Examples
Embodiment 1
[0030] Recipe (by weight):
[0031] Detergent: MA-AA 2%
[0032] HEDP 6%
[0033] ATMP 8%
[0034] JFC 1‰
[0035] Water 84%
[0036] Corrosion inhibitor: 1‰ of the weight of CM-911 cleaning agent
[0037] preparation:
[0038] 1. First add the stated ratio of water into the cleaning agent preparation container, and then add the stated ratio of corrosion inhibitor (CM-911) and penetrant (JFC), and stir evenly.
[0039] 2. Add the proportion of MA-AA into the container in step 1 and stir evenly.
[0040] 3. Add the HEDP in the stated proportion, stir again, and finally add the ATMP in the stated proportion, stir well, and the obtained product A is a light yellow transparent liquid, odorless.
