汉江跨越管桥钢索的防腐

Corrosion Control for the Cables of the Pipe Bridge over Hanjiang River

  • 摘要: 管桥的钢索承受着管桥的全部重量, 它的防腐问题直接影响着管桥的寿命。用传统的地蜡防腐方法, 存在着使用寿命短、年平均施工费用高、大修周期短等问题。因此, 需要一种施工简单、粘结牢固、寿命长的防腐材料。在进行了大量的调研和试验之后, 认为改性橡胶自粘防腐胶带能够适应钢索防腐施工中高空作业多、施工条件差的特点。其优点是: 具有非常好的电绝缘性能、耐化学腐蚀及耐低温性能; 操作简便; 不需加热和其它处理。缠绕后, 在常温下自然硫化粘合, 形成严密的保护层, 是一种较为理想的管桥钢索防腐材料。

     

    Abstract: Pipe bridge is fully supported by the steel cables, the corrosion control of which determines the service life of pipe bridge. The conventional corrosion protection method, realized by ader wax, has such disadvantages as limited service life, high annual cost, short overhaul interval, etc. Therefore, a new anticorrosion material is needed of ease of application, high cohesive strength and long service life. It is proved on the basis of investigations and testings that cohesive tape of modified rubber is suitable for coating on steel cables under adverse conditions. Having such advantages as exerlent electric insulation property, chemical corrosion resistance and lower-temperature resistance, case of application, unnecessity for heating and treatment, the modified rubber becomes cohesive at ambient temperature and forms a tight film while preventing the cables from being corroded.
