大家知道，工程中電纜橋架是電氣安裝常用的材質(zhì)設(shè)施，以敷設(shè)線纜多、施工方便而優(yōu)于管道，尤其在系統(tǒng)干線，集中布線的場合更加體現(xiàn)其優(yōu)越性。橋架的形式有槽式、托盤式、梯架式等多種。橋架也有很多種材質(zhì)和不同類型的工藝，比如材質(zhì)分為：不銹鋼、鋁合金、玻璃鋼等材質(zhì)；工藝分為：熱鍍鋅、靜電噴塑、鍍鋅等工藝；另外按消防要求還有防火與耐火的橋架。每種材質(zhì)和工藝的性能特點(diǎn)都是不同的，電纜橋架主要用途是用來支撐電纜、保護(hù)電纜以及管理電纜的，給我們的電纜線路管理帶來了很大的方便。一、鍍鋅橋架與熱鍍鋅橋架（熱浸鋅橋架）區(qū)別?

　　As we all know, cable trays are commonly used materials and facilities for electrical installation in engineering. They are superior to pipelines in terms of laying more cables and convenient construction, especially in the case of system trunk lines and centralized wiring, which further demonstrates their superiority. There are various forms of cable trays, such as trough type, tray type, ladder type, etc. There are also many types of materials and techniques for bridge frames, such as stainless steel, aluminum alloy, fiberglass, and other materials; The process is divided into: hot-dip galvanizing, electrostatic spraying, galvanizing and other processes; In addition, according to fire safety requirements, there are fire-resistant and fire-resistant cable trays. The performance characteristics of each material and process are different. Cable trays are mainly used to support cables, protect cables, and manage cables, which brings great convenience to our cable line management. 1、 What is the difference between galvanized cable tray and hot-dip galvanized cable tray (hot-dip galvanized cable tray)?

　　鍍鋅橋架：鍍鋅橋架又名電鍍鋅橋架；一般人理解為鍍鋅橋架以為是熱鍍鋅橋架，其實(shí)是不對的，跟鍍鋅管一樣，橋架的鍍鋅也分兩種，即冷鍍鋅（電鍍鋅）和熱鍍鋅（熱浸鍍鋅）；?

　　Galvanized bridge: Galvanized bridge, also known as electroplated galvanized bridge; The general understanding of galvanized cable trays as hot-dip galvanized cable trays is incorrect. Like galvanized pipes, the galvanizing of cable trays can be divided into two types: cold galvanizing (electroplating) and hot-dip galvanizing (hot-dip galvanizing);?

　　鋼鐵在空氣、水或土壤中很容易生銹，甚完全損壞。每年因腐蝕造成的鋼鐵損失約占整個(gè)鋼鐵產(chǎn)量的1/10，另一方面，為使鋼鐵制品與零件表面具有某種特殊功能，同時(shí)賦予其表面裝飾性的外觀，所以，一般采用電鍍鋅的方式對其處理。1、原理：

　　Steel is prone to rusting and even complete damage in air, water, or soil. The annual steel loss caused by corrosion accounts for about 1/10 of the entire steel production. On the other hand, in order to give steel products and parts a special function on the surface and give them a decorative appearance, electroplating is generally used for treatment. 1. Principle:

　　由于鋅在干燥空氣中不易變化，而在潮濕的空氣中，表面能生成一種很致密的堿式碳酸鋅薄膜，這種薄膜能有效保護(hù)內(nèi)部不再受到腐蝕。并且當(dāng)某種原因，使鍍層發(fā)生破壞而露出不太大的鋼基時(shí)，鋅與鋼基體形成微電池，使鋼基體成為陰極而受到保護(hù)。2、性能特點(diǎn)：

　　Due to the fact that zinc is not easily changed in dry air, while in humid air, a very dense basic zinc carbonate film can be formed on the surface, which can effectively protect the interior from corrosion. And when for some reason, the coating is damaged and a relatively small steel substrate is exposed, zinc forms a microbattery with the steel substrate, making the steel substrate a cathode and protected. 2. Performance characteristics:

