METHOD FOR PRELIMINARY TREATMENT OF FIBROUS MATERIAL INTENDED FOR APPLICATION IN PRODUCTION OF PAPER, CARDBOARD AND SIMILAR PRODUCE, AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC D21H17/70

Abstract RU 2346097 C2

FIELD: textile fabrics, paper.

SUBSTANCE: method is intended for preliminary treatment of fibrous material in production of paper, cardboard and similar produce. Fibrous material is preliminarily treated in mixer of transmission type, which works according to principle of impact mill. Then fibrous material is supplied in the form of crushed liquid fractions or solid substance into precipitating reactor. Gas is also supplied there to create gas space. Gas comprises substance, which assists in precipitation of mineral substance, for instance, carbon dioxide (CO₂). Device comprises precipitating reactor and additional activating device that provides for more intense capability of fibers to connect to each other and to precipitated mineral substance. Device may be easily inbuilt into production process of paper manufacture.

EFFECT: highly efficient precipitation of mineral particles on fiber with provision of specified paper properties.
