Title: The Innovations of Hans Wilski
Introduction
Hans Wilski is a notable inventor based in Bad Soden am Taunus, Germany. He has made significant contributions to the field of materials and fluid dynamics, holding a total of 3 patents. His work focuses on enhancing the performance and usability of various materials and processes.
Latest Patents
One of Wilski's latest patents is for a package designed for dry-resist material. This innovative package is substantially impermeable to water vapor, which prevents humidity-related effects that can adversely influence the processability of photoresist materials. The package can be constructed from film tubing, with ends that are closed by welding or gluing, into which a photoresist roll is placed. The film tubing can be made from a composite material, including a polyester film as the support film, laminated with aluminum foil or vacuum-metallized aluminum, topped with a polyethylene film. Alternatively, a tinplate container can be used, which is sealed by soldering after the photoresist material is placed inside. These packages typically exhibit a permeability to water vapor of less than 0.01 gram per square meter per day, under specific humidity and temperature conditions.
Another significant patent involves the use of drag-reducing agents. This process aims to reduce the friction pressure drop of aqueous liquids and suspensions in turbulent or pulsating flow. By adding between 1 to 1,000 ppm of linear random copolymers, Wilski's method effectively enhances fluid dynamics. The copolymers are designed to be dimensionally stable jellies that maintain their solubility in water, providing a practical solution for various industrial applications.
