Cable trays are commonly used materials and facilities for electrical installation in engineering, which are superior to pipelines due to the convenience of laying multiple cables. Especially in the case of system trunk lines and centralized wiring, their superiority is reflected. There are various forms of cable trays, such as slot type tray type ladder type. There are also many types of materials and processes for cable trays, 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 protection requirements, there are fire resistant and fire-resistant cable trays. The performance characteristics of each material and process are different, and cable trays are mainly used to support cable protection cables and manage cables, bringing great convenience to our cable route management.

镀锌桥架：

Galvanized cable tray:

镀锌桥架又名电镀锌桥架；一般人理解为镀锌桥架以为是热镀锌桥架，其实是不对的，跟镀锌管一样，桥架的镀锌也分两种，即冷镀锌（电镀锌和热镀锌（热浸镀锌；

Galvanized cable tray, also known as galvanized cable tray; It is generally understood that galvanized cable trays are considered hot-dip galvanized, but it is actually incorrect. Like galvanized pipes, there are two types of galvanizing for cable trays: cold galvanizing (electro galvanizing) and hot galvanizing (hot dip galvanizing);

钢铁在空气水或土壤中很容易生锈，甚完全损坏。每年因腐蚀造成的钢铁损失约占整个钢铁产量的1/10，另一方面，为使钢铁制品与零件表面具有某种特殊功能，同时赋予其表面装饰性的外观，所以，一般采用电镀锌的方式对其处理。

Steel is prone to rust 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 to treat them.

原理：

Principle:

由于锌在干燥空气中不易变化，而在潮湿的空气中，表面能生成一种很致密的碱式碳酸锌薄膜，这种薄膜能有效保护内部不再受到腐蚀。并且当某种原因，使镀层发生破坏而露出不太大的钢基时，锌与钢基体形成微电池，使钢基体成为阴极而受到保护。

Due to the fact that zinc is not easily changed in dry air, and in humid air, a dense alkaline 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 micro battery with the steel substrate, making the steel substrate a cathode and protected.

性能特点：

Performance characteristics:

锌镀层较厚，结晶细致均匀且无孔隙，抗腐蚀性良好；

The zinc coating is thick, with fine and uniform crystallization without pores, and has good corrosion resistance;

电镀所得锌层较纯，在酸碱等雾气中腐蚀较慢，能有效保护钢基体；

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

锌镀层经铬酸钝化后形成白色彩色军绿色等，美观大方，具有一定的装饰性；

The zinc coating is passivated with chromic acid to form white, colorful military green, etc., which is beautiful and elegant, and has a certain degree of decoration;

由于锌镀层具有良好的延展性，因此可进行冷冲轧制折弯等各种成型而不损坏镀层。

Due to the excellent ductility of zinc coating, it can be formed through various processes such as cold stamping, rolling, and bending without damaging the coating.

应用范围：

Application scope:

随着科学技术生产的发展，电镀工业所涉及的领域越来越广泛。目前，电镀锌的应用已遍及国民经济的各个生产和研究部门。例如，机器制造电子精密仪器化工轻工交通运输兵器航天原子能等等，在国民经济中有重大意义。

With the development of scientific and technological production, the electroplating industry involves an increasingly wide range of fields. At present, the application of electrogalvanizing has spread to various production and research departments of the national economy. For example, machine manufacturing, electronic precision instruments, chemical industry, light industry, transportation, weapons, aerospace, atomic energy, etc., have significant significance in the national economy.
