Title: The Innovations of Alf Hugo Karlsson
Introduction
Alf Hugo Karlsson, a notable inventor based in Njurunda, Sweden, has made significant contributions to the field of cellulose derivatives and fuse sizes. With a total of three patents to his name, his innovative work reflects a deep understanding of material science and manufacturing processes.
Latest Patents
Among Karlsson's latest patents is a groundbreaking method of manufacturing cellulose derivatives. This invention discloses an absorbent cellulose material that comprises a substituted cellulose, characterized by an average degree of substitution low enough to render the material insoluble. The process enhances the surface area of the fibers by bursting them during drying, thereby increasing the material's absorbency. Additionally, the method includes the steps of swelling the material, fixing it in its swelled state, and drying it while preventing shrinkage, leading to superior functional properties.
Another significant patent by Karlsson focuses on the preparation of an improved fuse size. This invention combines urea with carboxymethyl cellulose, along with added starch, to enhance performance. The method involves heating the mixture of urea and carboxymethyl cellulose before incorporating an oxidizing agent in the presence of a metal ion, specifically bivalent iron, added in its lower oxidation stage. In a preferred embodiment, hydrogen peroxide serves as the oxidizing agent, making this invention both innovative and practical.
