Description

Najdluzszy czas trwania patentu do 6 grudnia 1944 r.Wedlug patentu Nr 11379 rozwalcowy- wanie cynku na blachy i tasmy odbywa sie w ten sposób, ze w celu zwiekszenia odpor¬ nosci materjalu walcowanego na -rozdzie¬ ranie i dzialanie chemiczne, nawalcowuje sie na rdzen z cynku powloke z jednej lub z obu stron z glinu.Wedlug niniejszego wynalazku glin sto¬ suje sie jako rdzen, a cynk jako obustron¬ ne powloki pokrywajace glin.Taki produkt walcowania, w którym glin stanowi rdzen, a warstwy cymku nato¬ miast powloki, mozna z korzyscia stoso¬ wac np. jako materjal do wyrobu elektrod cynkowych do elementów galwanicznych mokrych, do suchych baterji anodowych i t. d. Gdy powloka cynkowa takich plyt elektrodowych jest mocno nagryziona, a nawet calkowicie lub czesciowo zuzyta, to rdzen glinowy utrzymuje znajdujace sie na nim resztki cynku i zapobiega wskutek te¬ go spieciom i przedwczesnemu zniszczeniu elementu, az do zupelnego zuzycia cynku.Dalej pozadanem jest w wielu przypad¬ kach, aby wyglad cynku nie byl zmieniony przez powloki z glinu, któremu to warunko¬ wi mozna zadoscuczynic zapomoca niniej¬ szego wynalazku.Poniewaz przy wykonywaniu niniejsze¬ go sposobu nalezy brac pod uwage, ze cynkwyciaga fie p^^zcj wzglednie silniej pod cisnieniem walców niz glin, nie mozna wo- becrjtejo stasoWac obu skladników |akó tasm odwijajacych sie ze zwojów. Sposób wykonywa sie jak nastepuje.Na plyte cynkowa o odpowiedniej gru¬ bosci, która ogrzano do okolo 200 — 250°, naklada sie odpowiednia plyte glinowa, która moze byc wiecej ogrzana (az do 400°), poczem na te plyte naklada sie od¬ powiednio gruba i ogrzana plyte cynkowa.Plyta glinowa jest w kiefunktipodluznym nieco dluzsza, niz znajdujace sie z obu stron plyty cynkowe, poniewaz cynk przy walcowaniu wyciaga sie wiecej, niz glin. Ta wiazka z cynku i glinu zostaje nastepnie wprowadzona pomiedzy walce walcarki i polaczona pod odpowiedniem cisnieniem walców.Wiazka z dwu plyt cynkowych i srod¬ kowej plyty z glinu prowadzi sie na stole walcarki, pomiedzy bocznemi listwami, przyczem przyciska sie ja zapomoca spre¬ zynujacego walka, odpowiadajacego szero¬ kosci wiazki. Powstaje beznaganny, rów¬ nomiernie polaczony produkt. Rozwalco- wywanie takiej wiazki na blache lub tasmy bez konca, o dowolnej grubosci i szeroko¬ sci, mozna latwo wykonac, przyczem mate- rjal nie rozdziera sie na brzegach. PLThe longest term of the patent until December 6, 1944. According to the patent No. 11379, the rolling of zinc into sheets and strips is carried out in such a way that in order to increase the resistance of the rolled material to tearing and chemical action, the core is rolled of zinc, one or both sides of aluminum. According to the present invention, the aluminum is used as the core and the zinc as the two-sided coatings covering the aluminum. A rolling product in which the aluminum is the core and the cyanide layers are can advantageously be used, for example, as a material for the production of zinc electrodes for wet galvanic elements, for dry anode batteries, and so on. When the zinc coating of such electrode plates is badly bitten, or even completely or partially worn, the alumina core keeps on its surface. zinc residues and prevents premature fracture of the element until the zinc is completely consumed. Further, it is desirable in many cases to make the appearance of The resin was not affected by the aluminum coatings, a condition which may be satisfied by the present invention. For in carrying out the present method, it must be taken into account that zinc absorbs fie more relatively more under the pressure of the rollers than in the case of aluminum, you can use both components | as tapes unwinding from coils. The procedure is as follows: A zinc plate of appropriate thickness, which has been heated to about 200 - 250 °, is overlaid with a suitable alumina plate, which can be heated (up to 400 °), then the plate is then relatively thick and heated zinc plate. The aluminum plate is slightly longer in the longitudinal point than the zinc plates on both sides, because the zinc during rolling extends more than the clay. This bundle of zinc and aluminum is then introduced between the rolls of the rolling mill and connected under the appropriate pressure of the rolls. The bundle of two zinc plates and a center plate of aluminum is guided on the rolling table between the side bars, pressed together with the help of a spring loaded roller. , corresponding to the width of the bundle. A flawless, evenly blended product results. Rolling of such a bundle onto a sheet of metal or endless tapes, of any thickness and width, is easy to do, because the material does not tear at the edges. PL
