Background technique
In electroplating industry, it is essential for implementation electroplating technology that each system, which always has some typical components,.
Including the electroplating bath for containing electroplating solution, it is known that the material compatible with conventional Electroplating Solutions have polypropylene, polyethylene,
PVC, PVDF, stainless steel, titanium, lead or glass etc..Electroplating bath size depends on electroplating bath and accommodates component to be electroplated and complete electricity
The ability of ancillary equipment needed for plating.
Ancillary equipment can ensure that plating solution performance is kept uniform and stable in electroplating process, to guarantee electroplating quality always such as
One.For keeping the heater and cooling device, the air stirrer and molten for ensuring homogeneous solution exchange of bath temperature
Alloy melt stirring device, the solution filtering device for removing hazardous particulate matter and the chemistry for keeping key chemical components concentration
Feeding system belongs to this column.
Another well-known key component of system is anode used in electroplating process.Plating must be by sun
Pole could form the complete circuit that production solution is flowed through for electronics, so that the metal of reduction in deposition process be made to appear in portion
On part, that is, so-called cathode.Electron stream follows effect electric field line and flows through electroplating solution, and electric field line is then by anode and cathode
Geometry or shape and anode and cathode present position determines relative to each other.
Quality of coating is heavily dependent on electric field line in the distribution situation of component or cathode surface.Ideally,
Should try to form uniform current distribution on entire cathode or parts surface, thus farthest improve quality of coating and
Uniformity.For there is the region of excessive electric field line, such as exterior angle and edge.High electron concentration may cause the electricity in these regions
It is high to plate rate, to cause the coating in these regions thicker.In some extreme cases, it is possible that porous no adhesion
Coating.On the contrary, seldom existing position, coating then may be relatively thin for the electric field lines such as components interior region, in some extreme feelings

When designing electroplating device, usually follows plating regulation and be designed for specific dimensions component.For example, in determination
When anode dimension, usually allow anode shorter than plating piece and about 2.5-10 centimetres narrow.Doing so helps to make electric current along plating piece
It is uniformly distributed on the region at edge, to reduce the variation of plating piece thickness of coating.
Once equipment purchasing is installed and put into production, rethink according to plating regulation more exchange device to meet other rulers
Very little plating piece production needs to become very difficult or even unrealistic, finishes because one side equipment has been assembled, in addition a side
The way of the other sizes anode suitable for different part dimensions is stopped work and installed from the perspective of cost and manufacture in face
And it is undesirable.
In addition, the more low-lying region of plating piece is low current density areas due to the complexity of plating piece shape, it is difficult plated with gold
Belong to coating, the especially cavity geometry of fuel tank one kind, inside in the plating process since current density is very low, be difficult comprehensive
Plate the coat of metal.