　　1）鋅鍍層較厚，結(jié)晶細(xì)致、均勻且無孔隙，抗腐蝕性良好；

　　1) The zinc coating is thick, with fine and uniform crystallization and no pores, and has good corrosion resistance;

　　2）電鍍所得鋅層較純，在酸、堿等霧氣中腐蝕較慢，能有效保護(hù)鋼基體；

　　2) The zinc layer obtained by electroplating is relatively pure and corrodes slowly in acid, alkali and other mist, which can effectively protect the steel substrate;

　　3）鋅鍍層經(jīng)鉻酸鈍化后形成白色、彩色、軍綠色等，美觀大方，具有一定的裝飾性；

　　3) After chromic acid passivation, the zinc coating forms white, colored, military green, etc., which are aesthetically pleasing and have a certain degree of decorative value;

　　4）由于鋅鍍層具有良好的延展性，因此可進(jìn)行冷沖、軋制、折彎等各種成型而不損壞鍍層。3、應(yīng)用范圍：

　　4) Due to its excellent ductility, zinc coating can be formed through various processes such as cold stamping, rolling, bending, etc. without damaging the coating. 3. Application scope:

　　隨著科學(xué)技術(shù)生產(chǎn)的發(fā)展，電鍍工業(yè)所涉及的領(lǐng)域越來越廣泛。目前，電鍍鋅的應(yīng)用已遍及國民經(jīng)濟(jì)的各個(gè)生產(chǎn)和研究部門。例如，機(jī)器制造、電子、精密儀器、化工、輕工、交通運(yùn)輸、兵器、航天、原子能等等，在國民經(jīng)濟(jì)中有重大意義。

　　With the development of scientific and technological production, the fields involved in the electroplating industry are becoming increasingly extensive. At present, the application of galvanizing has spread to various production and research sectors of the national economy. For example, machine manufacturing, electronics, precision instruments, chemical industry, light industry, transportation, weapons, aerospace, atomic energy, and so on, have significant importance in the national economy.

　　熱鍍鋅橋架（熱浸鋅橋架）?1、熱浸鋅說明：

　　Hot dip galvanized bridge (hot-dip galvanized bridge)? 1. Hot dip galvanizing instructions:

　　在各種保護(hù)鋼基體的涂鍍方法中，熱浸鋅是非常優(yōu)良的一種。它是在鋅呈液體的狀態(tài)下，經(jīng)過了相當(dāng)復(fù)雜的物理、化學(xué)作用之后，在鋼鐵上不僅鍍上較厚的純鋅層，而且還生成一種鋅一鐵合金層。這種鍍法，不僅具備了電鍍鋅的耐腐蝕特點(diǎn)，而且由于具有鋅鐵合金層。還具有電鍍鋅所無法相比擬的強(qiáng)耐蝕性。因此這種鍍法特別適用于各種強(qiáng)酸、堿霧氣等強(qiáng)腐蝕環(huán)境中。

　　Among various coating methods for protecting steel substrates, hot-dip galvanizing is an excellent one. It is a process in which zinc is in a liquid state and undergoes complex physical and chemical reactions, resulting in the deposition of a thick layer of pure zinc on steel and the formation of a zinc iron alloy layer. This plating method not only has the corrosion resistance characteristics of electroplated zinc, but also has a zinc iron alloy layer. It also has strong corrosion resistance that cannot be compared to electroplated zinc. Therefore, this plating method is particularly suitable for various strong acid, alkali mist and other highly corrosive environments.

　　2、原理：熱浸鋅層是鋅在高溫液態(tài)下，分三個(gè)步驟形成的：

　　2. Principle: The hot-dip zinc layer is formed by zinc in a high-temperature liquid state in three steps:

　　1）鐵基表面被鋅液溶解形成鋅—鐵合金相層；

　　1) The iron-based surface is dissolved by zinc solution to form a zinc iron alloy phase layer;

　　2）合金層中的鋅離子進(jìn)一步向基體擴(kuò)散形成鋅鐵互溶層；

　　2) The zinc ions in the alloy layer further diffuse into the matrix to form a zinc iron miscible layer;

　　3）合金層表面包絡(luò)著鋅層。3、性能特點(diǎn)：

　　3) The surface of the alloy layer is enveloped by a zinc layer. 3. Performance characteristics:

