Description
Technical field
The present invention relates to a kind of compound sun of electrolysis copper-iron alloy being stained protection for the corrosion of corronil seawaterline
Pole material, and electrode assembly made of the material again, and thus apply made of electrode assembly and prevent in seawaterline
Rotten electrolysis unit.
Background technology
Ship seawaterline is since pipe diameter is small, and the attachmentes such as elbow, threeway, valve are more, and straight pipe is short, seawater velocity
Height, the reasons such as turbulence level is big, not only corrosion failure is serious, but also corrosion protection is extremely difficult.Additional power source protection does not have so far
It applies with succeeding, the protection of sacrificial anode is widely used.But when using anode loss protection, due to
Seawaterline pipe diameter is mostly smaller, therefore current shielding is serious, and anode spacing is very limited, in ship seawater pipe
Whole process protection is carried out in road, it is difficult quite big, need considerable anode, and sacrificial anode is on naval vessel seawaterline
Mounting condition and can useful load it is extremely limited, it is impossible to the sacrificial anode for loading sufficient amount carries out whole cathodic protection, therefore only
It can be for the seriously corrodeds pipeline section implementation focus cathodic protection scheme such as bend pipe, threeway, pump, valve import and export.Due to seawaterline
It is exposed in flowing and the briny environment containing sand, protecting current density needed for cathodic protection is higher, therefore sacrificial anode consumes
Soon, due to the limited volume of seawaterline, it is also contemplated that the influence to fluid resistance, anode cannot be made larger, therefore anode
Service life be very restricted, it is therefore necessary within a short period of time according to design requirement regularly replace anode.Seawaterline
Main Breakage Reasons are impingment corrosions, and impingment corrosion increases with the increase of seawater velocity.Each seawaterline material has one
A critical flow velocity value, impingment corrosion destruction will be extremely serious when seawater velocity is more than the value.For this purpose, as seawater pipeline material,
All there are one allow design current velocity value for regulation.Under higher seawater velocity, anode loss protection is used merely, is still relatively difficult to resolve
Certainly corrode leakage problem.
The corrosion failure problem that the naval vessel seawater pipe that the reasons such as impingment corrosion are brought is improved by flow velocity becomes prominent,
Sea marine organism pollution problem is also a major reason for causing sea pipeline to break down, and causes line clogging, serious reduction
The flow of seawater, cooling effect decline, cause to suspend when serious, all cause the serious reduction of naval vessel performance.In copper and copper
During the protection of alloy seawaterline, using ferrous ion in seawaterline surface filming, to improve the corrosion resistance of pipeline, very
Already it has been applied.Ferrous ion forms one layer of hydrated ferric oxide protective film in copper alloy surface, not only has resistance to flowing sea
The mechanical erosion of water acts on, and can obviously block the cathode and anode process of corrosion reaction, has notable effect to the usur of regions of turbulent flow
Fruit.Traditional method for applying ferrous sulfate film forming protection into pipe-line system there are certain use limitation, however ferrous iron from
Son has obvious effects on really in terms of the film forming protection of copper alloy seawaterline.By installing electrolysis in seawater pipe
Slot is electrolysed iron anode wherein, by the electrolyte injection sea water service system containing iron ion, obtains ferrous ion and replaces other iron
Ion source makes copper and its alloy surface form a film to improve its corrosion resistance.
Naval technology equips research institute and carried out the protection of FeSO4 film forming and zinc anode Combined Protection warship with Chinese Academy of Sciences ocean
The experiment of ship seawaterline, the results showed that in the case where 5.3m/s seawater velocity alternation of wetting and drying situations are corroded 2 months, joint
The anti-corrosion effect of guard method is best, improves 13% than independent FeSO4 film forming, is 1.6 times of zinc anode protection, is unprotect shape
6 times of state.About the anode loss protection of copper alloy seawaterline, most countries recommendation at present sacrifices sun using ferroalloy
Pole, rather than sacrificial zinc alloy anode.After seawaterline etching problem is resolved, the copper ion of marine growth can be killed greatly
The problem of reduction, sea marine organism pollution, is more prominent, thus while solving seawaterline leakage problem, also needs to solve marine growth
The problem of being stained.
For etching problem and sea marine organism pollution existing for copper and copper alloy seawaterline, solution is independent electricity at present
Xie Tie, copper anode realize the antifouling method of corrosion protection.Its principle is to generate ferrous ion using electrolysis copper and iron composite anode materials to pass through
Hydrolysis etc. forms Fe (OH) 2 colloid, is attached on copper alloy surface, the iron ion being dissolved down can also be in copper alloy table
Rich iron film is formed on face, to increase the protecting effect of iron sacrificial anode.The copper ion that electrolytic copper anode generates is attached to glue
On body film, achieve the purpose that antifouling.Cathode copper-aluminium (iron) anti-soil technology is earliest by Britain's Chesterfield city cathode and electricity
Solution engineer Co., Ltd succeeds in developing for the antifouling and anti-corrosion of silent service submarine sea water piping system.Its cardinal principle is
It will be loaded on the copper anode and aluminium (iron) anode application direct current in suction box or filter.Copper under from copper anode dissolution from
Son has toxicity, after being mixed with the refrigerated sea water for inhaling people, causes toxic environment, it is suppressed that life is inhabited and adhered to marine growth
It is long, and flocculation material is formed after aluminium anodes electrolysis, as the carrier of copper ion, it is adhered to seawater flowing slowly and is that marine growth is easy
In the place of attachment, such as valve, elbow, condenser position, play the role of anti-fouling paint.And as the sea water piping system of cathode,
In cathode protecting state, corrosion is avoided.Therefore this technology is also known as cathode copper-aluminium (iron) antifouling aseptic technic, this
Technology is generalized to the industries such as surface ship, ship for civil use, ocean platform from naval ship.
For etching problem and sea marine organism pollution existing for copper and copper alloy seawaterline, it is single to solve technical measures at present
Only cathode copper, iron anode realize the antifouling method of corrosion protection, but there are electrode material consumption is too fast, electrolytic anode material filming is anti-
The problems such as rotten anti-fouling effect is insufficient and installation space limits.
