[Alcoa.com] A widely used kneading process in aluminium profiles. His use plays an important role in aluminum profiles and is favored by many companies. It is used in the manufacture of aluminum profiles in aluminium. During the kneading of the profiles, there are some small particles on the appearance of the profiles that are adsorbed on the appearance of the profiles, and the touch of the hands touches them, which affects the oxidation and reduces the production power and the yield. What are the reasons for these small particles? 7075 aluminum ribbon There are more and more methods for the appearance treatment of aluminum profiles. In addition to the usual oxide profiles, electrophoretic profiles, spray profiles, fluorocarbon spray profiles, and wood grain paint profiles have been presented in succession. The lack of "adsorbent particles" has little effect on the usual oxidized materials, but it has a great influence on other forms of disposal, mainly on the appearance of these profiles. In the production of the aluminum profiles, the “adsorption particles†of the extruded profiles are carefully observed or slid by hand on the appearance of the profiles, and the adsorbed particles are found. In the sawing and packaging process, most of the small particles can be removed, but still some are still adsorbed on the appearance of the profiles due to electrostatic forces. After aging treatment, these particles adhere more closely to the appearance of the profiles. In the pre-disposal process of profile appearance, some of them can be removed due to the influence of the bath concentration, but a small pit is formed on the appearance of the profile. This problem is often seen in the production of electrophoretic and spray profiles. For the manufacture of a high-quality aluminum profile, small particles are enough to affect his entire, and sometimes constitute the composition of waste, together with the impetus. In the production of aluminum profiles to find out his reasons to reduce its impact on the quality of aluminum profiles, aluminum profiles will increase his production power, reduce scrap rate, decline in the dross of the country's available power.
