Fig. 3 appearance of cast aluminum after natural color oxidation (local spot, uneven phenomenon) 2, film thickness measurement fluctuates greatly. Eddy current thickness gauge is normally used to gauge the thickness of oxide film. The measured value of the thickness gauge is suffering from the roughness, curvature of the substrate surface and the electrical properties of the measuring point. Used, because of the large and uneven surface roughness of die casting aluminum, the measured value is unstable and fluctuates greatly. If the top of product comes with an organic machined surface and the region of the machined surface is bigger than the area of the probe, the measured value will become more stable. If you have no machined surface, only some points on the rough surface can be measured and the typical value can be determined as qualified if the typical value is at the product range.
In line with the research of relevant scholars, adding cerium salt and lanthanum salt and other rare earth metals in the sulfuric acid electrolyte of Changshu anodizing can demonstrably increase the corrosion resistance and hardness of the coating, but the effect of adding cerium salt alone just isn't as effective as adding cerium salt and lanthanum salt at exactly the same time. When these complex rare earth metal salts are added, theIf the auxiliary complexing agents are added, the corrosion resistance of the coating won't be improved dramatically. Only when these rare earth metal auxiliary complexing agents are added at exactly the same time, the corrosion resistance of the coating can be dramatically improved. These auxiliary complexing agents are mainly organic acids. For alloy anodizing, the effect of organic acids on along with of the film should be thought about, particularly for the film requiring silver oxidation or light color, to be able to stop the color of the coating not pure or difficult to be light colored after dyeing. When Changshu aluminum surface treatment is oxidized by sulfuric acid solution, it could be seen that in the solution region close to the anode, this content of aluminum ions increases, oxygen is precipitated, and oxide film is formed, while hydrogen on the cathode, the forming of oxide film reflects the two steps at the same time. That is, the electrochemical film-forming process and chemical dissolution procedure for the oxide film.
jinyangalu Obviously, only when the film forming speed is more than the dissolution rate of the film, then a thickening of the oxide film is possible. As the resistance of the aluminum oxide film is extremely large, when its thickness reaches a specific limit, the resistance will hinder the continuation of the anode reaction, and the present won't pass through. At the moment, the film-forming speed is corresponding to zero and dissolves The clear answer process will not stop, and so the thickness of the formed oxide film is commonly thinner.
? aluminum alloy anode treatment is trusted in aerospace, military weapons, electronic, automobile parts, precision mechanical equipment, construction industry, aluminum windows and doors, and so forth? oxidation characteristics of die casting aluminum 1 . Compared with extruded aluminum, die casting aluminum has higher impurity content (e. g. ADC12, silicon content of 9. 5-12. 5%, copper content of 1. 5-3. 5%) 2These impurities can't be removed by traditional chemical pretreatment. Therefore , if the oxide film is formed on the surface of such material, you will see uneven, irregular, mottled and variegated phenomena.
curtain wall aluminium profiles Moreover, because silicon isn't conductive, the overall conductivity of the merchandise is poor. Underneath the same oxidation conditions, the looks of the film is significantly worse than that of extruded aluminum (as shown in the figure below). This really is also the characteristic of die casting aluminum oxidation.

Aluminum oxide and fluoride will be discharged along the way of production and processing, which will affect the pollination of crops, and the injury to human body and livestock also exists objectively. Aluminum oxidation waste gas treatment equipment uses the electrostatic power generated by high-voltage electric field to charge the waste gas in aluminum oxidation, and under the action of electric field, the charged dust is separated from the air flow, moved to the cathode and anode respectively and honored them, after which through the rapping device It's a dust removal device that vibrates and cleans the dust, so the accumulated dust falls into the ash hopper and achieves the purpose of waste gas treatment.
winG is a CMF designer with deep investment. When he asked for a draft, he was following up an anodic oxidation project for seven months. I asked, "so long? Seven months in the oxidation plant? " Wing said, "no! Oahu is the oxidation plant squatting here, a call, domineering call! " Really, really on the spot can't help but to overbearing wing about a domineering anodizing strategy. Yesterday, yesterday, he threw it overbearing. Every one, let us take a look. Domineering or not?
In summary, there are many new processes for aluminum and its own hard anode, nevertheless they are also challenged by various surface treatment options. It is expected that within the next 10 years, anodizing technology it's still the main surface treatment method, nevertheless the process technology ought to be improved continuously to occupy a dominant position in the long run. Aluminum in Changshu oxidation plant is a somewhat active metal with standard potential of -1. 66v. A layer of aluminum oxide film with thickness of about 0. 01-0. 1 μ M could be formed naturally in the air. The aluminum oxide film is amorphous, thin and porous, and has poor corrosion resistance. Nevertheless , if aluminum and its own alloys are placed in proper electrolyte and aluminum services and products are used as anode, aluminum oxide film is formed on the outer lining of aluminum services and products under the action of external current, this process is known as anodic aluminum oxidation.
