Problems solved by technology

[0002] In the production process of aluminum profiles, it is necessary to clean the aluminum profiles before spraying. During the production and processing of aluminum profiles, grease and dust are inevitably attached to the surface. If they are not cleaned, the aluminum profiles after spraying are easy to be corroded. , Corrosion, affecting the quality of aluminum profiles, the existing aluminum profile cleaning method is relatively simple, the cleaning effect is very poor, resulting in paint falling off and corrosion of aluminum profiles in a short time after spraying

Embodiment Construction

[0017] The invention discloses a cleaning process for aluminum profiles, which comprises the following steps:

[0018] 1) Soaking: Soak the aluminum profile in clean water with a water temperature of 50°C for 5-10 minutes;

[0019] 2) Scrubbing: Then take out the soaked aluminum profile, brush the surface of the aluminum profile with a brush and rinse with water at the same time;

[0020] 3) Degreasing: Put the aluminum profile into the degreasing agent bath at 23°C, soak for 4 minutes, and keep stirring the degreasing agent, then take out the aluminum profile;

[0021] 4) Washing: Rinse the aluminum profile taken out of the degreasing agent with clean water until the degreasing agent is completely washed away;

[0022] 5) Pickling: Then put the aluminum profile washed in step 4) into the pickling solution of hydrofluoric acid and nitric acid and soak for 3 minutes. While soaking, heat the pickling solution to 45°C and keep stirring;

[0023] 6) Surface adjustment: soak the ...

Abstract

The invention discloses an aluminum profile cleaning process. The aluminum profile cleaning process comprises the following steps that 1) degreasing is carried out, wherein an aluminum profile is putinto a degreasing agent bath solution with the temperature of 20-25 DEG C and is soaked for 3-5 minutes, the degreasing agent is stirred constantly, and then the aluminum profile is taken out; 2) washing is carried out, wherein the aluminum profile which is taken out from the degreasing agent is washed by using clean water until the degreasing agent is completely washed away; 3) pickling is carried out, wherein the aluminum profile washed in the step 2) is put into a pickling solution of hydrofluoric acid and nitric acid and is soaked for 2-4 minutes, and the pickling solution is heated to 40-55 DEG C while soaking is carried out and is stirred constantly; 4) surface adjustment is carried out, wherein the aluminum profile subjected to pickling is put into a colloidal titanium salt solutionfor soaking for 2-5 minutes, and the colloidal titanium salt solution is stirred constantly; 5) phosphating is carried out, wherein the aluminum profile subjected to the surface adjustment is put into a phosphating solution for soaking for 5-10 minutes, and temperature of the phosphating solution is set at 40-50 DEG C while soaking is carried out; and 6) passivating is carried out, wherein the phosphated aluminum profile is put into a passivation solution for passivation. The aluminum profile cleaning process has the advantages of being good in cleaning effect and the like.
