Method for eliminating tin-nickel dual-salt electrolytic coloring aberration of aluminum profile

Abstract

The invention discloses a method for eliminating tin-nickel dual-salt electrolytic coloring aberration of an aluminum profile, which comprises the following steps of: setting the running speed of a travelling trolley above a tin-nickel dual-salt electrolytic tank body to be 0.8-1.0m / s in a vertical direction, 0.8-1.0m / s in a horizontal direction after the aluminum profile is subjected to electrolytic coloring in a tin-nickel dual-salt electrolytic tank; and controlling the aluminum profile subjected to electrolytic coloring to be shifted to a rinsing tank according to the running speed, and cleaning acid liquid on the surface of the aluminum profile to eliminate color aberration of the aluminum profile. By accelerating a shift speed of the aluminum profile after coloring, the shift time of hanging the aluminum profile by the travelling trolley is shortened, so that the aluminum profile can be rapidly shifted to the rinsing tank to clean the acid liquid on the surface, and is prevented from fading, and the problem of color aberration generated during tin-nickel dual-salt electrolytic coloring of the aluminum profile on a vertical oxide line is solved. The method is simple and convenient to implement, is easy to control, and is suitable for production and application on a large scale.

Description

technical field [0001] The invention relates to the field of electrolytic coloring of aluminum profiles, in particular to a method for eliminating the color difference of tin-nickel double salt electrolytic coloring of aluminum profiles. Background technique [0002] At present, in the aluminum profile industry, there will be a large color difference between the upper and lower ends of the aluminum profiles produced by the vertical oxidation line tin-nickel double salt electrolytic coloring tank, and most of the profiles are light in color at the upper end and dark at the lower end. Electrophoretic coating of profiles After the color difference is more obvious, a large amount of waste products will be produced, which will bring great waste to production. In the prior art, tin-nickel double-salt electrolytic coloring tanks are used on the vertical oxidation line to solve the problem of color difference between the upper and lower ends of the profile: (1) Saw part of the lower...
