Title: Brian Frederic Satterfield: Innovator in Paper Production Technologies
Introduction
Brian Frederic Satterfield is a notable inventor based in Columbia, SC (US). He has made significant contributions to the field of paper production, holding a total of 3 patents. His innovative approaches have advanced the methods used in creating filled paper and dewatering aqueous suspensions.
Latest Patents
Satterfield's latest patents include the production of filled paper and compositions for use in this process. This filled paper is created by adding a cationising amount of cationic polymer to precipitated calcium carbonate or other fillers, either as a slurry or in a thick stock component. This process results in a thin stock containing the cationised filler, which is then treated with a formaldehyde resin and polyethylene oxide as a retention system prior to drainage and drying. Another significant patent involves the dewatering of aqueous suspensions. In this process, a mill waste or deinking waste containing cellulosic material and hydrophobic material is flocculated by a cationic polymeric flocculant. The flocculated material is then aggregated by a swelling clay or other anionic colloidal material, and the aggregated material is separated by belt pressing or other pressure filtration as a cake.
