不锈钢仓储与运输防锈:潮湿、隔离与吊装

不锈钢也会生锈:潮湿、氯离子、碳钢接触与划伤是主因。仓储要防潮、隔离、垫木与通风,运输要防雨防划伤。
不锈钢并非"永不生锈",仓储与运输不当会造成锈斑与划伤,常见原因与对策:
1) 潮湿与凝露:库房应干燥通风,避免露天堆放;雨季注意防潮,必要时除湿。 2) 氯离子污染:远离盐雾、含氯清洗剂与化工品;沿海地区尤其注意。 3) 碳钢接触:与碳钢直接接触会引入铁污染,导致锈点;应使用木垫、塑料垫或隔离纸,专用吊具。 4) 划伤:堆垛层间加垫纸/保护膜;吊装使用专用吊具与保护带,避免钢丝绳直接接触。 5) 包装:出口/海运需防潮包装(VCI 膜、干燥剂),木箱避免含水率过高。
检查与处理:发现锈点先判断是污染、点蚀还是缝隙腐蚀;可用蓝点试验检测游离铁;轻微锈斑可酸洗钝化处理,严重则降级。
仓储管理建议:按牌号/炉号分区、先进先出、避免混料;建立出入库记录与表面检查制度。
