Abstract
The present invention relates to an ultra-calcium alloy material, alloy is composed of 0.01 to 3% of Bi and respective 0.001 to 2% of NA, Se, Al and Sn, and the rest is Pb. The alloy material has the advantages of favorable mechanical properties, good corrosion resistance and high hydrogen evolution overpotential, wherein HB=142MPa, signab=49.9MPa. The positive erosion products of positive slab lattice made of the material are PbO2, and the forming time of pole plates can be shortened for 3 to 4 hours. In addition, the manufacturing technology of the alloy material is simple and practical. The indexes of a closed lead-acid accumulator formed by assembling the slab lattice made of the alloy material all reach the requirements of Japanese industrial standard.
Description
The present invention relates to field of alloy material, particularly a kind of ultra-calcium alloy material that is used for the fully closed maintenance-free lead accumulator anode plate grid.
In recent years, lead acid cell develops to the enclosed non-maintenance direction, so the alloy material of the key part-anode plate grid in the store battery has been carried out big quantity research.At present, the Pb-Ca-Sn-Al alloy that extensively adopts is made grid both at home and abroad, the assembling enclosed cell.Yet there are three major defects in this alloy, that is: the physical strength of alloy is lower, can not satisfy the requirement of large-scale store battery; Because the anode plate grid surface that makes of this alloy generates PbSO
4And cause the distortion of grid to expand, easily cause internal short-circuit of battery and because the PbSO that the anode plate grid surface generates
4And cause the early stage capacity of battery to descend.
Purpose of the present invention, being intended to propose a kind of application Na element further strengthens the Pb-Bi alloy, and use the ultra-calcium alloy material that is used for the fully closed maintenance-free lead accumulator anode plate grid that Se goes bad and handles material, to overcome weak point of the prior art.
Purpose of the present invention can realize by following proposal.
Ultra-calcium alloy material is by Pb, Bi and additive Na, and Se, Al and Sn form.Its alloying constituent (weight) is: 0.01-3%Bi, 0.001-2%Na, 0.001-2%Se, 0.001-2%Al, 0.001-2%Sn, surplus Pb.
Above-mentioned alloy 480-500 ℃ of down fusing, is stirred, water and cast from the mould that temperature is controlled at 140-160 ℃, promptly make grid.
The present invention also can make alloy earlier with Sn and Na, joins in the Pb-Bi-Al alloy for preparing again, thereby casts grid.
This alloy grid is after active substance coating, and ageing treatment 3 days, and changed into through 17-19 hour just can be used for assembling accumulator.
Alloy material of the present invention can make the Pb-Bi alloy further strengthen after having added Na, improves the mechanical property of alloy material.Adopt Se to the material processing of going bad, can improve the corrosion resistance of alloy.Adding Al and Sn can improve the flowability of alloy, improve the casting manufacturability of alloy.Simultaneously, Bi, Al, Sn can also change the condition of surface of alloy, improves the surface activation energy of alloy, makes PbO
