Background technology
Polar plate of lead acid storage battery welding in recent years is substantially superseded using manual mode, and provisions of the relevant regulations issued by the State accumulator plate
Machine automatic cast welding must be adopted with bus-bar welding.Cast welding mode is typically all: the positive plate folded, dividing plate (glass fibers
Dimension separator paper), the pole plate group of negative plate, first plate ear is soaked in scaling powder, then this pole plate group is moved to the lead liquid with mould
Cast welding, plate ear inserts 500 DEG C about of lead liquid, makes lead liquid plate plate ear surface melting, then lead liquid cooled and solidified, thus makes
Many sheet ear links together.The purpose that the plate ear of pole plate soaks scaling powder is to help weld, and so that plate ear surface and lead liquid is melted for one
Body.
But generally existing problem is plate ear and lead liquid lack of fusion；After the cooling of lead liquid, bubble is more；Lead liquid not haftplatte ear；
Scaling powder consumption excessively glue with separator paper or pole plate lead plaster on, be not converted into being after leading to charge.
Content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of scaling powder of lead-acid storage battery busbar, solution be
Plate ear and lead liquid lack of fusion, after the cooling of lead liquid, bubble is many, the problem of lead liquid not haftplatte ear.
The technical scheme is that, by following percentage by weight: Metaphosphoric acid 8-15%, phosphate ester 3～8%, ethanol 10-
15%, carmine 1-5%, remaining is water, and total amount 100% forms.
The present invention also can be by following percentage by weight: Metaphosphoric acid 8-11%, phosphate ester 3-6%, ethanol 10-13%, carmine
1-3%, remaining is water, and total amount 100% forms.
The present invention also can be by following percentage by weight: Metaphosphoric acid 12-15%, phosphate ester 6-8%, ethanol 13-15%, kermes
Red 4-5, remaining is water, and total amount 100% forms.
The present invention also can be by following percentage by weight: Metaphosphoric acid 10-13%, phosphate ester 4-7%, ethanol 12-15%, kermes
Red 2-4%, remaining is water, and total amount 100% forms.
The present invention also can be by following percentage by weight: Metaphosphoric acid 12-15%, phosphate ester 3-6%, ethanol 12-14%, kermes
Red 2-4%, remaining is water, and total amount 100% forms.
The present invention also can be by following percentage by weight: Metaphosphoric acid 8-11%, phosphate ester 6-8%, ethanol 10-13%, carmine
2-4%, remaining is water, and total amount 100% forms.
In said components:
Metaphosphoric acid: soluble in water and generate orthophosphoric acid, Metaphosphoric acid belongs to strong acid, be make stereotype ear surface oxide layer sour
Property erode, expose fresh metallic lead, and Metallic lead surface be that have the pit shape being corroded it is therefore an objective to remove the oxygen on surface
Change lead, promote rough surface, because plate ear surface does not have after lead oxide to be easier to be welded together with the lead liquid of high-temperature, due to
Plate ear rough surface, lead immersion has viscous effect after entering, so this Metaphosphoric acid belongs to antioxidant and surface corrosion agent for lead
Effect.
Phosphate ester: because lead liquid is relatively more active at high temperature, be unfavorable for sticking to stereotype surface, so adding this phosphate ester
It is belonging to the effect of metal active inhibitor, after lead liquid activity is inhibited, be just easier and stereotype ear surface adhesion, lead liquid
Temperature is quickly delivered to plate ear surface, so that the lead on plate ear surface is melted, and promotes the lead liquid with the lead liquid of plate ear surface melting to be
Integrally.
Ethanol: because alloy liquid cooled and solidified becomes solid, generation pore can be shunk and cause pad internal resistance to be unfavorable for greatly
Energising, so this ethanol plays the role of gas diffusion eliminate bubble；And because ethanol has the effect pair of burning at high temperature
Metal contributes to heating effect, so that the spot temperature of scaling powder can be more assembled, and beneficial to fusing, can avoid soaking scaling powder simultaneously
Excessively lead can be exploded, because ethanol runs into high-temperature liquid state meeting rapid evaporation, be not result in that this globule runs into high-temperature lead liquid and explodes lead phenomenon.
