Embodiment Construction

[0021] The following will be described in detail in conjunction with the embodiments of the present invention.

[0022] A process for cleaning, spraying and curing aluminum profiles, characterized in that it comprises the following steps:

[0023] (1) Degreasing:

[0024] At room temperature, soak the aluminum profile in a phosphoric acid solution with a mass fraction of 80% for 5-10 minutes, and then soak it in a 1mol / L Na2CO3 solution for 5-10 minutes;

[0025] (2) High pressure washing:

[0026] Take out the aluminum profile and rinse the surface of the aluminum profile with a high-pressure water gun for 1 hour;

[0027] (3) Anodizing:

[0028] The washed aluminum profile is placed in a 98% H2SO4 solution as an anode, and an external current is applied to oxidize the anode to passivate the surface of the aluminum profile to form an oxide film with a thickness of 5-20 μm;

[0029] (5) High pressure washing:

[0030] Take out the aluminum profile and rinse the surface of...

Abstract

The present invention is a cleaning and spraying curing process for aluminum profiles, which is characterized in that it comprises the following steps: (1) degreasing; (2) high-pressure water washing; (3) anodic oxidation; (5) high-pressure water washing; (6) spraying; (7) ) solidified. The cleaning, spraying, and curing process for aluminum profiles according to the invention has the advantages of thorough cleaning, uniform spraying, good curing effect, not easy to drop paint, and good surface smoothness.

Description

technical field [0001] The invention relates to the field of cleaning and spraying of aluminum profiles, in particular to a process for cleaning, spraying and curing of aluminum profiles. Background technique [0002] The aluminum profile titanium plating process belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The aluminum profile process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. [0003] The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good effect. The hardness of the film layer is HV≈1500, and it is 150 times more wear-resistant than 22K gold plating under the same conditions. It can be processed into a variety of bright alum...
