电缆桥架表面处理可以采取哪些方法?

电缆桥架是一种能保护电缆不受外界因素损坏的建筑材料,在现在的生活中电缆桥架已经到处都可以见到,比如地下停车场、超市、酒店等地方,但是还是有很多朋友对电缆桥架不是很了解,下面电缆桥架厂家就来给大家介绍一下电缆桥架的表面处理的方法有哪些。
Cable tray is a kind of building material that can protect cables from external factors. Cable tray can be seen everywhere in today's life, such as underground parking lots, supermarkets, hotels and other places, but many friends still don't know much about cable tray, The following cable tray manufacturers will introduce to you the surface treatment methods of cable tray.
电缆桥架的表面处理可以是:热浸镀锌,冷镀锌,静电粉末喷涂等。在热镀锌电缆桥架表面覆盖一层致密而厚的保护层。它完全避免钢与某些腐蚀性物质接触,保护钢材免受破坏。
The surface treatment of cable tray can be: hot dip galvanizing, cold galvanizing, electrostatic powder spraying, etc. The surface of hot-dip galvanized cable tray shall be covered with a dense and thick protective layer. It completely prevents the steel from contacting with some corrosive substances and protects the steel from damage.
新表面还产生锌盐,难以溶于水并且更具康复性。因此,海洋盐雾气氛中的一些项目也可以得到很好的保护。同时,加热工程中产生的铁锌混合物具有较高的耐磨性。有四种常用的镀锌方法:
The new surface also produces zinc salts, which are difficult to dissolve in water and more restorative. Therefore, some projects in marine salt fog atmosphere can also be well protected. At the same time, the iron zinc mixture produced in heating engineering has high wear resistance. There are four common galvanizing methods:
1、热浸镀锌:
1. Hot dip galvanizing:
热浸镀锌用作牺牲阳极以保护阴极金属。耐腐蚀性取决于镀锌层的厚度和腐蚀速率。热浸镀锌中锌层的厚度一般在65um(455g/m2)以上。锌和铁的组合表面形成一层锌合金,锌层增强附着力。在热浸镀锌中,很容易产生变形等。在电缆桥架和镀锌工艺中需要考虑它。
Hot dip galvanizing is used as sacrificial anode to protect cathode metal. Corrosion resistance depends on the thickness of zinc coating and corrosion rate. The thickness of zinc layer in hot-dip galvanizing is generally more than 65um (455G / m2). A layer of zinc alloy is formed on the combined surface of zinc and iron, and the zinc layer enhances the adhesion. In hot-dip galvanizing, deformation is easy to occur. It needs to be considered in cable tray and galvanizing process.
2、冷镀锌:
2. Cold galvanizing:
与热浸镀锌相比,工艺简单,成本低。电缆桥架的结构没有特殊要求。钝化处理后,镀锌镀锌的保护性能可大大提高。镀锌层通常约为12/zm。因此,它不适用于高耐腐蚀性的情况。
Compared with hot-dip galvanizing, the process is simple and the cost is low. There are no special requirements for the structure of cable tray. After passivation treatment, the protective performance of zinc plating can be greatly improved. The zinc coating is usually about 12 / ZM. Therefore, it is not suitable for high corrosion resistance.
3、粉末喷雾:
3. Powder spray:
喷涂材料一般为聚氯乙烯粉末,聚酯粉末或防腐蚀粉末。涂层的厚度约为100/1rn。静电喷涂具有外观美观,抗化学腐蚀性能好的特点。
Spraying materials are generally PVC powder, polyester powder or anti-corrosion powder. The thickness of the coating is about 100 / 1RN. Electrostatic spraying has the characteristics of beautiful appearance and good chemical corrosion resistance.
