乐从钢材市场渗铝板冷却塔铝合金板声屏障用热镀锌钢板

金属声屏障的材料包括铝合金板、镀锌板、铁板等。铁板很容易在潮湿的空气中氧化生锈，在生产和使用过程中造成不便，所以铁板人们很少采用。镀锌板以其优良的性能和适中的价格比，被广大客户接受。

The materials of the metal sound barrier include aluminum alloy plate, galvanized plate, iron plate, etc. Iron plate is easy to oxidation and rust in humid air, in the process of production and use of inconvenience, so people rarely use iron plate. Galvanized sheet with its excellent performance and moderate price ratio, is accepted by the majority of customers.

铝合金板也称镀铝钢板，也有人称之为渗铝板或热浸渗铝板，其中铝含量为90%，硅10%。其它元素还有铜、镁、锌、锰等。镀铝比镀锌更具优越性，镀铝层不仅具有比镀锌层好得多的耐蚀，而且还有良好的耐高温氧化性，这些都是镀锌层所比不上的。由于镀铝钢板的性能优越，已被广泛应用于我们的日常用品之中，如汽车消声器、家用电器等。

Aluminum alloy plate is also known as aluminum plating steel plate, also called seepage aluminum plate or hot soaking aluminum plate, the aluminum content is 90%, silicon 10%. Other elements include copper, magnesium, zinc, manganese and so on. Aluminization is more superior than galvanized layer. Aluminized layer not only has much better corrosion resistance than galvanized layer, but also has good high temperature oxidation resistance, which are not comparable to galvanized layer. Due to the superior performance of aluminum plating steel plate, it has been widely used in our daily supplies, such as automobile muffler, household appliances, etc.

 铝合金板的表面易自然生产一层致密牢固的AL2O3保护膜，这层保护膜能很好的保护基体不受腐蚀。通过人工或机器喷涂后，能很好的着色，可以保持20年不褪色，所以采用铝合金板制作的冷却塔声屏障使用寿命更长久。

The surface of aluminum alloy plate is easy to naturally produce a layer of dense and firm AL2O3 protective film, this protective film can well protect the matrix from corrosion. After manual or machine spraying, it can be very well colored and can be kept fast for 20 years, so the sound barrier of the cooling tower made of aluminum alloy plate has a longer service life.
