| Trouble
phenomenon |
Possible reason |
Correct method |
The low electric potential leaks
and is plated or location difference leaves |
a) bright pharmaceutical too much
b) The softener is insufficient |
a)Turn down the electrolytic consumption
to 3.0-3.5 of ph
b)Add the right amount softener |
The low electric potential hazes
whole degree dispersion |
a) bright pharmaceutical is insufficient
b)Resolve things organically more
c) Ph location is too high or too low |
a)Add the bright pharmaceutical properly
b)Deal with the active charcoal of hydrogen peroxide solution
c)adjusts properly to the craft range |
The low electric potential turns
black, send the dust |
a)Plate liquid have the impurity for copper,zinc etc
b) bright pharmaceutical too much |
a)Join right amount TPP to dispose of miscellaneous
pharmaceutical or low electric electrolytic
a)Turn down the electrolytic consumption to 3.0-3.5 of ph |
Plating layer has a needle of
holes |
a)Lack wetting-out agent,
b)The bodies of metal base have the defective or before deal with
bad
c) Boric acid the contents and temperature getting lower too
d)Organic impurity too much |
a) add the EHS wetting-out agents
b) Strengthen before deal with
c) Analyse the density of boric acid , heat the plate liquid
d) Deal with the active charcoal of hydrogen peroxide solution |
Plating layer has burrs coarsly
|
a) Plating liquid have suspending particle
b)Plating liquid is polluted by the mud and dreg of positive pole
c)Iron ion form hydrate and deposit on plating layer under the high
PH |
a)Filter in succession
b)Check positive pole bags of damage, plating liquid filter completely
c)Adjust PH to 5.5 to accede to QF powder, prevent iron work piece
from falling into the trough |
| plating layer grow into dim |
a)12 alkyl sulphuric acid sodium insufficient to dissolve
improper or one's own problematic quality
b)The boric acid is insufficient,PH index is too high
c)Resolve results more
d)Before deal with bad |
a)Check 12 alkyl sulphuric acid receive quality, If
it should be
dissolved correctly and supplements proper that quality is out of
question.
b)Supplement the boric acid and adjust PH index
c)Deal with the active charcoal of hydrogen peroxide solution
d)Strengthen before deal with |
| Grow dim after plating the chromium |
a)The saccharin measures too much in the Plating liquid
b)Time is too long for the putting amount after plating the nickel,
nickel layer purification |
a)Deal with electrolytic, stop adding the saccharin,
supply secondary bright pharmaceutical
b)Shorten lay time or liven up and deal with electrolytically with
10% of vitriol |
| Plating layer has stripes |
a)The zinc impurity is excessive in the plating liquid
b)Plating liquid density is too low
C)ph index is too low,DK is too big
d)The organic impurity polluting |
a)Join TPP removing miscellaneous pharmaceutical
b)Raise the content of nickel of sulphuric acid
c)adjust craft range
d) deal with to the ill |
| It is easy to burn to plate
layer |
a)Main salt density is too low
b)Plating liquide temperature is too low
c)the boric acid is insufficient,PH index is too high
d)The wetting-out agent is excessive
|
a)Supplementary after analysing compositions
b)Improve temperature to 55-60 degrees( Centigrade)
c)Supplement the boric acid and adjust PH index
d)Adopt the active charcoal to absorb |
| It is great fragility to plating
layer. |
a) bright pharmaceutical too much
b)The organic impurity polluting
c)The metal impurity is too high
d)six price polluting |
a)Turn down the electrolytic consumption to 3.0-3.5
of ph
b)Deal with the active charcoal of hydrogen peroxide solution
c)Join TPP removing miscellaneous pharmaceutical
d)Deal with the sodium hydrosulfite |
| The electric current of negative
pole is weak |
a)Main salt density insufficient
b)PH index is too low
c)Not enough area for positive pole sublimate positive pole
d) plate liquid is polluted by oxidant |
a)Improve main salt density
b)adjust craft range
c)raise the content of helium ion, Increase the area of positive pole
d) deal with to the ill |
