一般來說鋁皮的密度比較一小，所以質(zhì)量也比較輕。所以，鋁皮非常容易加工和操作。這也是這么多年來鋁皮在保溫行業(yè)銷量一直領(lǐng)先的原因，毫不客氣的來說現(xiàn)在管道保溫鋁皮基本上完全代替了鐵皮。那么鋁皮現(xiàn)在這么火熱。
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.
鋁皮的耐腐蝕性主要表現(xiàn)在以下方面：
The corrosion resistance of aluminum sheet is mainly shown in the following aspects:
1、純鋁皮的密度比較輕，純度越高的鋁皮與空氣接觸氧化的反應(yīng)也會越大，表面會形成一種很薄、很致密的氧化膜。而且通常來說要比其他金屬化學(xué)反應(yīng)要快一些，薄膜的厚度也要厚一些，這層薄膜能夠較好避免內(nèi)部組織和空氣中的微生物和水分進(jìn)行接觸。
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、鋁皮的機(jī)械強(qiáng)度，我們會發(fā)現(xiàn)，鋁皮的耐腐性越強(qiáng)，它的機(jī)械強(qiáng)度就會越低，那么為了更好的解決這一問題，可以在鋁皮中添加微量的稀有元素，例如：錳、鎂等元素。這樣不僅增加了鋁皮的硬度，而且使它的機(jī)械強(qiáng)度變得大一點(diǎn)，大大的增加了它的耐腐蝕性。

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、鋁皮的粉末涂裝，也就是咱們常說的彩涂鋁皮，可以有各種顏色供大家挑選，添加了鋁皮的漂亮性能，不過根據(jù)小編觀察，管道保溫用彩涂鋁皮的還比較小，因?yàn)槌杀緝r格會增加，除非客戶有指定要求的。
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.
