Title: Innovations by David William Holden
Introduction
David William Holden is a notable inventor based in Wigan, GB. He has made significant contributions to the field of fire-resistant materials, holding a total of 11 patents. His work focuses on enhancing the safety and performance of glazing materials used in various applications.
Latest Patents
One of his latest patents is for fire-resistant glazing, which comprises a fire-resistant interlayer based on silicate waterglass. This innovative glazing is characterized by the incorporation of aluminum ions, which are introduced as a solution partially neutralized with hydroxycarboxylic acid, preferably citric acid. The addition of aluminum enhances the fire resistance and impact properties of the glazing. Another significant patent involves a method for producing fire-resistant glazings with improved properties. This method utilizes a silicate-based interlayer containing 35% to 43% by weight of water, produced through a cast-in-place process. The water content in the interlayer is reduced by concentrating the silicate solution or by adding silica in the form of a silica sol. The formulations are designed to be pourable and can be cured to form an optically clear interlayer.
