« Separating Solvents and Other Applications of Fractionation Methods » In chemistry, fractionation refers to the process of separating mixtures into their individual components. This is achieved using a variety of specialized chemical separation techniques. The term “fractionation” is typically …

« Using Defoamers in Industrial Applications » Foam formation is a common issue in many industrial systems. In such cases, defoamers are needed to either suppress or prevent foaming altogether. This article offers an overview of how foam forms and …

Oils and greases temporarily protect metal surfaces from corrosion during storage and processing. Long-term corrosion protection, however, is only achieved through surface technology. Specialized coatings act as barriers, preventing environmental factors from reaching the metal. The prerequisite is that surfaces …

The adhesion of coatings and the durability of adhesive bonds depend largely on the condition of the surfaces involved. Pre-treatment gives a material the surface characteristics necessary for successful downstream processing. Surface treatment uses various pre-treatment methods depending on the …

To develop effective methods for reducing friction-related losses of material and energy, it is necessary to develop a clear understanding of the mechanisms underlying friction and wear. In this context, the term “tribosystem” was introduced. The prefix ‘tribo-‘ derives from …

Bulk transportation of feed, chemicals, petroleum products, and foodstuffs often takes place in tank trucks. To ensure that goods arrive safely at their destination in top condition, thorough tank truck cleaning is essential — both at regular intervals and every …

Water beads up on many surfaces. After a rain shower, tiny droplets can still be seen on windows for a long time.  This occurs because thin water films contract into droplets. All these are effects of surface tension, which becomes …

Wherever the word “duplex” appears, it usually refers to something double-layered. In surface technology, duplex systems are no exception—they consist of two protective layers to defend against corrosion. The bottom layer is created through hot-dip galvanizing, while the top layer …

« How to Identify Starting Points for Reducing Greenhouse Gas Emissions » Global warming is arguably the greatest threat of our time. Looking at prehistoric periods, we see that during every major climate shift, the species that went extinct were …

« A Brief Overview of the process » Anodizing is a process that provides aluminum semi-finished products (partially processed materials) or workpieces with a corrosion-resistant and wear-resistant surface. This protective layer is formed with the aid of an electric current …