Carmine: scaling powder can swash when soaking scaling powder due to plate ear, and have climbs to (glass on glass fibre separator
Glass hard board partition can be referred to as dividing plate), then climb in the lead plaster of pole plate, have plenty of operative employee for welding effect more preferably, just
Soaking too many scaling powder on plate ear, in addition be dipped on glass fibre separator paper and lead plaster on regardless of only managing oneself and good weld
Connect.Metaphosphoric acid and lead plaster react generation lead phosphate in fact, and after lead phosphate, operation acid dosing and charging will not be converted into us just needs
Plate Lead oxide brown or the velvet-like lead of negative plate (positive plate Lead oxide brown and negative plate velvet-like lead lead being are referred to as lead being), so can lead
Send a telegraph pond to scrap.This carmine purpose is that scaling powder is become red liquid, if scaling powder be drawn onto glass fibre separator paper or
All can become red on person's lead plaster, it is also known that oneself scaling powder soaks too much, coroner might as well check such operative employee, more conducively controls
Product quality processed, so this belongs to indicator.
Method using scaling powder cast-weld batteries:
The first step: leaching scaling powder, positive and negative plate ear all inserts scaling powder it is ensured that the highly big 3～4mm of immersion；
Second step: cast welding, the positive and negative plate ear insertion lead liquation of dipped scaling powder, insertion depth is 3～4mm so as to plate ear
Surface is fused with lead liquid；
3rd step: the good bus-bar of cast welding, cool down after plate ear and the fusion of lead liquid, the lead metal of lead liquid cooled and solidified referred to as confluxes
Row, extracts from cast welded mold, cast welding terminates together.
The present invention is the scaling powder of welding between lead and lead, and principle is using metal oxidation resistance agent, activity inhibitor, froth breaking
The scaling powder that agent and colored indicator are prepared, scaling powder of the present invention through repeated tests, 300 pieces of lead-acid accumulator welding processes
In, plate ear and lead liquid lack of fusion phenomenon all do not occur, after the cooling of lead liquid, bubble-free produces, lead liquid not haftplatte ear, and effectively
Solve scaling powder consumption excessively glue with separator paper or pole plate lead plaster on, be not converted into the problem of being after leading to charge, such as
Fruit lead plaster first reacts generation lead phosphate with Metaphosphoric acid, and after battery acid adding, lead plaster would not generate lead sulfate, so lead phosphate is filling
It is not converted into Lead oxide brown after electricity, be not that the lead plaster of Lead oxide brown does not store electricity with sulfuric acid reaction.Using scaling powder of the present invention
Cast-on lead liquid temp can reduce by 10 DEG C, and lead skim reduces 10%, and the cast-weld batteries time reduces 5%.
Specific embodiment
Hereinafter the specific embodiment of the present invention is elaborated.
For above-mentioned effect, suitably can be adjusted in formula range according to welding quality: plate ear is inadequate with lead liquid welding
Thoroughly, Metaphosphoric acid can be transferred to the upper limit (scheme 1), if plate ear surface is oxidized, be beneficial to using Metaphosphoric acid this schemes many
Cast welding；Welding position has bubble ethanol can be transferred to the upper limit (scheme 2), if welding is easily exploded lead or produced pore, just
Cast welding is beneficial to using ethanol this schemes many；Lead liquid is not viscous on plate ear can to adjust the upper limit (scheme 3) phosphate ester, if plate ear
Do not glue lead liquid, can be improved using phosphate ester this schemes many；If fluxing agent, kermes are inhaled on separator paper or pole plate
Red can be transferred to the upper limit, beneficial to finding and control (scheme 4), because the improper lead plaster of operative or separator paper easily glue and help
