Description
Technical field
The present invention relates to a kind of zincincations of powder metallurgy holder.
Background technology
Powder metallurgy holder itself can have many holes, pickling cannot be carried out also can not directly carry out it is zinc-plated, because of nothing
The iron rust that method carries out pickled surface can not remove, if directly zinc-plated can subsequently cause surface from mildewing.
Invention content
The purpose of the present invention is to overcome above-mentioned limitation, to provide one kind keep powder metallurgy holder zinc-plated and
Quality is guaranteed, and the zincincation for the powder metallurgy holder that can be produced in batches.
The purpose of the present invention is achieved through the following technical solutions：
A kind of zincincation of powder metallurgy holder, is as follows：
A, the infiltration of powder metallurgy holder is handled；
B, powder metallurgy rack surface blasting treatment removes surface iron rust, and the proportioning of blasting treatment sand is 0.3mm：0.1mm=
70%：30%, the purpose using 30% 0.1mm fine sands is by the iron rust removal in workpiece surface little groove, it is ensured that iron rust energy
It is completely removed；10~20 minutes time of blasting treatment；
C, powder metallurgy rack surface is zinc-plated, the specific steps are：Electroplating pool carry out it is zinc-plated, washing three times, first time light extraction, ultrasound
Wave cleaning, is dried at second of light extraction for the first time, and oven temperature setting is 75 °~100 °, dries 30 minutes, passivation, again water
Wash three times, pure water, second dry, oven temperature setting is 75 °~100 °, is dried 30 minutes；
D, it is verified by salt mist experiment zinc-plated whether effective.
Preferably, the specific steps are be put into product in pressure vacuum tank, vacuum pressure is wanted for the infiltration processing of step A
In 0.09mpa or more, then negative pressure sucking infiltration liquid, infiltration liquid will be higher by 50~80mm of product, continue to vacuumize 10~15 points
Then clock is slowly unloaded down toward normal pressure, is being impregnated 5 minutes；Then product taking-up is placed on dryer infiltration liquid drying is net；Again
Product is put into washing tank, the infiltration liquid of excess surface is cleaned up with clear water；Product is finally put into water cure pond
In, constant water temperature infiltrates after solidification in 90 DEG C ± 5 DEG C, 15~20 minutes hardening times and closes hole；
Preferably, in the powder metallurgy rack surface zincincation of step C, electroplating pool carries out zinc-plated temperature and controls 5
~35 DEG C, washing is the room temperature in rinsing bowl three times, and 20~30 seconds every time, first time light extraction was the room temperature in nitric acid and hydrochloric acid pond
15~25 seconds, ultrasonic cleaning was to be cleaned 20~40 seconds in supersonic wave cleaning machine room temperature, and second of light extraction is in nitric acid and hydrochloric acid
Room temperature 15~25 seconds in pond are passivated as 10~35 DEG C of temperature in passivation pool, are passivated 10~20 seconds, and it is washing three times to wash again
Room temperature in slot, 20~30 seconds every time, pure water was that room temperature cleans 20~30 seconds.
In conclusion the present invention has the following advantages：Allow that powder metallurgy holder is zinc-plated and quality is guaranteed, and
It can produce in batches, it is cost-effective.
