Summary of the invention
The object of the present invention is to provide a kind of copper alloy surface treatment process, have processing step few, environmentally friendly, qualified
Rate is high, the copper alloy band by processing being capable of high temperature resistant and the advantages that salt air corrosion.
Another object of the present invention is to provide a kind of equipment for running the copper alloy band process of surface treatment.
The present invention is achieved by the following technical solutions:
A kind of copper alloy band process of surface treatment, comprising the following steps:
A) unreel: copper alloy band unreels；
B) inhibition-Passivation Treatment: copper alloy band is immersed in inhibition-inactivating treatment liquid, inhibition-inactivating treatment liquid is to copper alloy
Strip surface carries out inhibition-passivation reaction；
Copper alloy band after inhibition-passivation reaction: being carried out ultrasonic oscillation rinsing processing by C) surface cleaning processing in water,
High-pressure spraying flushing is carried out with water again；
D) surface cure is handled: copper alloy band being immersed in passivation hot water of the temperature more than or equal to 75 DEG C and is carried out at surface cure
Reason；
E it) winds: winding copper alloy band after drying.
Band can form layer protecting film in alloy surface after inhibition-Passivation Treatment, before surface cure processing,
This layer of protective film is more fragile, needs to carry out it cleaning on surface.Surface cleaning processing process is to first pass through ultrasonic oscillation
Rinsing processing, rinses out remaining inhibition-passivating solution using high-pressure spraying.Copper alloy band after cleaning up is by surface
The copper alloy band that surface has protective film is obtained after curing process, drying, the protective film high temperature resistant on surface, salt spray resistance are rotten
Erosion.And during processing, every one-inch copper alloy band all have passed through inhibition-Passivation Treatment, therefore product qualification rate is high.
The step B) in, the reaction time that copper alloy immerses in inhibition-inactivating treatment liquid is 15-20 seconds, and inhibition-is blunt
Changing treatment fluid temperature is 50-60 DEG C；Temperature is too low, and reactivity is low to be caused to handle time increase even qualification rate decline, temperature
It is excessively high to will increase cost of equipment maintenance and increase power consumption.
The step B) in, it is 0.35-0.45 meter per second that inhibition-inactivating treatment liquid, which washes away copper alloy band superficial velocity,.
In chemical reaction groove, inhibition-inactivating treatment liquid is flowing, sufficiently washes away copper alloy band surface, more can sufficiently rush
The fine gap of brush copper alloy surface, and substitute the inhibition-inactivating treatment liquid on copper alloy band surface quickly, raising processing
Efficiency and qualification rate.Eroding velocity is excessively slow, it is necessary to and increase the reaction time of copper alloy band, reduces yield in unit time, and
And the impact force of water flow is not enough to wash away fine gap, and qualification rate is caused to decline；If eroding velocity is too fast, copper alloy is gentle
Erosion-inactivating treatment liquid interface bubble can excessively reduce reaction efficiency and prevent fine gap from adequately being washed away and
Reaction reduces qualification rate, and flow velocity is excessively high also to carry out excessive load to equipment belt, increase energy consumption and cost of equipment maintenance.
The step C) in, it is common that ultrasonic oscillation rinsing processing water used, high-pressure spraying, which rinse water used,
The tap water of filtering.The tap water commonly filtered is the water body for removing the large particulate matters such as suspended particulate, silt in water quality, filtering
Precision is 5 μm, and 5 μm of combination PP cotton filter device filtering tap water can be used.The present invention does not need the water using high-purity,
Reduce the energy and cost of equipment maintenance consumed during drainage, and thereby reduces production cost.
The step D) in, the passivation hot water is coarse filtration tap water of the conductivity less than 30 μ s/cm.Work as passivation
When hot water temperature is lower than 75 DEG C, the cover layer that copper alloy surface generates fails adequately to be solidified, during products storage
Copper alloy band surface layer can generate moisture absorption phenomenon, seriously affect the resting period of finished product, while can also generate slight high temperature oxygen
Change metachromatism；Meanwhile extracting during continuously generating and drying also is produced a very large impact, actual production efficiency is reduced,
Influence finished product output.When being passivated hot water temperature higher than 75 DEG C, have to extracting during continuously generating and drying effect very big
Benefit；Passivation hot water temperature 75 DEG C of -85 DEG C of sections meet film layer solidify and the factor of energy consumption outside, it is also desirable to consider produce
The actual maintenance cost of system: when being passivated hot water temperature greater than 85 DEG C, the aging phenomenon generation of equipment is seriously affected, and is shortened
The replacement cycle of equipment while affecting manufacturing schedule, also increases real cost of production.
