An anodic oxidation tank and brightening technology of strip-series aluminum alloy section bars

Abstract

The invention relates to an anodic oxidation tank and brightening technology of strip-series aluminum alloy section bars. The device includes an electrolytic tank body, cathodic conductive devices and anodic conductive devices. Interconnected coiling heat exchangers are installed in the sidewalls and the bottom board of the electrolytic tank body which is in clamping connection with the cathodic conductive devices through notches. The device comprises three pairs of anodic conductive devices. Each pair is separately and fixedly arranged on two opposite inner walls of the electrolytic tank body. From the top to the bottom, the three pairs of anodic conductive devices have a hollow inner octagonal structure, an inner hexagonal structure and an inner pentagonal structure. The brightening technology includes a step of self-checking and placement, a step of oil removing and washing, a step of chemical brightening and washing, a step of neutralization bright dipping and washing, a step of anodic oxidation and washing, a step of hole sealing, washing and drying and a step of dismounting, checking and packaging. The anodic oxidation tank of strip-series aluminum alloy section bars has excellent conductive performance, can effectively enhance the uniformity of the surface quality of strip-series aluminum alloy section bars, can effectively reduce the waste of raw materials and is suitable for extensive popularization and application.

Description

technical field [0001] The invention relates to the technical field of strip-based aluminum alloy profiles processing, in particular to an anodic oxidation tank and a brightening process for strip-based aluminum alloy profiles. Background technique [0002] Decorative doors, windows or curtain walls in modern society are mainly made of aluminum alloy profile structure materials. The main disadvantages of this profile are single appearance and easy to corrode when exposed to the air for a long time. Individual requirements for decorative structural materials. In order to optimize the decorative effect of aluminum alloy profiles, enhance their corrosion resistance and prolong their service life, aluminum alloy profiles generally require surface treatment. The surface treatment of aluminum alloy profiles is a perfect squeeze of aluminum alloy profiles and a gorgeous turn in modern society. The commonly used surface treatment method for aluminum alloy profiles is anodic oxidati...

AI Technical Summary

Problems solved by technology

However, the general anodic oxidation treatment device for aluminum alloy profiles has certain instability in the clamping connection with the aluminum alloy profiles to be oxidized or the problem of uneven heating or cooling of the electrolyte by the equipment, which makes it easy for this equipment to do The surface quality of the produced aluminum alloy profiles is uneven, which is difficult to meet the consumption needs of consumers
