Title: John Richard Holland: Innovator in Fire Resistant Glazing Technology

Introduction

John Richard Holland is a notable inventor based in Ormskirk, GB. He has made significant contributions to the field of fire resistant glazing, holding a total of 10 patents. His innovative work focuses on enhancing the safety and performance of glazing materials used in various applications.

Latest Patents

Holland's latest patents include advancements in fire resistant glazing technology. One of his key inventions is a fire resistant glazing that comprises a fire resistant interlayer based upon a silicate waterglass. This innovative glazing is characterized by the incorporation of aluminum ions, which are introduced as a solution partially neutralized using hydroxycarboxylic acid, preferably citric acid. The incorporation of aluminum significantly improves the fire resistance and impact properties of the glazing.

Another notable patent is a method for producing fire resistant glazings with enhanced properties. This method involves a silicate-based interlayer containing 35% to 43% by weight of water, produced using a cast in place process. The water content in the interlayer is reduced by concentrating the silicate solution or by introducing silica in the form of a silica sol. The use of a mixture of an aqueous sol and an organosol, along with polyhydroxy compounds and saccharides, further improves the properties of the interlayer while reducing water content. The resulting silicate-based formulations are pourable and can be cured to form an optically clear interlayer.
