Description
Technical field
The present invention relates to a kind of zincincation, particularly relate to a kind of for the middle-size and small-size rod iron of electronic product such as motor drive shaft, snail
The zincincation of bar.
Background technology
Along with the fast development of electron trade, the application in electronic product of the small-sized rod iron gets more and more, such as CD, VCD, horse
Reaching axle etc. and often can use miniature rod iron, tradition is that its color and luster of treated rod iron is poor, and resistance to corrosion is poor, and frictional resistance
Greatly, service life is short, and the rod iron after plating zinc on surface processes, its surface color is preferable, and anti-wear performance is good, is resistant to corruption
Erosion.
Summary of the invention
It is an object of the invention to provide a kind of zincincation that zinc-plated quality is tight, brightness is high.
For achieving the above object, the technical scheme is that the zincincation of a kind of rod iron, described technique include as follows
Step: (1) surface processes, and rod iron surface is carried out calcination process, removes the organic impurities on its surface, carry out with clear water
Clean；(2) zinc-plated, the rod iron after step (1) processes is placed in aqueduct, zincincation is: bath temperature is 15-25 DEG C,
The zinc-plated time is 5-10min, and zinc-plated PH is 10-11, and electric current density is 10-11A/dm2；(3) clean, will process through step (2)
After rod iron use clear water be carried out；Wherein, bath composition includes sodium hydroxide 100-120g/L, zinc oxide 8-12g/L, three
Ethanolamine 20-30mL/L, brightener 5-6g/L, be dissolved in water each composition during preparation, adds zinc powder 1-2g/L, stirs 1-2 hour
Except impurity such as lead, add brightener and can try plating.
Preferably, described zinc-plated thickness is for 0.2-0.5um.
The beneficial effects of the present invention is: by optimizing zincincation and the formula of plating solution, the table of prepared rod iron
Face bright degree is high, and Corrosion Protection is good, abrasion-resistant, and resistance is little, can be as the main parts size of the small electronic products such as motor.
