Title: Innovations in Paper Production by Chengliang Jiang
Introduction
Chengliang Jiang is a notable inventor based in Duluth, GA (US), recognized for his contributions to the field of paper production. With a total of 5 patents, he has developed innovative methods that enhance the efficiency and sustainability of paper manufacturing processes.
Latest Patents
One of Jiang's latest patents focuses on the enzymatic treatment of virgin fiber and recycled paper to reduce residual mineral oil levels for paper production. This invention provides compositions comprising enzyme formulations that effectively treat virgin fiber and recycled wastepaper containing mineral oils. The mineral oils typically originate from wastepapers with mineral oil-based inks and other hydrocarbon-based chemistries used during manufacturing and packaging processes. The enzymes in Jiang's compositions break down or modify the mineral oils present in the fiber and paper, facilitating their removal during recycling, pulping, and papermaking processes. This method results in pulp and paper products with significantly reduced mineral oil concentrations, making them safer for food packaging applications.
Another significant patent by Jiang involves increasing enzyme stability and activity for pulp and paper production. In this method, wood pulp is treated with an esterase formulation combined with a metal ion or cationic polymer. This treatment enhances the stability and activity of esterase enzymes under high temperatures and extreme pH conditions. The application of this method can effectively address pitch problems in pulp, thereby improving the overall quality of paper produced.
