The conventional corrosion resistance method of galvanized cable bridge stand:

　　1：热浸镀锌 锌在耐腐蚀上有着出色的效果，镀锌的原理是在于镀层破损或遭腐蚀生成Fe-Zn原电池时，锌镀层属于阳极性镀层，锌牺牲溶解，保护了钢铁。因此钢铁上的镀锌层不是单纯的机械保护作用，而是通过电化学作用保护基体免遭腐蚀，即使锌层不完整也会起到这个作用。这是一种牺牲阳极来保护阴极金属的办法，寿命就在于它的腐蚀锌镀层的阻力以及腐蚀速度。通常热浸镀锌的厚度在6um以上，锌和铁的接触面结合成了一层锌铁合金，提高了锌的附着性，国外也专门为这一发现进行了考究，在不同环境下的热浸镀锌进行了大气露出实验，研究表明这种方法适合针对防腐使用，所以大家可以尽量选择镀锌桥架。鉴道桥架即是运用了这种处理方法。

　　1: hot dip galvanized zinc has great effect on the corrosion resistance, that is, the principle of galvanized coating damage or corrosion generated by Fe - zinc galvanic, zinc coating belongs to the anode sex coating, zinc sacrifice to dissolve, to protect the steel. So the zinc coating on the steel was not a simple mechanical protection, but rather through electrochemical action to protect substrate from corrosion, even if incomplete zinc layer will play the role. This is a way of protecting the cathode metal from the anode, which is the resistance and corrosion of the zinc coating. Usually the thickness of the hot dip galvanized above 6 um, zinc and iron in the contact area combine into a layer of zinc iron alloy, improves the adhesion of zinc, abroad specifically for the fastidious, the discovery in a different environment atmosphere above experiments, the hot dip galvanizing of research shows that this method is most suitable for used for corrosion protection, so we can try to choose galvanized bridge. The bridge is used for this treatment.

　　2.涂防锈漆：又名“喷塑电缆桥架”，因为有些尺寸过大的镀锌桥架受到一定的设备限制，所以通常会运用操作简单方便的涂防锈漆。防锈漆由红丹防锈漆、铁红酚醛防锈漆、锌黄防锈漆等防锈漆，作用效果一般，防腐作用不强，为了保证工程的整个性以及使用效果，建议不使用这种方法。

　　2. Coating antirust paint, also known as "plastic cable tray, because some size is too large galvanized bridge is limited by certain equipment, so often use the most simple and convenient operation with anticorrosive paint. Antirust paint the red lead, iron oxide red phenolic anti-rust paint, zinc yellow antirust paints such as antirust paint, effect, corrosion protection is not strong, in order to guarantee the whole engineering safety and using effect, suggest don't use this method.

　　3.电镀锌：电镀锌的操作过程中，比热浸镀锌更简单，本钱相比之下也比较低，它撇弃了传统方式的水电镀，真空镀，现在的方式更加的。在历来工业上，电镀等处理的工艺排出的废液是非常污染环境和影响人体的，但是该工业已经实现了的技术。电镀锌的厚度一般在6um左右，实际上来说不太适合要求非常高的防腐蚀工程上。

　　3. Electricity galvanized, electric galvanized the operation of the process, the specific heat galvanizing is more simple, the capital, by contrast is low, it abandoned the traditional way of water plating, vacuum plating, now way more environmentally friendly. In the traditional industry, the waste liquor from the process of electroplating and other processing is very polluting and affecting the human body, but the industry has already achieved the environmental protection technology. The thickness of electrogalvanizing is generally around 6um, which is not very suitable for very high corrosion prevention engineering.
