Description
Technical field
The present invention relates to red lead production facility fields, and in particular to a kind of work preparing rare earth red lead using regeneration lead plaster
Skill.
Background technology
Red lead product is mainly used in the fields such as lead-acid accumulator, medicine, paint pigment, electronics at present, but red lead produces
98% use above of product in lead-acid accumulator, red lead product deleted as battery positive plate in lead-acid accumulator in active matter
Matter, under normal circumstances, red lead with provide following reaction equation in cream and be changed into：
β-PbO2：Pb304+H2SO4→ β-Pb02+2PbSO4+2H2O
PbO2And Pb304Relationship by following formula state (wt%)：Pb304%=2.8662 × PbO2%
It is applied in lead-acid accumulator using the characteristics of red lead high oxidation amount, having improves solidification, shorten the chemical conversion time, carry
High deep-circulating performance improves the functions such as battery capacity and service life：
1. easily controllable solidification
Solidification is the key that one of battery pole plates quality.Plate buckling, shedding, service life are all related with solidification.Produce defect
Immediate cause be remaining free lead in lead powder (cream) quantity it is more.So cured main purpose is remaining lead in lead plaster
(free lead) is reduced to 5% minimum below.
Solidification temperature is related with green plate quality, and the green plate newly painted contains metallic lead, exothermic oxidation when solidification, so
Even if curing room temperature control at 40~60 DEG C, this will be far above inside pole plate.Thus real solidification temperature is difficult to grasp.
The remaining free lead of red lead is less than 2%, with red lead cream, is whether applied alone (i.e. with the red lead of content 25%) or mixes, and trip
It is eliminated from the relevant extra heat of lead, therefore is easier to grasp solidification.And due to that need not consider to aoxidize, three for controlling temperature and then generating
Alkali formula and rare earth red lead (crystalline size and shape) are easily managed, and total hardening time can shorten, the effect for reaching saving, rising matter
Fruit.
2. formation efficiency is higher
PbO in red lead2Account for about Pb3041/3, when positive plate is melted into will become subsequently generate PbO2Nucleus, make whole
A active matter effectively changes, therefore can promote chemical conversion, and the chemical conversion time is made to shorten, and chemical conversion power consumption reduces, and so-called " flower piece " waste product
Rate also declines.Tubular positive plate chemical conversion is more difficult, is often filled with the electricity of 10 times of capacity, and centre is subject to electric discharge 1~2 time, difficult
Make the PbO of finished product2More than 80%, 25% red lead is added such as in lead powder, then is easy to make PbO in finished product2More than 80%；Apply cream
Formula pole plate, if be melted into using battery case, especially with AGM, electrolyte flow is restricted, and is suitable for lead plaster to add red lead with profit especially
Chemical conversion.Therefore the use of red lead can save the time in formation process and improve pole plate electric energy technique.
3. accumulator initial capacity is higher
Battery (positive plate) discharge capacity is derived from PbO2, PbO2There are mainly two types of crystal forms, and one is α-PbO2, one is cried
β-PbO2.Their chemical composition is identical, mainly there is 2 points of differences：1. the crystallization of β types is tiny, size is approximately equal to the crystallization of α types
Half, therefore real table area of the β types crystallization with bigger；2. β types are tetragonal, α types are orthorhombic forms, β types and electric discharge
Product PbSO4Lattice parameter difference it is larger, PbSO4It cannot be along β-PbO2Lattice growth, and try hard to be formed the crystal grain of oneself,
Since crystal lacks, coarse PbSO is then formed4Crystallization, has between coarse grain compared with big gap, H2S04It readily penetrates through
PbSO4Layer, reaches active matter depths, pole plate depths active matter is enable to continue to discharge, so activity is higher, utilization rate is big, can give
Go out more capacitance.To the PhO2 of identical quantity, discharge under identical current density, the capacitance that β types provide be more than α types to
1.5~3 times of the capacitance gone out.
After anode diachylon uses red lead, it is melted into the β-PbO of generation2It is more, so its use can improve initial capacity,
Especially to fixed and industrial battery, international advanced lead-acid battery alliance (ALABC) has had proven to red lead for 2001 to VRIA electricity
Tankage generates advantageous effect.
4. improving the cycle life of fixed battery
Present red lead production technology can be adjusted suitably to keep PbO in red lead2Content is higher, there is higher β-in lead powder
PbO2Content can generate a large amount of rare earth red lead crystal, be conducive to the raising of battery cycle life after hardening.
It is described above function and significance of the red lead product in lead-acid accumulator.The service life of lead-acid accumulator at present
It it is exactly the time in 1 year and a half or so, with the development of electric vehicle, New-energy electric vehicle, the market capacity of lead-acid accumulator is got over
Come bigger, requirement of the people to the cruising ability of accumulator is higher and higher.In this way to the demand of the application study of novel storage battery
It is more and more urgent.How the cruising ability of accumulator is improved, it is important to how to improve the charge storage ability of accumulator.If using dilute
Reddle pellet product upgrades to red lead product, this target may be implemented.Because rare earth element is all very active gold
Belong to element, the rare earth red lead of preparation is easily formed stable rare earth red lead crystal seed applied to accumulator, and then improves lead acid storage battery
The capacitance in pond.
Invention content
Technical problem to be solved by the invention is to provide a kind of technical process is controllable, the high lead-acid accumulator of product quality
With the preparation method of rare earth red lead.
A kind of technique preparing rare earth red lead using regeneration lead plaster, steps are as follows：
