Problems solved by technology

The invention forms a layer of protective film on the surface of the aluminum strip, which has the functions of insulation, acid and alkali resistance, and anti-aging. The reel aluminum strip formed by the invention can be installed and used after being processed into aluminum products at the construction site, which solves the problem of the prior art The problem of inconvenient transportation exists in the surface treatment of aluminum strips after forming aluminum products. The waste materials can be reused in the production process, which greatly reduces the discharge and waste of liquid materials such as waste acid. The loss rate of aluminum strips is low, and it is environmentally friendly. Advantages of energy saving and low consumption

Abstract

The invention discloses a surface treatment technology of a reel aluminium strip, comprising the following technological steps of: chemically polishing the aluminium strip; washing the polished aluminium strip; cooling-passivating the washed aluminium strip; washing the passivated aluminium strip; oxidizing the washed aluminium strip; washing the oxidized aluminium strip; passivating the washed aluminium strip secondarily to form a passivation film on the surface of an oxide film; washing the passivated aluminium strip to remove acidizing fluid on the aluminium strip; conducting high-temperature hole-sealing on the washed aluminium strip to seal holes on the oxide film so as to form a protective film on the surface of the aluminium strip; dragging the reel aluminium strip after high-temperature hole-sealing, and reeling the strip to form a finished reel aluminium strip. The invention has the functions of insulation, acid and alkali resistance and ageing resistance. The formed reel aluminium strip can be installed for use after being processed to be an aluminium product in a construction site, therefore, the invention solves the problem of inconvenient transportation when the aluminium strip is subjected to surface treatment after forming the aluminium product in the prior art.

Description

technical field [0001] The invention relates to a process for treating the surface of an aluminum strip, in particular to a surface treatment process for a reel aluminum strip. Background technique [0002] In the prior art, when preparing aluminum alloy doors and windows, in the usual method, the aluminum strip is first stamped into a corresponding molded part, and then further surface layer pretreatment and coating are carried out on the molded part, that is, the aluminum strip is prepared first, Then the aluminum strip is cut to length and shaped into molded parts, and then the molded parts are surface treated. For example, in the production of aluminum alloy door pieces, the aluminum strip is first cut to length and shaped into a door piece, and then traditionally polished and oxidized. Using the existing preparation process, every ton of product needs to consume 3-5 kg ​​of aluminum. In addition, 220 kg of sulfuric acid, 20 kg of nitric acid, and 60 kg of phosphoric ac...
