Abstract
The invention discloses a mechanical zinc plating technique which comprises the following steps of: 1) preplating: removing oil and rust and washing; 2) copper plating for priming: plating a thin copper layer on the surface of a workpiece by adopting a chemical copper dipping method, and washing after plating is finished; 3) zinc plating and excessive precipitation: adding zinc powder and dedicated initiator into a roller, rolling for 3-6 minutes; 4) zinc plating and precipitation: adding zinc powder, dedicated initiator, impact media and water into the roller, and rolling for 25-45 minutes; 5) surface passivation: placing the workpiece in passivation solution to form a passivation film; 6) aftertreatment: spin-drying, drying, detecting and accepting. The impact media refers to glass microbeads with the diameter of less than 0.5mm; the passivation solution is chromic nitrate. By adopting the process technology, the energy loss is low, the zinc-plating coating is uniform in thickness, and has good corrosion resistance, wear resistance and stability.

Mechanical zinc-plating is coating for protection against corrosion a kind of and electro-galvanizing, hot dip zinc-iron, Dacroment processing various process, uses very extensive in industrial production.There are deficiencies such as the thickness evenness of energy consumption height, zinc coating is poor, perishable, not wear-resisting in traditional mechanical zinc-plating process.
Summary of the invention
At the deficiencies in the prior art, the invention provides that a kind of energy loss is low, the uniform mechanical zinc-plating process of galvanized layer thickness.
Technical scheme: a kind of mechanical zinc-plating process may further comprise the steps:
1) plating pre-treatment: oil removing, rust cleaning, washing;
2) copper facing bottoming: the method that adopts chemistry to soak copper makes workpiece surface plate the thinner copper layer of one deck, plate after washing;
3) zinc-plated deposition is excessive: zinc powder and special-purpose initiator are added in the cylinder, and rolling time is 3～6min;
4) zinc-plated deposition: zinc powder, special-purpose initiator, impact media, water are joined in the cylinder, and rolling time is 25～45min;
5) surface passivation: workpiece is put into passivating solution, form passive film;
6) aftertreatment: dry, dry, detect and check and accept.
As preferably, described impact media is glass microballon, and diameter is less than 0.5mm.
As preferably, described passivating solution is by chromium nitrate.
Beneficial effect: compared with prior art, Technology of the present invention, energy loss is low, and the thickness of zinc coating is even, has good anti-corrosion, wear resistance and stability.
