The conventional corrosion resistance method of galvanized cable bridge stand:

　　1：熱浸鍍鋅 鋅在耐腐蝕上有著(zhù)出色的效果，鍍鋅的原理是在于鍍層破損或遭腐蝕生成Fe-Zn原電池時(shí)，鋅鍍層屬于陽(yáng)極性鍍層，鋅犧牲溶解，保護了鋼鐵。因此鋼鐵上的鍍鋅層不是單純的機械保護作用，而是通過(guò)電化學(xué)作用保護基體免遭腐蝕，即使鋅層不完整也會(huì )起到這個(gè)作用。這是一種犧牲陽(yáng)極來(lái)保護陰極金屬的辦法，壽命就在于它的腐蝕鋅鍍層的阻力以及腐蝕速度。通常熱浸鍍鋅的厚度在6um以上，鋅和鐵的接觸面結合成了一層鋅鐵合金，提高了鋅的附著(zhù)性，國外也專(zhuān)門(mén)為這一發(fā)現進(jìn)行了考究，在不同環(huán)境下的熱浸鍍鋅進(jìn)行了大氣露出實(shí)驗，研究表明這種方法適合針對防腐使用，所以大家可以盡量選擇鍍鋅橋架。鑒道橋架即是運用了這種處理方法。

　　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.涂防銹漆：又名“噴塑電纜橋架”，因為有些尺寸過(guò)大的鍍鋅橋架受到一定的設備限制，所以通常會(huì )運用操作簡(jiǎn)單方便的涂防銹漆。防銹漆由紅丹防銹漆、鐵紅酚醛防銹漆、鋅黃防銹漆等防銹漆，作用效果一般，防腐作用不強，為了保證工程的整個(gè)性以及使用效果，建議不使用這種方法。

　　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.電鍍鋅：電鍍鋅的操作過(guò)程中，比熱浸鍍鋅更簡(jiǎn)單，本錢(qián)相比之下也比較低，它撇棄了傳統方式的水電鍍，真空鍍，現在的方式更加的。在歷來(lái)工業(yè)上，電鍍等處理的工藝排出的廢液是非常污染環(huán)境和影響人體的，但是該工業(yè)已經(jīng)實(shí)現了的技術(shù)。電鍍鋅的厚度一般在6um左右，實(shí)際上來(lái)說(shuō)不太適合要求非常高的防腐蝕工程上。

　　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.
