冷镀锌电缆桥架是利用电解设备将电缆桥架经过除油酸洗、后放入成分为盐的溶液中，并连接电解设备的负极，在电缆桥架的对面放置锌版，连接在电解设备的正极接通电源，利用电流从正极向负极的定向移动就会在电缆桥架上沉积一层锌，冷镀电缆桥架是先加工后镀锌；锌层表面应光滑均匀，致密。不得有起皮、气泡、花斑、局部未镀、划伤等缺陷。

Cold galvanized cable tray is a method of using electrolytic equipment to remove oil and acid from the cable tray, then placing it in a solution containing salt, and connecting it to the negative electrode of the electrolytic equipment. A zinc plate is placed opposite the cable tray, connected to the positive electrode of the electrolytic equipment and connected to the power supply. The directional movement of current from the positive electrode to the negative electrode will deposit a layer of zinc on the cable tray. Cold galvanized cable tray is processed first and then galvanized; The surface of the zinc layer should be smooth, uniform, and dense. There must be no defects such as peeling, bubbles, spots, partial non plating, scratches, etc.

热镀锌电缆桥架：成品酸洗-水洗-加助镀液-烘干-挂镀-冷却-药化-清洗-打磨-热镀锌完工。是一种有效的金属防腐方式，主要用于各行业的金属结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中，使钢构件表面附着锌层，从而起到防腐的目的，一般可用于室外。

Hot dip galvanized cable tray: finished acid pickling - water washing - adding auxiliary plating solution - drying - hanging plating - cooling - medicating - cleaning - polishing - hot-dip galvanizing completed. It is an effective method of metal corrosion prevention, mainly used for metal structural facilities in various industries. It is to immerse the rust removed steel parts in a molten zinc solution at around 500 ℃, so that a zinc layer is attached to the surface of the steel components, thereby achieving the purpose of corrosion prevention. It can generally be used outdoors.

热喷锌涂层表面由分布均匀的锌粒组成，其粗糙程度对喷漆具有很好的附着力，使漆面不易脱落。同时又不会造成漆面不光滑而影响美观。热喷锌不会对工件造成变型。因为热喷锌只在工作表面产生瞬间高温，不会任何工件发生形变，喷涂应平整、光滑、均匀、不起皮、无气泡水泡。

The surface of the hot spray zinc coating is composed of evenly distributed zinc particles, and its roughness has good adhesion to the spray paint, making the paint surface less prone to peeling off. At the same time, it will not cause the paint surface to be uneven and affect the appearance. Hot spraying zinc will not cause deformation of the workpiece. Because hot spraying zinc only generates instantaneous high temperatures on the working surface and will not cause any deformation of the workpiece, the spraying should be flat, smooth, uniform, without peeling, and without bubbles or water bubbles.

热浸镀锌的托盘、桥架要求镀层表面均匀，无毛刺、过烧、挂灰、伤痕、局部未镀锌（直径2mm以上）等缺陷，不得有影响安装的锌瘤。螺纹的镀层应光滑，螺栓连接件应能拧入。桥架焊缝表面均匀，不得有漏焊、裂纹、夹渣、烧穿、弧坑等缺陷。

Hot dip galvanized trays and cable trays are required to have a uniform coating surface, without defects such as burrs, overburning, hanging dust, scratches, and partial non galvanizing (diameter of 2mm or more), and must not have zinc nodules that affect installation. The coating of the thread should be smooth, and the bolted connections should be able to be screwed in. The surface of the welding seam on the bridge should be uniform and free of defects such as missed welding, cracks, slag inclusion, burning through, and arc pits.

喷塑电缆桥架是将塑料粉末喷涂在电缆桥架上的一种表面处理方法。不需稀料，施工对环境无污染，对人体害；涂层外观质量优异，附着力及机械强度强；喷涂施工固化时间短；涂层耐腐耐磨能力高出很多；不需底漆；施工简便，对工人技术要求低；成本低于喷漆工艺；有些施工场合已经明确提出必须使用静电喷塑工艺处理；静电喷粉喷涂过程中不会出现喷漆工艺中常见的流淌现象。

Spraying plastic cable tray is a surface treatment method that sprays plastic powder onto the cable tray. No need for diluents, construction is pollution-free to the environment and non-toxic to human health; The coating has excellent appearance quality, strong adhesion and mechanical strength; Short curing time for spray painting construction; The corrosion resistance and wear resistance of the coating are much higher; No primer required; Easy construction with low technical requirements for workers; The cost is lower than the painting process; Some construction scenarios have explicitly stated that the use of electrostatic spraying technology is necessary for treatment; During the electrostatic powder spraying process, there will be no common flowing phenomenon in the painting process.

防火电缆桥架外观与喷塑电缆桥架比较相似，不过性能完全不同，防火电缆桥架主要性能是防火，有一定的防火等级，常用于有防火要求的场所，表面粗糙，表面摸起来会有粗糙斜斜的感觉，当遇到火灾后不会燃烧，并且可以阻隔火势继续蔓延下去，起到一定的防火作用，防火涂层可以针对施工环境设计去选择桥架的颜色。

Fireproof cable trays have a similar appearance to spray painted cable trays, but their performance is completely different. Fireproof cable trays mainly have fire resistance, with a certain fire rating, and are commonly used in places with fire protection requirements. The surface is rough, and there is a rough and inclined feeling when touched. When encountering a fire, it will not burn and can block the fire from continuing to spread, playing a certain role in fire prevention, Fireproof coatings can be designed to choose the color of the bridge according to the construction environment.
