Two, bearing is put in water and clean, liquid detergent residual liquid is washed；
Three, bearing is put in nitric acid and carry out pickling；The quality accounting of nitric acid is 3～6%, and pickling time is 30～45
Second；
Four, bearing is put in water it is carried out；
Five, bearing carries out brightization for the first time process；
Six, bearing is put in water and clean；
Seven, bearing is carried out second time brightization；
Eight, bearing is put in water and clean；
Nine, bearing is put into neutralizer；
Ten, bearing cleaning；
11, bearing is carried out antirust treatment.
The method of described bearing pickling, for the first time in brightization, selects the mixing of potassium permanganate, tertiary sodium phosphate and sodium hydroxide
Liquid, the quality accounting of potassium permanganate is 3～5%, and the quality accounting of tertiary sodium phosphate is 6～9%, and the quality accounting of sodium hydroxide is
3～5%；The brightization time is 10～20 seconds for the first time.
The method of described bearing pickling, for the second time in brightization, immerses hydrochloric acid by stannum dichloride, metallic tin and is configured to brightization
Mixed liquor, the quality accounting of hydrochloric acid is 10～15%, and the quality accounting of stannum dichloride is 0.2～0.5%, and the quality of metallic tin accounts for
Ratio is 0.05～0.13%；The time of brightization is 30～60 seconds for the second time.
The method of described bearing pickling, the 9th step, neutralizer selection sodium carbonate liquor, the mass concentration of sodium carbonate liquor is
4～6%；The neutralization time is 10～20 seconds.
The method of described bearing pickling, the 11st step, select the sodium nitrite mixed liquor with pudding sodium as antirust solution, Asia
The quality accounting of sodium nitrate is 5～8%, and the quality accounting of sodium carbonate is 0.5～1%；The antirust treatment time is 60 seconds.
The present invention can reach following beneficial effect: the inventive method is reasonable, easily operates, it is ensured that the quality of product, fall
Low production cost.
Detailed description of the invention
Below the detailed description of the invention of the present invention is described in detail.
