Problems solved by technology

[0005] Most of the existing aluminum profiles are treated by alkali etching, and the dissolution reaction of aluminum is necessary. At this time, under the condition of strong alkali, for the obvious rough extrusion lines, it takes a long time to corrode, resulting in aluminum consumption. Higher, poor sanding uniformity, poor bath stability, more sedimentation, affecting normal production

Abstract

The invention discloses a low-aluminum-consumption aluminum profile surface treatment process, and belongs to the technical field of aluminum profile surface treatment. The low-aluminum-consumption aluminum profile surface treatment process comprises the steps that an aluminum profile with the surface to be treated is hung on a bent frame; the aluminum profile is placed in a degreasing tank and subjected to ultrasonic cleaning and air drying, and a degreased aluminum profile is obtained; the degreased profile is subjected to mechanical sand blasting treatment; the treated profile is fed into an alkaline water tank to be subjected to alkaline etching treatment, and an alkaline treatment solution comprises NAOH, NA2CO3, NA3PO4, NA2SO4, an auxiliary agent and an additive; the profile subjected to alkali washing is washed twice, fed into a neutralization tank, and pickled with an acid treatment solution; and anodic oxidation treatment is carried out, then the profile enters a hole sealing tank, hole sealing treatment is carried out, after hole sealing is completed, the bent frame is hoisted for liquid drainage, and then the profile is washed and air-dried. After the treatment of the working procedures, the materials can be discharged; and then the qualified aluminum profile is packaged and stored according to the provisions, the required aluminum profile can be obtained, according to the low-aluminum-consumption aluminum profile surface treatment process, the surface difference is reduced, over-corrosion can be prevented, the service life of an alkali treatment tank is prolonged, aluminum consumption is reduced, and the surface treatment effect of the profile is improved.

Description

technical field [0001] The invention relates to the technical field of surface treatment of aluminum profiles, in particular to a surface treatment process for aluminum profiles with low aluminum consumption. Background technique [0002] Aluminum profile is currently a widely used material in construction, decoration, storage and other fields. It is widely accepted and used in people's life because of its light structure, corrosion resistance, raw materials that do not pollute the environment, and industrialized mass production. [0003] Therefore, aluminum profiles have become a more commonly used building material in people's lives and production. The world's aluminum output has surpassed copper output since 1956 and has always ranked first in non-ferrous metals. The current output and consumption of aluminum are second only to steel, becoming the second largest metal used by human beings; with the wide application of aluminum products. [0004] Most of the aluminum prof...
