Obtaining microcrystalline cellulose based on biodamaged wood as a way to improve the sanitary and forest pathological state of forests

Abstract

The paper-forming properties of the fibrous suspension and the physical and mechanical characteristics of the finished types of paper largely depend on the type of initial plant material. Depending on what purpose it is necessary to obtain paper, a composition is made from fibrous semi-finished products of plant origin in various proportions. Basically, paper is produced from two, three, or more fibrous semi-finished products, forming a paper composition according to the type of fibers, and sometimes from one fibrous semi-finished product, suitably prepared for this. The properties of the original fibrous semi-finished products to a large extent affect not only the properties of the finished paper, but also determine the technological mode of their processing. This paper shows the possibility of obtaining cellulose from biodamaged wood. The mechanical strength characteristics of the finished castings are analyzed after grinding the fibrous mass on a knifeless grinding plant of the “jet-barrier” type. The conditions for obtaining microcrystalline cellulose from biodamaged wood are determined.