　?。?） 具有較厚的致密的純鋅層覆蓋在鋼鐵表面上，它可以避免鋼鐵基體與任何的腐蝕溶液的接觸，保護(hù)鋼基體免受腐蝕。在一般大氣中，鋅層表面形成一層很薄而密實(shí)的氧化鋅層表面，它很難溶于水，故對鋼基體起著一定保護(hù)作用。如果氧化鋅與大氣中其它成分生成不溶性鋅鹽后，則防蝕作用更理想。

　　(1) A thick and dense pure zinc layer covers the surface of the steel, which can prevent the steel substrate from coming into contact with any corrosive solution and protect the steel substrate from corrosion. In the general atmosphere, a thin and dense layer of zinc oxide is formed on the surface of the zinc layer, which is difficult to dissolve in water and therefore plays a certain protective role on the steel substrate. If zinc oxide forms insoluble zinc salts with other components in the atmosphere, the anti-corrosion effect is more ideal.

　?。?） 有鐵—鋅合金層，結(jié)合致密，在海洋性鹽霧大氣及工業(yè)性大氣中表現(xiàn)特有抗腐蝕性；

　　(2) There is an iron zinc alloy layer, which is dense and exhibits unique corrosion resistance in marine salt spray and industrial atmospheres;

　?。?） 由于結(jié)合牢固，鋅—鐵互溶，具有很強(qiáng)的耐磨性；

　　(3) Due to its strong bonding and zinc iron compatibility, it has strong wear resistance;

　?。?） 由于鋅具有良好的延展性，其合金層與鋼基附著牢固，因此熱鍍件可進(jìn)行冷沖、軋制、拉絲、彎曲等各種成型而不損壞鍍層；

　　(4) Due to the excellent ductility of zinc, its alloy layer adheres firmly to the steel substrate, allowing hot-dip plated parts to be formed through various processes such as cold stamping, rolling, drawing, and bending without damaging the coating;

　　（5） 鋼結(jié)構(gòu)件熱鍍鋅后，相當(dāng)于一次退火處理，能有效改善鋼基體的機(jī)械性能，鋼件成型焊接時(shí)的應(yīng)力，有利于對鋼結(jié)構(gòu)件進(jìn)行車削加工。

　　(5) After hot-dip galvanizing of steel structural components, it is equivalent to one annealing treatment, which can effectively improve the mechanical properties of the steel substrate, eliminate the stress during the forming and welding of steel components, and facilitate the turning processing of steel structural components.

　　（6） 熱鍍鋅后的配件表面光亮美觀。

　　(6) The surface of the accessories after hot-dip galvanizing is bright and beautiful.

　?。?） 純鋅層是熱鍍鋅中富有塑性的一層鍍鋅層，其性質(zhì)基本接近于純鋅，具有延展性，所以它富于撓性。4、應(yīng)用范圍：

　　(7) The pure zinc layer is the most plastic layer of hot-dip galvanizing, with properties similar to pure zinc and ductility, making it flexible. 4. Application scope:

　　熱鍍鋅的應(yīng)用隨著工農(nóng)業(yè)的發(fā)展也相應(yīng)擴(kuò)大。因此，熱鍍鋅制品在工業(yè)（如化工設(shè)備、石油加工、海洋勘探、金屬結(jié)構(gòu)、電力輸送、造船等），農(nóng)業(yè)（如：噴灌、暖房）、建筑（如：水及煤氣輸送、電線套管、腳手架、房屋等）、橋梁、運(yùn)輸?shù)确矫?，近幾年已大量地被采用。由于熱鍍鋅制品具有外表美觀、耐腐蝕性能好等特點(diǎn)，其應(yīng)用范圍越來越廣泛。

　　The application of hot-dip galvanizing has also expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, etc.), agriculture (such as sprinkler irrigation, greenhouses), construction (such as water and gas transportation, wire conduit, scaffolding, houses, etc.), bridges, transportation, and other fields in recent years. Due to its beautiful appearance and good corrosion resistance, hot-dip galvanized products are becoming increasingly widely used.
