Incomplete neutralization and descaling of aluminum profiles may be caused by the following factors:
1. Process Parameter Issues: Such as insufficient treatment time, inappropriate temperature, or inaccurate solution concentration. If the treatment time is too short, the neutralization and descaling reaction may be insufficient; a temperature that is too low can slow down the chemical reaction rate; if the solution concentration does not meet the requirements, impurities cannot be effectively removed.
2. Improper Selection of Descaling Agent: Different aluminum profiles may require specific types of descaling agents. If the descaling agent does not match the aluminum profile, it is difficult to achieve the desired descaling effect.
3. Complex Surface Conditions of Aluminum Profiles: The aluminum surface may have severe oxidation, oil contamination, corrosion, etc., which increases the difficulty of descaling.
4. Issues with Pretreatment Processes: If previous steps such as degreasing or pickling are not handled thoroughly, residual contaminants will affect the effectiveness of neutralization and descaling.
5. Equipment Failures: For example, uneven stirring or malfunction of the heating device can cause the solution to fail in acting uniformly on the aluminum surface during treatment.
6. Aging of the Solution: During use, the descaling solution may age due to the accumulation of impurities or the depletion of active ingredients, thus reducing its cleaning capacity.
7. Water Quality Problems: If the water used to prepare the solution contains excessive impurities or has high hardness, it may affect the performance of the descaling agent.
To address the issue of incomplete neutralization and descaling of aluminum profiles, it is necessary to comprehensively consider the above factors, troubleshoot them one by one, and take corresponding improvement measures.
