Description
Technical field
The present invention relates to one kind to emulsify hair blackening liquid, belongs to technical field of metal material surface treatment.
Background technology
Blackening refers to by method physically or chemically, and the black protective film of densification is formed in surface of workpiece
Layer, so as to strengthen the antirust ability of workpiece, while beautifies the outward appearance of workpiece.According to the difference of film forming mechanism, blackening can be with
It is divided into oxidizing blackening, room temperature blackening, phosphatization nigrescence and waste heat to black.
Oxidizing blackening is to form one layer of fine and close Fe in steel surface3O4Film layer, so as to reach the purpose of nigrescence.Normal temperature is sent out
Black general principle is that in acid condition, substrate surface occurs displacement reaction with the soluble copper salt in solution and produces metallic copper,
Reacted immediately with the other compositions in solution, generate the insoluble mantoquita of black and deposit to substrate surface, so as to reach
The purpose of nigrescence.Room temperature blackening is broadly divided into system containing selenium and without selenium system.Waste heat black be using workpiece heat treatment or its
Waste heat in his process, make iron and steel parts in the moment contacted with hair blackening liquid, one layer is formed on surface and is firmly combined with, is not easy
The black macromolecule resin film layer to come off.
After nigrescence workpiece surface formed one layer of black film, sometimes black film than it is more loose will not be close, so as to not reach very
Some antirust, anti-corrosive effects, thus for the workpiece after nigrescence, it is necessary to workpiece carry out rust prevention by applying liquid material oil processing again so that
Nigrescence workpiece reaches long-term requirement for anticorrosion.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of workpiece for emulsifying hair blackening liquid, being handled by the hair blackening liquid,
