Abstract
The present work focuses on the effects of sodium percarbonate and hydrogen peroxide as reinforcing agents for the oxygen delignification of old corrugated container paper (OCC). The chemical and crystalline structure, physical and mechanical properties and the optical properties were investigated in OCC papers delignified using reinforced oxygen delignification methods. The relative degradation rates were determined at 4.02% for oxygen delignification reinforced with sodium percarbonate and 0.62% for oxygen delignification reinforced with hydrogen peroxide at a 2% alkali charge. The results showed that paper sheet properties following oxygen delignification reinforced with hydrogen peroxide were better than for those following oxygen delignification reinforced with sodium percarbonate and pure sodium percarbonate. It was determined that the whiteness value was higher following oxygen delignification reinforced with sodium percarbonate rather than any of the other reinforcing agents, while the highest ISO brightness value was found following oxygen delignification reinforced with hydrogen peroxide.
期刊介绍:
Wood. Research papers. Reports. Announcements" ("Drewno") is an international scientific journal that publishes original results of innovatory basic and applied research concerning technological, technical, economic and ecological issues important for the wood science and forest-based industries, including their environment, and interesting to the international recipients. "Drewno" is an Open Access biannual journal.
Aims and scope:
wood science: anatomy, biology, chemistry, physics
wood mechanical and chemical technology, inter alia, sawmilling, composite wood products, wooden construction, furniture making, wood pulp, paper making
material engineering, biocomposites, nanocomposites
material management
environmental protection, safety of the processes, products and working stations
biotechnology
bioenergy, biofuels
forestry: harvesting and wood quality
wood-based industries economics
The Editorial Board of the journal especially welcomes articles concerning increase in wood resources (wood mobilisation); innovative composites and lignocellulosic materials; new trends in the protection, modification and finishing of wood; biorefining of raw wood material; "green" building; new technologies of wood waste recycling; sustainable development; innovation management; and business networks.
