Pure water is used the pyrite tube core after described first time pickling to carry out pure water rinsing for the first time, to remove described first
The first acid solution on pyrite tube core after secondary pickling.
Described first time pure water rinsing is the pure water rinsing twice using water resistance rate to be at least 10M Ω cm.
Step 2, the second acid solution is used the pyrite tube core after described first time pickling to carry out second time pickling, so that institute
State the brass pipe wicking surface after pickling for the first time produce protecting film and go the removal of impurity, thus obtain the brass pipe after second time pickling
Core.
Described second acid solution includes the component of following parts by volume: mass fraction is phosphatase 11-1.5 parts, the mass fraction of 85%
It it is hydrogen peroxide 1-1.5 part and water 2-2.5 part of 35%；
Pickling for the second time is carried out in following process conditions: the time is 40s-60s.
Prior art cause brass pipe wicking surface coarse and the reaction of reason the second acid solution that pyrite die thickness reduces
Fierceness, reacts wayward, and pyrite tube core becomes relatively rough through this intense reaction later stage surface, and thickness also reduces 0.1mm-
0.3mm.So further resulting in pyrite tube core in follow-up upper glue process recessed in upper offset plate, rubber can not be wiped clean completely,
Brass pipe wicking surface cull fraction defective is 0.5%-1.0%.In polishing process, brass pipe wicking surface parcel white glue causes further
Making polishing difficulty increase, the usage amount of the dishcloth that polishing uses also increases.
And when using second acid solution of the present invention that pyrite tube core is carried out pickling, response speed can be controlled very well,
Brass pipe wicking surface after pickling is smooth, and the decrement of pyrite die thickness also decreases, and the rubber during gluing is also
More convenient, brass pipe wicking surface cull fraction defective is 0.1%-0.3%.Meanwhile, pickling time has reduced, when saving
Between, improve production efficiency simultaneously.

The second acid solution on pyrite tube core after secondary pickling.
Described second time pure water rinsing is the pure water rinsing twice using water resistance rate to be at least 10M Ω cm.
Step 3, employing the 3rd acid solution carry out third time pickling, with complexation institute to the pyrite tube core after described second time pickling
State the impurity of the brass pipe wicking surface after second time pickling and be allowed to be formed water soluble complex, thus after obtaining third time pickling
Pyrite tube core.
Described 3rd acid solution is mixed to get according to volume ratio 1-1.5:4-4.5 by ammonia and water.
Pure water is used the pyrite tube core after described third time pickling to carry out third time pure water rinsing, to remove the described 3rd
The 3rd acid solution on pyrite tube core after secondary pickling, can also make other organic impuritiess and pine that brass pipe wicking surface remains simultaneously
Fragrant removal.
Described third time pure water rinsing concrete operations are as follows: the water resistance rate first by room temperature is at least 10M Ω cm
Pure water rinsing once, re-use the water resistance rate that temperature is 60 DEG C-80 DEG C and be at least the pure water rinsing of 10M Ω cm once.
Wherein, the ammonia of brass pipe wicking surface can be rinsed out by pure water rinsing for the first time, and second time is rinsed can be further by pyrite
Ammonia remaining on tube core and complex wash.
Step 4, brass pipe wicking surface after described third time pickling plate layer of metal layer, to obtain the Huang after coating
Copper tube core.
The thickness of the described coat of metal is 3-10 μm.
Described metal level is the most oxidizable and the preferable metal level of solderability.Described metal level can use plating or chemistry
The method of plating is plated to brass pipe wicking surface.
Step 5, the pyrite tube core after described coating is carried out ultrasonic cleaning, to remove the pyrite tube core table after described coating
The impurity in face, thus obtain the pyrite tube core after ultrasonic cleaning.
Described ultrasonic cleaning is that the pure water using water resistance rate at least 10M Ω cm utilizes ultrasonic waves for cleaning three times, often
The time of secondary ultrasonic cleaning is 6min-15min.
Step 6, use drier carry out spin-drying to remove its surface to the pyrite tube core after described ultrasonic cleaning
Moisture, thus obtain the pyrite tube core after drying.
The described drying time is 60s-100s.Use drier can to save directly by the moisture removal on pyrite tube core
The time of follow-up baking.
Step 7, the pyrite tube core after described drying carries out toasting for the first time process to remove moisture removal further, thus obtain
Obtain the pyrite tube core after baking for the first time.The moisture removed on pyrite tube core can ensure that the electrical of pyrite tube core.
The baking of described first time is carried out in following process conditions: baking temperature is 100 DEG C-150 DEG C, and the time is 1h-
2h。
Step 8, the surrounding of pyrite tube core after described first time toasts carry out gluing process, to obtain the Huang after gluing
Copper tube core.Surrounding gluing at pyrite tube core can make brass pipe core be effectively protected.
Step 9, the pyrite tube core after described gluing is carried out second time toast the adhesive curing being processed so that its surface, from
And obtain the pyrite tube core after second time baking.
The baking of described second time is carried out in following process conditions: baking temperature is 100 DEG C-200 DEG C, and the time is 5h-
10h。
Step 10, described second time is toasted after pyrite tube core be processed by shot blasting, the final one-tenth obtaining pyrite tube core
Product.
Polishing is the oxide in order to remove brass pipe wicking surface, improves the weldability of pyrite tube core.
