Abstract
A kind of cathodic protector being suitable for the dexterous type sacrificial anode applied in fresh water; comprise the web member as the spelter of sacrificial anode, the magnet of good conductivity and irony, described web member one end is embedded in the other end on described spelter and is embedded on described magnet and described spelter and described magnet is connected together.Cathodic protector structure of the present utility model is simple, easy for installation, does not have any destruction to claimed negative electrode, after installation, as the spelter difficult drop-off of sacrificial anode, and changes conveniently after corrosion.
Description
Technical field
The utility model relates to a kind of cathodic protector of sacrificial anode.
Background technology
There is corrosion reaction in carbon steel, cast iron etc., mainly oxygen uptake corrosion: H in fresh water
2o+1/2O
2+ 2e=2OH
-(cathodic reaction), Fe=Fe
2++ 2e(anodic reaction), the cathode protection measure of sacrificial anode can be adopted to suppress it to corrode.
Galvanic protection is using the negative electrode of protected metal as corrosion cell or electrolyzer, the electropotential of protected metal is negatively moved, dissolution rate reduces, thus prevent a kind of electro-chemical protection method of metallic corrosion.Galvanic protection is simple, and effective, is therefore applied widely.
When considering metal construction employing cathode protecting process, usually needing to consider that corrosive medium must have good electroconductibility, and enough amounts will be had continuous print circuit can be set up.Such as; be suitable in the media such as neutral salt solution, soil, seawater, river, alkaline solution, weakly acidic solution (as phosphoric acid), organic acid (as acetic acid) and carry out galvanic protection; and gas, air and other are non-conductive or electroconductibility is very poor medium (as the high purity water such as de-mineralized water and condensed water), then maybe can not should not apply galvanic protection.
According to the difference providing cathodic current approach, galvanic protection can be divided into galvanic protection and the impressed current cathodic protection two kinds of sacrificial anode.The galvanic protection of sacrificial anode is the metal that a connection current potential is comparatively born on protected metal; make protected metal become the negative electrode of the short circuit galvanic cell that it and sacrificial anode are formed, thus be dissolved as cost to prevent protected corrosion of metal with sacrificial anode.As inlayed the metallic zinc of sprinkling than ironwork at steel surface, make active metal oxidized, iron and steel is protected.
Like this, as the inlaying of zinc of sacrificial anode, be exactly a technical very strong job, do not do a good job and can gap and even destroy protected equipment inlaying place, zinc of long duration easily comes off, and also needs to be convenient for changing after zinc is corroded.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sacrificial anode difficult drop-off and changes the cathodic protector of dexterous type sacrificial anode easily.
Technical problem to be solved in the utility model is achieved through the following technical solutions: a kind of cathodic protector being suitable for the dexterous type sacrificial anode applied in fresh water; it is characterized in that; comprise the web member as the spelter of sacrificial anode, the magnet of good conductivity and irony, described web member one end is embedded in the other end on described spelter and is embedded on described magnet and described spelter and described magnet is connected together.
During use, directly by the magnet adsorption of cathodic protector of the present utility model on claimed negative electrode, namely complete the installation of the utility model cathodic protector, quick for installation, any destruction is not had to claimed negative electrode.
Described magnet is iron nickel cobalt magnet or ndfeb magnet.
Relative to prior art, the utility model has following beneficial effect:
Cathodic protector structure of the present utility model is simple, easy for installation, does not have any destruction to claimed negative electrode, after installation, as the spelter difficult drop-off of sacrificial anode, and changes conveniently after corrosion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cathodic protector of dexterous type sacrificial anode of the present utility model.
Embodiment
As shown in Figure 1, cathodic protector of the present utility model comprises the web member 3 as the spelter 1 of sacrificial anode, ndfeb magnet 2 and irony.Web member 3 is the joint pin of an arranged transversely, and its one end is embedded in the other end on spelter 1 and is embedded on magnet 2 and spelter 1 and magnet 2 is connected together.Cathodic protector of the present utility model is generally for the protection of iron and steel parts or equipment, and therefore web member adopts the material consistent with protected as better in iron and steel, iron effect.
The utility model cathodic protector structure is simple, dexterous, mounts and dismounts all very convenient, easy to use, practical.
be that the cathodic protector of the dexterous type sacrificial anode of the utility model is tested the protected effect of carbon steel in water below:
1) cathodic protector of dexterous type sacrificial anode zinc in tap water to the protected effect of carbon steel
experiment 1:(1) in 250mL Erlenmeyer flask, fill the tap water that 200mL connects from Engineering Department of Wuhan University nine teaching building water tap; (2) No. 20 carbon steel test pieces polished to light, measured size, clean up, be dried to constant weight, weighing; (3) cathodic protector of dexterous type sacrificial anode zinc is cleaned up be adsorbed on No. 20 carbon steel strip central authorities; then make No. 20 carbon steel test pieces vertically hang in the tap water of 250mL Erlenmeyer flask 24 hours, test piece to be submerged under liquid level at least 1cm but do not contact with at the bottom of bottle.
Test-results shows; in tap water; without No. 20 carbon steel test piece seriously corrodeds that the cathodic protector of dexterous type sacrificial anode zinc is protected; strip is attached with sorrel iron rust; shake Erlenmeyer flask iron rust comes off, and No. 20 carbon steel strip protected by the cathodic protector of dexterous type sacrificial anode zinc are smooth, corrosion-free.
Illustrate that the cathodic protector of dexterous type sacrificial anode zinc can prevent the corrosion of carbon steel in tap water, have good protected effect to the carbon steel as negative electrode.
) cathodic protector of dexterous type sacrificial anode zinc is at de-mineralized water and adjust protected effect to carbon steel in specific conductivity de-mineralized water
experiment 2:(1) in 250mL Erlenmeyer flask, fill the de-mineralized water that 200mL is prepared at Engineering Department of Wuhan University nine teaching building, and with analytical pure KCl, its specific conductivity is adjusted to 40 or 80us/cm; (2) No. 20 carbon steel test pieces polished to light, measured size, clean up, be dried to constant weight, weighing; (3) cleaned up by dexterous type sacrificial anode zinc cathodic protector and be adsorbed on No. 20 carbon steel strip central authorities, then vertically to fall in the desalination of the modulated specific conductivity of 250mL Erlenmeyer flask 24 hours, test piece to be submerged under liquid level at least 1cm but do not contact with at the bottom of bottle.
In the de-mineralized water heightening specific conductivity; No. 20 carbon steel strip of the cathodic protector protection of dexterous type sacrificial anode zinc are smooth, corrosion-free; illustrate that the cathodic protector of dexterous type sacrificial anode zinc can prevent the corrosion of No. 20 carbon steels in the de-mineralized water heightening specific conductivity, have good protected effect.
experiment 3: step is the same.
Test-results shows, and in de-mineralized water, no matter has, protects without the cathodic protector of dexterous type sacrificial anode zinc, and the corrosion of No. 20 carbon steel test pieces is all serious, and strip is attached with sorrel iron rust, and shake Erlenmeyer flask iron rust comes off.
To sum up, the cathodic protector of dexterous type sacrificial anode zinc is unsuitable for protecting iron and steel in the such pure water of similar de-mineralized water, and is suitable for protecting iron and steel in the de-mineralized water that improve at the larger tap water of specific conductivity or specific conductivity.
