Description
Jest rzecza znana, iz zelazo lub cynk wzglednie zelazo pocynkowane, zanurzone w roztworach soli miedzi, np. siarczanu miedzi, pokrywa sie wskutek wymiany che¬ micznej warstwa miedzi, przy czym pewna ilosc zelaza lub cynku przechodzi do roz¬ tworu. Otrzymane powloki miedzi sa jed¬ nakze niejednolite i malo odporne zarówno mechanicznie, jak i chemicznie, wskutek czego nie chronia metalu podstawowego od nadzerania pod wplywem czynników atmo¬ sferycznych.It is known that iron or zinc or galvanized iron immersed in solutions of a copper salt, for example copper sulphate, is covered by chemical exchange with a layer of copper, with a certain amount of iron or zinc passing into the solution. The obtained copper coatings are, however, non-uniform and poorly resistant, both mechanically and chemically, and therefore do not protect the base metal from overshooting under the influence of atmospheric conditions.
W celu uzyskania jednolitych i trwalych powlok miedzi n& zelazie wzglednie zela¬ zie pocynkowajnym postepuje sie w ten spo¬ sób, iz blachy zelazne wzglednie zelazne blachy pocynkowane zanurza sie w roztwo¬ rze soli miedziowej, zadanym roztworem wodorotlenku zasadowego, np, wodorotlen¬ ku sodu, potasu, amonu, w obecnosci do¬ statecznej ilosci soli kwasu winowego, cy¬ trynowego lub innych kwasów organicz¬ nych o wiekszej czasteczce, posiadajacych zdolnosc zapobiegania wypadaniu wodoro¬ tlenku miedzi podczas alkalizowania roz¬ tworu soli miedziowej.In order to obtain homogeneous and durable coatings of copper and iron or zinc-coated iron, the procedure is to immerse the iron sheets or the iron zinc-coated sheets in a solution of copper salt with a preset solution of a basic hydroxide, e.g. sodium hydroxide. , potassium, ammonium, in the presence of a sufficient amount of salts of tartaric acid, citric acid, or other higher molecular weight organic acids having the ability to prevent the loss of copper hydroxide during the alkalization of the copper salt solution.
Wedlug wynalazku w celu zwiekszenia trwalosci i odpornosci powloki miedzi do roztworu dodaje sie soli glinu, chromu lub cynku. Wspomniany juz dodatek soli kwa¬ su winowego lub cytrynowego zapobiega równoczesnie takze wypadaniu z roztworu wodorotlenku glinu, chromu lub cynku podczas dodawania wodorotlenków.Z a s t f z % z e ti i c |itfefttowc.According to the invention, aluminum, chromium or zinc salts are added to the solution to increase the durability and resistance of the copper coating. The aforementioned addition of a salt of tartaric acid or citric acid also prevents the aluminum, chromium or zinc hydroxide from falling out of the solution during the addition of the hydroxides.
Sposób pokrywania zelaza oraz cyfckU, zwlaszcza blach zelaznych, cynkowych lub zelaznych pocynkowanyehf warstwa miedzi na drodze chemicznej przez zanurzanie to roztworze soli miedziowej zaprawianym dodatkiem wodorotlenków zasadowych, rtp. wodorotlenkiem sodu, potasu lub amonu, W obecnosci soli kwasów organicznych, np. kwasu cytrynowego lub winowego, zna¬ mienny tym, ze stosuje sie zasadowy roz¬ twór soli miedlziowej, db którego dodaje sie coli glirttt, chromu lub cynku.The method of coating iron and digital, especially iron, zinc or iron sheets, galvanized copper layer by chemical immersion by immersing it in a copper salt solution treated with the addition of alkaline hydroxides, etc. sodium, potassium or ammonium hydroxide. In the presence of salts of organic acids, for example citric or tartaric acid, characterized by the use of an alkaline copper salt solution to which coli glirttt, chromium or zinc are added.
