Alkalihaltige Trübungsmittel für weiße Emaillen aus den für Trübungszwecke geeigneten Metallverbindungen mit Ausnahme jener des Zinns,Alkali-containing opacifiers for white enamels from those used for opacification purposes suitable metal compounds with the exception of those of tin,
Für die Herstellung weißer Emaillen sind bereits wasserhaltige und wasserfreie alkalihaltige Trübungsmittel aus den für Trübungszwecke geeigneten Metallverbindungen vorgeschlagen worden.For the production of white enamels, aqueous and anhydrous alkaline ones are already used Opacifiers proposed from the metal compounds suitable for opacification purposes been.
Es ist nun festgestellt worden, daß mit Ausnahme des durch Fällung aus Stannatlösungen erhältlichen Zinnoxydhydrats für die wasserhaltigen und technisch wasserfreien Trübungsmittel ein Alkaligehalt von 2 bis 7 Prozent, zweckmäßig ein solcher von 3 und 4 Prozent, die günstigsten Deckwirkungen hervorruft. It has now been found that, with the exception of that by precipitation from stannate solutions available tin oxide hydrate for the hydrous and technically anhydrous opacifiers an alkali content of 2 to 7 percent, expediently between 3 and 4 percent, produces the most favorable covering effects.
Für jede einzelne der für Trübungszwecke geeigneten Verbindungen kann der günstigste Alkaligehalt innerhalb der angegebenen Grenzen auf empirischem Wege leicht ermittelt werden.For each of the compounds suitable for opacification purposes, the most favorable Alkali content can easily be determined empirically within the specified limits.
