Description
Vynález se týká způsobu výroby velkoplošných, tvarově složitých samonosných skořepin galvanoplastickou cestou.The present invention relates to a process for the production of large-area, complex shape self-supporting shells by a galvanoplastic process.
Kovové reliefy se doposud vyrábějí tím způsobem, že originál reliefu, zhotovený z nekovového materiálu, slouží ke zhotovení pískové formy, do které se odlévá kov. Tím se vytvoří kovový originál reliefu. Zhotovení pískových forem je časově velice náročné a nákladné. Odlitky reliefu je nezbytné čistit od zbytků písku kartáčem, popřípadě tryskáním, přičemž dochází často k poruše jemných tvarů. Poté se reliefy leští, patinují a podobně. Tím se ovšem do určité míry změní i hodnoty proti originálu.Metal reliefs have heretofore been produced in such a way that the original relief, made of non-metallic material, serves to produce a sand mold into which metal is cast. This creates a metallic original relief. Making sand molds is very time consuming and expensive. Relief castings must be cleaned of sand residues by brushing or blasting, often resulting in failure of fine shapes. Then the reliefs are polished, patinated and the like. However, this will also change the values against the original to some extent.
Uvedené nedostatky odstraňuje způsob výroby velkoplošných, tvarově složitých samonosných skořepin podle vynálezu. Způsob je vhodný zejména pro výrobu reliefů, znaků a podobně galvanoplastickou cestou. Podstata vynálezu spočívá v tom, že negativní kopie zhotovená z originálu z plastu, silikonového kaučuku nebo vosku se na své funkční části pokoví elektrolyticky střídavě vyloučenou vrstvou niklu ze sulfamátového elektrolytu s leskutvornou přísadou a mědi z kyselého mědícího elektrolytu s leskutvornou přísadou, přičemž vrstva kovu při jednotlivém vylučování činí 1 až 5 μτη. a vylučování každého kovu se opakuje nejméně pětkrát.The above-mentioned drawbacks are overcome by the process for the production of the large-area self-supporting shells according to the invention. The method is particularly suitable for producing reliefs, features and the like by electroplating. The principle of the invention consists in that a negative copy made of an original plastic, silicone rubber or wax is electroplated on its functional part by an electrolytically deposited alternating layer of nickel of a sulfamate electrolyte with a brightening additive and copper of an acidic copper electrolyte with a brightening additive. individual excretion is 1 to 5 μτη. and the deposition of each metal is repeated at least five times.
Takto vyloučená vrstva je velmi pevná a samonosná. Vlivem střídání tenkých kovových vrstev se snižuje podstatně koeficient roztažnosti na aritmetický průměr roztažnosti obou kovů, což umožňuje používat elektrolyticky vyloučené velkoplošné tvarově složité skořepiny v rozmezí od —15 až +30 °C. Způsob umožňuje zhotovování tvarově složitých velkoplošných samonosných povrchu originálu. V případě potřeby se samonosné skořepiny mohou po sejmutí na zadní straně vyplnit nekovovým materiálem, např. betonem, umělohmotnými pryskyřicemi s plnidly a podobně.The deposited layer is very strong and self-supporting. Due to the alternation of thin metal layers, the coefficient of expansion substantially decreases to the arithmetic mean of expansion of both metals, which makes it possible to use electrolytically excluded large-area complex shells in the range of -15 to +30 ° C. The method makes it possible to produce large surface-area self-supporting surfaces of the original. If desired, the self-supporting shells may be filled with a non-metallic material such as concrete, filler plastic resins and the like upon removal at the rear.
Příklad provedeníExemplary embodiment
Při zhotovování tvarově složitého velkoplošného reliefu byla z originálu odlita negativní kopie z lukoprenu.When making a large-area relief, a negative copy of lukoprene was cast from the original.
Tato kopie byla opatřena závěsným hákem, postříbřena chemickou cestou postřikem a po opláchnutí byla zavěšena do niklové lázně se sulfamátovým elektrolytem o složení:This copy was fitted with a hanging hook, silver plated by chemical spraying and after rinsing it was suspended in a nickel bath with sulfamate electrolyte of the following composition:
123 g/1 práškový uhličitan nikelnatý 200 g/1 kyselina aminosulfanová g/1 kyselina boritá 17 g/1 chlorid nikelnatý g 50 1 leskutvorné přísady — sacharln123 g / 1 powdered nickel carbonate 200 g / 1 aminosulfanoic acid g / 1 boric acid 17 g / 1 nickel chloride g 50 1 brighteners - saccharin
Teplota elektrolytu činila 40 °C při napětí 3 V a přoudavé hustotě 5 A/dm2. Po vyloučení niklovací lázně byl otisk opláchnut vodou a ponořen do kyselého mědícího elektrolytu o složení: 260 gramů síranu měďnatého na 1 1 vody, 60 g kyseliny sírové na 1 1 vody a 5 cm3 leskutvorné přísady. Teplota lázně činila 35 °C, proudová hustota 3 A/dm2. Po nánosu 5 μΐη měděné vrstvy a po oplachu vodou byl lukoprenový otisk zavěšen znovu do nlklovací lázně a poté do mědící lázně a to za stejných podmínek jako při vytváření prvních vrstev. Toto se opakovalo 5χ. Po posledním vyloučení kovu byla samonosná skořepina oddělena od lukoprenové negativní kopie a výrobek byl opláchnut a očištěn.The electrolyte temperature was 40 ° C at a voltage of 3 V and a current density of 5 A / dm 2 . After excluding the nickel plating bath, the imprint was rinsed with water and immersed in an acidic copper electrolyte of 260 grams of copper sulfate per liter of water, 60 g of sulfuric acid per liter of water, and 5 cm 3 of brightening agent. The bath temperature was 35 ° C, the current density was 3 A / dm 2. After the 5 μΐη copper layer had been deposited and the rinsed with water, the Lukoprene imprint was suspended again in the flocculation bath and then in the copper bath under the same conditions as when the first layers were formed. This was repeated 5χ. After the last deposition of the metal, the self-supporting shell was separated from the Lukopren negative copy and the product was rinsed and cleaned.
