虽然我们都知道电缆桥架中使用的材料不易生锈,但长时间不能承受室外使用,它仍会生锈,这种锈蚀是必要条件,让我们介绍一下桥梁以下主要生锈条件:
Although we all know that the materials used in the cable tray are not easy to rust, they will still rust if they can not withstand outdoor use for a long time. This corrosion is a necessary condition. Let's introduce the following main rust conditions of the bridge:
首先,桥梁由铁制成,铁很容易生锈。除了其化学性质外,它还与外部条件有关。这就是我们经常称之为生锈的东西。
First of all, bridges are made of iron, which is easy to rust. In addition to its chemical properties, it is also related to external conditions. This is what we often call rust.
二,生锈:
2、 Rust:
水分是使铁易生锈的物质之一。当空气中的氧气溶解在水中时,氧气在水环境中与铁反应,而称为氧化铁的氧气是生锈的。
Moisture is one of the substances that make iron rust easily. When the oxygen in the air is dissolved in water, the oxygen reacts with iron in the water environment, and the oxygen called iron oxide is rusty.
2,铁锈是一种棕红色的物质,很容易脱落,一块铁完全生锈,体积可以膨胀8倍。如果没有去除锈迹,海绵生锈特别容易吸收水分,铁会更快燃烧。
2. Rust is a brownish red substance, which is easy to fall off. A piece of iron is completely rusted, and its volume can expand 8 times. If the rust is not removed, the sponge will rust and absorb water easily, and the iron will burn faster.
三,除锈:
3、 Rust removal:
它可以用各种工具铲掉,也可以溶解在酸性溶液中。
It can be removed with various tools or dissolved in acidic solution.
2.去除锈后,一定要对铁的表面进行处理,涂上一层铅丹,然后涂上。或镀有其他不易生锈的金属。
2. After removing rust, the iron surface must be treated, coated with a layer of lead, and then coated. Or plated with other metal that is not easy to rust.
3.更彻底的方法是在熨斗中加入一些其他金属来制造不锈钢合金。我们熟悉的不锈钢是通过在钢中添加少量镍和铬而制成的合金。
3. A more thorough method is to add some other metals to the iron to make stainless steel alloy. The familiar stainless steel is an alloy made by adding a small amount of nickel and chromium to the steel.
电缆托架可以连接到各种建筑物和管架支架上。在每个人都了解生锈条件后,我们可以提前预防。这不会影响桥梁的正常使用。如果维护良好,可以延长使用寿命。
Cable trays can be connected to various buildings and pipe rack supports. After everyone knows the rust conditions, we can prevent it in advance. This will not affect the normal use of the bridge. If well maintained, the service life can be extended.
