Description
Technical field
The present invention relates to the anti-rust device that is used for mobile equipments such as automobile, refer more particularly to the anti-rust device that is used for mobile equipment such as automobile that adopts that the impressed current cathode protection method makes.
Background technology
The principle of metallic cathode protection proposed in 1824, but just began successfully to be applied in industry, agricultural and various fields in life up to about nineteen thirty.Successfully be applied in the iron and steel naval vessel over more than 100 year, at the bottom of the protective layer of high voltage iron tower, underground or unsettled pipeline, underground cable, iron and steel harbour, the chemical storage tank jar, the corrosion control of water cooler and many other metal structures etc.
Metallic corrosion is an oxidizing reaction.Various metals (for example in solution or wet environment) atoms metal under certain condition can become metal ion and discharge electronics, form a voltage difference like this between the electronics of metallic surface surplus and the dissolved ion.When increasing metallic transition becomes metal ion, voltage difference will be more and more big.The limit that various metals form this voltage difference is different, and a kind of limit voltage difference of this spontaneous generation of metal is called the electropotential of this metal, and the electropotential of various metals is the natural characteristicss of itself.Active its electropotential of metal is low more.
Under certain environment, when the potential difference of iron ion in electronic shell on the metallic iron and the solution did not reach the electropotential of iron, more metallic iron will continue to become metal ion and discharge electronics.Have only just to reach an equilibrium state when this potential difference reaches the electropotential of iron, if can keep this equilibrium state always, metallic iron just can not continue corrosion.The corrosive environment takes place in, because the existence of oxygenant, the continuous trapped electron generation of oxygenant reduction reaction, metallic iron is that the electropotential that reaches itself will constantly discharge electronics and becomes metal ion, metallic iron will constantly be corroded like this.
The ultimate principle of galvanic protection is exactly to make protected metal be in the current potential lower than its electropotential, and protected like this metal just can not discharge electronics, and metal just can not become metal ion, and metal just can not be corroded.
The method of galvanic protection can be divided into two big classes: the cathode protection method of sacrificial anode and the cathode protection method of impressed current.
In the cathode protection method of sacrificial anode; use connects with protected metallographic phase than the more active metal of protected metal and forms a galvanic cell (because the electropotential of various metals is different; different metals is in contact with one another and will forms potential difference when being connected; generated a battery, this battery is called galvanic cell).Active like this metal becomes ion with regard to continuous release electronics, the sacrificing protection of active metal protected metal can be not oxidized.
The impressed current cathode protection method is to utilize the impressed current that adds; make the relative corrosive environment of current potential of protected metal be lower than the electropotential of itself; the corrosive environment takes place in; the needed electronics of oxygenant generation oxidizing reaction is provided by the impressed current that adds; just can not discharge electronics is transformed into ion to protected like this metal, and protected metal has just been avoided being corroded.
At present; what application was comparatively successful on mobile equipments such as automobile is the anti-rust device that adopts the impressed current cathode protection method to make; when reality was used, the most frequently used electric current lead-in mode of this kind anti-rust device was condenser coupling lead-in mode and resistance lead-in mode.Be their concrete structure of example explanation and principle of work etc. below with the automobile.
Adopt the structure of the anti-rust device of condenser coupling lead-in mode to comprise: to be installed in the field generator on the automobile, include the pulsed electrical field generating unit in the field generator, on body of a motor car, also be fixedly connected with at least one metal sheet as anode electrode, anode electrode and body of a motor car mutually insulated, the pulsed electrical field output anode of the capacitance coupling type on anode electrode and the field generator is electrically connected mutually, and the output cathode of field generator is electrically connected mutually with body of a motor car; During work, the impressed current of the impulse form that field generator produces imports body of a motor car by anode electrode; The shortcoming of the automotive electronics Rustproofing apparatus of this structure is: as the reference electrical voltage point, the current potential of body of a motor car can't be determined, causes the corrosion protection function not ideal enough with the corrosive environment of outside.
Adopt the structure of the anti-rust device of resistance lead-in mode to comprise: to be installed in the field generator on the automobile, include the DC electric field generating unit in the field generator, on body of a motor car, also be fixedly connected with at least one Naked and be exposed on the external metal sheet in the environment as anode electrode, anode electrode and body of a motor car mutually insulated, anode electrode is electrically connected mutually with the DC electric field output anode of field generator, and the output cathode of field generator is electrically connected mutually with body of a motor car; During work, the impressed current of the direct current form that field generator produces imports body of a motor car by anode electrode by wet corrosion environment on every side; The shortcoming of the automotive electronics Rustproofing apparatus of this structure is: only just have rust inhibition near near the zone the anode electrode, and just do not have rust inhibition for other most of zone, the corrosion protection effect is very undesirable.
Summary of the invention
The technical problem of solution required for the present invention is: the anti-rust device that is used for mobile equipments such as automobile that will provide the splendid employing impressed current cathode protection method of a kind of rust-proof effect to make.
For addressing the above problem, the technical solution used in the present invention is: the described anti-rust device that is used for mobile equipments such as automobile, comprise: can be installed in the field generator on the mobile equipment, include pulsed electrical field generating unit and DC electric field generating unit in the field generator, be characterized in: the DC electric field output anode of field generator can be electrically connected with the tail shape anode electrode that keep in touch on ground after on the mobile equipment mutually with an insulating mounting, also be provided with the pulsed electrical field output anode of at least one capacitance coupling type on the field generator, also be provided with an output cathode on the field generator.
