« What Methods Are Used? » Plastics are widely used as packaging materials, insulators, components in various machines and devices, and as coating agents. Unfortunately, their widespread use has led to increasing environmental concerns as they are now frequently found …

Decarburization refers to the reduction of carbon content in molten or solidified alloys. This process commonly occurs during the production and processing of steel but can also affect cast iron when exposed to  elevated temperatures. This article explains the role …

« 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 …

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 …

« 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 …

« How to Manage Paint Systems Effectively » The paints used in surface technology change their physical state during processing. The raw materials are in liquid form or are at least flowable so that they can completely cover the surface. …
