電纜橋架表面處理可以采取哪些方法？
電纜橋架是一種能保護(hù)電纜不受外界因素?fù)p壞的建筑材料，在現(xiàn)在的生活中電纜橋架已經(jīng)到處都可以見到，比如地下停車場(chǎng)、、酒店等地方，但是還是有很多朋友對(duì)電纜橋架不是很了解，下面電纜橋架廠家就來給大家介紹一下電纜橋架的表面處理的方法有哪些。
Cable tray is a kind of building material that can protect cables from external factors. Cable tray can be seen everywhere in today's life, such as underground parking lots, supermarkets, hotels and other places, but many friends still don't know much about cable tray, The following cable tray manufacturers will introduce to you the surface treatment methods of cable tray.
電纜橋架的表面處理可以是：熱浸鍍鋅，冷鍍鋅，靜電粉末噴涂等。在熱鍍鋅電纜橋架表面覆蓋一層致密而厚的保護(hù)層。它完全避免鋼與某些腐蝕性物質(zhì)接觸，保護(hù)鋼材免受破壞。
The surface treatment of cable tray can be: hot dip galvanizing, cold galvanizing, electrostatic powder spraying, etc. The surface of hot-dip galvanized cable tray shall be covered with a dense and thick protective layer. It completely prevents the steel from contacting with some corrosive substances and protects the steel from damage.
新表面還產(chǎn)生鋅鹽，難以溶于水并且更具康復(fù)性。因此，海洋鹽霧氣氛中的一些項(xiàng)目也可以得到很好的保護(hù)。同時(shí)，加熱工程中產(chǎn)生的鐵鋅混合物具有較高的耐磨性。有四種常用的鍍鋅方法：
The new surface also produces zinc salts, which are difficult to dissolve in water and more restorative. Therefore, some projects in marine salt fog atmosphere can also be well protected. At the same time, the iron zinc mixture produced in heating engineering has high wear resistance. There are four common galvanizing methods:
1、熱浸鍍鋅：
1. Hot dip galvanizing:
熱浸鍍鋅用作犧牲陽(yáng)極以保護(hù)陰極金屬。耐腐蝕性取決于鍍鋅層的厚度和腐蝕速率。熱浸鍍鋅中鋅層的厚度一般在65um（455g/m2）以上。鋅和鐵的組合表面形成一層鋅合金，鋅層增強(qiáng)附著力。在熱浸鍍鋅中，很容易產(chǎn)生變形等。在電纜橋架和鍍鋅工藝中需要考慮它。
Hot dip galvanizing is used as sacrificial anode to protect cathode metal. Corrosion resistance depends on the thickness of zinc coating and corrosion rate. The thickness of zinc layer in hot-dip galvanizing is generally more than 65um (455G / m2). A layer of zinc alloy is formed on the combined surface of zinc and iron, and the zinc layer enhances the adhesion. In hot-dip galvanizing, deformation is easy to occur. It needs to be considered in cable tray and galvanizing process.
2、冷鍍鋅：
2. Cold galvanizing:
與熱浸鍍鋅相比，工藝簡(jiǎn)單，成本低。電纜橋架的結(jié)構(gòu)沒有特殊要求。鈍化處理后，鍍鋅鍍鋅的保護(hù)性能可大大提高。鍍鋅層通常約為12/zm。因此，它不適用于高耐腐蝕性的情況。
Compared with hot-dip galvanizing, the process is simple and the cost is low. There are no special requirements for the structure of cable tray. After passivation treatment, the protective performance of zinc plating can be greatly improved. The zinc coating is usually about 12 / ZM. Therefore, it is not suitable for high corrosion resistance.
3、粉末噴霧：
3. Powder spray:
噴涂材料一般為聚氯乙烯粉末，聚酯粉末或防腐蝕粉末。涂層的厚度約為100/1rn。靜電噴涂具有外觀美觀，抗化學(xué)腐蝕性能好的特點(diǎn)。
Spraying materials are generally PVC powder, polyester powder or anti-corrosion powder. The thickness of the coating is about 100 / 1RN. Electrostatic spraying has the characteristics of beautiful appearance and good chemical corrosion resistance.
