Alfiseal 942 – Easy – Seal AL Process You need a hot sealing additive that will achieve clean, dry-to-handle surfaces with “anti-fingerprint” properties? Perhaps you are looking for an additive that meets all the Qualanod requirements and ensures the long-term stability of your sealing bath? Or maybe you need a special hot sealing product that
In the treatment process of aluminium – for example in anodising – a clean surface is very important. The following question often comes up: how can we check if an aluminium surface is free of grease and oil when it comes out of the cleaning bath? Certainly, this can be checked with analytical equipment in
Environmental protection and the search for more compatible processes have also had a strong influence on pre-treatment. In the past, chromium VI compounds were used to provide good corrosion protection and, due to the chemical composition of these baths (chromium(VI), conductivity values of about 8000 µS/cm and a strongly acidic pH value), a low-germ background
The pre-treatment of aluminium surfaces in alkaline E6 long-term pickling processes produces fine-matt, very decorative surfaces. However, this appearance is negatively affected by the accumulation of certain contaminants to such an extent that the anodised product is often not saleable and has to be reworked. In addition to the known zinc impurities that lead to
Sometimes, at the start of production, you observe the following phenomenon on the cleaning bath at the beginning of the week: An oil-like, yellowish or brownish layer floats on the surface of the cleaning bath and you wonder what it is. At first, one will suspect oil residues that have separated from the bath, e.g.
Everyone knows them, at least since electric mobility became the topic of our century: The lithium-ion battery. Thanks to its high capacity, chargeability and service life, it is generally regarded as the battery for electrical technology. But there is one element that seems even more suitable: aluminium. Yes, that’s right. Aluminium is proving to be
