Abstract
The invention discloses a kind of mechanical zinc-plating process, comprising the following steps: 1) treatment before plating: oil removing, rust and washing；2) copper facing bottoming: washing after making workpiece surface plate the layers of copper of layer, plate using the method for chemistry leaching copper；3) zinc-plated deposition is excessive: zinc powder and dedicated initiator being added in roller, rolling time is 7~10min；4) zinc-plated deposition: zinc powder, dedicated initiator, impact media, water are added in roller, and rolling time is 50~55min；5) surface passivation: putting the workpiece in passivating solution, forms passivating film；6) post-process: drying, drying, detection are checked and accepted.The impact media is glass microballoon, and diameter is less than 0.5mm；The passivating solution is by chromic nitrate.Technology of the present invention, energy loss is low, and the thickness of zinc coat is uniform, has good corrosion resistance, wearability and stability.
Description
Technical field
The invention belongs to overlay coating technical fields, and in particular to a kind of mechanical zinc-plating process.
Background technique
Mechanical zinc-plating be it is a kind of with electrogalvanizing, the coating for protection against corrosion of hot dip zinc-iron, the dacroment process various process, it is raw in industry
It is very widely used in production.That there are energy consumptions is high for traditional mechanical zinc-plating process, the thickness uniformity of zinc coat is poor, perishable, no
The deficiencies of wear-resisting.
Summary of the invention
In view of the deficiencies of the prior art, low, the uniform mechanical plating of galvanized layer thickness that the present invention provides a kind of energy loss
Zinc technology.
A kind of technical solution: mechanical zinc-plating process, comprising the following steps:
1) treatment before plating: oil removing, rust and washing；
2) copper facing bottoming: washing after making workpiece surface plate the layers of copper of layer, plate using the method for chemistry leaching copper；
3) zinc-plated deposition is excessive: zinc powder and dedicated initiator being added in roller, rolling time is 7~10min；
4) zinc-plated deposition: zinc powder, dedicated initiator, impact media, water are added in roller, rolling time be 50~
55min；
5) surface passivation: putting the workpiece in passivating solution, forms passivating film；
6) post-process: drying, drying, detection are checked and accepted.
Preferably, the impact media is glass microballoon, diameter is less than 0.5mm.
Preferably, the passivating solution is by chromic nitrate.
The utility model has the advantages that compared with prior art, technology of the present invention, energy loss is low, the thickness of zinc coat
Degree uniformly, has good corrosion resistance, wearability and stability.
