Industrial Aluminium Profile after chemical polishing surface rough phenomenon
Industrial Aluminium Profile after chemical polishing on the surface of the rough phenomenon may be due to the nitrate content of the bath is too high, caused by acid erosion; the other hand, the aluminum may be caused by internal defects in the surface roughness.
If the copper content in the bath is also high, the surface roughness will be more serious. Usually if the nitric acid content of the bath is too high, chemical polishing reflects the intense, "boiling" phenomenon. If the nitric acid content is normal, copper content is high, then the surface of the industrial aluminum after the water is attached to a layer of very obvious characteristics of metallic copper color. If the copper color is very deep, the copper content in the surface bath is high, and measures should be taken to adjust the nitric acid and copper content to the normal range.
If the copper content of the additive is less, if the copper in the bath comes from the chemical polishing of the copper-containing aluminum material, take measures to add the additive or adjust the bath without copper.
If the internal aluminum alloy tissue defects caused by surface roughness: casting state organization, such as casting or die-casting of aluminum parts; aluminum grain refinement is not sufficient and loose, slag and other defects; deformation of the process is not sufficient, And other defects caused by rough surface, you can improve the quality of aluminum to prevent. Therefore, the industrial aluminum production process to improve the surface quality of chemical polishing is particularly important.
1. When selecting the appropriate profile series, you need to consider the expected maximum load of the profile, by calculating the stress caused by bending and material strain, and considering the appropriate safety margin to determine the correct size of the profile. For low-load areas, "lightweight" profiles and "E" series profiles can be used to ensure that all components are used in a manner that is not only cost-effective but also capable of withstanding the required stresses.
2, when the installation of additional accessories should avoid the profile of the fracture, this is better stability, less incision, less connection, and shorten the installation time. The profile is extended only by the aid of the associated fastening element and, if possible, Industrial Aluminium Profilethe element is supported at the connector.
3, the slot width of 6 mm series of industrial aluminum for all types of light frame combination structure. By selecting the profile 6 series or profile 6 series light for specific construction tasks looking for the most suitable material.
4, with a closed slot profile for the appearance of the emphasis on the structure, when used in combination with the radial seal, especially for dust-free applications.
5, the end cover for a variety of sections of the profile,Industrial Aluminium Profile the shear side without chamfering deburring. The plastic end cap is secured to the center hole by pressing and opening it. This special cone can prevent vibration, and can also resist the effects of temperature changes.
6, fasteners product group components to ensure that the strong locking profile connection with excellent fastening. The fastening of all fastening elements is very flexible, which in the future has a special advantage of changing the structure, easy to expand or shrink the size.
