤二、由于抛丸时链环与链环接触部位钢粒无法达到，施加涂层前应使用砂轮或砂纸对松开后的接触部位进行表面清理；
步骤三、对链条的正面刷涂或喷涂底漆，间隔不少于1天时间后，将链条翻转180°，翻转后使用工具再次将链环与链环接触部位松开，再刷涂或喷涂链条的底面；所述底漆采用添加有锌粉的防腐底漆，防腐底漆中锌含量为50～80％；
步骤四、待底漆干后按步骤三方法刷涂或喷涂中间层漆；
步骤五、待中间层漆干后按步骤三方法刷涂或喷涂面漆；
步骤六、打包时采用起吊机，每隔若干个环数用吊索穿过链环；应使用软质材料的吊索，以免破坏涂层。
优选的，所述步骤一中多根链条平铺时，链条与链条之间的间隔不小于20cm。
优选的，所述步骤三中链环与链环接触部位松开时，使用的工具应包覆软质材料，以 免破坏涂层。
与传统结构相比,本发明的有益效果：易于施工，不会产生流挂缺陷，防腐性能好，能够保证其在破损情况下仍能保持较好的防腐效果，同时满足链条长期在腐蚀环境下服役的要求，尤其是适用于大规格长链条。
