Title: Roderick Collins: Innovator in Papermaking Technology
Introduction
Roderick Collins is a notable inventor based in Pierrefonds, Canada. He has made significant contributions to the field of papermaking through his innovative approaches to filler treatment processes. With a total of 2 patents, Collins has developed methods that enhance the efficiency and quality of paper production.
Latest Patents
Collins' latest patents focus on latex-treated filler slurries for use in papermaking. The first patent describes a filler treatment process that enhances the fixation of anionic latex on filler in a short time. Anionic polymer dispersions (latex) are added to papermaking filler slurries at ambient temperature and then mixed with water at a temperature higher than the glass transition temperature (Tg) of the latex used. This process ensures that the anionic latexes are totally and irreversibly fixed onto the filler particles, resulting in a stable aggregated filler slurry. This slurry can be added to papermaking furnishes at any point prior to the headbox of the paper machine or stored for later use. The treatment improves filler retention, slightly reduces sheet strength, and enhances sizing performance.
The second patent outlines a continuous filter treatment process where anionic polymer dispersions are added to common papermaking filler slurries at ambient temperature. The mixture is then heated to a temperature 30-60°C higher than the Tg of the latex. The chemical composition of the resin and the type of surfactant used during the emulsion polymerization process are crucial for efficiently fixing the latex onto the filler. This method also results in a stable aggregated filler slurry that can be used in various types of paper production, including fine papers and multi-ply paperboards.
