VISUAL AND ELEMENTAL ANALYSIS OF NON-FIBRE INCLUSIONS IN TISSUE-PAPER FROM RECOVERED PAPER IN THE CONDITIONS OF THE ENTERPRISE OF SYKTYVKAR TISSUE GROUP OJSC
UDC 66.023.2
Abstract
The article is devoted to solving an important scientific and technical task, improving the technology of production of tissue-paper. The study pays special attention to the problems related to the use of recovered paper, microscopic images of the surface of samples obtained from recovered paper sampling at various stages of the production of tissue-paper at the enterprise of Syktyvkar Tissue Group OJSC are presented. The main result of scientific research was a preliminary assessment of the study of the recovered paper stock preparation technology at the enterprise, for which the sampling from various stages of production were examined by a scanning electron microscope, which made it possible to visually assess the degree of cleaning of recovered paper from impurities from images of the microstructure of the surface of various scales. The chemical composition of the main additives was established by energy-dispersive X-ray spectral micro assay (EDX). Preliminary assessment of the nature of contamination, visual assessment of the microstructure of samples obtained from recovered paper stock from various stages of cleaning, allowed the engineers of the enterprise to evaluate the effectiveness of individual units of the stock preparation department for the production of tissue-paper. The obtained data will make it possible to specify the scientific and technical task and direct subsequent scientific work to improve the recovered paper stock preparation unit, which more requires perfection.
