热镀锌电缆桥架?以冷轧钢板制成，表面工艺为热镀锌，由槽式、托盘式或梯级式的直线段、弯通、三通、四通组件以及托臂（臂式支架）、吊架等构成具有密接支撑电缆的刚性结构系统之全称。在各种保护钢基体的涂镀方法中，热镀锌是非常优良的一种。它是在锌呈液体的状态下，经过了相当复杂的物理、化学作用之后，在钢铁上不仅镀上较厚的纯锌层，而且还生成一种锌一铁合金层。这种镀法，不仅具备了电镀锌的耐腐蚀特点，而且由于具有锌铁合金层。还具有电镀锌所无法相比拟的强耐蚀性。因此这种镀法特别适用于各种强酸、碱雾气等强腐蚀环境中。热镀锌的应用随着工农业的发展也相应扩大。因此，热镀锌制品在工业（如化工设备、石油加工、海洋勘探、金属结构、电力输送、造船等），农业（如：喷灌、暧房）、建筑（如：水及煤气输送、电线套管、脚手架、房屋等）、桥梁、运输等方面，近几年已大量地被采用。由于热镀锌制品具有外表美观、耐腐蚀性能好等特点，其应用范围越来越广泛。

　　Hot dip galvanized cable trays are made of cold-rolled steel plates and have a surface process of hot-dip galvanizing. They consist of straight sections, bends, tees, and tees in trough, tray, or step styles, as well as support arms (arm brackets), hangers, and other components to form a rigid structural system that tightly supports cables. 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. 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, heating rooms), 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.

　　Fireproof cable tray is suitable for laying indoor and outdoor overhead cable trenches and tunnels for power cables below 10KV, as well as control cables, lighting wiring, etc. The outer layer is coated with fire-resistant paint, which prevents the fire-resistant bridge from burning in case of fire, thus blocking the spread of fire. It has extremely good fire-resistant and fire-resistant effects, as well as being fire-resistant, oil resistant, corrosion-resistant, non-toxic, and pollution-free. The overall installation is convenient, the structure is reasonable, the service life is long, and it is beautiful. The cable is installed in the cable bridge, and the environment is clean and easy to clean. Fireproof coatings have the characteristics of thin coating, high fire resistance limit, and strong adhesion. Fireproof bridge is sprayed with a layer of fireproof paint on the surface of ordinary bridge to achieve the effect of fire prevention and flame retardancy! In fact, the cable tray itself does not catch fire, and only the cables can catch fire. The principle of fire prevention and flame retardancy played by fireproof paint is that fireproof cable trays can have a smooth surface and a frosted feel. They are generally used in the distribution lines of fire equipment, including fire control rooms, fire pumps, fire elevators, smoke exhaust fans, and fire automatic alarm systems. Except for the fire automatic alarm system, other distribution lines can use fire-resistant cables instead of fireproof cable trays. Fire resistant cable trays in underground garages require a fire resistance time of more than 1 hour. What is the difference between spray painted cable trays and fire-resistant cable trays? Spray painted cable trays and fire-resistant cable trays are both coated with a layer of paint on their surfaces, and there is basically no difference in appearance. The colors of both can be customized. (The above are some color models available for our factory's spray painted bridge and fireproof bridge. We can choose frosted or smooth surface, and the price may vary depending on the requirements. Due to the length of baking time and temperature, the color may be affected, and there may be some color difference.) The difference between them is that although they are very similar, the paint powder sprayed on them is different. The paint surface on the fireproof bridge is made of flame-retardant and fireproof materials, which are generally used in places with fire protection needs and have flame-retardant and fireproof properties. The electrostatic spray coating bridge is formed by electrolyzing a layer of organic plastic powder on the surface, which can enhance corrosion resistance and aesthetics, as well as waterproof, oil resistant, and anti-static properties.

　　热浸锌桥架热浸镀锌是延缓钢铁材料环境腐蚀的有效手段之一，它是将表面经清洗、 活化后的钢铁制品浸入600℃左右高温融化的锌液中，使钢构件表面附着锌层，锌层厚度对5mm以下薄板不得小于65μm，5mm及以上厚板不小于86μm。从而起到防腐蚀的目的。与?热浸锌其他金属防护方法相比，热浸镀锌工艺在镀层的物理屏障与电化学保护相结合的保护特性上，镀层与基体的结合强度上、镀层的致密性、耐久性、免维护性和经济性及其对制品形状与尺寸的适应性上，具有无可比拟的优势。目前热浸镀锌产品主要有钢板、钢带、钢丝、钢管等，其中热浸镀锌钢板所占比例。长期以来，热浸镀锌工艺因其低廉的施镀成本，优良的保护特性和漂亮的外观而备受人们的青睐，广泛应用于汽车、建筑、家电、化工、机械、石油、冶金、轻工、交通、电力、航空和海洋工程等领域。热浸锌桥架有什么优点呢？耐久年限长，生产工业化程度高，质量稳定。因而被大量用于受大气腐蚀较严重且不易维修的室外钢结构中。如大量输电塔、通讯塔等。近年来大量出现的轻钢结构体系中的压型钢板等。也较多采用热浸锌防腐蚀。热浸锌的首道工序是酸洗除锈，然后是清洗。这两道工序不彻底均会给防腐蚀留下隐患。所以必须处理彻底。对于钢结构设计者，应该避免设计出具有相贴合面的构件，以免贴合面的缝隙中酸洗不彻底或酸液洗不净。造成镀锌表面流黄水的现象。热浸锌是在高温下进行的。对于管形构件应该让其两端开敞。若两端封闭会造成管内空气膨胀而使封头板爆裂，从而造成事故。若一端封闭则锌液流通不畅，易在管内积存。由于热浸锌的工艺温度比较高，对回火温度较低的材料很容易使其在镀锌的过程中被退火，从而硬度降低。此外对配合件使用热浸锌还要考虑镀层的厚度对配合公差的影响。

　　Hot dip galvanizing is one of the most effective methods to delay environmental corrosion of steel materials. It involves immersing the cleaned and activated steel products in a molten zinc solution at around 600 ℃ to attach a zinc layer to the surface of the steel components. The thickness of the zinc layer should not be less than 65 μ m for thin plates below 5mm and 86 μ m for thick plates above 5mm. Thus achieving the purpose of corrosion prevention. Compared with other metal protection methods such as hot-dip galvanizing, the hot-dip galvanizing process has unparalleled advantages in the combination of physical barriers and electrochemical protection of the coating, the bonding strength between the coating and the substrate, the density, durability, maintenance free and economical properties of the coating, and its adaptability to the shape and size of the product. At present, hot-dip galvanized products mainly include steel plates, steel strips, steel wires, steel pipes, etc., among which hot-dip galvanized steel plates account for the largest proportion. For a long time, hot-dip galvanizing technology has been favored by people due to its low plating cost, excellent protective properties, and beautiful appearance. It is widely used in fields such as automobiles, construction, home appliances, chemicals, machinery, petroleum, metallurgy, light industry, transportation, electricity, aviation, and marine engineering. What are the advantages of hot-dip galvanized cable trays? Long durability, high degree of industrialization in production, and stable quality. Therefore, it is widely used in outdoor steel structures that are severely corroded by the atmosphere and difficult to maintain. Such as a large number of transmission towers, communication towers, etc. In recent years, there has been a significant increase in the use of profiled steel sheets in light steel structural systems. Hot dip galvanizing is also commonly used for corrosion prevention. The first process of hot-dip galvanizing is acid pickling and rust removal, followed by cleaning. Both of these processes are not thorough and can leave hidden dangers for corrosion prevention. So it must be dealt with thoroughly. For steel structure designers, it is advisable to avoid designing components with mating surfaces to prevent incomplete acid washing or incomplete cleaning of the gaps between the mating surfaces with acid solution. Causing the phenomenon of yellow water flowing on the galvanized surface. Hot dip galvanizing is carried out at high temperatures. For tubular components, both ends should be open. If both ends are closed, it will cause the air inside the pipe to expand and cause the head plate to burst, resulting in a safety accident. If one end is closed, the zinc liquid will not flow smoothly and is prone to accumulate inside the tube. Due to the high process temperature of hot-dip galvanizing, materials with lower tempering temperatures are easily annealed during the galvanizing process, resulting in a decrease in hardness. In addition, when using hot-dip galvanizing for mating parts, the influence of coating thickness on mating tolerances should also be considered.
