Ob im Garten, beim Maler oder auf der Baustelle: Leitern sind ein wichtiger Bestandteil vieler Gewerke. Besonders beliebt sind hier seit vielen Jahren Aluminiumleitern. Aluminiumleitern sollten robust, leicht zu transportieren, qualitativ hochwertig und vor allem sicher sein. Je nachdem, ob es um Anforderungen für eine einfache Stehleiter oder um professionelle ...
Electrolytical colouring with tin salts has been a popular process in anodising operations for decades. It can be used to produce numerous variants of bronze colourations (light to dark bronze), but also black surfaces on the aluminum base metal. While bronze shades were mostly predominant in recent decades, the process ...
Neben der täglichen Eigenüberwachung in Pulverbeschichtungsbetrieben fordern verschiedene Qualitätsgemeinschaften auch regelmäßige Korrosionstests beim Chemiehersteller oder in Instituten. Prüfungen sind wichtig, um die gleichbleibende Oberflächenqualität kontrollieren und garantieren zu können. Um der Vielzahl der zu testenden Prüfkörper bei Alufinish gerecht zu werden, musste hierfür in den letzten Jahren die Kapazität der ...
Small, white and unwipeable spots, visible on anodised and electrolytically coloured goods (e.g. C35 - Black), attract the observer's attention immediately and result in unsaleable goods and rework. This makes it even more important to quickly localize and eliminate the cause of the problem. Defect pattern: small, white dots on ...
Aluminium is a versatile resource. We have often reported on the environmental aspects and advantages of secondary aluminium. The areas of application in architecture are also widely known. But aluminium has not exhausted its possibilities as a resource: the metal also contributes to an important development in quantum computers. Qubits ...
The porous aluminium oxide layer that is present after anodising or colouring is still unsealed. This state would not provide long-term protection, e.g. on building surfaces. Subsequent sealing of these layers is therefore essential for long-term protection. In addition to the frequently used hot sealing, it is also possible to ...
Energy costs have been rising in many countries around the world in recent months. Electricity and gas prices in particular are affected by enormous price increases. But what can anodising companies do about this cost increase in the short term? There are some ways to make your own processes more ...
In classical, electrolytic colouring of aluminium surfaces with tin salts, uniform colourings from bronze to black are obtained with correct operation and the right colouring bath settings. However, sometimes you can observe inhomogeneous colouring on the goods carrier, so that a glance at the goods is enough to recognise the ...
Small cause - big effect : Mistakes when cleaning in anodising operations Small cause - big effect : Mistakes when cleaning in anodising operations Schon kleine Fehler beim Reinigen von Aluminiumoberflächen können im Eloxalbetrieb zu nicht verkaufsfähiger Ware führen, wenn man nicht aufpasst. Es lohnt daher immer, einen Blick auf ...
On anodised, electrolytically black-coloured and hot-sealed aluminum we see deposits - what could that be? After hot sealing, deposits are often visible on anodised and coloured surfaces, which are then quickly classified as so-called " sealing smut". However, if closer inspection reveals that all sealing conditions were in order, the ...
