什么是热镀锌电缆桥架?

热镀锌桥架是将防锈处理后的钢构件浸入600℃左右高温融化的锌液中,使钢构件表面粘附锌层,锌层厚度对5mm以内薄板不可低于65μm,对厚板不小于86μm,从而具有耐腐蚀性的目的。作为一种合理有效的金属防腐方法,热浸锌工艺已被普遍用作各行业的金属结构设施上,耐腐蚀性年限达到十年以上。
Hot dip galvanized bridge is to immerse the steel members after rust prevention treatment into the molten zinc at a high temperature of about 600 ℃, so as to make the surface of the steel members adhere to the zinc layer. The thickness of the zinc layer shall not be less than 65 for thin plates within 5mm μ m. Not less than 86 for thick plate μ m. Thus, it has the purpose of corrosion resistance. As a reasonable and effective method of metal corrosion prevention, hot-dip galvanizing process has been widely used in metal structures and facilities in various industries, and its corrosion resistance has reached more than ten years.
1. 什么是热镀锌电缆桥架
1. What is hot galvanized cable tray
以冷轧钢板制作而成,表面工艺为热镀锌,由槽式、托盘式或梯阶式的直线段、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。
It is made of cold-rolled steel plate, and the surface process is hot-dip galvanization. It is the full name of a rigid structural system with closely connected supporting cables, which is composed of trough type, tray type or ladder type straight sections, elbow, tee, cross components, corbel (arm support), hanger, etc.
2. 热镀锌桥架的原理是什么
2. What is the principle of hot galvanized cable tray
热镀锌层是锌在高温液态下,分3个流程产生的:
The hot-dip galvanized layer is produced by three processes under the high-temperature liquid state of zinc:
(1)铁基表层被锌液融解产生锌—铁合金相层。
(1) The surface layer of iron base is melted by liquid zinc to produce zinc iron alloy phase layer.
(2)合金层中的锌离子进一步向基体扩散产生锌铁互溶层。
(2) Zinc ions in the alloy layer further diffuse to the matrix to produce a zinc iron miscible layer.
(3)合金层表层包络着锌层。
(3) The surface of the alloy layer is surrounded by a zinc layer.
3. 热镀锌桥架的性能特点
3. Performance characteristics of hot-dip galvanized Bridge
(1)有着偏厚的紧密的纯锌层覆盖在钢铁表面上,它能够 防止钢铁基体与任何的腐蚀溶液的接触,维护钢基体免遭腐蚀。在平常空气中,锌层表面形成一层很薄而密实的氧化锌层表面,它难以溶于水,故对钢基体起着一定维护功能。如果氧化锌与空气中其他的成分生成不溶性锌盐后,则防蚀功能更理想。
(1) It has a thick and close pure zinc layer covering the steel surface, which can prevent the steel substrate from contacting with any corrosion solution and maintain the steel substrate from corrosion. In normal air, a thin and dense zinc oxide layer is formed on the surface of the zinc layer, which is difficult to dissolve in water, so it plays a certain maintenance function on the steel matrix. If zinc oxide and other components in the air form insoluble zinc salts, the anti-corrosion function is more ideal.
(2)有着铁—锌合金层,紧密结合,在海洋性盐雾空气及工业性空气中表现抗腐蚀性。
(2) It has an iron zinc alloy layer, which is closely combined and shows corrosion resistance in marine salt spray air and industrial air.
(3)因为结合稳固,锌—铁互溶,有着较强的耐磨性能。
(3) Because the combination is stable, zinc iron is miscible, and has strong wear resistance.
(4)因为锌有着优良的延展性,其合金层与钢基附着稳固,因而热镀件可进行冷冲、轧制、拉丝、弯曲等各种各样成型而不损坏镀层。
(4) Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base, hot-dip plated parts can be formed by cold stamping, rolling, wiredrawing, bending and other forms without damaging the coating.
(5)钢结构件热镀锌后,等同于一次退火处理,能合理有效改进钢基体的机械性能方面,清除钢件成型焊接时的应力,有益于对钢结构件进行车削加工。
(5) After hot galvanizing of steel structure, it is equivalent to one-time annealing treatment, which can reasonably and effectively improve the mechanical properties of steel matrix, remove the stress during steel forming and welding, and is beneficial to turning of steel structure.
(6)热镀锌后的件表面明亮美观大方。
(6) The surface of hot-dip galvanized parts is bright and beautiful.
(7)纯锌层是热镀锌中具有塑性的一层镀锌层,其特性基本上贴近于纯锌,有着延展性,因而它富有挠性。
(7) Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its characteristics are basically close to pure zinc and have ductility, so it is flexible.
