2A12 aluminum plate in storage may be affected by the climate or storage environment of rust, that must be used when rust removal operation, sometimes can be pickled rust removal, then 2A12 aluminum plate manufacturers to introduce to you, 2A12 aluminum plate pickling effect factors.

1. Free acidity (FA)

Determining the free acidity of acid sink FA is a direct and effective evaluation method to verify the effect of acid sink rust removal.The acidity is too low, and the effect of rust removal is poor.When the free acidity is too high, the acid mist content in the working environment is too high, which is not conducive to protecting the surface of 2A12 aluminum plate.

2. Temperature and time

Pickling at room temperature, generally need to control the temperature between 40℃ ~ 70℃, temperature requirements will aggravate the corrosion of 2A12 aluminum plate workpiece, equipment, the impact on the working and living environment is also very adverse;The pickling time should be as short as possible to reduce the effects of corrosion and hydrogen embrittlement of 2A12 aluminum plates.The temperature of bath and the processing time of workpiece should be strictly controlled.

3, pollution aging

Acid in the process of rust removal work, will continue to develop into oil or some other impurities, which can be effectively removed by scraping suspended impurities;When the concentration of soluble iron more than we have technical content, the bath of rust removal can appear not only greatly improve the treatment effect is reduced, the excess iron ions accelerated phosphating bath ageing of environmental pollution, serious social of 2 a12 aluminum workpiece phosphating product quality, general acid iron ion content should be controlled in less than 6% ~ 10% advisable.

The above is the introduction of the factors affecting the effect of pickling rust removal of 2A12 aluminum plate. If you need to buy 2A12 aluminum plate or consult the price of 2A12 aluminum plate, you can contact us.
