Description
Technical field
The utility model is related to lead raw material quality detection technique fields, more particularly to a kind of lead test-strips casting mould
And lead test-strips.
Background technology
Lead accumulator has the history in more than 150 years so far, and application field is very extensive.In recent years, electric vehicle with its compared with
Good performance of riding instead of walk, lower storage space requirement and outstanding price advantage is grown rapidly in China, has benefited from this, accumulator
Industry has also obtained rapid development.
Lead accumulator is a kind of electrochmical power source, and chemical energy is changed into electric energy, belongs to reversible dc power supply, chemical close to the inner portion
Reaction storage electric energy or to power supply for electrical equipment.Lead accumulator is made of pole plate, partition board, electrolyte, battery case etc..Pole plate
It is the core of lead accumulator, the chemical reaction of accumulator charge and discharge mainly relies on active material and electrolysis on pole plate
Liquid carries out, and pole plate is divided into positive plate and negative plate, and positive plate and negative plate are all by grid and coated in the active material on grid
Composition.Grid and be lead coated in the active material main component on grid.
On the make, used lead powder is important semi-finished product to chloride plate, it is desirable that used raw material are
1# electrolytic leads Pb99.994.The Chinese invention patent of Publication No. CN102818789A discloses a kind of polar plate of lead acid storage battery use
Lead powder supplied materials grade determination method, dissolves lead powder using acetum, takes out residue lead group, absorbs water at once；
Under conditions of closed high temperature, residue is melted, obtains purer metal derby；The inspection of bi content is carried out to metal derby
It surveys, detection method is analyzed bi content using atomic emission spectrum or according to national standard.
A problem of the lead accumulator manufacturing enterprise through being commonly encountered is that the lead that buying comes is each by direct-reading spectrometer detection
The lead that component content all meets No.1 electrolytic lead standard is not sometimes No.1 electrolytic lead, is many times pyrogenic process lead bullion.Electricity
The production cost for solving lead is higher than pyrogenic process lead bullion, but the impurity content of two kinds of lead is very close to indistinguishable；And the usability of two kinds of lead
Diversity ratio is larger (final performance of slag yield and battery) on energy.、
Tensile strength is the maximum nominal tensile stress born before sample is broken, is metal from uniform plastic deformation to local collection
Maximum load-carrying capacity of the critical value and metal of middle plastic deformation transition under quiet stretching condition, for plastic material, its table
The drag of material maximum uniform plastic deformation is levied, for tensile sample before bearing maximum tension stress, deformation is uniform, but
Beyond later, metal starts necking occur, that is, generates and concentrate deformation.Fracture elongation refers to lead test-strips to being when fracture
The ratio of the length only extended and the length of lead test-strips itself before detection.
In drawing process, material enters after strain as lateral cross-sectional dimension is apparent sample after yielding stage
Reduce the stress obtained by the maximum, force (F) born when breaking divided by sample original cross-sectional area (S), referred to as tensile strength
(σ), unit N/mm2, it indicates that metal material resists the maximum capacity of destruction under a stretching force, and calculation formula is：σ=F/
S。
Utility model content
The utility model uses the lead in view of the deficienciess of the prior art, provide a kind of lead test-strips casting mould
Lead test-strips prepared by test-strips casting mould measure tensile strength and fracture elongation using universl tester, strong by tension
Degree and fracture elongation data can distinguish electrolytic lead and pyrogenic process lead bullion.
A kind of lead test-strips casting mould, including two pieces of templates being oppositely arranged, have in every piece of template and lead test-strips
The cavity that shape matches, the die top have the injection slot of the injection lead liquid in cavity, and two pieces of template sides are mutually cut with scissors
It connects, the other side is equipped with handle.
The mold bottom has the gas vent of connection cavity.
The template has multiple cavities being arranged side by side, and the injection slot is oblique along the side wall of cavity arragement direction
Face.
The utility model additionally provides lead test-strips made of a kind of utilization lead test-strips casting mould, including lead is surveyed
Strip ontology, the lead test-strips ontology both ends have the widened clamping part of width direction.
The length of the lead test-strips is 100-200mm.
The sectional area of the lead test-strips is 20-100mm2。
The utility model lead test-strips casting mould includes two pieces of templates being oppositely arranged, and two pieces of template sides are mutually cut with scissors
It connects, the other side is equipped with handle, and when use holds handle and abuts two pieces of templates, injects lead liquid into injection slot, lead liquid stream enters type
Be molded in chamber, it is cooling after after release handle takes out exemplar, trim cast gate and overlap and be made lead test-strips, it is easy to operate just
It is prompt.Lead test-strips are measured into tensile strength and fracture elongation using universl tester, pass through tensile strength and fracture elongation
Data can distinguish electrolytic lead and pyrogenic process lead bullion.
