Anodized aluminum----Aluminum Classification and production process
With the extensive application of the rapid development of economic construction and aluminum products , domestic aluminum industry has made considerable achievements impressive , aluminum rolled products , aluminum flat rolled production has also been greatly improved. Although aluminum has filled in all aspects of our lives , but for how aluminum sheet classification and how to make a lot of people still know better than less .
Generally, we say aluminum is just a term referring to the choice of aluminum or aluminum alloy material made of aluminum plate material , Atotech production has brushed aluminum, anodized aluminum plate , embossed aluminum , aluminum mirror and so on. Classification of aluminum is aluminum by different processing methods used in the production process of the decision. To the flat aluminum plate made of aluminum embryos by heating , rolling, straightening solution and aging heat and other processes made of.
First, embossed aluminum :
Embossed aluminum processing such as rolling is performed on the basis of aluminum , the aluminum surface is formed such that a wide range of aluminum pattern . Embossed aluminum is mainly used in packaging, integrated ceiling , building walls and so on.
Second, brushed aluminum:
Brushed aluminum main process has three parts , namely, degreasing , sand mills and water. Brushed aluminum material in the production process, the first use of repeated rubbing sandpaper lines , handling finished aluminum surface will clearly show a fine wire traces roots to achieve the brushed metal effect , and then they would go through the anode deal , which would generate a film layer containing a special metal components in aluminum surface , can play a role in anti-corrosion protection . Taiwan's leading aluminum surface pretreatment enterprises - Shanghai Atotech Aluminum Co., Ltd. , also decorated according to different needs , will produce a silk pattern ruled, random pattern , thread , ripple, spin lines and other lines .
Third, anodized aluminum plate :
Anodized aluminum plate to be formed through a process of electrolytic oxidation. First of all to the aluminum plate as an anode in the electrolyte , and under certain conditions the current through the electrolytic oxidation , and finally to a thin alumina layer formed on the aluminum surface . It sounds so simple, but in fact the ordinary general domestic aluminum oxide production processes used by enterprises , technology is more complex, and the defective rate is relatively high. Atotech as a leading enterprise in the aluminum surface pretreatment , after continuous technological innovation , and finally achieve the production process of continuous volume pressure oxidation. Not only shorten the anodized aluminum plate process, but also greatly improve the production efficiency and product yield . Is by far , the first use of a continuous roll pressure oxidation process manufacturers.
Fourth, mirror aluminum :
Aluminum mirror needs to be processed by a variety of methods rolling technology, and grinding , etc., in order to make the aluminum surface showing a mirror effect. Mirror aluminum production in developed countries are generally used method to manufacture the rolling of coils , and domestic technology development is lagging behind , there is only one company Atotech which uses rolling technology can provide a mirror made of aluminum coils .
Aluminum through different processing methods can form a variety of aluminum, and excellent processing method also determines whether or not the effect is good or bad quality aluminum and grade level .
