Application of Colloidal Chemistry and Polymer Chemistry in Papermaking Industry

Colloidal chemistry is a science to study the physicochemical properties of generalized colloidal dispersion systems. Polymer new comprehensive subject that studies synthesis, chemical reaction, physical chemistry, physics, processing and application polymer compounds. The development mainly experienced four periods: utilization natural polymers, modification production synthetic polymers establishment science. Since 1930s, with related sub disciplines such as reaction kinetics, thermodynamics, structural physics biopolymers have been gradually established, forming systematic Papermaking industry an industrial sector manufactures all kinds paper paperboard. It includes pulp manufacturing uses wood, reed, bagasse, straw, wheat cotton hemp stalk, other raw materials manufacture pulp, paperboard industry, produces coated, polished, glued, laminated font plate. Paper important closely national economy construction social civilization. This focuses on relationship between papermaking especially its in cooking, washing, bleaching, water treatment, introduces detail current situation trend flocculation method for wastewater according theory.
