一般来说铝皮的密度比较一小，所以质量也比较轻。所以，铝皮非常容易加工和操作。这也是这么多年来铝皮在保温行业销量一直领先的原因，毫不客气的来说现在管道保温铝皮基本上完全代替了铁皮。那么铝皮现在这么火热。
Generally speaking, the density of aluminum skin is relatively small, so the quality is lighter. Therefore, the aluminum skin is very easy to process and operate. This is also the reason why aluminum skin has been in the lead in the heat preservation industry for many years, and it is unkind to replace the iron skin in the pipeline. So the aluminum skin is so hot now.
铝皮的耐腐蚀性主要表现在以下方面：
The corrosion resistance of aluminum sheet is mainly shown in the following aspects:
1、纯铝皮的密度比较轻，纯度越高的铝皮与空气接触氧化的反应也会越大，表面会形成一种很薄、很致密的氧化膜。而且通常来说要比其他金属化学反应要快一些，薄膜的厚度也要厚一些，这层薄膜能够较好避免内部组织和空气中的微生物和水分进行接触。
1, the density of pure aluminum skin is relatively light, the higher the purity of aluminum skin and air contact oxidation reaction will be greater, the surface will form a very thin, very compact oxide film. And usually it is faster than other metal chemical reactions, and the thickness of the film is a little thicker. This film can better avoid contact between the microorganism and the moisture in the air.
2、铝皮的机械强度，我们会发现，铝皮的耐腐性越强，它的机械强度就会越低，那么为了更好的解决这一问题，可以在铝皮中添加微量的稀有元素，例如：锰、镁等元素。这样不仅增加了铝皮的硬度，而且使它的机械强度变得大一点，大大的增加了它的耐腐蚀性。

2, the mechanical strength of aluminum skin, we will find that the stronger the corrosion resistance of the aluminum skin, the lower the mechanical strength, then in order to better solve this problem, you can add a trace of rare elements in the aluminum skin, such as manganese, magnesium and other elements. This not only increases the hardness of the aluminum skin, but also increases the mechanical strength of the aluminum skin, greatly increasing its corrosion resistance.
3、铝皮的粉末涂装，也就是咱们常说的彩涂铝皮，可以有各种颜色供大家挑选，添加了铝皮的漂亮性能，不过根据小编观察，管道保温用彩涂铝皮的还比较小，因为成本价格会增加，除非客户有指定要求的。
3, the powder coating of aluminum skin, that is, we often say color coating aluminum skin, can have various colors for everyone to choose, add the beautiful performance of aluminum skin, but according to the small editor, the pipe insulation color coating aluminum skin is still relatively small, because the cost price will increase, unless the customer has the specified requirements.
