Description
Technical field
The present invention relates to scaling powder, particularly a kind of scaling powder of lead-acid accumulator bus-bar.
Background technology
Polar plate of lead acid storage battery welding in recent years adopts manual mode substantially superseded, and provisions of the relevant regulations issued by the State accumulator plate and the necessary machine automatic cast welding that adopts of bus-bar welding.Cast welding mode is generally all: the pole plate group of the positive plate of having folded, dividing plate (glass fibre separator paper), negative plate, first plate ear is soaked in scaling powder, again this pole plate group is moved to the plumbous liquid cast welding with mould, plate ear inserts the plumbous liquid of 500 ℃ of left and right, make plumbous liquid plate plate ear surface melting, then plumbous liquid cooled and solidified, so just makes multi-disc plate ear link together.The object that the plate ear of pole plate soaks scaling powder is to help welding, and plate ear surface is fused into one with plumbous liquid.
But ubiquity problem is plate ear and plumbous liquid lack of fusion; After plumbous liquid cooling but, bubble is more; Plumbous liquid is haftplatte ear not; Scaling powder consumption too much on sticky and separator paper or pole plate lead plaster, causes not converting being to after charging.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of scaling powder of lead-acid accumulator bus-bar, solution be plate ear and plumbous liquid lack of fusion, plumbous liquid cooling but after bubble many, plumbous liquid is the problem of haftplatte ear not.
Technical scheme of the present invention is, by following percentage by weight: metaphosphoric acid 8-15%, phosphate 3～8%, ethanol 10-15%, carmine 1-5%, all the other are water, total amount 100% forms.
The present invention also can be by following percentage by weight: metaphosphoric acid 8-11%, and phosphate 3-6%, ethanol 10-13%, carmine 1-3%, all the other are water, total amount 100% forms.
The present invention also can be by following percentage by weight: metaphosphoric acid 12-15%, and phosphate 6-8%, ethanol 13-15%, carmine 4-5, all the other are water, total amount 100% forms.
The present invention also can be by following percentage by weight: metaphosphoric acid 10-13%, and phosphate 4-7%, ethanol 12-15%, carmine 2-4%, all the other are water, total amount 100% forms.
The present invention also can be by following percentage by weight: metaphosphoric acid 12-15%, and phosphate 3-6%, ethanol 12-14%, carmine 2-4%, all the other are water, total amount 100% forms.
The present invention also can be by following percentage by weight: metaphosphoric acid 8-11%, and phosphate 6-8%, ethanol 10-13%, carmine 2-4%, all the other are water, total amount 100% forms.
In said components:
Metaphosphoric acid: soluble in water and generate orthophosphoric acid, metaphosphoric acid belongs to strong acid, that the oxide layer on stereotype ear surface is fallen by sour corrosion, expose fresh metallic lead, and metallic lead surface is to have the pit shape being corroded, object is to remove surperficial lead oxide, impel rough surface, because plate ear surface does not have to be more easily welded together with the plumbous liquid of high-temperature after lead oxide, due to plate ear rough surface, after entering, plumbous immersion has sticky effect, so this metaphosphoric acid belongs to the effect of antioxidant and surface corrosion agent for lead.
Phosphate: because plumbous liquid is at high temperature more active, be unfavorable for sticking to stereotype surface, so add this phosphate, it is the effect that belongs to metal active inhibitor, after plumbous liquid activity is inhibited, just than being easier to and stereotype ear surface adhesion, plumbous liquid temp is delivered to plate ear surface fast, and the lead on plate ear surface is melted, and impels the plumbous liquid of plumbous liquid and plate ear surface melting to be integrated.
Ethanol: because alloy liquid cooled and solidified becomes solid, can shrink generation pore and cause pad internal resistance to be unfavorable for greatly energising, so the effect that this ethanol has gas diffusion that bubble is eliminated; And because ethanol at high temperature has the effect of burning, metal is contributed to heating effect, the position temperature of scaling powder can be assembled more, be beneficial to fusing, can avoid soaking scaling powder and too much can explode lead simultaneously, because ethanol runs into high-temperature liquid state meeting rapid evaporation, can not cause this globule to run into the fried plumbous phenomenon of the plumbous liquid of high temperature.
