补充资料:腐蚀控制
      指钢铁水管的腐蚀控制。金属表面在周围介质的作用下发生化学反应或电化学反应而遭受破坏称为腐蚀。腐蚀使管道内壁面变粗糙,水流的水头损失增加从而增加输水费用。腐蚀产物的积累减小管道的过水断面,从而降低管道的输水能力。严重时,管壁穿孔,管段破坏,造成停水检修。
  
  腐蚀的原因与表面材料的特性和周围介质的性质有关。金属表面繁殖的微生物有促进腐蚀的作用。影响管内壁面腐蚀速率的因素有水流的溶解氧、二氧化碳、氯离子、硫酸根离子、总溶解固体含量、pH值、温度、流速等。影响管外壁面腐蚀的因素有湿度、pH值和导电性能。
  
  控制水管腐蚀的主要方法有:①加保护性覆盖层或保护膜,以保护管道内壁;②采用阴极保护法以保护地下管道外壁(见给水管网养护);③水中加缓蚀剂,常用于循环冷却水系统,既保护管道内壁,又保护换热设备与水接触的表面;④采用耐腐蚀管材,如镀锌钢管、塑料管、石棉水泥管等。
  
  在敞开式循环冷却水系统中,由于冷却水通过冷却塔或池时溶解氧得到补充,同时水的溶解固体浓度又高,所以水的腐蚀性较高。腐蚀控制成为循环冷却水处理的主要内容之一(见循环冷却水系统)。主要的处理方法是投加缓蚀剂。其主要作用是抑制腐蚀中的电化学过程。缓蚀剂分为阳极缓蚀剂、阴极缓蚀剂和两极缓蚀剂。阳极缓蚀剂抑制腐蚀过程的阳极反应;阴极缓蚀剂抑制腐蚀过程的阴极反应;两极缓蚀剂同时抑制腐蚀过程的阳极反应和阴极反应。常用的缓蚀剂有铬酸盐、聚磷酸盐、膦酸盐、硅酸盐、钼酸盐、钨酸盐、亚硝酸盐、锌盐、苯并噻唑、有机胺、丹宁、木质素等。同时投加两种或两种以上缓蚀剂,可利用它们的协同作用以减少药剂用量。
