Title: Innovations of Reinhard Gradl: A Pioneer in Crystalline Sodium Silicates
Introduction
Reinhard Gradl, located in Erftstadt, Germany, is a notable inventor with a significant portfolio of 33 patents. His work primarily revolves around the innovative processes for the preparation of crystalline sodium silicates, which have diverse industrial applications.
Latest Patents
Gradl’s latest patents focus on the advanced methods for producing crystalline sodium silicates. One of his notable inventions describes a process for the preparation of crystalline sodium silicates with a sheet structure and an SiO₂/Na₂O molar ratio ranging from 1.9:1 to 3.5:1. This process begins by treating waterglass solutions with a solids content between 20% and 65% by weight in a spray-drying zone. The outcome is a pulverulent amorphous sodium silicate with a maximum ignition loss of 20% by weight and a waste gas temperature of at least 140°C. Following this, the spray-dried sodium silicate undergoes heating in an ignition zone at temperatures between 500°C and 800°C for durations of 1 to 60 minutes, utilizing at least 10% by weight of recycled material. This recycled material is derived from mechanically comminuted crystalline sodium silicate that has exited the ignition zone.
Additionally, Gradl has developed a patent for the preparation of crystalline sodium silicates embodied in the formula Na₂SiₓO₂ₓ₊₁, where x ranges from 2 to 3. This process involves fusing sand and soda in specific molar ratios at elevated temperatures between 1200°C and 1400°C, followed by multiple steps of grinding and treatment in a reaction zone.