Carmine: because plate ear scaling powder when soaking scaling powder can swash, what have climbs on glass fibre separator (glass fibre separator can referred to as dividing plate), climb to again in the lead plaster of pole plate, have plenty of operative employee for welding effect better, just soaking too many scaling powder on plate ear, even be dipped on glass fibre separator paper and lead plaster on also no matter, own good welding of management only.Metaphosphoric acid reacts with lead plaster and generates lead phosphate in fact, after lead phosphate, operation acid dosing and charging can not convert positive plate brown lead oxide or the velvet-like lead of negative plate (positive plate brown lead oxide and the plumbous being of the velvet-like lead of negative plate are all called plumbous being) that we need to, so can cause battery to be scrapped.This carmine object is that scaling powder is become to red liquid, if scaling powder is drawn onto on glass fibre separator paper or lead plaster, all can become red, operative employee also knows that own scaling powder soaks too much like this, and inspector might as well check, be more conducive to control product quality, so this belongs to indicator.
Use the method for scaling powder cast-weld batteries:
The first step: soak scaling powder, positive and negative plate ear all inserts scaling powder, guarantees the highly large 3～4mm of immersion liquid;
Second step: cast welding, the positive and negative plate ear that soaked scaling powder inserts plumbous liquation, and insertion depth is 3～4mm, makes its plate ear surface and plumbous liquid fusion;
The 3rd step: the good bus-bar of cast welding, cooling after plate ear and the fusion of plumbous liquid, the lead metal of plumbous liquid cooled and solidified is called bus-bar, extracts together from cast welded mold, and cast welding finishes.
The present invention is the scaling powder of welding between lead and lead, principle is to adopt metal oxidation resistance agent, activity inhibitor, the scaling powder of defoamer and colored indicator preparation, scaling powder of the present invention is through repeated tests, in 300 lead-acid accumulator welding processes, all there is not plate ear and plumbous liquid lack of fusion phenomenon, after plumbous liquid cooling but without Bubble formation, plumbous liquid is haftplatte ear not, and efficiently solve scaling powder consumption too much on sticky and separator paper or pole plate lead plaster, cause not converting to after charging the problem of being, if first reacting with metaphosphoric acid, lead plaster generates lead phosphate, after battery acid adding, lead plaster just can not generate lead sulfate, so lead phosphate does not convert brown lead oxide to after charging, the lead plaster and the sulfuric acid reaction that are not brown lead oxide do not store electric weight.Adopt scaling powder cast-on lead liquid temp of the present invention can reduce by 10 ℃, lead skim reduces 10%, cast-weld batteries time decreased 5%.
The specific embodiment
Below the specific embodiment of the present invention is elaborated.
For above-mentioned effect, can in formula range, suitably adjust according to welding quality: plate ear and plumbous liquid welding are thorough not, metaphosphoric acid can be transferred to the upper limit (scheme 1), if plate ear surface is oxidized, adopt many these schemes of metaphosphoric acid to be beneficial to cast welding; Welding position has bubble ethanol can be transferred to the upper limit (scheme 2), if welding is easily exploded plumbous or produced pore, just adopts many these schemes of ethanol to be beneficial to cast welding; Plumbous liquid does not glue and phosphate can be adjusted to the upper limit (scheme 3) on plate ear, if the sticky plumbous liquid of plate ear adopts many these schemes of phosphate to improve; If inhaled on separator paper or pole plate, have scaling powder, famille rose can be transferred to the upper limit, be beneficial to and find and control (scheme 4), due to workman's misoperation lead plaster or separator paper easily sticky scaling powder just adopt carmine many these schemes.As shown in the table:
