　　浸锌是一种保护性钢结构涂镀工艺，是桥架生产常见的防腐方式。热浸锌工艺的电缆桥架可以适合各种酸碱盐雾等腐蚀环境、热浸锌电缆桥架用锌占全球锌产量的40%，作为产锌大国，也是我国开发的高附加值短线产品。

　　Zinc immersion is a protective coating process for steel structures and a common anti-corrosion method in bridge production. The cable tray produced by hot-dip galvanizing process can be suitable for various corrosive environments such as acid, alkali, salt spray, etc. Zinc used in hot-dip galvanizing cable trays accounts for 40% of global zinc production. As a major zinc producing country, it is also a high value-added short-term product that China focuses on developing.

　　一、热浸锌桥架的艺流程：

　　1、 The process of hot-dip galvanizing bridge:

　　热浸锌桥架的工艺流程如下:

　　The process flow of hot-dip galvanizing bridge is as follows:

　　表面处理:对桥架进行表面处理，表面的油污、锈蚀等杂质，确保镀锌层能够牢固附着在金属表面上。

　　Surface treatment: Surface treatment is carried out on the bridge frame to remove impurities such as oil stains and rust on the surface, ensuring that the galvanized layer can firmly adhere to the metal surface.

　　2.预处理:对桥架进行酸洗、水洗等处理，以去除表面的氧化物和其他杂质，为之后的镀锌工艺做好准备。

　　2. Pre treatment: Acid washing, water washing and other treatments are carried out on the bridge frame to remove surface oxides and other impurities, preparing for the subsequent galvanizing process.

　　3.镀锌槽:准备一个钢制槽，其中注入熔化的锌金属。这个镀锌槽需要加热到锌的熔点，通常为约450℃。

　　3. Galvanizing tank: Prepare a steel tank into which molten zinc metal is injected. This galvanizing tank needs to be heated to the melting point of zinc, usually around 450 ℃.

　　4.浸入镀锌槽:将经过预处理的桥架部件逐个浸入锌槽中。在浸入之前，还可以进行一次快速的酸洗和水洗，确保表面清洁。

　　4. Immersion in galvanizing tank: Dip the pre treated bridge components into the galvanizing tank one by one. Before immersion, a quick acid and water wash can be performed to ensure surface cleanliness.

　　5.恒温保持:将桥架部件在锌槽中恒温保持一段时间，以确保锌金属能够均匀地附着在表面上。

　　5. Constant temperature maintenance: Keep the bridge components at a constant temperature in the zinc bath for a period of time to ensure that the zinc metal can adhere evenly to the surface.

　　6.抽出镀锌:将已经完成镀锌的桥架部件逐个抽出锌槽，让多余的锌金属流下来，形成均匀的镀锌层。

　　6. Extraction of galvanizing: Extract the galvanized bridge components one by one from the zinc groove, allowing excess zinc metal to flow down and form a uniform galvanized layer.

　　7.冷却:将已经浸出的桥架部件放置在通风良好的地方，进行自然冷却，在冷却过程中，锌金属会逐渐固化，形成坚硬的锌层。

　　7. Cooling: Place the leached bridge components in a well ventilated area for natural cooling. During the cooling process, the zinc metal will gradually solidify, forming a hard zinc layer.

　　8.修整:在完成镀锌和冷却之后，一些不平整或不均匀的锌层进行修整过度厚的锌层进行修整，一般采用研磨或其他方法，将锌层修整到符合要求的厚度。

　　8. Trimming: After galvanizing and cooling, some uneven or uneven zinc layers are trimmed. Overly thick zinc layers are usually trimmed by grinding or other methods to achieve the required thickness.

　　热浸锌电缆桥架的使用优点：

　　Advantages of using hot-dip galvanized cable trays:

　　经热浸锌处理后，其锌层比电镀锌厚3倍以上，锌含量达95%，一般电镀锌会在几个月内出现生锈现象，而热浸锌电缆桥架却几年内都不会生锈。又因为其低于不锈钢、铝合金电缆桥架。是在强腐蚀环境下使用较高、性价比较高的一款电缆桥架。

　　After hot-dip galvanizing treatment, the zinc layer is more than three times thicker than electroplated zinc, with a zinc content of 95%. Generally, electroplated zinc will rust within a few months, while hot-dip galvanized cable trays will not rust for several years. Also, because its price is lower than that of stainless steel and aluminum alloy cable trays. It is a cable tray that is highly cost-effective and suitable for use in highly corrosive environments.

　　三、热浸锌电缆桥架标准：

　　3、 National standard for hot-dip galvanized cable tray:

　　热浸锌电缆桥架标准：

　　National standard for hot-dip galvanized cable tray:

　　常规热浸锌厚度≥65μm，加厚镀锌层可达到≥85μm（应符合检测标准：金属覆盖层钢铁制件热浸镀锌层技术要求及试验方法GB/T 13912-2002）。

　　The thickness of conventional hot-dip galvanizing is ≥ 65 μ m, and the thickness of thickened galvanized layer can reach ≥ 85 μ m (which should comply with the testing standard: Technical Requirements and Test Methods for Hot Dip Galvanized Layer of Metal Coating Steel Parts GB/T 13912-2002).

　　产品送检应符合标准：《T10216-2013 电控配电用电缆桥架》

　　The product inspection should comply with the standard: "T10216-2013 Cable Tray for Electrical Control and Distribution"
