铜门在出厂时，都是光华亮丽的，她华丽的外表也是吸引众人的重要原因之一。但是，在使用一段时间后，会发生什么样的变化呢？我们又应该怎样处理呢？

Copper doors are always radiant and beautiful when they leave the factory, and their gorgeous appearance is also one of the important reasons that attract people. But what kind of changes will occur after using it for a period of time? How should we handle it?

铜门的原材料是什么

What are the raw materials for copper doors

铜门的原材料当然是铜啦！铜，是很难发生氧化反应的，所以一般的铜门是不太会出现生锈的状况，这要比其他的金属门（铁材质、钢材质）要强的多。

The raw material for copper doors is of course copper! Copper is difficult to undergo oxidation reactions, so general copper doors are less likely to rust, which is much stronger than other metal doors (made of iron or steel).

但是一些铜门选用的是锌合金内架，做成的锌合金铜门，这样的铜门在经过日晒雨淋后，其内部就很容易发生腐蚀的状况。锌这种金属的活动性太强，极易与空气发生氧化反应，而经过雨水作为介质的话，就会加速他的内部腐蚀情况，这样会造成铜门的整个结构不稳定，强度不够，铜门的防盗性能也大大地降低。因此在选择铜门时，一定要认准选择镀锌钢管的域昌铜门。

However, some copper doors use zinc alloy inner frames, which are made of zinc alloy copper doors. Such copper doors are prone to corrosion inside after being exposed to sunlight and rain. Zinc, a metal with strong activity, is prone to oxidation reactions with air. If it is used as a medium by rainwater, it will accelerate its internal corrosion, causing instability and insufficient strength of the entire structure of the copper door. The anti-theft performance of the copper door is also greatly reduced. Therefore, when choosing a copper door, it is important to identify the Yuchang copper door that uses galvanized steel pipes.
