Органоминеральные целлюлозные композиционные материалы информационного назначения (офисные виды бумаги)

Abstract

The main stages of the production of organomineral cellulose composite materials (CCM) for informational purposes (office types of paper) have been examined. The possibility of transfer to a resource-saving adaptation technology by molding paper from a mixture of partially bleached cellulose, bleached chemical-thermomechanical pulp and a mineral filler — precipitated calcium carbonate (Precipitated Calcium Carbonate — PCC) — with the creation of a new type of office paper — ECO paper, is shown. The change in the nature of inter-fibrillar and inter-fiber bonds during the transition from bleached cellulose to partially bleached was analyzed. The morphological features of these semi-finished products, as well as the optical and physic-mechanical properties of the resulting paper have been studied. The problems of directional changes in the zeta potential of the paper mass are identified when the nature of paper-forming fibers changes. On an industrial papermaking machine (PMM) with a capacity of more than a thousand tons per day, pilot production and transfer of PMM to mass production of new types of paper, with appropriate addition of existing standards, were carried out.
