Description

Bly-antimon-legering for elektriske akkumulatorers plategittere. Lead-antimony alloy for plate grids of electric accumulators.

Det er fra britisk patent nr. 802.825 kjent en bly-antimon-legering for elektriske akkumulatorers plategittere med 5— 11 pst., fortrinnsvis 5—8 pst. antimon, som ved siden av antimon inneholder 0,075— 0,1 pst. arsen, 0,04—0,12 pst. kobber og resten bly. Denne legering har overfor de normale hårdblylegeringer en særlig høy korrosjonsbestandighet ved siden av en til-strekkelig hardhet og fasthet. Det kunne påvises at denne legering ved drift av elektriske akkumulatorer, særlig når de anvendes for fremstilling av de positive plater, føres til et vesentlig høyere utladningstall for akkumulatoren enn det som ble opp-nådd med de tidligere vanlige legeringer for plategitterne. From British patent no. 802,825, a lead-antimony alloy is known for the plate grids of electric accumulators with 5-11 per cent, preferably 5-8 per cent antimony, which, in addition to antimony, contains 0.075-0.1 per cent arsenic, 0 .04-0.12 per cent copper and the rest lead. Compared to the normal hard lead alloys, this alloy has a particularly high corrosion resistance in addition to sufficient hardness and firmness. It could be shown that this alloy when operating electric accumulators, especially when they are used for the production of the positive plates, leads to a significantly higher discharge number for the accumulator than was achieved with the previously common alloys for the plate grids.

Det finnes imidlertid visse anvendelsesområder hvor også et arseninnhold på There are, however, certain areas of application where there is also an arsenic content

over 0,075 pst. undertiden fører til dannelse av arsenvannstoff ved gassing av akkumulatoren. Det er kjent at arsenvannstoff er en usedvanlig giftig gass, som allerede i forholdsvis små mengder kan virke sunn-hetsskadelig, ja sogar dødelig. Vanligvis er luftvekselen i batterirommene eller i vanlige oppstillingssteder for batteriene så stor, at det aldri kan opptre en dødelig eller skadelig konsentrasjon. Men det finnes spesielle anvendelsesområder, f. eks. som undervannsbåt-akkumulatorer eller above 0.075 per cent sometimes leads to the formation of arsenic hydrogen when gassing the accumulator. It is known that hydrogen arsenic is an exceptionally toxic gas, which even in relatively small quantities can be harmful to health, even fatal. Usually, the air exchange in the battery rooms or in the usual installation locations for the batteries is so great that a lethal or harmful concentration can never occur. But there are special areas of application, e.g. such as submarine accumulators or

stasjonære batterier som stadig står på permanent oppladning, som telefonbatte-rier, som anbringes i særlig trange rom, og hvor det kunne være tenkelig med en akkumulasjon av skadelig arsenvannistoff-gass. stationary batteries which are constantly on permanent charge, such as telephone batteries, which are placed in particularly narrow spaces, and where it could be conceivable with an accumulation of harmful arsenic hydrogen gas.

Det kunne påvises at allerede tilset-ningen av 0,04—0,12 pst. kobber til binær hårdblylegering bringer en vesentlig øking av korrosjonsfastheten. Imidlertid opptrer denne effekt ikke alltid jevnt. På over-raskende måte kunne det fastslås at til-setningen av de minste arsenmengder i størrelsesordenen 0,01 til mere enn 0,075 pst. fortrinnsvis 0,03 pst., alltid sikret en stabiliserende effekt av kobbertilsetnin-gen, således at en tilsetning på over 0,075 pst. arsen ikke er ubetinget nødvendig. It could be shown that already the addition of 0.04-0.12 percent copper to binary hard lead alloy brings a significant increase in corrosion resistance. However, this effect does not always appear uniformly. Surprisingly, it could be determined that the addition of the smallest amounts of arsenic in the order of 0.01 to more than 0.075 per cent, preferably 0.03 per cent, always ensured a stabilizing effect of the copper addition, so that an addition of over 0.075 percent arsenic is not absolutely necessary.

Oppfinnelsen består altså i en arsen-holdig blyantimonlegering for elektriske akkumulatorers plategittere med 5—11 pst., fortrinnsvis 5—8 pst. antimon, 0,04— 0,12 pst. kobber og resten bly, eventuelt med de vanlige forurensninger, og legeringen er karakterisert ved at arseninn-holdet ligger mellom 0,01 og 0,075 pst. The invention therefore consists in an arsenic-containing lead-antimony alloy for electric accumulators' plate grids with 5-11 per cent, preferably 5-8 per cent antimony, 0.04-0.12 per cent copper and the rest lead, possibly with the usual impurities, and the alloy is characterized by the arsenic content being between 0.01 and 0.075 per cent.

Virkningen ifølge oppfinnelsen, som består i en høyere korrosjonsbestandighet av legeringen, opptrer også når legeringen inneholder de ellers vanlige forurensninger, f. eks. små mengder sølv, vismut osv. Legges det vekt på en ennu mer ytter-liggående korrosjonsfasthet for legeringen, så kan det til hårdblylegeringen foruten de små mengder arsen og kobber dessuten tillegeres 0,01—1 pst. sølv. Derved kan korrosjonsfastheten samlet økes ytterligere, således at de verdier som oppnås med de kjente legeringer overtreffes. The effect according to the invention, which consists in a higher corrosion resistance of the alloy, also occurs when the alloy contains the otherwise common impurities, e.g. small amounts of silver, bismuth, etc. If emphasis is placed on even more extreme corrosion resistance for the alloy, then 0.01-1 per cent silver can be added to the hard lead alloy in addition to the small amounts of arsenic and copper. Thereby, the overall corrosion resistance can be further increased, so that the values obtained with the known alloys are exceeded.

Alt etter anvendelsesformålet kan man ved tillegering av sølv forandre kobbertil-setningens størrelse. Derunder skulle det ved et meget høyt sølvinnhold, eksempelvis på 1 pst,, velges et særlig lavt kobberinn-hold, eksempelvis 0,03—0,05 pst., mens ved Depending on the purpose of use, the size of the copper addition can be changed by adding silver. Below that, with a very high silver content, for example 1 per cent, a particularly low copper content should be chosen, for example 0.03-0.05 per cent, while at

et lavere sølvinnhold, f. eks. på 0,01 pst., a lower silver content, e.g. of 0.01 per cent,

skal det anvendes en høyere kobberverdi, should a higher copper value be used,

som eksempelvis kunne være 0,09—0,12 pst. which could, for example, be 0.09-0.12 per cent.

En med hensyn til korrosjonsfasthet særlig One with regard to corrosion resistance in particular

gunstig legering fremkommer når man favorable alloy appears when one

tilsetter 0,05 pst. kobber og 0,2 pst. sølv. adds 0.05 percent copper and 0.2 percent silver.
