Description

Multifunction electric coating bath
Technical field
The utility model relates to a kind of multifunction electric coating bath, belongs to electroplating technology field.
Background technology
Plating is exactly the process utilizing electrolysis principle to plate other metal or alloy of skim on some metallic surface, be utilize electrolytic action to make the technique of the surface attachment layer of metal film of metal or other material thus play to prevent burning (as corrosion), improve the effects such as wear resistance, electroconductibility, reflective, erosion resistance (copper sulfate etc.) and having improved aesthetic appearance.The skin of many coins is also plating.
During plating, coated metal or other insoluble materials do anode, and workpiece to be plated does negative electrode, and the positively charged ion of coated metal is reduced formation coating at workpiece surface to be plated.For getting rid of other cationic interference, and making coating evenly, firmly, electroplate liquid need be done, to keep the cationic concentration of coated metal constant with containing the cationic solution of coated metal.The object of plating plates metal plating on base material, changes substrate surface character or size.Plating can strengthen metal erosion resistance (the corrosion resistant metal of the many employings of coated metal), increase hardness, prevent abrasion, improve electroconductibility, slipperiness, thermotolerance and surface aesthetic.
Coating is single metal or alloy mostly, as titanium palladium, zinc, cadmium, gold or brass, bronze etc.; Also disperse layer is had, as nickel-silicon carbide, nickel-fluorographite etc.; Also has laminating layer, as the copper-nickel-layers of chrome on steel, the silver-indium layer etc. on steel.The body material of plating, except the cast iron of iron-based, steel and stainless steel, also has non-ferrous metal, or ABS plastic, polypropylene, polysulfones and phenoplast, but before plastic electroplating, has to pass through special activation and sensitized treatment.
Utilize electrolytic action on machinework, deposit the good but technology of the metal cover that performance is different with body material of attachment.Electrolytic coating is more even than hot dipping layer, generally all thinner, from several micron to tens microns not etc.By plating, decoration protectiveness and various functional upper layer can be obtained on machinework, the workpiece of wearing and tearing and processing error can also be repaired.
Plating is divided into rack plating, barrel plating, the continuously mode such as plating and brush plating, mainly relevant with batch with the size of unplated piece.Rack plating is applicable to the goods of stock size, as the collision bumper of automobile, and the handlebar etc. of bike.Barrel plating is applicable to smallclothes, as fastening piece, packing ring, pin etc.Continuous plating is applicable to mass-producted wire rod and band.Brush plating is applicable to local plating or repairs.Electroplate liquid has acidity that is acid, alkalescence and that be added with chelating agent and neutral solution, no matter adopts which kind of plating mode, the coating bath contacted, hangs tool etc. and should have versatility to a certain degree with goods to be plated with plating solution.
The low-voltage high-current power source that plating needs one are powered to plating tank and the electrolyzer be made up of electroplate liquid, part to be plated (negative electrode) and anode.Wherein to look coating different and different for electroplating bath components, but all containing the main salt providing metal ion, in the main salt of energy complexing, metal ion forms the complexing agent of complex compound, for the buffer reagent of stabilizing solution potential of hydrogen, anode activation agent and special additive (as brightening agent, grain-refining agent, leveling agent, wetting agent, stress relieving agent and inhibiting fog agent etc.).Electroplating process be the metal ion in plating solution under the effect of external electric field, be reduced into atoms metal through electrode reaction, and in the process of negative electrode enterprising row metal deposition.Therefore, this is a metal electrodeposition process comprising the steps such as mass transfer in liquid phase, electrochemical reaction and electrocrystallization.
In the coating bath filling electroplate liquid, through cleaning and the unplated piece of special pre-treatment as negative electrode, make anode with metal lining, the two poles of the earth connect with the negative pole of direct supply and positive pole respectively.Electroplate liquid is made up of the aqueous solution of the salt of the compound containing metal lining, conduction, buffer reagent, pH adjusting agent and additive etc.After energising, the metal ion in electroplate liquid, is moved on negative electrode in the effect of potential difference and forms coating.The metal of anode forms metal ion and enters electroplate liquid, to keep the concentration of the metal ion be plated.In some cases, as chromium plating, be the insoluble anode that employing is plumbous, lead antimony alloy is made, it only plays a part to transmit electronics, On current.Chromium ion concentration in electrolytic solution, need rely on and add chromium cpd to maintain termly in plating solution.During plating, the impurity, power supply wave shape etc. of the quality of anode material, the composition of electroplate liquid, temperature, current density, conduction time, stirring intensity, precipitation all can affect the quality of coating, need to control in good time.Electroplating principle comprises four aspects: the electrodeposition process of electroplate liquid, electroplating reaction, electrode and reaction principle, metal.
When people electroplate part, the most frequently used instrument is plating tank, and plating tank is most basic supporting in electroplating device.Plating tank is used for device solution, for zinc-plated, copper facing, nickel plating, gold-plated etc.Movable cathode plating tank serves as a contrast the cell body of soft polyvinyl chloride plastic, electric installation, steam heating tube and cathode moving device etc. by steel tank and forms.Cell body also can serve as a contrast Vybak manufacture with steelframe, and the factor such as character and temperature of bath solution is depended in the selection of trough body structure.But it is even that general plating bath plates article out there will be uneven coating, the problem that electroplating effect is bad.
