Hydromechanische Entkalkung unter Verwendung von Kesselstein als Abrasivmedium als Alternative zum Beizen mit Säure

Das Beizen mit starken Säuren wie Salz- oder Schwefelsäure zur Entfernung von Kesselstein nach dem Warmwalzen kann durch eine nicht-chemische Methode ersetzt werden. Ein deutsches kleines oder mittleres Unternehmen (KMU) entwickelte eine Alternative, die Wasserstrahlen und als Abfall anfallenden Kesselstein als Abrasivmedium verwendet. Die Vermeidung von Chemikalien und die Senkung der Kosten sind die Vorteile der Alternative.

Water-based technology to produce polyurethane and polyester/polyamide microfibers

Nonwoven polyurethane and polyester/polyamide based microfibers (generally known as suede) are increasingly used in many fields of application and in a diversity of products. The most used and popular technology for the production of nonwoven is a method involving different solvents and processing aids during the production in order to give the fibres the physical and mechanical characteristics required. This case story describes an alternative technology to produce microfibers using water as the only solvent. The technology, called Dinamica®, developed by Miko and patented by the Japanese partner Asahi Kasei also gives the materials flame retardant properties without the addition of chemical flame retardants.
