Description
Technical field
The present invention relates to a kind of magnesium alloy composite sacrificial anode material and preparation method thereof, be used for the corrosionproof protection of underground oil and gas pipeline, storage tank and various water pipe facilities.
Background technology
When carrying out cathodic Protection Design, protective current density is unusual important parameters, and different times underground oil and gas pipeline, storage tank and the required protective current density of various water pipe facility differ greatly.In general, underground oil and gas pipeline, storage tank and various water pipe facility corrosionproof protection initial stage, the initial stage that promptly polarizes, required protective current density is bigger, and after the initial stage, the needed protective current density of corrosion prevention will reduce greatly.Initial stage required protective current density design load is generally the twice of average protective current density design load in underground oil and gas pipeline, storage tank and the design of various water pipe facility antiseptic project.Though the polarization initial stage is very short with respect to the work-ing life of whole pipe during this period of time, but it is very significant for the work-ing life of pipeline and the influence of preservative effect, therefore, must pay much attention to this problem in the actual pipeline corrosion protection engineering design, just can guarantee protection effect, guarantee the normal use of pipeline configuration.
For guaranteeing to provide enough big protective current at the corrosion initial stage; must rely on increase anode quantity to remedy; and after the polarization stage at initial stage; required protective current density reduces greatly, at this situation by the planner propose that series resistance reaches the adjusting initial stage polarization purpose of protective current density afterwards in the loop that sacrificial anode and protected pipeline are formed.The drawback of doing like this be a large amount of sacrificial anode materials polarization just after date do not bring into play provide protection, but the resistance consumption of being contacted has fallen.
The composite sacrificial anode of being made up of two or more different sacrificial anode material is a kind of new technology that development in recent years is got up, and compares with traditional sacrificial anode material, has remarkable advantages in solving pipeline cathode protection.At present, its skin of the composite sacrificial anode that uses in the ocean environment is magnesium alloy, and it is bigger to drive current potential, can provide bigger protective current to make the iron structure rapid polarization at the polarization initial stage, reaches guard mode.After treating that outer magnesium anode all dissolves consumption, drive the lower but unlined aluminium alloy anode that current efficiency is high of current potential and start working, make protective current density adjust to lower level, thereby keep long-term, the stable polarization of steel construction, realize the purpose of corrosionproof protection.Through the test of laboratory simulationt test and the actual installation on platform, confirm that this composite sacrificial anode has that protection is effective, long service life and save advantage such as anode material significantly.
Yet the magnalium composite anode is directly used in the anticorrosion certain difficulty that but exists of underground oil and gas pipeline, storage tank and various water pipe facility, mainly is owing to generating oxide film easily at the aluminum in soil environment anode surface protective current sharply to be descended.Domestic and international research person attempts to reduce its polarization tendency by the method for alloying, yet polarized action still hinders the principal contradiction of its practical application in edatope.Fill out the method for construction materials contract by employing and can significantly improve this problem, but obviously increased the complexity and the maintenance cost of constructing.
Summary of the invention:
The object of the present invention is to provide a kind of magnesium alloy composite sacrificial anode material and preparation method thereof; it is a kind of double-layer magnesium alloy composite sacrificial anode material; its microstructure and precipitated phase by adding rare earth and controlling sacrificial magnesium alloy anode; formation has the magnesium-alloy anode material of two kinds of different corrosive propertys; form the magnesium alloy composite anode by composite casting method, for the underground oil and gas pipeline in the edatope, storage tank and the anticorrosion enforcement of various water pipe facilities are effectively protected.
Technical scheme of the present invention is such realization: a kind of magnesium alloy composite sacrificial anode material is characterized in that: magnesium alloy composite sacrificial anode material is made up of the inner layer material and the cladding material of high current efficiency.
The chemical ingredients of described magnesium alloy composite sacrificial anode material high current efficiency inner layer material is counted by mass percent wt%: Al:1.5-2.0, Mn0.5-2.0, RE0.1-2.0, Si≤0.050, Cu≤0.020, Ni≤0.001, Fe≤0.040, surplus are Mg; There is Al in the AlMnRE phase particle of tissue signature for distributing tiny in the inner disperse of the crystal grain of Mg on the grain boundary
