Eletroplate you understand knowledge a few

Manufacturer of storage rackSweet clew: The basic course that appearance deals with divides roughly for 3 phase: Deal with before, deal with among after mixing, deal with.
1.1 before deal with
The spare parts is in before dealing with, the level is existing differently burr and smeary, some is corroded badly, to among deal with bring very big hardship, increase extra resistance to chemistry or electrochemistry process, sometimes down to makes part part or whole appearance cannot obtain film or velar layer, still can pollute electrolyte, influence appearance deals with the quality of the layer. Include to divide corrode of oily, dip, burnish, polishing, roll light, blow arenaceous, part to safeguard, outfit hang, add auxiliary electrode to wait.
1.2 among deal with
It is to gift spare parts all sorts of main level that expect performance, it is the center that appearance deals with, appearance deals with the stand or fall of quality basically depends on of this one phase deal with.
1.3 hind deal with
Be pair of film layers and film is auxiliary deal with.
Eletroplate professional term---Eletroplate the course is basic term

Make a metal outside the action of passivation condition die.
2.15 passivation
It is normal to the metal makes outside below particular environment deliquescent echo encounters serious obstacle, be in compare wide electrode potential make a metal deliquescent inside limits resonant rate falls very small action.
2.16 hydrogen are fragile
As a result of dip corrode, remove oil or eletroplate the metal in waiting for a process or alloy absorb hydrogenous atom and the brittleness of occasion.
2.17PH value
The commonly used logarithmic of AH+ of pH indicator activity loses a value.
2.18 matrix data
Can pile up on its metal or the material that make velar layer.
2.19 auxiliary cathode
Be made by plating for put an end to on certain place because power line too the burr that center and appears and scorch wait for defect, the cathode of some kind of appearance is added additionally in this place nearby, in order to expends local electric current, this kind additional cathode assists cathode namely.
2.2 auxiliary positive pole
Besides the positive pole that needs to use normally in eletroplate, be made by plating for improvement an electric current on appearance is dispersed and apply complementary add positive pole.
2.21 electroanalysis
Make electric current is in through electrolyte solution zincous, cathode occasion oxidation recovers from an illness resonant process.
2.22 polarization
When electric current passes electrode, deviate of electrode potential fit is balanced the phenomenon of potential.
2.23 saponification are resonant
The hydrolyze that grease issues in basic requirement is resonant.
2.24 cathode polarization
When dc passes electrode, cathode potential deviate is balanced potential the phenomenon to negative directional shift.
2.25 chamfer voltage
When electroanalysising, electrobath is polar the total voltage between.
