Using the titanium electrolytic anode with fin structure any in any of the above embodiment.
Based on the above-mentioned technical proposal, the embodiment of the present invention at least can produce following technical effect:
Firstly, can farthest play titanium as the excellent of anode metal using the titanium electrolytic anode of fin structure
Gesture expands the contact area with electrolyte as much as possible, accelerates reaction speed, improves production efficiency；And using effective support
Scheme effectively prevent the overlap joint occurred between fin structure because misoperation or spacing are excessively close or short circuit punch-through, guarantees to set
Standby and personnel safety.
Secondly, support construction is made of polytetrafluoroethylene material, there is excellent self-lubricating and resistance to corrosion,
Middle self-lubrication can prevent the contact area disbonding of fin structure and support construction, to influence entire anode fin
The work of piece, resistance to corrosion therein can guarantee titanium electrolytic anode can long-term stable operation in the electrolytic solution, and begin
Base portion is assisted to guarantee the constant space between anode fin together eventually.
Third, anode fin surface are covered with passivation layer, which depends on through oxalic acid surface corrosion and iridium shackles, energy
It is enough effective against hydrogen ion/fluorine ion corrosion in electrolyte, increases effective operating time.
4th, junction progress in the form of external seal flange and the interior recessed circle of sealing of base portion and interconnecting piece
Sealing so that the junction of base portion and interconnecting piece forms smooth arc-shaped surface, can preferably with connected in oxygen generating plant
The corresponding inserting position in portion forms the face contact between arc surface, expands sealing effective area, and lift-off seal effect prevents from being electrolysed
Liquid leakage, improves the overall security of equipment.
Finally, fin and interconnecting piece in addition to grafting, also use the welding manner of interior contact weldering, external argon arc welding, no
But destruction of this pressure welding mode of contact weld to thin-slab structure is prevented, the deformation for causing thin-slab structure to be likely to occur, also
The local temperature for preventing argon arc welding excessively high improves the weld strength of anode fin and guarantor to the adverse effect of thin-slab structure
It is substantially smooth its plane is demonstrate,proved, especially welded connecting region is opposed flattened.
In the following, simply introducing the manufacture craft of Ni―Ti anode of the present invention:
One, sorting
1. sorting be processing technology the first step and important one.Selection phase is required according to customer drawings
The material of the trade mark, specification answered, and the quality of sorting will have a direct impact on the quality and use of anode；2. to be infused when sorting
Meaning, titanium net: cannot have fracture of wire, appearance of being completely cured, titanium plate: template will select more smooth plank well, while notice that surface cannot
Have peeling, layering, crackle, the defects of.Suitable material is selected to reduce loss.
Two, blanking
1. after determining material shape, quantity or quality needed for making some equipment or product, from entire or bulk material
In；2. removing the operating process of the material of certain shapes, quantity or quality；3. after choosing material again, being wanted according to drawing and client
It asks and makes certain shape, quantity.It crosses, get ready and mark, punch.Whether need to polish, wherein will be strictly according to drawing
It is required that going to operate.Reasonable plan processing technology, reduces loss；4. blanking will have precision.
Three, it welds
Some products just need to weld after blanking, punching, and the welding of titanium material mainly uses the side of argon arc welding
Method, only identical material can just weld together.Plate, pipe welding manner are first to be fixed using spot welding, weldering later is full,
And net can only be welded.
Four, sandblasting
1. being ejected into a kind for the treatment of process on Titanium base surface by compressed-air power by sand-blasting machine.Sand material injection
Impact grinding is carried out to matrix, the impurity on surface, variegated and oxide layer are disposed, while sand-blasting machine keeps Titanium base surface thick
Change, improve the effective contact area in titanium surface, enhances the adhesive force of coating and too surface；2. the main points of sandblasting, the point of injection,
Pitted skin uniformly will be unable to drain spray.
Five, pickling
1. the pickling solution of acid cleaning process is generally the mixture of a variety of acid, mainly there are sulfuric acid, nitric acid and hydrofluoric acid etc., this
The corrosivity of a little mixed acid is very strong, while having the temperature of very strong oxidisability, higher corrosive medium, this is to anti-corrosion material
Corrosion resisting property propose very high requirement.Oxalic acid is poured into boiling water according to certain ratio, by substrate put into saucepan into
Row is boiled, is steeped；The oxide skin turned blue on substrate when 2. oxalic acid not only can effectively remove annealing, while can be made again by corrosion
Substrate surface is rougher, eliminates surface impurity；3. to pay attention to the variation of Titanium base when pickling, often to prevent becoming titanium oxalate.
Six, it anneals
1. annealing is that metal is heated slowly to certain temperature, enough time is kept, then with the one of Reasonable Speed cooling
Kind metal heating processing technology；2. some materials itself are with bending or deformation, we can be by some in blanking
Method is simply corrected with tool, the next work of the influence for being allowed to inexcessive.But high by the part of welding
For temperature with after the air pressure of sandblasting, the deformation of titanium-based material will be apparent；3. annealing can be such that the plank (net) deformed restores
Formation state；4. plank (net) is placed on a very thick steel plate, it is desirable that be laid flat whole, alignment corner.One is put again together
The steel plate of sample is diagonally tightened up a screw on plank (net).Squeeze lower two steel plates adequately to intermediate plank (net)
Pressure.It is sent into the stove of temperature 500 or so later and carries out adding hot sizing, reached after a certain period of time, keep the temperature 2 hours.
Seven, match liquid
Configuration precious metal solution is removed according to customer requirement actual demand.It is all usually to map out the previous of brush layer with liquid
What it was prepared, because what the liquid prepared will could use after the system of drying in the air after a period of time.While drying in the air processed, need not
It stirs with stopping, prevents liquid precipitation.
Eight, it brushes, toast, oxidation
1. the noble metal liquid that will be prepared, with brush and brushing on matrix, dried into drying oven, make liquid
Body quickly in conjunction with matrix, be also prevented from liquid along matrix to it is dirty when left trace.After drying, into having reached one
The stove held for some time for determining temperature pulls out, and makes its natural cooling, oxidation.It is brushed again.It repeats: brushing, drying, adds
Heat heat preservation, cooling；2. when preceding 5 brushings, liquid can fill matrix surface with overbrushing.Few brush liquid is needed below, is made
Liquid is brushed more evenly, while can also cover the place of front brush flower, makes attractive coat.It requires to wear masks when brushing, ring
It is border, ventilation, dustless, particularly cannot water breakthrough.To guarantee the pure of liquid, the beauty of plate face.
Nine, it examines
It is not only production process real time monitoring, product quantity, specification etc. check again for again after production, pass through reinforcing life
After test, packaging delivery.
