Row cycle pickling is complete to cleaning.
Further: when carrying out pickling, firstly, the sample with rust is put into prepared acid in the environment of ultra sonic bath
In washing lotion, timing 1 minute；Secondly, take out sample after timing rapidly, respectively by tap water, deionized water and anhydrous
Ethyl alcohol cleaning；Finally, dry sample, makes to weigh in the balance.The above steps are repeated, cleans 10 times, is carried out according to obtained data
Zero-g aircraft.If the still visible corrosion product of specimen surface can suitably increase scavenging period after cleaning 10 times.Above-mentioned cleaning solution
In joined hexamethylenetetramine and adjust pH, and then improve the stability (H ion concentration stablize) when pickling solution cleaning；Meanwhile
The pickling solution for adding hexamethylenetetramine reduces the loss of substrate when cleaning, and can play corrosion inhibition to metallic substrates.In addition, making
Acid is hydrochloric acid, and the complexing power of chloride ion plays the role of inhibiting monovalence copper disproportionation, so that weightless result is more quasi-
Really.
Advantage for present invention:
