There are many different steps in the processing of aluminum profiles
. Due to the needs of the operation, various isolation additives are used. In the subsequent processing process, the release agent or grease attached to the surface needs to be removed. However, due to the particularity of aluminum alloys, the use of general cleaning agents or improper handling will cause damage to the surface of aluminum alloys, and even corrode aluminum alloys. Therefore, there are many precautions to be aware of when cleaning aluminum alloys.
1. Selection of cleaning agent
In industrial production, a multi-component composite cleaning agent is generally selected. The composite cleaning agent made of strong alkali, weak alkali, polymeric inorganic salt, surface active agent, etc. can effectively exert its own cleaning characteristics, thereby significantly improving cleaning efficiency. .
2. Control of foam
In metal cleaning, foam is very important to the pretreatment process, and a certain amount of foam is beneficial to some pretreatment processes. However, the quality of industrial aluminum cleaning agent does not depend on the amount of foam, but when spraying in, it is required that the cleaning agent has a low foam, otherwise it is difficult to carry out mass production normally.
3. Pay attention to the quality of washing
In order to reduce the pollution degree, it is necessary to clean the cleaning liquid entrained in the workpiece to reduce the pollution degree to the next process. Generally, multi-stage washing is considered, and the pollution of the washing water in the latter stage should not exceed one tenth of the workpieces cleaned in the previous stage, which can also save water resources better.
4. Strict operation
Check the operating status of the equipment every day, and observe the process parameters at any time to avoid corrosion caused by the workpiece staying in the equipment for a long time.
